amh

Anti-Mullerian hormone (AMH) is a hormone produced by the follicles in the ovaries (the fluid filled sacs that contain eggs). It requires a simple blood draw and is most often used as a marker of ovarian reserve. Ovarian reserve is the term for the number of healthy eggs left in your ovaries. Since people with ovaries are born with a fixed number of eggs, this number naturally declines over time. 

A low AMH level is usually related to natural aging, but it can also have other causes. In this article, we’ll explore what a low AMH result means and answer some common questions that can come up.

AMH and its role in fertility

So what exactly can AMH tell you about your fertility? As mentioned, 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.

What is a low AMH result?

As with most things in medicine, there’s no absolute answer here. What is considered a low, normal, or high AMH level depends on your age and the lab where you take the test. Since there is no international standard, it’s best to use the reference ranges that come with your test results.

In general, an AMH between 1.0 and 3.5 ng/mL is considered to be in the “normal” range, which means you’re likely to have a good response to fertility treatments. Anything below 1.0 ng/mL is considered low and a sign of a declining ovarian reserve.

What does a low AMH mean?

Having a low AMH level can be a sign that your ovaries are making less of the preantral follicles. The lower the number of follicles, the lower your ovarian reserve is. 

So what does this mean in terms of fertility?

First, having a lower AMH does not automatically mean you aren’t ovulating regularly or that you won’t be able to get pregnant naturally or with assisted reproductive technologies. However, research has found that what AMH is good at predicting is the response to ovarian stimulation and the number of eggs retrieved, regardless of a person’s age. So, someone with a higher AMH is generally expected to be able to get more eggs in one cycle than someone with a lower AMH. Because of this, fertility doctors typically use AMH levels (along with other information) to figure out the drugs and dosages you’ll need to maximize your response to ovarian stimulation medications. 

If you’re trying to conceive naturally, you’ll be glad to hear that multiple studies have shown that AMH does not correlate with how likely you are to actually get pregnant. In fact, one study looked at levels of AMH, FSH, and another ovarian hormone, inhibin B and tracked people for a year. They found that there was no correlation between someone’s ovarian reserve and their ability to conceive and that a low ovarian reserve was not associated with lower fertility. As a result, they did not recommend the use of FSH or AMH levels to “assess natural fertility.”

Reasons AMH would be low

There are a few reasons that could explain a low AMH. Let’s explore them.

Natural decline with aging

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. 

Hormonal birth control

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.

You can learn more about birth control and AMH here.

Tobacco use

Studies have 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. 

Less common causes 

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.

Can I still donate my eggs with a low AMH?

If you are looking to donate your eggs, minimum AMH requirements are usually 2.0 or above. With Cofertility’s Split program, we require a minimum AMH of 2.0, though clinics may have their own unique requirements. This is to increase the chances of retrieving enough eggs to actually split, to ensure positive outcomes for both parties involved.

What to do if you have a low AMH result

Finding out you have a low AMH can be disheartening, especially if you had future fertility plans that you’re worried may be affected. While there’s unfortunately not much that can be done to reverse a low AMH, there is still hope for starting a family someday even with a low AMH. With the exception of birth control or cigarette smoking, most studies have shown that lifestyle changes like diet or supplements have an insignificant effect on AMH levels but despite this, I promise it’s not all gloom and doom. 

Let’s go through a few things you can do as you move forward with this new information. 

Lean on your village

The first thing to do is take a deeeeeep breath… There are a lot of nuances involved here which can make it hard not to get lost in the weeds. Fertility is impacted by so many different things that you can drive yourself crazy trying to manage all of them. 

Having friends, family, and mental health specialists available to support you when you need it is going to be crucial. Navigating fertility is hard no matter what, so having people around you who you can lean on on bad days and celebrate with on good days will help immensely. 

Consult a fertility specialist

Speaking of your village, it should definitely include a fertility specialist. Consulting with a fertility doctor can help you better understand your reproductive health and provide guidance on any concerns or questions you may have. They’ll be able to review your specific options and work with you on a plan that helps you reach your family-building goals. This treatment plan will depend on a lot of things including how soon you want to have a child, how many children you want to have, your finances, and your desire to have a child who is genetically related to you. 

So does this mean I have to freeze my eggs ASAP?

This is typically the first question people ask and the answer is not necessarily. As mentioned before, there are many other factors involved in assessing your fertility and modern technology has allowed for advances that make family building a possibility for virtually everyone. Your fertility specialist will be able to discuss all the options for starting a family based on your unique family-building goals. This could certainly include freezing your eggs for later use but it could also mean trying to conceive unassisted, undergoing IVF with your own eggs or with donor eggs, using a gestational carrier, or even options beyond these. Again, this is something that will require you to examine your personal goals and work with your provider to figure out the best way to reach them. 

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.

Anti-Müllerian hormone (AMH) has gained significant attention in the field of reproductive medicine as a valuable marker of ovarian reserve. It provides insight into egg quantity and can be useful in assessing fertility health and predicting the chances of egg freezing success. 

However, there are certain medications that can potentially influence AMH levels, raising questions about the accuracy and interpretation of AMH testing while on them. In this article, we will explore the relationship between medications and AMH levels, shedding light on the impact of specific drugs and discussing their implications for women's reproductive health.

What is AMH?

AMH is a hormone produced by the cells within ovarian follicles. Its primary role is to promote the growth and development of follicles. AMH levels are generally stable during the menstrual cycle, making it a reliable marker for assessing ovarian reserve. It is measured through a simple blood test and has become an important tool in fertility evaluations and treatment planning.

What causes AMH to change?

AMH levels naturally decline as we age. The highest levels of AMH are typically found in women during their early reproductive years, and the levels gradually decrease as we approach menopause… making age the most common reason for AMH to change.

But there are other reasons AMH may change over time. The most common reason is simply age. Since AMH is considered a reliable marker of ovarian reserve, which refers to the quantity of eggs remaining in the ovaries, this hormone naturally decreases as we get older.

Certain medical conditions, such as ovarian tumors, can also affect AMH levels. Additionally, treatments like chemotherapy or radiation therapy that target the ovaries can significantly reduce AMH levels.

While the direct impact of lifestyle factors on AMH levