fertility testing

Intro 

If you're thinking about freezing your eggs and you've started to gather information about it, you're probably coming across a lot of information. This can definitely be overwhelming but there’s no need to panic! We're here to help you figure out if egg freezing is the right choice for you, no matter what age you are.

What is egg freezing?

Before we dive further into this topic, what is egg freezing? Egg freezing, known as oocyte cryopreservation in the medical world, is a technique used to preserve someone’s fertility.  Eggs are collected from the ovaries and frozen so they can be used in the future. If the person is unable to get pregnant naturally, the eggs are unfrozen and used in an assisted reproductive technology (ART) procedure, like in-vitro fertilization (IVF). Whether you know you want to have kids or you aren’t sure and want to give yourself more time to figure it out, think of egg freezing as a way to keep your options open for the future.

Should I freeze my eggs?

There are many, many reasons why someone might choose to freeze their eggs but the decision is a deeply personal one that requires some careful consideration. When making that decision though, it’s important to know that egg freezing is not an “insurance policy” for your fertility. While egg freezing can take some of the stress of having a baby right now off your shoulders, it is not a guarantee that you’ll have a baby in the future. 

Why not? Well, not all the eggs that get frozen will actually be viable. It’s expected that some eggs will not survive the warming process. In addition, the chances of the eggs that do survive being successfully fertilized depends partially on how old you were when you froze them (more on this later). Beyond that, fertility and pregnancy risks change with age. If you freeze your eggs at 30 and use them when you're 40, you'll have to deal with the realities of pregnancy at 40.

This is not to sway your decision one way or another. Ultimately, only you and your doctor can decide if egg freezing is the right decision for you. But it's important to go in knowing that it’s not meant to be a done deal.

Pros of egg freezing

Ok, now that we’ve gone through the basics, let’s discuss the pros and cons.

Perhaps the biggest advantage of freezing your eggs is the fact that it lowers the risk of having children with genetic abnormalities associated with ovarian aneuploidy. Ovarian aneuploidy refers to when an egg has an abnormal number of chromosomes which leads to an abnormal pregnancy. Most people are born with 46 total chromosomes (23 pairs). The most common aneuploidy risk seen by far is Down syndrome. Babies with Down syndrome have an extra copy of one of these chromosomes, chromosome 21. The medical term for having an extra copy of a chromosome is “trisomy” so Down syndrome is also known as Trisomy 21. Freezing your eggs at a younger age decreases (but does not totally eliminate) the risk of an abnormal number of chromosomes.

Another benefit of egg freezing is that it puts the decision-making power entirely in your hands. Whether you’re freezing your eggs because you want to focus on your career or you’re getting a medical treatment that may affect your fertility later on or you’re waiting to find the right partner, freezing your eggs allows you to preserve some of your fertility independently. 

Egg freezing also gives you options in terms of having your own biological children. Of course, there is the obvious option of having the eggs fertilized and the embryos implanted into your uterus. But you also have the option of having those embryos implanted into a gestational carrier or into your partner if they have uterus. 

Finally, freezing your eggs does not affect your ability to get pregnant naturally. The egg freezing process and retrieval procedure simply rescue eggs that would have died with your next menstrual cycle. This means it does not affect your ovarian reserve (the number of eggs in your ovaries). Once you’ve completed the full process, your body will continue to ovulate and release an egg each month like normal.  

Cons of egg freezing

Now, let’s talk about the disadvantages of egg freezing. 

The most obvious downside is the cost. While some insurance plans may cover egg freezing, this isn’t the case most of the time. The out-of-pocket cost of egg freezing varies but it can be up to $20,000 depending on where you are and which clinic you use. This typically includes bloodwork, medications, ultrasounds, and the egg retrieval procedure. This does not include the annual storage fee (which can be up to $800 per year) and any follow-up procedures if you end up using those eggs. Learn how you can freeze for free with Freeze by Co. 

The next thing to consider is the hormone medications and egg retrieval process themselves. These medicines not only require injecting yourself (or having a partner or friend do it) but they can have some not-so-fun side effects. These can include fatigue, nausea, bloating, headaches, abdominal pain, breast tenderness, and irritability. A severe risk of hormone medications is ovarian hyperstimulation syndrome (OHSS). This condition can lead to blood clots, shortness of breath, abdominal pain, dehydration and vomiting. It may even require admission to the hospital to manage. Thankfully, OHSS is rare nowadays, affecting only up to 2% of patients.

The egg retrieval process is quick and the most common symptoms afterwards are pelvic or abdominal pain, constipation, bloating, and spotting. The main concern here is the time you need. One typical egg-freezing cycle can range from 10 to 14 days and during that time you'll be attending doctor appointments almost daily to make sure your eggs are maturing correctly.

If you’re taking any gender-affirming hormones like testosterone, you may need to take a break in order to freeze your eggs. One study showed that transgender men who used gender-affirming hormones and stopped a few months before fertility treatments ended up with the same number of eggs as cis women. But getting off hormones can be hard and could trigger gender dysphoria so the best option is to freeze eggs before transitioning if at all possible.

No one likes to be the bearer of bad news but this is an important one. Egg freezing may mean your eggs stay the same age forever but unfortunately, your body does not. As you age, the risks of pregnancy increase for both you and your potential child. These risks include gestational diabetes, preeclampsia, c-section delivery, preterm delivery of a baby with low birth weight and other risks related to the pregnancy being IVF. However, these risks vary widely depending on many other factors. 

One final caveat to remember is that egg freezing does not guarantee a live birth. It’s likely that not all eggs will survive the thawing process. Some will not fertilize. Others fertilize abnormally, and still others don’t implant successfully in the uterus. A large study at NYU in July 2022 showed a 39% live birth rate for people who used their frozen eggs. The two factors that affected the success rates the most were age at the time of egg freezing and the number of eggs thawed. Specifically, the live birth rate was over 50% for people who thawed at least 20 eggs or who were under 38 when they froze their eggs. Which brings us to our next question: what age is best for egg freezing? 

When should I freeze my eggs? 

Let me start by saying that there is no perfect age at which to freeze your eggs. However, the TL;DR is that the younger you can do it, the better. According to the American Society for Reproductive Medicine (ASRM), an optimal time to freeze your eggs is in your 20s and early 30s, while you have a higher ovarian reserve and eggs are healthier. So whether you’re 25 or 35, you can absolutely freeze your eggs!

A large 2020 study at a fertility clinic that specializes in this area looked at egg freezing cycles for over 1,200 people. It compared the average number of eggs people of different ages were able to freeze versus the “optimal” or goal number of eggs they should freeze. This goal number was based on how many eggs would give them a 70% live birth rate after doing 1 or 2 egg freezing cycles (this rate is calculated using some other numbers and it typically goes up as we age to make up for the lower number of healthy eggs). 

The study found that younger people, unsurprisingly, have an easier time freezing the goal number of eggs in one cycle. As people aged, they needed multiple egg freezing cycles to reach that goal number.

These findings bring up a common question–is it worth freezing eggs after age 35? Well, it depends. The ASRM does not recommend egg freezing for people older than 38, but this isn’t a strict cutoff. Everyone’s fertility goes down at a different rate. Having your fertility hormones checked can sometimes help you and your doctor get a general idea of what your ovarian reserve is. This can better help you decide if egg freezing is right for you.

Egg freezing can be a tricky process to navigate and you are not alone when it comes to questions and concerns around it. Freeze by Co is here to help you every step of the way. With our Split program, people between 21 to 34 years old have the chance to freeze their eggs for free! In a “Split” cycle, you would donate half of the eggs retrieved to a family that’s trying to conceive and freeze the remaining half for yourself. If you’re over 34, you can still participate in the Keep program up to age 40. You would be able to freeze your eggs and keep them all for yourself, on your timeline while having access to an additional valuable resource in our support community, The Nest. This community allows you to engage with other people freezing their eggs at the exact same time! 

Regardless of which path you choose, our team will be there to guide you through the process as we work to keep your family-building options on the table.

It may not come as a surprise to learn that the prime time for freezing your eggs is actually a lot earlier than you think. According to the American College of Obstetrics and Gynecologists (ACOG), freezing your eggs while you’re still in your 20s can help boost your chances of a successful pregnancy—and a 2010 report from the Center for Disease Control and Prevention (CDC) says that those eggs have a higher chance at resulting in a live birth no matter your age when you decide to start your family. 

For many women, that means the best time to freeze their eggs is likely the moment they start wondering when they should start. Read on to see what you need to know about why freezing your eggs before you’re even sure what you want to do with them is the best way to ensure you’ll be able to make the decision for yourself when the time is right. 

Your body produces a different number of eggs at different times

Your late 20s and early to mid-30s are considered the peak time to retrieve eggs—with a 2015 study from the American Society for Reproductive Medicine saying you’ll see the best results prior to the age of 34 — because your body has reached complete development and your eggs are at their most healthy and plentiful point.

That doesn’t mean that the quality of your eggs takes a major dip when you celebrate your 38th birthday. Instead, it means that as you add more and more candles to your birthday cake each year your body begins to produce fewer eggs. This becomes important when you realize how many eggs you’ll need to retrieve when you begin the process of freezing your eggs.  

Take the 2020 study from Assisted Reproduction Technologies (ART) that showed women under the age of 35 were retrieving an average of 21 eggs during their first round of egg freezing while women between the ages of 35-37 were retrieving an average of 17. Four eggs may not seem like that big of a difference at first, but once you take into account how many eggs experts say you should have on hand when it comes time to start fertilization you’ll begin to realize just how quickly those numbers add up. 

Producing fewer eggs may increase costs

The saying less is more doesn’t apply too much in the world of fertility, where your chances of going on to have a live birth increase based on the number of eggs you have on hand when it comes time to fertilize and implant them. 

That 2020 ART study that showed the average number of eggs retrieved each cycle also showed that if you're under the age of 35 you will need 9 eggs for a 70% chance at having a baby. However, if you’re looking to hit that same 70% mark in your later years (think 38-40), you’ll need closer to 18 eggs to have the same chances at a live birth. With women in that age range only averaging 17 eggs per retrieval, that may mean multiple cycles, and with a $10,000-20,000 price tag that can quickly add up.

The best time to freeze your eggs is, unfortunately, usually before you can afford it

Not many people have that much money readily available in their 20s, which is why egg freezing is often financially out of reach for those who would benefit most from it. With programs like Freeze by Co you can take advantage of those peak fertility years even if you can’t exactly swing the costs. 

One program offered by Freeze by Co is Split. Split Members benefit by offsetting the cost of freezing their eggs by donating half of them to a family that cannot otherwise conceive. Split Members match with intended parents, and undergo an egg freezing cycle where half of their eggs are donated to the perfect intended parents (after testing and meeting qualifications, of course). The other half are then stored (for free) for the split member for up to 10 years. 

If you’d rather hold onto all your eggs until you’ve decided what your fertility future holds, you can use Freeze by Co’s Keep Member plan. These members can still benefit from lower costs, thanks to things like reduced medication fees, consultation discounts, and more. 

This is the most cost-effective age to freeze your eggs

With all these numbers flying around you may be wondering where the health benefits and the financial benefits meet. According to a 2015 study published in the journal Fertility and Sterility, the two numbers seem to cross paths at the age of 35.

Women who freeze their eggs at 35 for use by the age of 40 spend an estimated $15,000 less than those who are trying to have a baby at 40. And that’s not the only good news, that math seems to hold up all the way until the age of 38. 

Freezing your eggs should be a positive experience

With the accessibility Cofertility gives women to take control of their fertility process, you can feel empowered to make decisions based on what’s in the best interest for you and your body without having to worry about your bank account. 

Getting an earlier start at freezing your eggs through Freeze by Co (even if you don’t have a partner or aren’t even sure that your dream future includes children yet) will: 

• Give you a higher chance at eventually achieving a live birth even if you wait until your late 30s or early 40s.
• Allow you to wait on making major decisions about your education, career, and future until you’re ready.
• Offer you the freedom to make medical decisions based on what’s right for you instead of what type of coverage your employer offers at the time. 
• Provide peace of mind because no matter what your future family may look like you’ve already taken the first step to making your dreams a reality. 

Even if you’ve missed that peak window into your fertility there are still plenty of benefits to freezing your eggs. With all of the new plans offered by Freeze by Co you’re likely to find one that will fit your current needs while giving you a chance to plan for your future.

Many folks who have made the big (and exciting) decision to freeze their eggs want to improve their egg quality before freezing. But is egg quality really something you can control? What kinds of lifestyle changes should you make before freezing your eggs? Read on for a look at what the research says about egg quality — and what you can do to improve it before the egg freezing process begins. 

What is egg quality?

As you’ve been exploring the egg freezing process, you may have heard your fertility doctor mention that freezing during your 20s can be beneficial because your egg quality will likely be higher. 

It’s annoying, but true: as women age, our egg quality typically goes down further and further. The American College of Obstetricians and Gynecologists (ACOG) estimates a woman’s chances of getting pregnant begin to decrease at age 32 and continue to gradually go down until about age 37 when the decrease becomes more rapid. ACOG links this decrease in what they call fecundity — another word for fertility — to egg quality. 

This is one of the many reasons Freeze by Co partners with local fertility clinics to create opportunities for women in their 20s to freeze eggs more affordably. We want you to have more control over your reproductive choices, even if you’re not looking to get pregnant during this peak egg quality period.

But what does “egg quality” (also called oocyte competence) actually mean? Are doctors being a tad judgmental about a woman’s age? Not at all. 

When fertility specialists use this term, they’re referring to whether your eggs are considered genetically normal or abnormal, and it’s tied pretty closely to the chances that an egg could ever result in pregnancy.  

Euploid vs. aneuploid embryos 

While sperm health is undeniably important, it all starts with the egg. The quality of embryos made from your eggs comes down to two different types:

• Euploid embryos 

• These embryos are genetically “normal.” 
• They contain the right number of chromosomes at 46. 

• Aneuploid embryos

• These embryos are genetically “abnormal.” 
• They contain either fewer or more chromosomes than normal. 
• Embryos created with a low quality egg may inherit either too many or too few chromosomes. 
• Most aneuploid embryos will either fail to implant or result in miscarriage as they are usually not compatible with life. 

There’s also a significantly higher risk that an aneuploid embryo will not implant in the uterus after an in vitro fertilization (IVF) transfer — one study found as much as 96 percent of abnormal embryos transferred into the uterus did not implant. On the other hand, that same study found when euploid embryos were transferred, the pregnancy rate was 82 percent. 

Do I need to improve my egg quality before freezing? 

So if euploid embryos start with healthy eggs, you’re probably wondering: do I need to improve my egg quality before freezing? 

Some factors that affect egg quality such as your personal genetics and the passing of time can’t be controlled. But there are ample steps you can take to influence the health and quality of your eggs. 

Here are some simple changes that research shows may improve egg quality. We recommend you consider making these changes at least three months prior to egg freezing: 

1. Quit smoking 

If you’re using cigarettes, now is a good time to stop. Studies have found that smoking can have a detrimental effect on fertility. Puffing on cigarettes can increase the risk of infertility by as much as 60 percent with negative effects on the menstrual cycle, uterus, and ovaries. It’s the effect on the ovaries that is particularly troubling when it comes to egg quality with smoking damaging the DNA of the eggs themselves. 

2. Avoid marijuana

Although there aren’t a lot of studies on the effect of marijuana on fertility, those that exist indicate THC — the psychoactive ingredient in marijuana — can result in an impaired ability to produce viable embryos. According to a study published in the Journal of the Endocrine Society in 2020, the exposure of oocytes to THC was linked to a “significant decrease in the expression of genes called connexins.” These connexins are an important marker of egg quality. For our Split members, we require them to stop using marijuana products at least one month prior to retrieval.

3. Improve your diet

There is never a bad time to eat a healthy diet, and if you’re planning to freeze your eggs in the near future there are extra reasons to make smart choices at meal time. Eating a diet rich in leafy greens, whole grains, and lean proteins can all help those egg cells. 

Here are some rock star foods you might want to consider adding to your diet when you’ve got an eye on improving egg quality (plus the benefits they bring):

• Fish such as salmon, mackerel, and trout — Omega 3 fatty acids
• Egg yolks — Vitamin D
• Beans, oats, oranges, and cantaloupe — Inositol
• Fruits and veggies of any kind — Antioxidants
• Oysters, beef, chickpeas, lentils, hemp seeds, pumpkin seeds, and pine nuts — Zinc

Before embarking on any major diet changes, check with a registered dietician. They can help you craft a plan that’s just right for your body. 

4. Talk to your doctor about supplements

If you’re not already taking vitamins, you may want to chat with your reproductive endocrinologist about whether you should add Vitamin A, Vitamin B, folate and zinc — or maybe one of the four — to your daily routine. Studies have linked all three of these micronutrients to egg quality over the years, affecting the synthesis of DNA and other factors in oocyte development. 

Your doctor may want to check your vitamin D level with some bloodwork or go over your current vitamin regimen before deciding if adding on additional supplements is necessary. Make sure to bring any dietary changes you’re making into the conversation too — there can be too much of a good thing when it comes to some vitamins!

5. Talk to your doctor about your weight 

Being told you need to hop on the scale when you’re at the reproductive endocrinologist’s office can be frustrating, especially if you’ve struggled to lose or gain weight in the past, or if you have a condition such as polycystic ovarian syndrome (PCOS) that affects your weight. 

Still, the weight conversation is one worth having with your fertility specialist if you’re worried about your egg quality. Both being over and underweight has been linked to egg quality by researchers time and again. 

Obesity in particular has been found to affect the hormones that guide an egg as it matures. On the other hand, being underweight can stop the body from ovulating entirely. 

The “right” weight for your body is one you and your doctor can discuss. If changes are in order, they can help craft a plan for healthy changes — or recommend a dietician who can. For our Split program, there are BMI requirements, which you can read more about here.

The bottom line

The quality of your eggs may not be completely in your control, but you do have solid options when it comes to improving your egg quality before freezing. What you put into your body makes a difference, and making changes now can make a real difference down the line. 

Perhaps the idea of egg freezing is something that you’ve thought about before. For many of us, though, cost can be a big barrier. You might be hoping to find an affordable egg freezing program that can allow you to freeze your eggs now and store them without breaking the bank, as you pursue your own agenda.

Is this just a pipe dream? With Freeze by Co, it’s actually…not. Read about how our new option can enable you to give the idea of egg freezing another look, with—wait for it—free egg freezing. And you get to help a family along the way.

An affordable innovation

With some egg freezing programs, fees can run into the thousands initially and grow every year. But at Freeze by Co, it is our goal to make the process as affordable as possible. This led us to develop what we call our Split program.

With the Split program, if you are eligible, the premise is simple: for each cycle you undergo, you keep half of the eggs for yourself at absolutely no charge, plus up to ten years of storage, when you give the other half of the retrieved eggs to another family who can’t otherwise conceive. All of your medical expenses and travel related to egg freezing is covered as well.

What you get as a Split member

In addition to giving a life-changing gift to another family, as a Split member, you are entitled to the following for free with your egg freezing cycle:

• Testing
• Medication
• Egg retrieval
• Egg freezing and storage
• Procedure insurance
• Travel
  

In addition to lightening your own financial load, the good you’ll be doing will be immeasurable.

Is it a fit?

To participate in Split, you must meet certain industry- and government-based criteria, including: 

• Being between 21 and 33 years old. Age is a factor that contributes to waning fertility, which, while not true for everyone, tends to decline at age 35. Since the process leading up to egg donation can take time, we cap the program at age 33, as consistent with guidelines set by the American Society for Reproductive Medicine (ASRM). 
• Having two ovaries
• Enjoying good physical and emotional health, without any reproductive issues or genetic abnormalities
• Having a body mass index (BMI) between 18 and 29 to enable optimal medication administration and egg retrieval outcomes
• Having avoided smoking and recreational drug use or Depo Provera injection as a mode of birth control

To find out if our Split program is a way that we can help you reach your egg freezing goals, here’s how the process works:

Getting started

First, take our brief quiz to learn more about our Split program and see if you’re a potential fit. It just takes a few minutes. 

Applying for membership

Then, if you’ve pre-qualified, you move on to the application process. This is your chance to tell us more about your background and create a profile for intended parents to see and hopefully connect with. It will also help finalize your acceptance into the program.

The interview process

Next, we chat. You get to ask us any questions about the process and get to know us, as we get to know you as well. We’ll walk you through all program logistics and frequently asked questions so you feel completely comfortable with it all. 

Find a match

Once you’ve been fully accepted into the program, the matching process begins. When your profile has been selected by intended parents, you’ll have the opportunity to accept the match. If you agree it’s a good fit, then the screening and freezing process can begin.

Screening

During the screening phase, we’ll get a sense of your ovarian reserve and overall physical health to get a sense of whether you’ll have enough eggs available to fairly split for yourself and the intended parents. If your ovarian reserve appears strong enough that splitting the retrieved egg yield has the chance to result in a live birth for both parties involved, and you continue to qualify based on the other physical and psychological screening factors, you’ll be given the final green light.  

The cycle

Now it’s all about your cycle. This means you’ll start taking injectable medications needed to enable your ovaries to produce multiple eggs. We have loads of materials that can help you successfully manage this.

After close monitoring, when the time is right, you’ll be scheduled for the egg retrieval. During this 30-minute process, the doctor will remove the eggs with the aid of vaginal ultrasound while you’re under light anesthesia.

Free storage

Then, right away, your half of the eggs will be frozen. As a Split member, this whole process will be entirely free, including up to ten years of storage. In the case of an odd number of eggs, the extra one will be slated for use by the intended parents. However, any non-mature eggs retrieved will be frozen for you, since we don’t know what kind of medical advancements might take place over the next ten years. 

As a Split member, if you feel that it would be beneficial for you down the line, you can always consider doing another cycle. This will allow you to add to what you already have in storage and reap the benefits of additional free egg freezing, making the most of the program.

Adding it up

Our Split program puts egg freezing in reach for all members. It removes what’s often the biggest obstacle to taking charge of your fertility timeline — cost — while allowing an opportunity to help another family. 

Once you’ve completed the Split program, you can walk away knowing that not only have you figured out a way to make your goal of storing eggs a reality without the need for scrimping in other areas, but you’ve also succeeded in giving another family a golden opportunity they wouldn’t have had otherwise.

Our goal at Cofertility is to match intended parents with Split members who can help them achieve their goal of parenthood.  Because of that, we want to make sure we’re upfront about what might disqualify someone from our Split program. 

Through this program, you can freeze your eggs for free if you donate half to a family who can’t otherwise conceive. But, importantly, several factors may limit your eligibility.  Some of these are official disqualifiers based on regulations by the Food and Drug Administration (FDA). Others are discretionary disqualifications based on recommendations by governing bodies like the American Society for Reproductive Medicine (ASRM). 

While it’s not possible to create an exhaustive list of every reason someone may not qualify for our Split program, this guide outlines some of the most common reasons for disqualification.

Age

To apply to be a part of the Split Program, you must be between the ages of 21-33. This is because you’ll need to complete your retrieval before you turn 35, so because the process can take some time, we don’t accept applicants who are 34 or older. 

The reason for this age limitation is because data shows that, on average, those over 35 tend not to respond to fertility medication as well and therefore may not produce as many eggs. Also, research shows that, unfortunately, egg quality declines with age. Various factors may affect your cycle timing (application paperwork, time to match with a family, and more) and you will need to cycle before you turn 35. We’d hate for someone to apply, get accepted, and then when the time comes for the cycle itself, potentially age out.

If you are 34-39, you are still eligible to participate in our Keep program. With this program, you can freeze your eggs and keep 100% of them for yourself. 

If you are under 21 and you’d like to participate, please reach out and we’ll get back in touch after you turn 21. 

Health-related factors 

As a preliminary step in the process, we’ll review several health-related factors. 

For starters, you’ll need to have two ovaries and you cannot have taken a Depo Provera shot, which can interfere with hormonal medications, within the past 6 months. 

Due to these hormonal medications you’ll need to take during egg freezing, you also cannot be currently pregnant or breastfeeding. However, if you plan to stop breastfeeding within the next six months, you can still go through with your Split application. You’d just need to hold off on your actual freezing cycle until then, and this situation would be communicated to potential match families. 

Additionally, you’ll need to have a BMI of 18-29. Those outside of this range are at increased risk of complications, negative outcomes, and negative side effects from hormonal medications or an egg retrieval. 

You will not qualify if you’ve had a sexually transmitted disease within the past 12 months (but can apply after 12 months of treatment). You also will be disqualified if you’ve been refused as a blood donor due to other infectious disease or medical conditions. Same goes if you’ve ever had a blood transfusion. 

Medical and family history

We will also review your and your family’s medical history. Unfortunately, this means that if you are adopted and cannot confirm your biological family’s medical history, you will not qualify. 

Though not an exhaustive list of every condition that may disqualify a member, when reviewing your personal and family medical history, we look for personal and/or family history of:

• Cancer
• Heart/blood disease
• Neurological diseases
• Mental health disorders
• Thyroid disorders
• Genetic disease
• Fertility issues
• Reproductive disease
• Autoimmune disease
• Respiratory disease
• Metabolic disease
• Gastrointestinal disease
• Kidney disease
• Birth defects

We review your personal and family medical history as a whole with our medical advisors. When reviewing, we consider the severity of the disease/conditions, number of relatives with the disease/condition, age of diagnosis, as well as that relative’s relation to you.

Psychological screening

There are also some psychological questions you’ll have to answer. We don’t expect you to be perfect. But note that certain psychological factors may be more likely to disqualify you than others. 

For example, a history of physical, sexual or substance abuse or having family members with psychiatric disorders that could be passed down may make it more difficult to be approved than, for example, having had some mild depression or anxiety. Per ASRM guidance, we will exclude those with a personal or first-degree (parents, siblings, offspring) family history of: 

• Bipolar disorder
• Schizophrenia
• Schizoaffective disorder
• Severe depression
• History of alcoholism or drug abuse

Genetic screening

As part of the process, you’ll also be required to do genetic testing via blood test or saliva sample. This helps ensure that embryos resulting from your eggs will lead to a viable pregnancy and that a child won't be born with severe disease. 

But even for serious diseases, not all disease-related genes are deal breakers. For example, if we find that you have a copy of a gene that can lead to cystic fibrosis, spinal muscular atrophy, or thalassemia, this may or may not disqualify you; it can depend on the clinic and genes of the intended parents. 

In line with ASRM guidance, in most conditions where carrying one copy of a particular gene won't impact the child themselves, you can still qualify for the Split program. 

Physical screening

In addition to genetic screening, you will have to undergo a physical screening to ensure you are physically healthy and producing a good number of eggs.  

Some disqualifications here are set in stone by the Food and Drug Administration (FDA). If evidence of any of these conditions arises, you will be considered ineligible for the program. These are considered to be non-negotiable.

• HIV
• Hepatitis B
• Hepatitis C
• Human transmissible spongiform encephalopathy
• Treponema pallidum

The following could also be deal breakers: 

• Issues with your ovaries, such as having only one ovary
• Hormone levels outside of recommended limits with concerns about your ability to produce sufficient eggs
• Any issues that would make the egg freezing and donation process risky for your health
• Evidence that you are at high risk of getting a sexually transmitted disease or could already have one. Doctors will look for discharge or ulcerative lesions for this purpose
• Indicators of possible drug use (needle tracks, for example) or exposure to needles in non-sterile conditions—including recent piercings or tattoos within the past 12 months

Anti-Mullerian hormone (ovarian reserve) levels

As you likely know, women have a set egg quantity present at birth. Your eggs mature in ovarian follicles, and each of these follicles produces the anti-Mullerian hormone (AMH). Over time, this hormone level drops; eventually, it drops so low that women naturally develop what's known as a diminished ovarian reserve (DOR).

Your AMH level can help predict how well medication may work to stimulate your ovaries to produce eggs. It also tells doctors what dosage of drugs may be needed to do so. The higher the AMH level, the more eggs generally produced. 

At Cofertility, if your AMH < 2, you are ineligible for our Split program. We only accept Split Members with these higher AMH levels as it helps mitigate the possibility of a second cycle to obtain enough eggs that could result in a live birth down the line (for yourself and for intended parents). Nevertheless, it’s important to note that, even with a high AMH level, there is always a chance that you need to do another cycle to improve the odds of a live birth. In the Split Program, you will receive AMH-reading bloodwork prior to being activated on our platform. 

If it turns out that your AMH levels are below the required minimum threshold, you would unfortunately be ineligible to move forward with egg donation. However, we can still help you freeze your eggs for your own future use through our Keep program.

State-specific qualifications

Some states do maintain their own requirements for women who are donating eggs. These requirements will extend to those in our Split program and would be determined by the location of the clinic at which you would be conducting the retrieval. 

Any state-specific egg donation qualifications will be evaluated at the time of your physical examination. 

Additional disqualifying factors

Lastly, there are a few additional factors that, unfortunately, would disqualify you from our Split program. These include if you:

• Have served jail time for more than two days within the previous 12 months
• Have undergone body piercing and/or tattooing within the past twelve months in which sterile procedures may not have been used
• Have the highest education level of GED
• Have Indigenous American ancestry and are associated with a tribe — this is due to the Indian Welfare Act 
• Currently use any nicotine products regularly, since the ASRM has confirmed an association between smoking and decreased fertility — if you engage in vaping, you will need to quit for 2-3 months before re-applying for Split, but if you only vape occasionally/socially, you will need to quit for one month prior to your retrieval date

If one or more of the above applies to you and you’d still like to participate in our Split program, reach out to us. We’d be happy to chat with you about your fertility options, including your ability to re-apply in the future. 

The net net

We know this sounds like a lot, but these disqualifiers are in place to respect the health and wellbeing of our Split members and intended parents. If you have any questions about Split—including the factors outlined here—don’t hesitate to connect with us. 

You have tons to offer, and whether you qualify for the Split program is in no way reflective of your value. The most important thing is that you feel one hundred percent comfortable in any decision you make. This is a big one, and we’re with you every step of the way.

Egg donor agencies are all about matching families with qualified egg donor candidates. And at Cofertility, we want to make sure we’re upfront about what might disqualify someone from egg donation. 

Through our Split program, if you qualify, you can freeze your eggs for free if you donate half of the eggs to a family who can’t otherwise conceive. But some factors may limit eligibility (for Split and egg donation in general). Some of these are official disqualifiers based on regulations by the FDA. Others are discretionary disqualifications based on recommendations by governing bodies like the American Society for Reproductive Medicine (ASRM).  Read on to get the full picture.

Age

Unfortunately, most doctors and agencies will turn a donor away if she’s over age 33. At Cofertility, we take a similar approach for our Split program. 

The reason for this age limitation is because data shows that, on average, those over 33 tend not to respond to fertility medication as well and therefore may not produce as many eggs. Also, research shows that, unfortunately, egg quality declines with age. 

If you are 34-39, you are still eligible to participate in our Keep program, where you can freeze your eggs and keep 100% of them for yourself. Also, if you are over 33 and donating for a family member or friend, a doctor may approve you for egg donation on a case-by-case basis. 

Please note, per ASRM guidelines, we also do not accept Split members who are under 21. If you’re younger than this and you’d like to participate, please reach out and we’ll get back in touch after you turn 21. 

Health-related factors 

As a preliminary step in the process, we will review several health-related factors before you can be approved for egg donation. 

For starters, you’ll need to have two ovaries and you cannot have taken a Depo Provera shot, which can interfere with hormonal medications, within the past 6 months. 

Due to these hormonal medications you’ll need to take during egg freezing, you also cannot be currently pregnant or breastfeeding. However, if you plan to stop breastfeeding within the next six months, you can still go through with your Split application. You’d just need to hold off on your actual freezing cycle until then, and this situation would be communicated to potential match families. 

Additionally, you’ll need to have a BMI of 18-29. Those outside of this range are at increased risk of complications, negative outcomes, and negative side effects from hormonal medications or an egg retrieval. 

You will not qualify if you’ve had a sexually transmitted disease within the past 12 months (but can apply after 12 months of treatment). You also will be disqualified if you’ve been refused as a blood donor due to other infectious disease or medical conditions. Same goes if you’ve ever had a blood transfusion. 

Medical and family history

Agencies will also review your and your family’s medical history. Unfortunately, this means that if you are adopted and cannot confirm your biological family’s medical history, you will not qualify. 

Though not an exhaustive list of every condition that may disqualify a member, when reviewing your personal and family medical history, agencies look for personal and/or family history of:

• Cancer
• Heart/blood disease
• Neurological diseases 
• Mental health disorders
• Genetic disease
• Fertility issues
• Reproductive disease
• Autoimmune disease
• Respiratory disease
• Metabolic disease
• Gastrointestinal disease
• Kidney disease
• Birth defects

We review your personal and family medical history as a whole with our medical advisors. When reviewing, we consider the severity of the disease/conditions, number of relatives with the disease/condition, age of diagnosis, as well as that relative’s relation to you.

Psychological screening

Following this, there will be some psychological questions you’ll have to answer. We don’t expect you to be perfect. But some psychological factors may be more likely to disqualify you than others. 

For example, a history of physical, sexual or substance abuse or having family members with psychiatric disorders that could be passed down, may make it more difficult to be approved than, for example, having had some mild depression or anxiety. Per ASRM guidance, agencies - including our own - will, however, exclude those with a personal or first-degree (parents, siblings, offspring) family history of: 

• Bipolar disorder
• Schizophrenia
• Schizoaffective disorder
• Severe depression
• History of alcoholism or drug abuse

Physical screening

In addition to genetic screening, you will have to undergo a physical screening to ensure you are physically healthy and producing a good number of eggs. 

Some disqualifications are set in stone by the Food and Drug Administration (FDA). They, understandably, want to ensure that egg donor tissue doesn't spread contagious diseases. If evidence of any of these conditions arises, you will be considered ineligible for the Split program. These are considered to be non-negotiable: 

• HIV
• Hepatitis B
• Hepatitis C
• Human transmissible spongiform encephalopathy
• Treponema pallidum

The following could also be deal breakers: 

• Issues with your ovaries, such as only having one ovary
• Hormone levels outside of recommended limits with concerns about your ability to produce sufficient eggs
• Any issues that would make the egg freezing and donation process risky for your health
• Evidence that you are at high risk of getting a sexually transmitted disease or could already have one. Doctors will look for discharge or ulcerative lesions for this purpose
• Indicators of possible drug use (needle tracks, for example) or exposure to needles in non-sterile conditions—including recent piercings or tattoos within the past 12 months

Anti-Mullerian hormone (ovarian reserve) levels

As you likely know, women have a set egg quantity present at birth. Your eggs mature in ovarian follicles, and each of these follicles produces the anti-Mullerian hormone (AMH). Over time, this hormone level drops, and eventually, women naturally develop what's known as a diminished ovarian reserve (DOR).

Your AMH level can help predict how well medication may work to stimulate your ovaries to produce eggs. It also tells doctors what dosage of drugs may be needed to do so. The higher the AMH level, the more eggs generally produced. 

At Cofertility, if you appear to have low ovarian reserve at the time of screening, you will be ineligible for our Split program. We only accept Split Members with a higher AMH level as it helps mitigate the possibility of a second cycle to obtain enough eggs that could result in a live birth down the line (for yourself and for intended parents). Nevertheless, it is important to note that, even with high AMH levels, there is always a chance of having to do another cycle to improve the odds of a live birth. In the Split Program, once you are matched with intended parents, you’ll undergo your physical screening, which will include AMH-reading bloodwork. 

If you’d rather get a sense of your AMH ahead of matching, talk to us about helping you set up an initial egg freezing consultation at a local fertility clinic. While it’s not required until this later phase of the screening process, it can help you better understand your fertility outlook. We may offer discounted consult options in your area, and this could give you upfront peace of mind about your choice to pursue Split, Keep, or neither.  

Genetic screening

As part of the evaluation process, you will also be required to do genetic testing via blood test or saliva sample. This helps ensure that embryos resulting from your eggs will lead to a viable pregnancy and that a child won't be born with severe disease. 

But even for serious diseases, not all disease-related genes are deal breakers. For example, if your tests reveal that you have a copy of a gene that can lead to cystic fibrosis, spinal muscular atrophy, or thalassemia, this may disqualify you depending on the clinic. Even if two copies of the gene are needed in order for the condition to occur, clinics and agencies handle this differently.

In line with ASRM guidance, in most cases where carrying one copy of a particular gene won't impact the child themselves, you can still donate. 

Agencies often screen for Fragile X syndrome. However, since this is an X-linked condition, just one copy of the gene can cause health issues. While most agencies will disqualify you if the X-linked health issues are severe, they may allow you to participate if you carry genes for milder conditions, such as red-green color blindness. Note that agencies will still inform potential parents that you carry this gene. 

State-specific qualifications

Some states do maintain their own specific requirements for women who are donating eggs. These requirements will extend to those in our Split program and would be determined by the location of the clinic at which you would be conducting the retrieval. 

Any state-specific egg donation qualifications will be evaluated at the time of your physical examination. 

Additional disqualifying factors

In addition to the above, there are several factors that, unfortunately, would disqualify you from our Split program (and in many cases, per ASRM and/or FDA guidance, egg donation in general). These include if you:

• Are not a U.S. citizen
• Have served jail time for more than two days
• Have undergone body piercing and/or tattooing within the past twelve months in which sterile procedures may not have been used
• Have the highest education level of GED
• Have Indigenous American ancestry and are associated with a tribe—this is due to the Indian Welfare Act 

If one or more of the above applies to you and you’d still like to participate in our Split program, reach out to us. We’d be happy to chat with you about your fertility options, including your ability to re-apply in the future.

There's something about trying to get pregnant that seems to bring out the worst advice from your friends and family. Sure, they mean well, but when your cousins are swearing up and down that they know absolutely the only thing that will help you conceive, it can be hard to tell truth from fact.  

Take the myth that checking your cervical position will help you pinpoint just when you're ovulating so you can rush to the bedroom for some good old-fashioned babymaking sex. Yes, we said it's a myth.  

Although it's widely touted by some women as "the thing" that helped them tell just when they're ovulating, the fact is the only time the cervix goes through major changes is when a woman's giving birth, says Alyssa Dweck, M.D., an OB/GYN and author of The A to Z for Your Vag. Not to mention, "most women can't even feel their cervix" to determine its position, she says, so if it were to change, it would hardly help folks determine where they are in their menstrual cycle.  

If tracking my cervix won't help, how can I tell when I'm ovulating?

Forget what your cousins, best friends, and that overbearing lady at the supermarket swear will help you tell when it's time to have sex. Here are some bona fide ways actual doctors say you can tell if you're ovulating:

• Cervical mucus changes: Although the cervix doesn't move, it does produce a discharge during ovulation that can be a clear sign that you're at your most fertile, says David Diaz, MD, a reproductive endocrinologist at MemorialCare Orange Coast Medical Center in Fountain Valley, Calif. If you insert a few fingers in your vagina, and they come out with a clear, slippery, stretchy mucus on the tips, it's a good indication you're ovulating.  
• PMS-like symptoms: It doesn't sound quite fair, does it? Double the PMS? For some women, symptoms such as breast tenderness or bloating that many associate with the days before their period arrives may actually show up even earlier…when they're ovulating. The good side of this? If this is you, it may help you get a handle on your cycle.
• Cycle-tracking apps: Technology has come a long, long way in recent years, and many of the cycle-tracking apps on the market may help a woman pinpoint her most fertile period, Dweck says. Not all apps are created equal, so it's best to talk to your provider about your cycle and needs (or check out our guide here) to find out if there is an app they recommend you use.  
• Follicle ultrasounds: Cycles vary. Your best friend might have a 28-day-cycle, while yours might be more like 34 days…or maybe 21. If you haven't been able to nail that ovulation window at home, a reproductive endocrinologist may be able to help using ultrasound technology.    

The net-net

You can skip the cervix checks (and you might want to stop taking medical advice from your cousin). But there are plenty of other methods that may help you figure out the perfect time to schedule some baby-making sex sessions. Good luck!

In today's world, we crave convenience and control in every aspect of our lives, and our reproductive health is no exception. Thanks to at-home fertility testing, gone are the days of waiting for doctor's appointments and lab results to gain insights into our reproductive health. Thanks to advancements in medical technology, we now have the power to test our fertility hormone levels from the comfort of our own homes. 

At-home fertility testing has emerged as a game-changer, offering convenience, privacy, and valuable information to those who want to take charge of their reproductive journey. In this article, we will delve into the fascinating world of at-home fertility testing, exploring its benefits, the top tests available, and why testing your fertility before considering options like egg freezing is crucial.

What is fertility testing?

When you hear “fertility testing,” this generally refers to tests that help indicate your ovarian reserve. As we age, our fertility naturally declines. This is totally normal, and due to fewer eggs in the ovaries, a decrease in egg quality, and an increase in chromosomal abnormalities of the remaining eggs. These collective factors contribute to lower pregnancy rates and higher miscarriage rates as we approach age 40.

While the decline in fertility happens to ALL of us, the specific age when we can no longer conceive varies from individual to individual. And in some cases, it may be earlier than we expected.

To assess your fertility potential, including your ovarian reserve, several tests are available that can give us clues to our reproductive capabilities. These tests can also help fertility doctors evaluate the likelihood of a successful pregnancy, and guide you in making informed decisions regarding family planning and fertility treatments.

Ovarian reserve testing is just one type of fertility testing. A full fertility assessment involves assessing various aspects of reproductive health to determine your fertility potential. These tests help identify any underlying issues that may affect fertility and guide individuals in making informed decisions about their reproductive choices. 

Should I test my fertility before egg freezing?

Absolutely. Before freezing your eggs, you will undergo a battery of tests to evaluate your ovarian reserve, hormone levels, and overall reproductive health. This can help you make informed decisions about the optimal timing for the procedure, setting realistic expectations, and maximizing the chances of successful outcomes.

By undergoing fertility testing before egg freezing, you gain insights into your ovarian reserve, which refers to the quantity of eggs remaining in your ovaries. Ovarian reserve testing typically involves measuring hormones such as Anti-Müllerian Hormone (AMH) and Follicle-Stimulating Hormone (FSH). These hormones play a pivotal role in follicle development and the maturation of eggs within the ovaries. Understanding your ovarian reserve gives you a realistic understanding of your reproductive potential and helps determine the optimal timing for egg freezing. In fact, your hormones (including AMH) are correlated with egg retrieval outcomes, even more so than your age. 

Fertility testing before egg freezing also allows you to identify any underlying reproductive health issues that may affect the success of the procedure. For example, testing can reveal conditions such as polycystic ovary syndrome (PCOS) or hormonal imbalances that may impact ovulation. By addressing these issues before undergoing egg freezing, you can maximize the chances of successful egg retrieval and future fertility treatments.

Choosing the right at-home fertility test

When it comes to at-home fertility testing, you’ll want to find the right test that meets your specific needs and provides accurate and reliable results. Here are some factors to consider when selecting an at-home fertility test:

Hormones measured

Different at-home fertility tests measure varying combinations of hormones. Consider which hormones are most relevant to your fertility concerns. Commonly tested hormones include Anti-Müllerian Hormone (AMH), Follicle-Stimulating Hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and thyroid-stimulating hormone (TSH). Understanding which hormones are included in the test can help you assess if it aligns with your fertility goals.

Testing method 

At-home fertility tests utilize different testing methods, such as urine-based tests or blood spot tests. Consider your preference and comfort level with the testing method. Urine-based tests are convenient and non-invasive, while blood spot tests require a small finger prick for blood sample collection. Choose the method that suits you best.

Accuracy and reliability

Look for at-home fertility tests that have been validated and proven to provide accurate and reliable results. Read customer reviews and check for any certifications or endorsements from reputable organizations. Accuracy is crucial when making important decisions about your fertility, so opt for tests that have a track record of producing reliable results.

Cost 

Consider the cost of the at-home fertility test. Prices may vary depending on the brand and the number of hormones tested. Determine your budget and compare the prices of different tests to find one that offers good value for money. Keep in mind that fertility testing is an investment in your reproductive health and future, so prioritize quality and accuracy over cost alone.

Bonus features

Some at-home fertility tests offer additional features or services that can enhance your testing experience. For example, some tests provide personalized reports with detailed explanations of your results and recommendations. Others may offer access to fertility experts or provide educational resources to help you understand your fertility better. Consider these additional features and, if you think you’ll use them, choose a test that aligns with your preferences and needs.

What can an at-home fertility test tell me?

Fertility tests are powerful tools that provide valuable insights into your reproductive health and potential. They offer a comprehensive assessment of various aspects of your fertility, allowing you to understand your body's unique dynamics and make informed decisions about your reproductive future. 

Ovarian reserve testing measures the quantity of eggs remaining in your ovaries. In particular, hormone tests that examine your AMH and FSH levels provide information about the quantity of eggs available for fertilization. These tests can give you an indication of your ovarian reserve and help determine the optimal timing for egg freezing, fertility treatments, and family planning options.

Fertility tests assess the levels of various hormones involved in reproductive health. Abnormal hormone levels can indicate something that may affect your fertility down the line. For example, conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can impact fertility and require targeted treatment. By identifying any issues early on, you and your healthcare provider can proactively tackle any underlying issues.

Keep in mind that fertility tests provide a snapshot of your reproductive health at a specific point in time. They offer valuable information but do not guarantee future fertility or pregnancy outcomes. You’ll want to discuss the results of your fertility tests with your doctor who can interpret the findings in the context of your individual circumstances.

What *can’t* an at-home fertility test tell me?

While fertility tests can provide valuable insights into your reproductive health, it's important to understand their limitations. 

One of the common misconceptions is that fertility tests, particularly AMH, can predict your chances of getting pregnant unassisted. In fact, studies have shown that AMH is not related to time to pregnancy. 

Fertility tests cannot provide a definitive prediction of your ability to conceive without assistance. Beyond just ovarian reserve, fertility is a complex interplay of various factors, including egg quality, sperm quality, uterine health, and overall reproductive function. The test results can give you an indication of your ovarian reserve and potential response to egg freezing or IVF, but they cannot guarantee unassisted conception.

Fertility tests provide insights into your current fertility status but cannot predict your fertility potential in the future. Your reproductive health will change over time due to various factors, including age, lifestyle choices, and underlying medical conditions. So even if your fertility test results are within the normal range, it does not guarantee that your fertility will remain the same in the future. Regular monitoring and discussions with your healthcare provider are essential to track any changes in your fertility health over time.

Understanding the limitations of fertility tests can help manage expectations and help you make informed decisions. It's important to view these tests as tools to assess certain aspects of your fertility health, but not as definitive predictors of your reproductive journey. Consulting with a fertility doctor can help you interpret the test results in the context of your individual circumstances and guide you through the next steps in your fertility journey.

Summing it up

By understanding what fertility tests can and can’t tell you, you gain valuable knowledge about your reproductive health and fertility potential. This knowledge empowers you to make informed decisions about family planning, seek appropriate medical intervention if necessary, and take proactive steps to optimize your fertility. Fertility tests are a vital tool in the journey towards building the family you desire, providing valuable insights that can guide you on the path to reproductive success.

However, it's important to remember that fertility tests have their limitations. They provide a snapshot of your fertility health at a specific point in time and cannot guarantee future outcomes. It's crucial to interpret the test results in the context of your individual circumstances and consult with a fertility doctor for a comprehensive evaluation of your reproductive health.

Ultimately, knowledge is power, and by understanding your fertility health, you are better equipped to make decisions that align with your personal goals and aspirations. Embrace the opportunities offered by at-home fertility testing, stay informed, and engage with fertility doctors who can provide guidance and support throughout your reproductive journey. With the right information and support, you can take charge of your fertility and empower yourself.

If you are interested in freezing your eggs, we can help! Our Freeze by Co platform is making egg freezing more empowering, positive, and accessible — even free — when you give half of the eggs retrieved to a family who can’t otherwise conceive.

I was 28 when I first started trying to conceive. I vividly remember taking my last birth control pill, throwing out my pack, and texting my friend to tell her we were no longer “not trying,” excited but nervous. Sounds pretty standard, right? Unfortunately, what I didn’t know at the time was that I was about to embark on a two-and-a-half-year journey to get pregnant with my son. This included several pregnancy losses, a few rounds of IVF, and lots of questions, including, “should I have tested my fertility sooner?”. 

I don’t share this to scare anyone. But my story is not all that uncommon. In fact, 1 in 6 individuals experience some form of fertility challenge. 

I was woefully unprepared. And because of this lack of preparedness by Sex Ed as well as limited time with my OBGYN, it probably took a good six months before I started to understand what actually goes into conceiving a healthy pregnancy: timing, lifestyle, genetics, and more. So much of my time, stress, and probably money could have been saved by proactive fertility testing.

In this article, we’ll discuss when to test your fertility, the importance of early fertility awareness, and proactive measures you can take to understand it. If you take one thing away from this article, though — the best time to test your fertility is right now. Let’s talk about why. 

So what is fertility testing, anyway?

Before we dive into when to test your fertility, it’s important to understand what fertility testing even is. 

Ovarian reserve testing

A fundamental concept of assessing one’s fertility is to understand their ovarian reserve. This involves evaluating the quantity of a woman's remaining egg supply (oocytes) in her ovaries. One of the most widely used tests for ovarian reserve (though not without its limitations — more on that below) is the measurement of Anti-Mullerian Hormone (AMH) levels, which can be done with a simple blood test. 

Understanding AMH

AMH is a protein produced by cells in the ovarian follicles, with levels of AMH in your blood providing an indication of the number of eggs remaining in your ovaries. If you’re considering egg freezing, AMH testing is especially valuable, as it helps assess your starting point and may indicate a timeline of how urgently you may want to move forward with freezing your eggs. 

Your AMH may also give a sense of how your ovaries might respond to the actual egg freezing process. Lower AMH levels typically suggest a diminished ovarian reserve, which may impact fertility potential. In general, an AMH between 1.0 - 3.5 ng/mL is considered a “normal” range. 

Individuals with a higher AMH level — which varies by lab, but could be anywhere over 3.0 ng/ml — usually have a better response to ovarian stimulation, leading to a higher number of eggs likely to be retrieved during the procedure. That said, a higher AMH also carries a greater risk of ovarian hyperstimulation syndrome (OHSS), so your doctor will need to be careful with your medication protocol and monitoring.

Should I test my fertility at home or in a clinic?

At-home fertility tests have gained popularity in recent years due to their convenience and privacy. These tests typically involve collecting blood or urine samples and mailing them to a laboratory for analysis. On the other hand, in-clinic fertility tests are conducted at a medical facility, where specialized equipment and healthcare professionals are available.

The pros of at-home fertility tests

• Convenience and privacy: Samples can be collected in the comfort of your home.
• Cost-effective: At-home tests are often more affordable than in-clinic procedures.
• Early assessment: At-home tests allow you to gain insights into your fertility potential before actively trying to conceive. Plus, you won’t have to wait to get squeezed in for an appointment at the clinic!

The pros of testing your fertility at a clinic

• A broader scope: At-home tests may not provide a comprehensive evaluation of fertility health, while testing your fertility at a clinic provides a more comprehensive picture of your fertility. An important note is, when testing your fertility at a clinic, you’ll also undergo a transvaginal ultrasound, where the technician or doctor will be able to get a view of what’s going on in those ovaries and the number of follicles available this cycle.
• Better accuracy: Some at-home tests may have varying levels of accuracy when compared to in-clinic tests.
• Face time: At a clinic, you’ll have the ability to chat directly with a doctor, before and after your results.

When should I test my fertility? 

So, when is the “right” age for testing your fertility, anyway? 

It depends.

And ultimately, it’s up to you! It’s your body, and your data, and there is no one-size-fits-all answer. We’re firm believers that knowledge is power and you deserve this information. Studies do show that our ovarian reserve declines with age — in other words, it’s a good idea to assess your fertility potential sooner rather than later. That way, if you do want to preventatively freeze your eggs, you can do so while your ovarian reserve is still higher. 

According to the American Society for Reproductive Medicine (ASRM), the optimal time to freeze your eggs is in your 20s and early 30s. And this study indicated that, as we get older, our chances increase of needing to do multiple egg freezing cycles in order to achieve a 70% live birth rate. We know we’re a bit of a broken record here, but: the younger you are, the healthier and more plentiful your eggs are. 

Consider your egg freezing plans

Because the ASRM doesn’t recommend egg freezing for people older than 38 (although this is not a hard and fast rule), it’s a good idea to test your fertility earlier on if possible. That way, should you decide to move forward with egg freezing, you’ll have the time and space to come up with a plan and hopefully see some successful results.

If and when you decide to move forward with egg freezing, you can freeze your eggs more affordably (even for free!) with Cofertility. Fill out this quick quiz to learn about our accessible egg freezing options and see if you qualify for our programs — it only takes one minute.

Should I test my fertility in my 20s?

Testing your fertility in your 20s gives you the most flexibility. Whether your testing looks great and you want to freeze your eggs now, or you uncover potential fertility risks to address, the more time you have, the better. 

Your doctor may even recommend fertility testing if you have past or current reproductive health issues, including sexually transmitted infections (STIs), endometriosis, or PCOS, all of which can contribute to fertility challenges. Even if you’re not yet sure if you want to start a family in the future, testing your fertility in your 20s may help you make informed decisions about family planning options down the line. 

Best at-home fertility tests

If you’re curious to learn more about your ovarian reserve, talk to your doctor about fertility testing. If your doctor won’t order the tests…you might want to find a new one who listens to your concerns and takes them seriously. But in the meantime, there are many great at-home fertility testing options out there.

Remember: at-home fertility tests aren’t without limitations

Although at-home fertility tests are a great way to get a peek behind the curtain of your fertility, they aren’t without limitations. For starters, according to recent studies, measuring AMH alone may not predict your time to pregnancy. As mentioned above, testing your fertility with a doctor at a clinic will likely provide a more comprehensive picture of your fertility outlook, especially as they consider your medical history, and conduct a physical exam and transvaginal ultrasound. Of course, you’ll also get professional interpretation of the results that you may not receive with an at-home fertility test. 

All of that being said, any fertility testing (whether at home or in a clinic) only measures your fertility at that given point in time. It should not be taken as a guarantee for future outcomes. It also can’t tell you anything about your egg quality, which cannot be truly observed until it comes time to actually fertilize those eggs. 

Consider egg freezing as a proactive measure

After testing your ovarian reserve, it’s worth considering freezing your eggs if you don’t want kids soon. We’ll be the first to say that egg freezing is not a guarantee for a successful pregnancy in the future — those eggs need to be fertilized into embryos, transferred to a uterus, and then carried for 40 weeks to result in a live birth! But because our fertility declines with age, the earlier we preserve it, the more set up for success we may be in the future if we do need to use those eggs down the line. 

How does egg freezing work? 

As a primer, egg freezing allows individuals to preserve their fertility by freezing and storing their eggs for future use (fertilization). Let’s get into some of the specifics. 

Some benefits of egg freezing

There are many reasons why egg freezing can be beneficial, including: 

Delaying parenthood: Egg freezing enables individuals to postpone childbearing to pursue educational, career, or personal goals while increasing their chances of having a healthy pregnancy down the line.

Medical reasons: Some medical treatments, such as chemotherapy or radiation, can impact fertility. Egg freezing offers a proactive option for individuals facing medical conditions that may affect their reproductive health.

Preserve higher quality eggs: As we age, our ovarian reserve diminishes, and the quality of our eggs declines. By freezing eggs at a younger age, individuals can preserve their eggs when they are of higher quality.

The egg freezing process

Overall, the egg freezing process is a 10-14 day period involving ovarian stimulation, the actual egg retrieval, and storing the frozen eggs. Here’s what goes into each.

Ovarian stimulation: Before the egg retrieval, individuals typically take injectable hormone medications for about 10-14 days. This process encourages the ovaries to produce multiple mature eggs. You’ll head to the clinic for monitoring every few days (more frequently as you get closer to your retrieval) so your doctor can check on how things are progressing and make updates to your medication protocol if needed.

The egg retrieval: Once the eggs are mature, a minimally invasive procedure known as transvaginal ultrasound-guided aspiration is performed to retrieve the eggs from the ovaries. The procedure is usually well-tolerated and does not require a surgical incision.

Cryopreservation: After retrieval, the eggs are frozen using a process called vitrification. This method prevents the formation of ice crystals, which could damage the eggs during freezing. You’ll store your eggs in a special storage facility meant for just that.

Success rates of egg freezing

The success of egg freezing largely depends on the age at which the eggs are frozen. Generally, eggs frozen at a younger age have a higher chance of resulting in a successful pregnancy. Advanced vitrification techniques have significantly improved egg freezing success rates, with some studies reporting comparable pregnancy rates between fresh and frozen-thawed eggs.

One study of 1,241 women found that the average number of eggs retrieved on the first egg freezing round was:

• 21 eggs for women under 35
• 17 eggs for women 35-37
• 14 eggs for women 38-40

But, in addition to egg quantity, we also need to consider egg thaw survival rate, and the rate at which these eggs become embryos and result in a live birth. According to a study in the Journal of Assisted Reproduction and Genetics, a woman under 35 will need 9 eggs to achieve a 70% chance of having at least one live birth. If you’re trying to conceive in your mid to late 30s, you may need double as many eggs to achieve that same 70% success rate. 

Not only will freezing your eggs proactively give you the options of utilizing higher quality eggs in the future, it also helps alleviate the pressure of finding a reproductive partner, and can allow us to feel empowered to make family planning decisions on our own terms without any compromises. Taking a proactive approach to fertility preservation can provide the freedom to pursue opportunities without sacrificing the dream of having a family when the time is right.

Freezing your eggs with Cofertility

With Freeze by Co, you have the opportunity to apply to our Split program, where you can freeze your eggs for free when you donate half of the retrieved eggs to a family that can’t otherwise conceive. The cost of the entire process, including 10 years of cryopreservation, is fully covered. 

Or, if you want to freeze and store your eggs for your own future use without donating, as part of our Keep program, we offer lower prices on things like consultations and storage, along with access to our community of others going through the process at the same time. ‍Plus, you’ll have direct access to our team, which is here to support you throughout the entire journey.

Summing it up

If you’re considering testing your fertility, the best age to do it is now. Whether you test yourself at home, or with a doctor at a fertility clinic, testing your fertility can provide valuable insights into what your family-building future may look like. It might also uncover the need for egg freezing in order to preserve some of your existing fertility as it stands today. But whatever you decide to do with the results, you’ll at least be armed with more information about yourself than you would have had otherwise. 

Are you ready to embark on a journey through the fascinating world of female fertility hormones? We've got all the details on those tiny chemical messengers that hold the key to your reproductive prowess. Whether you're curious about boosting your chances of egg freezing success or simply want to understand the inner workings of your amazing body, this article will dive into a hormonal adventure that will leave you feeling empowered and in control. Let’s go!

Anti-Mullerian Hormone (AMH)

What it is

The most talked about hormone of them all: AMH. AMH is produced by the developing follicles in the ovaries and serves as an biomarker of ovarian reserve. It helps estimate the quantity of eggs remaining in the ovaries and is commonly used in assessing how well your body will respond to IVF or egg freezing. 

Normal AMH levels

You can take an AMH test any time in your cycle. In general, AMH levels can be interpreted by:

• Above 1.0 ng/ml (nanograms per deciliter): Normal
• Below 1.0 ng/ml: Showing weakness in the ovarian reserve
• Below 0.5 ng/ml: Showing severe weakness in the ovarian reserve

Keep in mind that lab numbers can vary. Your blood test results will show the lab’s normal range on the report.

What AMH can tell you

As we age, our AMH levels naturally decrease until we hit menopause and our AMH reaches 0. While the decline in fertility happens to ALL of us, the specific age when we can no longer conceive varies from individual to individual. And in some cases, it may be earlier than expected. AMH can give us insight into where we are on that journey.

While AMH is pretty awesome, there are two things it can’t tell us: (1) it can’t tell us the quality of the eggs remaining and (2) it can’t tell us our chances of getting pregnant unassisted.

Estrogen

What it is

Estrogen hormone is the ultimate multitasker, responsible for so many amazing things. It's the power behind that glowing, radiant skin and full, thick hair. And it also takes charge of thickening the uterine lining each month, which either sets the stage for a growing embryo, or culminates in your period.

Estrogen is actually a collective term used to describe a group of hormones that play a vital role in the female reproductive system. It includes three types of hormones: 

• Estrone (E1) which is the only type of estrogen that our bodies keeps making even after menopause
• Estradiol (E2) causes the maturation and release of the egg as well as the thickening of the uterus lining each month
• Estriol (E3) is really only present during pregnancy, and helps the uterus grow and stay healthy

Estrogen levels fluctuate throughout the menstrual cycle, with estradiol being the dominant form during the follicular phase (leading up to ovulation) and progesterone taking the lead during the luteal phase (after ovulation). Understanding the dynamics and functions of estrogen and estradiol can help shed light on the intricate mechanisms underlying female reproductive health.

Altogether, estrogen plays a key role in regulating the menstrual cycle, supporting the growth and development of the uterus and breasts, and maintaining bone health.

Normal E2 levels

Estrogen levels fluctuate throughout your life, often aligning with other hormones that regulate crucial bodily functions, such as the menstrual cycle. These dynamic changes in estrogen levels are considered a normal part of the body's hormonal rhythm. 

Estradiol (E2) is the hormone most often tested for fertility. E2 levels vary widely through the menstrual cycle, and are expected to fluctuate from test to test. A normal range is considered:

• Premenopausal: 30 to 400 pg/mL (110 to 1468.4 pmol/L)
• Postmenopausal: 0 to 30 pg/mL (0 to 110 pmol/L)

There can be variations in the normal value ranges for laboratory tests, as different laboratories may use different measurement methods (e.g. saliva, blood prick, or venipuncture) or test different samples. Your doctor will be able to provide you with accurate interpretation and insights based on your individual circumstances.

What E2 can tell you

If you consistently test on the lower range, it may indicate the onset of menopause, premature ovarian failure, or low estrogen from rapid weight loss or anorexia. If your results are higher, it may suggest a tumor of the ovary.

Follicle-Stimulating Hormone (FSH)

What it is

‍FSH is the ultimate fertility cheerleader. Like the squad captain, FSH leads the charge in the growth and development of those ovarian follicles, which contain the eggs. It's the one shouting, "Let's grow those eggs, ladies!" 

Our FSH levels change throughout the menstrual cycle, with the highest levels happening just before ovulation (when an egg is released by the ovary).

Normal FSH levels

For fertility testing, you need to have the FSH blood test on day 3 of your menstrual cycle (day 1 is the day your period begins). In general, normal FSH levels are:

• Premenopausal: 4.7 to 21.5 mIU/mL
• Postmenopausal: 25.8 to 134.8 mIU/mL

Keep in mind that lab numbers can vary. Your blood test results will show the lab’s normal range on the report.  

What FSH can tell you

‍Higher-than-normal levels of FSH can be a sign of infertility due to premature ovarian failure or menopause. It could also be due to certain types of tumors in the pituitary gland, or due to Turner syndrome.

Lower levels could mean pregnancy, being very underweight or having had recent rapid weight loss, not ovulating, or that parts of the brain are not producing normal amounts of hormones. If you have abnormal results, your doctor will discuss your situation and next steps. 

Luteinizing Hormone (LH)

What it is

This hormone takes center stage and demands attention as it triggers the grand finale of the menstrual cycle: the release of a mature egg. LH sends that egg on its way, ready for its moment in the spotlight and a chance at fertilization.

While LH has a major job for our reproductive system, it’s actually secreted by a tiny structure in your brain called the pituitary gland.

Normal LH levels

LH fluctuates throughout your cycle, and the ranges are:

Premenopause: 5 to 25 IU/L

Postmenopause: 14.2 to 52.3 IU/L

Remember, lab numbers can vary. Your blood test results will show the lab’s normal range on the report.  

What LH can tell you

Abnormal LH levels can indicate ovulatory disorders, such as polycystic ovary syndrome (PCOS) or hypothalamic amenorrhea. 

LH testing (via urine test strips) can also help to predict ovulation. By detecting the LH surge each cycle, these test strips give us a glimpse into our fertile windows, or when we’re most likely to get pregnant. 

Progesterone

What it is

Progesterone swoops in after ovulation (which, remember, was ushered in by LH) to prepare the uterine lining, transforming it into a cozy, welcoming haven for a potential embryo. Progesterone is crucial for early pregnancy, helping maintain the thickened endometrium. But if an egg isn’t fertilized during that cycle, progesterone levels decrease, your uterine lining thins, and your period begins. 

Normal progesterone levels

• Pre-ovulation: less than 1 nanogram per milliliter (ng/mL) or 3.18 nanomoles per liter (nmol/L)
• Mid-cycle: 5 to 20 ng/mL or 15.90 to 63.60 nmol/L
• Postmenopausal: less than 1 ng/mL or 3.18 nmol/L
• Pregnancy 1st trimester: 11.2 to 90.0 ng/mL or 35.62 to 286.20 nmol/L
• Pregnancy 2nd trimester: 25.6 to 89.4 ng/mL or 81.41 to 284.29 nmol/L
• Pregnancy 3rd trimester: 48 to 150 to 300 or more ng/mL or 152.64 to 477 to 954 or more nmol/L

What progesterone can tell you

While LH tests can help us predict when we’re about to ovulate, progesterone tests can help confirm if we actually did ovulate. 

If you have low progesterone and aren’t pregnant, you may have symptoms like irregular periods, infertility, mood changes, trouble sleeping, or hot flashes.

If you have low progesterone and are pregnant, it could mean a higher risk of miscarriage or an ectopic pregnancy.

Prolactin

What it is

Prolactin is the hormone that orchestrates the magic of breastfeeding. It causes the breasts to grow and make milk during pregnancy and after birth. While its primary role lies in the breastfeeding realm, elevated levels of prolactin when not pregnant or postpartum can sometimes interfere with ovulation and menstrual regularity.

Normal prolactin levels

Made in the the pituitary gland, normal levels of prolactin are:

• Nonpregnant: less than 25 ng/mL (25 µg/L)
• Pregnant: 80 to 400 ng/mL (80 to 400 µg/L)

Keep in mind that lab numbers can vary. Your blood test results will show the lab’s normal range on the report. Talk to your doctor about your specific results.

What prolactin can tell you

Abnormally high levels of prolactin when you are not pregnant could mean a condition called hyperprolactinemia, which is actually quite common. Believe it or not, about a third of women in their childbearing years with irregular periods (but perfectly normal ovaries) have hyperprolactinemia. Hyperprolactinemia could mean trouble getting pregnant. Not to mention, your boobs might start producing milk when you're not even expecting it (hello, galactorrhea!).

High prolactin levels can also throw a wrench in the normal hormone production, messing with the likes of estrogen and progesterone. And when that happens, it can disrupt ovulation or lead to irregular or missed periods. 

Thyroid-Stimulating Hormone (TSH)

What it is

This hormone ensures that our thyroid gland, that tiny powerhouse in our neck, is working harmoniously. Thyroid health is crucial for maintaining menstrual regularity and fertility, so when TSH steps onto the scene, you know it's time to keep that thyroid in check!

Normal TSH levels

Another hormone produced by the pituitary gland, TSH can give us insight into thyroid disorders, such as hypothyroidism or hyperthyroidism.

• Nonpregnant: 0.27 – 4.2 uIU/mL.
• First trimester (9 to 12 weeks): 0.18 – 2.99 (uIU/mL).
• Second trimester: 0.11 – 3.98 uIU/mL.
• Third trimester: 0.48 – 4.71 uIU/mL.

What TSH can tell you

Low levels of TSH typically indicate hyperthyroidism, or overactive thyroid, when your thyroid gland is making excess thyroid hormone. On the other hand, high levels of TSH may suggest an inadequate production of thyroid hormone, leading to a condition called hypothyroidism or underactive thyroid. 

Testosterone

While testosterone is often associated with male reproductive health, females also produce small amounts of testosterone from the ovaries. It helps preserve muscle mass and supports an overall sense of wellbeing. It also helps the development of those follicles and even plays a role in boosting our libido.

Testosterone does fluctuate throughout your cycle, so if you notice that your libido surges at certain times of your cycle (usually around ovulation), you can thank testosterone.

Normal testosterone levels

15 to 70 ng/dL or 0.5 to 2.4 nmol/L

What testosterone can tell you

Abnormal testosterone levels can negatively affect fertility. 

Too little testosterone could mean you are nearing menopause or have premature ovarian failure. It could also be lower due to certain medications, malnutrition, chemotherapy/radiation, 

Too much testosterone could be a sign of PCOS.

At-home fertility hormone testing

If you’re curious to test your hormones, you'll be glad to know that there are convenient at-home options available. These tests allow you to assess your hormone levels from the comfort of your own home, providing valuable insights into your reproductive health. 

Let's take a closer look at some of the top at-home fertility hormone testing options for you to consider:

• Natalist Women’s Fertility Test: Priced at $149, this comprehensive test covers a range of essential hormones. It measures five key hormones: estradiol, LH, FSH, TSH, and total testosterone. By examining these hormone levels, you can gain a better understanding of your reproductive health. And here's a bonus for our readers: use the code COFERTILITY20 to get 20% off!
• LetsGetChecked Ovarian Reserve Test: For $139, this test specifically focuses on measuring anti-Müllerian hormone (AMH), a critical marker for ovarian reserve. By understanding your ovarian reserve, you can make informed decisions about family planning and fertility preservation. And guess what? You can save 25% on this test by using code COFERTILITY25.

These at-home fertility hormone testing options give you the opportunity to better understand your reproductive health. But keep in mind that if you are planning to freeze your eggs, your doctor may want you to test again. 

Summing it up

These fertility hormones - AMH, Estrogen, FSH, LH, Progesterone, Prolactin, and Testosterone– work in harmony to regulate the menstrual cycle, facilitate ovulation, prepare the uterus for pregnancy, and support early gestation. 

Imbalances or abnormalities in these hormone levels can affect fertility and reproductive health. Unfortunately for many of us, we don’t find out there’s a problem until we start trying. 

Evaluating the levels of these hormones through diagnostic tests can provide insights into your fertility health and empower you with knowledge to make informed decisions about your reproductive journey.

By understanding your hormone levels, you can identify potential issues that may hinder reproductive health, now or in the future.

Can you test your fertility from the comfort of your own home? The answer is a bit complicated. Isn’t it always when it comes to fertility? Yes, there are some tests that both men and women can take at home to get a better idea about some aspects of their fertility. But are they an acceptable substitute for an individualized appointment with a fertility specialist? 

Unfortunately, no—while these tests are often fairly accurate, that’s not really the issue here, says Dr. Jaime Knopman, a board-certified reproductive endocrinologist. It’s all the medical expertise you’re missing out on when you test your fertility at home. 

“The tests we run in our clinic are much more accurate because our job can’t be done completely by machine,” she explains. “It’s not just the tests, it’s the person interpreting them.”

But you still might not live close to a fertility clinic, have insurance that covers fertility appointments or testing, or even feel like you’re really at the point yet in your fertility journey where you need a formal eval from a specialist. We get that.

So whatever your reason for wanting to take an at-home fertility test, here’s what you need to know about what your options are, how they work, and what you can expect to learn.

How can I test my fertility at home: for women

When it comes to the ladies, there are two main varieties of tests you can do at home: you can check your ovarian reserve and you can do a broad panel screening for several different hormones that play a part in fertility health. Here’s the scoop.

Ovarian reserve tests measure the amount of follicle-stimulating hormone (FSH) in your blood with a pinprick. Typically, you collect a sample yourself and mail it back to the company so they can read and deliver your results. Very high levels of FSH can be a sign that you don’t have a lot of eggs, that they’re poor quality, or both, because your body is working overtime to produce enough FSH to release a healthy egg.

• Taking this test feels like a typical finger prick. It hurts for a sec and then you’re over it. You will have to squeeze out some blood into designated spots on a testing card, though, so if you’re blood-averse be prepared.
• The tests themselves can accurately check your FSH level, but there’s more than one way to figure out what your ovarian reserve looks like. Only measuring FSH will give you a piece of the puzzle...but could also cause you to unnecessarily panic about your fertility. Try not to do that! Remember, these tests are useful, but not foolproof.
• FSH levels alone may not be a great way to assess your fertility in the first place. A 2017 JAMA study found that biomarkers like FSH aren’t the best predictors of future fertility in women with reduced versus normal ovarian reserves.

Fertility health screenings capture your FSH level but also a bunch of other hormones that impact your fertility in one way or another. The exact hormones measured in an OTC fertility test differ between companies, but you can usually find out your FSH level and any or all of the following:

• thyroid-stimulating hormone, or TSH a marker of thyroid health)
• estradiol (helps with ovulation)
• anti-mullerian hormone, or AMH (an indicator of egg reserve)
• prolactin (makes breast milk after birth)
• luteinizing hormone, or LH (regulates your cycle, especially ovulation)
• testosterone (helps make follicles, but too much may mess up your fertility)

These tests all work like the ovarian reserve test: you prick your finger, collect some blood samples, send the samples back to the company, and then wait for your results to come in. Usually, you’ll get factual data (like, “your TSH is off”) but also an explanation of what that might mean for your fertility. 

Most companies allow you to see your results online and consult with an on-staff medical professional if you have questions or don’t understand your results. They’re pretty easy to order online, but many aren’t cheap—they’re usually about $150—and you’ll have to pay out of pocket.

How can I test my fertility: for men

The only kind of male fertility test that can be done at home is a sperm analysis. About half of all couples’ infertility problems can be caused by male infertility, so knowing if your swimmers are strong or not is a good place to start if you’ve been trying to conceive for a while. 

There are actually several different kinds of sperm analysis kits; sometimes you collect a sample and send it through the mail for testing, sometimes you put some sperm on a slide and insert it into a testing device, and sometimes you can even use your smartphone (yes, for real!). 

• Testing at home is private and confidential. You don’t have to worry about being unable to provide a sample at an unfamiliar clinic or doctor’s office. 
• The kits you send off to labs via mail can be more accurate, but at the same time, there’s a lot that can go wrong here—like failure to keep the sperm stored at just the right temp, which can cause damage to the sample. At-home tests, while giving quicker results with no middle-man, have a lot of potential for both user and technology errors.
• Male fertility is about more than just the amount of sperm: there’s motility, shape, concentration...the list goes on. If your at-home kit is only looking at the number of sperm, your results may not be that helpful. Try to choose a test that looks at more than one type of factor—this will give you the most bang for your buck. 

Don’t forget about ovulation!

While ovulation predictor kits only tell you if and when you’re ovulating, this can be very helpful if you’re actively TTC. 

These kits work by detecting the presence of LH in the urine, says David Diaz, MD, reproductive endocrinologist and fertility expert. When your LH rises above a certain level, the test strip you’ve peed on will let you know that an ovary is just about to release an egg. This is a good time to get it on, since there’s a good chance that egg could become fertilized. 

According to Dr. Diaz, these tests are about 85 percent accurate and available as digital and non-digital tests. If you have fairly regular menstrual cycles, an ovulation predictor kit can be a useful tool in identifying exactly when your fertile window is, but if your cycles are irregular (because of PCOS, pre-menopause, or even just your personal biology), it can be harder to rely on them unless you’re taking a test every day.

Next steps

Okay, you took an at-home test and got your results back...now what? Well, you might not like our answer, but here it is: you should probably still go see a fertility doctor. Yes, even if your results are “normal.” Why? 

Because, like we told you upfront, a test you do at home gives you important data — but not the expertise and counsel of a doctor who has met you in person and knows your medical history. You’ll have the info, just not necessarily the context...and the context is super important when it comes to your fertility. At-home tests simply can’t paint the same kind of comprehensive picture that doctor-interpreted lab tests can. 

But you’re here because you want to take an at-home fertility test...and TBH, we kinda don’t blame you! We’re curious, too! Just make sure you know what you’re buying, (Dr. Knopman says that you should make sure any OTC test you buy comes from a legit manufacturer with a fertility doctor on their medical review board), what the tests can tell you, and what you’re going to do with the results. 

“Even if you don’t want to do fertility treatments [right now], there is no harm in coming in to talk to us about it,” says Dr. Knopman. “You can make better decisions when you have that information than when you don’t…[and] the worst thing to do is sit at home and ruminate, trying to interpret your own results or diagnose yourself.”

What’s the takeaway here? After taking an at-home fertility test, you might want to plan to make an appointment with a fertility specialist. It can be a simple introductory or informational appointment, and even a virtual one. But hopefully, it will give you peace of mind and — most importantly — answers.

• Female Fertility Hormones: Everything They Didn’t Teach You in Sex Ed
• A Step-by-Step Guide to Freezing Your Eggs

Ever scrolled through that health and wellness side of social media and stumbled upon something called AMH? Maybe your best friend casually mentioned getting her AMH tested, and you were too embarrassed to ask what the heck she was talking about. You're young, you feel great, and having babies isn't even on your radar right now. But here's the thing: understanding this thing called AMH could be a major game-changer for your future.

What is AMH?

AMH stands for Anti-Müllerian Hormone.  Think of it as a little signal your ovaries send out. This hormone level tells your doctor about how many eggs you have left – also known as your ovarian reserve. Basically, AMH is one clue into your fertility.  And, here's why you should care even if kids aren't on your mind yet.

Why does AMH matter in your 20s and 30s?

AMH can be a helpful biomarker for your health and fertility. Why?

1. Knowledge is power: Knowing your AMH levels gives you valuable insights into your reproductive timeline. It helps you make informed decisions about when you might want to start a family and whether fertility preservation options (like freezing your eggs) might be something to consider down the road.
2. Fertility isn't forever: You might think of your 20s as your prime fertility years, and while you're not wrong, it's not the full picture.  Your fertility peaks in your early 20s and starts a gradual decline in your mid-30s. For some people, this decline is faster, and AMH levels can give you a heads-up.
3. Unexpected roadblocks: AMH testing can help detect potential fertility issues early on, like Polycystic Ovarian Syndrome (PCOS) or premature ovarian insufficiency. Getting this info sooner rather than later can help you take steps to manage these conditions and protect your fertility.

What can AMH test results tell you?

So what exactly can AMH tell you about your fertility? Your AMH level is positively correlated with the number of follicles you have in your ovaries. Simply put, the more follicles you have, the higher your AMH level typically is. As a result, AMH levels have been shown to be a good predictor of ovarian reserve and someone’s expected response to fertility treatments. 

In fact, several studies have shown that there is a strong correlation between what your AMH level is and the number of mature eggs retrieved during an egg freezing or in vitro fertilization (IVF) cycle. To learn more about those studies, check out AMH and Egg Retrieval Outcomes. 

What your AMH level can’t tell you is the exact number of eggs you have left in your ovaries or what your chances of pregnancy are. There are a number of other factors like your age, overall health, and genetics that also affect the number and quality of eggs and your overall fertility. So while AMH can be a useful tool in assessing your fertility, it shouldn’t be the only factor when making decisions about fertility treatments.

So, you got your AMH tested. Now what? Here's a basic breakdown of what those numbers usually mean: 

• Normal AMH means you're right on track for your age – good news!  
• High AMH might suggest a good number of eggs remaining, and potentially even point towards conditions like PCOS where your egg count is unusually high. 
• Low AMH could mean you have fewer eggs remaining than typical for your age group.  It might signal a faster decline in fertility, but it doesn't mean you can't get pregnant at all.  

Remember, your AMH level is just one piece of the fertility puzzle. Other factors like your overall health, other hormone levels, family history, and lifestyle habits matter too!

What are normal AMH numbers?

What is considered a “normal” AMH level depends on your age, as well as the lab where you take the test. Since there is no international standard, it’s best to use the reference ranges included on the test results (your doctor can share those with you if you did a test through a clinic). 

In general, however, an AMH between 1.0 and 3.5 ng/mL suggests a “normal” range that is likely to have a good response to egg freezing.

Common reasons for high AMH

The most common reason for high AMH is that you are very fertile and likely to retrieve more eggs in an egg freezing cycle.  But, it does not necessarily mean that the eggs are of good quality. Egg quality is determined by factors such as your age, genetics, and environmental factors, and cannot be measured directly by AMH levels.

But a high AMH level may also indicate PCOS, which is a hormonal disorder that affects 8–13% of females of reproductive age. Those with PCOS typically have high levels of androgens (male hormones) and may have irregular periods, acne, and excess hair growth. Patients with an average AMH level ≥ 4.45 ng/ml have a 9.35 times higher likelihood of developing PCOS, but not all patients with a high AMH have PCOS.

In rare cases, abnormally high AMH could be a sign of an ovarian tumor. Certain types of ovarian tumors, such as granulosa cell tumors, can produce high levels of AMH.

Common reasons AMH would be low

By far, the most common reason for a low AMH is age. People with ovaries are born with all the eggs that they’re going to have in their lifetime. These eggs are then slowly used up over time as you ovulate during each menstrual cycle until menopause is reached. As a result, ovarian reserve naturally decreases over time, meaning the AMH level also decreases. 

Research suggests that hormonal birth control may affect AMH levels but it depends on the type of birth control. Specifically, birth control use is associated with a lower average AMH level than for people who are not on birth control, with the exact effect depending on the type of birth control. 

The amount of time you’re on birth control may also be a factor. Multiple studies have shown that AMH doesn't change if you use combined oral contraceptive pills for less than six months. However, you may have a lower AMH if you’ve been a long-term user of the pill (or other hormonal methods). Thankfully, this is temporary – AMH levels typically rebound after a person stops using birth control.

‍

There are several other, less common causes for a low AMH level. These include:

• Genetic disorders that affect the X chromosome
• Medical treatments like radiation or chemotherapy
• Having surgery on your ovaries
• Losing one or both of your ovaries
• Autoimmune conditions

Factors that can influence AMH levels

It's important to know that some things can temporarily or even permanently change your AMH:

Birth control

Certain types of birth control can suppress your natural AMH levels. One study looked at data from women on various types of birth control and found: 

• Combined oral contraceptive pill led to 23.7% lower AMH
• Progestin-only pill led to 14.8% lower AMH
• Vaginal ring led to 22.1% lower AMH
• IUD led to 6.7% lower AMH
• Implant led to 23.4% lower AMH
• Copper intrauterine device led to 1.6% lower AMH

The authors concluded that birth control use is associated with a lower mean AMH level when compared to those who are not on contraceptives, with variation depending on the type of birth control

Health conditions

Things like PCOS, endometriosis, vitamin D deficiency, or even a recent ovarian surgery can impact your AMH levels.

Chemotherapy 

Chemotherapy treatments for conditions like cancer can significantly lower AMH levels. Research indicates that pre-chemotherapy AMH levels may be helpful in predicting ovarian function and potential fertility after treatment. A prospective study of women treated with chemotherapy for early breast cancer showed that long-term ovarian function after treatment was predictable using serum AMH levels before treatment. 

Obesity

Studies suggest a connection between obesity and lower AMH levels, though the exact relationship is complex. Obesity is linked to hormonal imbalances and inflammation, which can disrupt ovarian function and potentially affect AMH production. However, it's important to note that not everyone with obesity experiences lowered AMH, and other factors could also be at play. More research is needed.

Smoking

Studies have also shown that tobacco use, usually cigarette smoking, decreases AMH levels. This effect appears to be reversible though–it was only seen in people who were active smokers, not people who had previously smoked. 

What is a good AMH level for egg freezing?

Research has found that AMH is a good predictor of the response to ovarian stimulation and the number of eggs retrieved. Because of this, fertility doctors typically use your AMH levels (along with other biomarkers) to determine the drugs and dosages you will need to maximize your response to ovarian stimulation. 

Now, what about a correlation between AMH and actual babies born (live birth rate)? Well, while AMH does seem to have some association with live birth rates after IVF, its ability to actually predict a live birth is not that great. This is especially true for younger people. A 2021 study found that AMH is a good predictor of live birth in older (>39 years old), but not younger, people. They found that younger participants (≤38 years old) could get pregnant even with low AMH levels as long as they had frequent egg retrievals. 

Does AMH predict the number of eggs you will retrieve during egg freezing?

The overall success of an egg freezing cycle largely depends on the number and quality of eggs retrieved. Studies have shown that AMH levels can be used as a predictor of egg quantity, and can thus help to predict the potential success of egg freezing. Those with higher AMH levels tend to have better outcomes with egg freezing, as they are likely to have more eggs retrieved and a higher chance of success in future fertility treatments. 

But by no means does a high AMH level guarantee a lot of eggs during an egg retrieval procedure for fertility treatments. The number of eggs retrieved during an egg freezing cycle depends on several factors, including your age, ovarian response to stimulation medications, any other underlying medication conditions, and the skill of the fertility doctor performing the procedure.

When eggs are retrieved, only a portion of those eggs will be mature. A mature egg is one that’s ready and able to be fertilized. At most clinics, any non-mature eggs are discarded, though you can talk to your clinic about whether they’re open to freezing those too. 

Multiple studies have shown a strong correlation between AMH levels and mature eggs retrieved during egg freezing or IVF.

Let’s look at a few of the studies:

The study: Correlation between anti-Müllerian hormone, age, and number of oocytes 

Who: 1500 patients in Brazil between July 2012 and April 2019

The findings: “A positive correlation was found between serum AMH levels and total number of retrieved and mature oocytes from stimulated cycles”

‍

The study: Different anti‐Műllerian hormone (AMH) levels respond to distinct ovarian stimulation methods in assisted reproductive technology (ART) 

Who: 1,112 patients undergoing an egg retrieval as part of ART

The findings: “AMH showed a stronger correlation with egg number compared with age over a wide age range”

‍

The study: Relationship Between Anti-Müllerian Hormone and In Vitro Fertilization-Embryo Transfer in Clinical Pregnancy 

Who: 314 infertility patients with an average age of 31.0 ± 4.5 years

The findings: “the AMH level of women of all ages was positively correlated with the number of retrieved oocytes “

‍

The study: Antimullerian hormone (AMH) is a predictor of the number of eggs retrieved and D3 embryos in women with fluctuating and persistently elevated FSH levels 

Who: 58 women with fluctuating and persistently high serum day 3 (D3) FSH.

The findings: “These data demonstrate for the first time that serum AMH is a prognostic indicator independent of age and FSH of the number of eggs retrieved”

‍

The study: Random anti-Müllerian hormone (AMH) is a predictor of ovarian response in women with elevated baseline early follicular follicle-stimulating hormone levels 

Who: 73 women undergoing ART with elevated early follicular FSH levels

The findings: “Random AMH levels were strongly correlated with the number of oocytes retrieved during an ART cycle among women with elevated FSH”

What AMH do I need to donate my eggs?

Through Cofertility’s Split program, qualified freezers can freeze their eggs for free when donating half of the eggs retrieved to a family who can’t otherwise conceive. In the context of donating through our Split program, having an appropriate level of AMH is important. Fertility doctors typically consider an AMH level above 2.0 ng/ml as a good indicator for egg donation, and this is the benchmark used at Cofertility. Note that some clinics have a higher requirement.

This level suggests that you are likely to respond well to fertility treatments and produce a sufficient number of eggs for both donation and personal use. This allows us to proceed with the egg retrieval process in a manner that is both safe and effective.

However, if your AMH level is lower than this, it does not necessarily mean you cannot freeze your eggs. You can still qualify for our Keep program — where you keep 100% of eggs retrieved for your own future use — we offer exclusive discounts on expenses, such as frozen egg storage. Keep members also still gain free access to our Freeze by Co Community, a safe space for those engaging in the egg freezing process (or gearing up for it) to connect and lean on each other.

Everyone is unique, and AMH is just one factor of many that we consider during the evaluation process. You can learn more about qualifications for our Split program here. 

When should I test my fertility? 

So, when is the “right” age for testing your fertility, anyway? 

It depends.

And ultimately, it’s up to you! It’s your body, and your data, and there is no one-size-fits-all answer. We’re firm believers that knowledge is power and you deserve this information. Studies do show that our ovarian reserve declines with age — in other words, it’s a good idea to assess your fertility potential sooner rather than later. That way, if you do want to preventatively freeze your eggs, you can do so while your ovarian reserve is still higher. 

According to the American Society for Reproductive Medicine (ASRM), the optimal time to freeze your eggs is in your 20s and early 30s. This study also indicated that, as we get older, our chances of needing to do multiple egg freezing cycles increase in order to achieve a 70% live birth rate. We know we’re a bit of a broken record here, but: the younger you are, the healthier and more plentiful your eggs are.

Should I test my fertility at home or in a clinic?

At-home fertility tests have gained popularity in recent years due to their convenience and privacy. These tests typically involve collecting blood or urine samples and mailing them to a laboratory for analysis. On the other hand, in-clinic fertility tests are conducted at a medical facility, where specialized equipment and healthcare professionals are available.

The pros of at-home fertility tests include:

• Convenience and privacy: Samples can be collected in the comfort of your home.
• Cost-effective: At-home tests are often more affordable than in-clinic procedures.
• Early assessment: At-home tests allow you to gain insights into your fertility potential before actively trying to conceive. Plus, you won’t have to wait to get squeezed in for an appointment at the clinic!

The pros of testing your fertility at a clinic:

• A broader scope: At-home tests may not provide a comprehensive evaluation of fertility health, while testing your fertility at a clinic provides a more comprehensive picture of your fertility. An important note is, when testing your fertility at a clinic, you’ll also undergo a transvaginal ultrasound, where the technician or doctor will be able to get a view of what’s going on in those ovaries and the number of follicles available this cycle.
• Better accuracy: Some at-home tests may have varying levels of accuracy when compared to in-clinic tests.
• Facetime: At a clinic, you’ll have the ability to chat directly with a doctor, before and after your results.

If you do end up going with an at-home test, we have an exclusive discount with the LetsGetChecked Ovarian Reserve Test. It’s $139, and you can get 25% off with code COFERTILITY25. But there are many other options as well.

Although at-home fertility tests are a great way to get a peek behind the curtain of your fertility, they aren’t without limitations. For starters, according to recent studies, measuring AMH alone may not predict your time to pregnancy. As mentioned above, testing your fertility with a doctor at a clinic will likely provide a more comprehensive picture of your fertility outlook, especially as they consider your medical history, and conduct a physical exam and transvaginal ultrasound. Of course, you’ll also get professional interpretation of the results that you may not receive with an at-home fertility test. 

All of that being said, any fertility testing (whether at home or in a clinic) only measures your fertility at that given point in time. It should not be taken as a guarantee for future outcomes. It also can’t tell you anything about your egg quality, which cannot be truly observed until it comes time to actually fertilize those eggs. 

You are not a number

Repeat after me: you are more than one number! Your AMH level provides valuable insights into your ovarian reserve, but it’s just one piece of the puzzle when it comes to your fertility. AMH is always used as part of a full fertility evaluation, which often includes information about your medical history and age, a partner semen analysis, an ultrasound of the pelvis, an x-ray of the uterus and fallopian tubes, and/or additional lab work.

If that sounds like a lot, it is. This process can be overwhelming but focusing on the things that you can control can help you feel more grounded during your fertility journey, whatever that may look like.

Follicle-stimulating hormone, or FSH, is a hormone that plays an important role in your reproductive health. As a woman, understanding your FSH levels can provide insights into your fertility potential and help you make informed decisions about family planning, including egg freezing. But what exactly is FSH, and what do your levels mean? Let's dive in and explore this essential hormone.

What is FSH and why should you care?

FSH, short for follicle-stimulating hormone, is a hormone produced by your pituitary gland, a small but mighty gland nestled in your brain. Its job is to stimulate your ovaries to grow follicles, the tiny sacs that house your eggs. As these follicles mature, they release estrogen, which triggers ovulation – the release of an egg that's ready for fertilization.

Your FSH levels aren't static; they naturally fluctuate throughout your menstrual cycle, peaking right before ovulation. However, consistently high FSH levels, especially at the beginning of your cycle, can be a red flag for diminished ovarian reserve.  This means your ovarian reserve may be decreasing, either in quantity or quality. While it doesn't mean you can't get pregnant, it does signal that your fertility might be declining.

Average FSH levels by age

FSH levels naturally creep up as you age. And results also depend on where you are in your menstrual cycle. For females, here are normal FSH test results by life stage:

• Before puberty: 0 to 4.0 mIU/mL (0 to 4.0 IU/L)
• During puberty: 0.3 to 10.0 mIU/mL (0.3 to 10.0 IU/L)
• Females who are still menstruating: 4.7 to 21.5 mIU/mL (4.5 to 21.5 IU/L)
• After menopause: 25.8 to 134.8 mIU/mL (25.8 to 134.8 IU/L)

What is a good FSH level for egg freezing?

Most clinics consider an FSH under 9 as a good number for egg freezing. Above that threshold, the response to egg freezing medication tends to decline.  

Here's a general idea of what's considered normal FSH for females on cycle day 3:

• <9: Normal FSH level, expect a good response to egg freezing medication
• 9-11: Fair FSH level, the response to medication is reduced 
• 11-20: Reduced ovarian reserve and lower changes of live birth rate
• 20+: Very poor chances of response to stimulation, egg donation is generally recommended

Remember, these are just guidelines, and results vary by lab. Your doctor will interpret your FSH levels in the context of your age, medical history, antral follicle count, and other hormone levels to assess your overall fertility picture.

What abnormal FSH results may mean

Abnormal FSH results can be a sign of various underlying conditions related to fertility and reproductive health. 

High FSH Levels (typically 10 mIU/mL+ in premenopausal people) can suggest:

• Diminished Ovarian Reserve (DOR): This means the number of eggs in your ovaries are declining. 
• Primary Ovarian Insufficiency (POI): Also known as Premature Ovarian Failure (POF), this condition occurs when the ovaries stop working normally before age 40.
• Menopause: Naturally occurring decline in ovarian function leading to the end of menstruation.
• Polycystic Ovary Syndrome (PCOS): FSH levels are often higher in people with PCOS, a metabolic and hormonal disorder caused by high androgen (male sex hormone) levels. It can also cause enlarged ovaries due to an increased number of follicles on the outer edges. 
• Turner Syndrome: A genetic condition that can impact ovarian function, leading to a higher FSH.

If you get an abnormal result, your doctor will talk to you about what it could mean and if they suggest any next steps.

Testing your FSH

Getting your FSH levels checked is simple – it's just a routine blood test, typically done on the third day of your cycle. Your doctor may order additional tests, such as an antral follicle count (AFC) ultrasound or an anti-Mullerian hormone (AMH) test, to get a more comprehensive picture of your ovarian reserve.

Or, if you want to take a test at-home, there are a few convenient options:

• Natalist Women’s Fertility Test ($149) measures 5 hormones: estradiol, LH, FSH, TSH, and total testosterone. Get 20% off with code Cofertility20.  
• Modern Fertility Hormone Test ($179) measures 7 hormones: AMH, TSH, FSH, estradiol, prolactin, fT4, and LH

What you need to know about FSH tests: the fine print

While FSH tests are a valuable tool for understanding your fertility, there are a few important caveats to keep in mind:

• FSH levels fluctuate: Don't panic over a single high result. FSH levels naturally change throughout your menstrual cycle and as you get older. 
• FSH is not a diagnostic tool: An FSH test alone can't diagnose a specific condition like menopause or polycystic ovary syndrome (PCOS). It's just one piece of the puzzle, and your doctor will consider other factors to make a diagnosis.
• FSH is just one indicator of fertility: While an abnormal result (high baseline FSH) tends to be very predictive of low egg quantity, a normal result does not necessarily mean that the egg quantity is good. Some people with normal levels can still experience age-related fertility decline or have low quality eggs.
• Invalid in some cases: If you're taking hormone therapies like birth control pills, FSH tests might not be accurate. Be sure to let your doctor know about any medications you're taking before the test.

The bottom line? FSH tests provide valuable information, but they're not the be-all and end-all of fertility assessment. Talk to your doctor about your results and what they mean for your individual situation.

The bottom line: knowledge is power

While FSH tests are a valuable tool for assessing ovarian reserve and determining if egg freezing could be a fit, it's important to remember that they're just one piece of the puzzle. A single FSH result doesn't define your fertility journey, and your doctor will consider various factors, including your age, medical history, AFC, and other hormone levels, to develop a comprehensive picture of your reproductive health.

If you're considering egg freezing or have concerns about your fertility, don't hesitate to consult with a fertility specialist. They can help you interpret your FSH results, discuss your options, and guide you towards the best path for achieving your family-building goals. Understanding your FSH levels is a crucial step towards taking control of your fertility and shaping your future.

Egg freezing, also known as oocyte cryopreservation, is a process where a woman's eggs are retrieved, frozen, and stored for later use. This allows women to preserve their eggs at their current age, potentially increasing their chances of having a biological child in the future.

Egg freezing is becoming more and more common, with a 30% increase in egg-freezing cycles from 2021 to 2022 alone! 

I’m Dr. Meera Shah, a double-board certified OBGYN and Reproductive Endocrinologist (REI). I have helped countless women freeze their eggs as a fertility doctor and as a Medical Advisor to Cofertility. This article is a guide to everything you need to know to make a confident, informed decision about egg freezing.

Why people choose to freeze their eggs

There are many reasons why women opt for egg freezing. Here are some of the most common reasons we hear:

• Focusing on other priorities: Women focusing on career or personal goals can freeze their eggs until they're ready to start a family.
• Waiting for the right partner: As the average age of first marriage continues to rise, some women choose to freeze their eggs instead of rushing into a marriage.
• Medical reasons: Women facing medical conditions or treatments that could impact fertility, such as chemotherapy or radiation, can freeze their eggs before undergoing these treatments.
• Genetic predisposition: Women with a family history of early menopause may choose to freeze their eggs to ensure they have viable eggs for future use.
• Peace of mind: Some women simply want the peace of mind knowing they have a backup plan for their fertility.

At what age should you freeze your eggs?

There is no perfect age at which to freeze your eggs. However, the younger you can do it, the better. According to the American Society for Reproductive Medicine (ASRM), an optimal time to freeze your eggs is in your 20s and early 30s, while you have a higher ovarian reserve and eggs are healthier. 

A large 2020 study at a fertility clinic that specializes in this area looked at egg freezing cycles for over 1,200 people. It compared the average number of eggs people of different ages were able to freeze versus the “optimal” or goal number of eggs they should freeze. This goal number was based on how many eggs would give them a 70% live birth rate after doing 1 or 2 egg freezing cycles (this rate is calculated using some other numbers and it typically goes up as we age to make up for the lower number of healthy eggs). 

The study found that younger people, unsurprisingly, have an easier time freezing the goal number of eggs in one cycle. As people aged, they needed multiple egg freezing cycles to reach that goal number.

Is it worth freezing eggs after age 35?

The findings from the study above bring up a common question–is it worth freezing eggs after age 35? Well, it depends. The ASRM does not recommend egg freezing for people older than 38, but this isn’t a strict cutoff. 

Your biological clock is not a cliff. Everyone’s fertility decreases down at a different rate. Having your fertility hormones checked can sometimes help you and your doctor get a general idea of your ovarian reserve and chance of a future pregnancy. This can better help you decide if egg freezing is right for you.

Egg freezing success rates by age

Success rates with egg freezing depend on a lot of factors: your health, your ovarian reserve, your response to egg freezing medication, and the quality of the clinic. That being said, generally, younger women have higher success rates due to better egg quantity and quality. 

A study of 1,241 women found that the average number of eggs retrieved on the first egg freezing round was:

• 21 eggs for women under 35
• 17 eggs for women 35-37
• 14 eggs for women 38-40

‍

Because women in their 30s tend to produce less eggs, at this age you may end up having to either settle for fewer eggs for freezing or undergo multiple rounds to collect enough eggs to have on hand for later implantation. As you can imagine, those costs can creep higher and higher the more rounds you endure. 

Now, you might be thinking: isn’t 14 eggs a lot?  It’s true that eggs retrieved from women under the age of 36 will have a 95 percent survival rate after being thawed.  But, not all thawed eggs will become viable embryos and lead to a live birth. The probability of a live birth varies with the age of the woman trying to conceive and the number of mature eggs available. In short, the older the woman, the more eggs required to achieve a high probability of a live birth. 

A study in the Journal of Assisted Reproduction and Genetics further supports this point. For example, a woman under 35 will need nine eggs to achieve a 70% chance of having at least one live birth. If you’re trying to conceive in your mid to late 30s, you may need double as many eggs to achieve that same 70% success rate. 

The right number of eggs to freeze for your age

Different folks have different reasons for freezing their eggs. Some may be thinking about prolonging their fertility into the future. Others may be freezing some eggs but also hoping to donate some eggs to help others grow a family — something that’s done via our Split program, where you freeze for free when donating half of the eggs to a family that can’t otherwise conceive. 

Either way, studies have found that the optimal number of eggs to freeze really comes down to your age. That’s because the number of eggs in the body isn’t the only thing to decrease as you get older — egg quality decreases too, and egg quality is the number one factor in determining whether an egg can eventually result in a live birth. 

Here are the number of eggs you’ll want to freeze based on your age in order to obtain an optimal live birth rate:

Should I do multiple egg retrievals?

What happens if you don’t get as many eggs as you had hoped during your egg retrieval cycle? 

If you’ve undergone one round of egg freezing and the number of eggs your reproductive endocrinologist retrieved from your ovaries wasn’t as high as you’d hoped, you may want to talk to them about trying again. A fertility specialist can help you talk through all of your options.

There is technically no limit to the number of egg freezing rounds a person can undergo, but it’s not recommended that egg donors undergo more than six cycles. If you’re hoping to split your eggs with intended parents (donating half of the eggs retrieved) as part of our Split Program, you may find that additional retrievals help you provide the optimal amount of eggs for a live birth for you and for the intentend parents too. 

The right number of eggs to freeze to have multiple children

If you’re planning to have a big family one day, you may want to look at the number of eggs it’s recommended you freeze to achieve one live birth and talk to your Reproductive Endocrinologist (REI) about freezing more eggs. 

As we shared above, a woman under age 35 will need to freeze about nine eggs to achieve a 70% chance of a successful pregnancy and live birth. If you’re under age 35 now and thinking you might want to use frozen eggs to conceive twice in your future, you will want to freeze closer to 18 eggs.

The number of eggs necessary will increase with your age at time of the retrieval, and the number of children you hope to have via those eggs. 

Can frozen eggs guarantee a successful pregnancy in the future?

When trying to decide if you should freeze your eggs, it’s important to know that egg freezing is not an “insurance policy” for your fertility. While egg freezing can take some of the stress of having a baby right now off your shoulders, it is not a guarantee that you’ll have a baby in the future. 

Why not? Well, for one, not all the eggs that get frozen will actually be viable. It’s expected that some eggs will not survive the warming process when it comes time to use the eggs. In addition, the chances of the eggs that do survive being successfully fertilized depends on a variety of factors, including how old you were when you froze them (more on this later). 

This is not to sway your decision one way or another. Ultimately, only you and your doctor can decide if egg freezing is the right decision for you. But it's important to go in knowing that it’s not meant to be a done deal. As egg freezing has gotten more popular, many companies will gloss over this fact. We don't think that's right and want to be straight with you from the outset.

Freezing your eggs when you’re unsure if you want kids

Perhaps the biggest benefit of egg freezing is that it puts the decision-making power entirely in your hands. Whether you’re freezing your eggs because you want to focus on your career or you’re about to undergo medical treatment that may affect your fertility later on, or you’re waiting to find the right partner, freezing your eggs allows you to preserve some of your fertility independently. 

While you might not be sure about having kids today, if you do decide you want kids down the road, especially if you’re in your mid- to late-thirties, having eggs on ice will increase the chances that you’re able to do so.

Know this: most people do not regret their egg retrieval procedure. We looked at five studies on egg freezing. The rates of regret reported in these studies varied, likely due to the sample size, study design, and the follow-up period. However, taken together, these studies suggest that the vast majority of those who freeze their eggs have zero regrets.

There also appear to be factors that reduce the chances of regret, including feeling fully informed beforehand, and getting adequate support during the egg freezing process. In other words, if you take the time to think things through and feel supported throughout the journey, you’re less likely to regret making this decision for yourself.

The egg freezing process: step-by-step

The egg freezing process is about a two-week journey. You will work closely with a Reproductive Endocrinologist (fertility doctor) and the clinic team throughout the process. 

Here's a detailed breakdown of what you can expect from start to finish, and beyond:

1. Ovarian stimulation: You'll take hormone medications to stimulate your ovaries to produce multiple eggs, and have multiple monitoring appointments and blood tests to see how the eggs are maturing.
2. Egg retrieval: Your eggs will be retrieved through a minor surgical procedure using ultrasound guidance.
3. Vitrification: Your eggs will be rapidly frozen using a technique called vitrification, which helps preserve their quality.
4. Storage: Your frozen eggs will be stored in a secure facility until you're ready to use them.
5. Thawing and fertilization: When you're ready to conceive, your eggs will be thawed, fertilized with sperm (either your partner's or a donor's), and transferred to your uterus.

Will egg freezing hurt my future fertility?

Egg freezing actually rescues all the other eggs that your body would otherwise allow to die during a normal menstrual cycle. So the process of egg freezing doesn’t take anything away from your egg reserve, it actually helps you save some extra eggs! And since during each cycle, your body goes through the ovulation process again with a new set of competing eggs, your chances of getting pregnant unassisted in the future also aren’t affected by egg freezing. 

What egg freezing does do is give you additional options for if and when you’re ready to start growing your family.

Is egg freezing safe?

Like any other procedure, there are risks and side effects when freezing eggs, including risks of anesthesia, bleeding, pain, and infection. Thankfully, the majority of people who go through with it deal with side effects for a few days at most. When it comes to the ovaries themselves, they generally recover quickly. The overall data indicate that the potential risks of surgical complications from egg retrieval are generally very small. However, in people with a history of endometriosis, pelvic inflammatory disease, pelvic adhesions or previous pelvic surgery, the risks are slightly increased so make sure to speak to your doctor about your medical history if you fall into any of these categories.

Egg freezing vs embryo freezing 

There’s one major difference between freezing eggs and freezing embryos. When you freeze your eggs, they stay unfertilized. We all know that to make a baby, you need an egg and a sperm because each of them provides half of the material needed. On its own, an egg can’t function (and neither can a sperm).

An embryo, on the other hand, is an egg that has already been fertilized by a sperm. Once they combine, the egg and sperm become a single cell. Over the next three to four days, the embryo divides several times, going from one to two to four to eight cells, and so on until it reaches the blastocyst stage and is ready to be frozen. Once an embryo has developed, there’s no going back– that is, there’s no way to turn that embryo back into a separate egg and sperm. 

If you don’t know who you want to have children with, then freezing your eggs may be the best approach. This option gives you the freedom to hold off on thinking about having a baby until you’ve met someone or are ready to choose a sperm donor. 

On the other hand, if you are currently with a partner who you know you’d like to have children with but now isn’t the right time, then frozen embryos might be the way to go with the goal of a future embryo transfer. The caveat here is to be 100% certain—stars like Sofia Vergara and more recently, Anna Kendrick, have run into trouble after freezing embryos with partners they didn’t end up with.

Cost of egg freezing

The question of how much does it cost to freeze your eggs will come down to a few factors. These include the number of cycles you undergo to retrieve eggs and how long you keep the eggs in storage. Overall, the typical egg freezing can cost anywhere from $10,000 to $20,000 for one cycle plus the cost of storage fees.

Another option? Freeze by Co offers women a chance to freeze their eggs for free when they donate half of the retrieved eggs to a family that can’t otherwise conceive. The cost of the entire process, including 10 years of cryopreservation, is fully covered — we think it’s a win-win. 

Or, if you want to freeze and store your eggs for your own future use without donating, Freeze by Co offers lower prices on things like consultations and storage, along with access to our community of freezers. ‍We partner with lenders, like Sunfish, to offer you fertility financial resources.

Learn more about egg sharing

Egg sharing programs exist worldwide to help make fertility care more accessible. Egg sharing is when a woman undergoes an egg retrieval, and some of the resulting eggs are donated to a family that can’t otherwise conceive.

In Cofertility’s Split program, women can freeze their eggs for free when they donate half of the retrieved eggs to a family who can’t otherwise conceive. 

Ask us anything

If you’d like help figuring out when to freeze your eggs, you can contact us for more information. While every woman’s fertility preservation path differs, we can connect you with reputable clinics who can offer basic guidance about when the time is right for you to freeze your eggs during a consultation or dig into specifics by going through a preliminary exam in a provider’s office.

We understand that the timing may not be right for you to start a family right now, but that doesn’t mean it’s too early to start thinking about what choices will be available to you when that time comes. As you can see, a lot goes into preparing for an egg retrieval process.  The earlier you consider your fertility, the more options you’ll have. 

Whether you decide to freeze or not, we’re here for you to answer any questions or talk through any concerns. 

As you embark on your egg freezing journey, you're likely to encounter a whirlwind of medical terms, tests, and metrics that can feel overwhelming at first. Among these is an especially important one: the Antral Follicle Count (AFC). This key indicator plays a significant role in understanding your chances of success with egg freezing by measuring the number of follicles in your ovaries.

But what exactly is AFC, and why does it matter so much? More importantly, is it a fixed number, or can it change over time? These are questions that many folks grapple with as they navigate egg freezing.

In this article, we'll dive into the world of AFC, demystifying this important metric and exploring its variability. We'll break down the science in a way that's accessible and relevant to your egg freezing journey, helping you understand what your AFC means for your fertility and how it might influence your treatment plan.

Whether you're just starting to consider egg freezing or you're already in the midst of the process, understanding AFC can empower you to make informed decisions about your reproductive future. It's not just about numbers on a chart; it's about gaining insight into your body's unique fertility landscape and working with your healthcare team to optimize your chances of success.

By the end of this article, you'll have a clearer understanding of what AFC is, how it's measured, why it matters, and yes - whether it can change. Armed with this knowledge, you'll be better equipped to navigate your egg freezing journey with confidence and clarity.

What is AFC and how is it measured?

Antral Follicle Count is a key indicator of your ovarian reserve - essentially, it's a snapshot of your egg supply. Whereas AMH measures your ovarian reserve through a hormone blood test, AFC is an actual look at your antral follicles, which are small fluid-filled sacs containing immature eggs. But what is an ovary follicle exactly? An ovary follicle is a structure within the ovary that contains a developing egg. To assess AFC, a fertility doctor performs a transvaginal ultrasound, typically early in your menstrual cycle, to count these follicles in your ovaries.

The number of visible follicles, your AFC, is a helpful predictor of how your ovaries might respond to fertility medications during the egg freezing process. A higher count generally suggests a better ovarian reserve and potentially more eggs that can be retrieved.

Fertility doctors use this information to tailor your treatment plan, determining which medications to use and in what doses. It's like creating a personalized roadmap for your egg freezing journey.

Does AFC change within a cycle?

While it's often recommended to perform the AFC early in your menstrual cycle, experts suggest that it can be assessed at various points. However, it's important to remember that there can be some fluctuation depending on when the ultrasound is done. In fact, studies have shown that AFC can vary by as much as 30-34% within a single cycle. This variability is worth keeping in mind as you interpret your results.

Can AFC change month to month?

Does antral follicle count change? Yes, your AFC isn't set in stone. Indeed, it can vary from one menstrual cycle to the next. This variability is one reason why fertility specialists often consider AFC alongside other markers, like Anti-Müllerian Hormone (AMH) levels, to get a more comprehensive picture of your ovarian reserve.

Remember, AFC correlates with the number of eggs retrieved during an IVF cycle, which is why it's such a valuable predictor for egg freezing outcomes.

A very low AFC (typically less than 5-7) is associated with a smaller number of eggs retrieved and potentially reduced pregnancy rates down the line. On the flip side, a high AFC (20 or more) could indicate a risk of ovarian hyperstimulation syndrome (OHSS) during fertility treatments.

Can I increase my AFC?

While AFC generally declines with age, there are factors that can influence it. For instance, if you're using hormonal contraceptives or certain other medications, your AFC might appear lower than it actually is. Once you stop these medications, you might see an increase in your AFC.

To increase your chances of a successful egg freezing cycle, optimize your fertility health as soon as possible. This step will look a little different from person to person since everyone has their own unique medical history and concerns. Generally speaking though, optimizing your health will include following a balanced diet and making other healthy lifestyle choices. In some cases, you may want to consider adding certain vitamins and supplements to your regimen too. Make sure to talk to your fertility specialist if you’re not sure!

You may also want to consider doing multiple egg retrieval cycles. If you have the resources and time to do multiple cycles, this can vastly improve the pool of eggs to choose from in the future. This is an especially helpful option for people who are older or have a low AFC. If your fertility provider thinks more cycles will improve your chances, they’ll discuss those recommendations with you.

What is a normal AFC by age?

The normal range of antral follicle count can vary depending on your age. In general, those who are younger tend to have a higher number of antral follicles, indicating a larger ovarian reserve. As a person ages, the number of antral follicles naturally declines, reflecting the diminishing ovarian reserve.

While the specific numbers can vary, a typical AFC for someone in their 20s and early 30s may range between 10-20 follicles, in their late 30s around 8-15 follicles, and by their 40s, it could further decline to under 10 follicles. It's important to remember that these numbers are approximate and can vary based on individual factors such as genetics and overall reproductive health.

One study of infertile women looked at exactly how antral follicle count declines with age, finding the median AFC to be:

• 14 at age 25
• 12 at age 30
• 10 at age 35
• 8 at age 40
• 6 at age 45

What does this mean for you?

Understanding the variability of AFC can help you approach your egg freezing journey with realistic expectations. If your first AFC measurement isn't what you hoped for, remember that it can change. Your fertility doctor might recommend retesting in a subsequent cycle or adjusting your treatment plan based on your individual AFC trends.

Remember, AFC is just one piece of the puzzle. Your age, overall health, and other fertility markers all play crucial roles in determining your egg freezing outcomes. The goal is to create a personalized plan that gives you the best chance of success.

As you navigate this process, don't hesitate to ask your fertility doctor questions. Understanding your body and your options is empowering, and it can help you make informed decisions about your fertility preservation journey.
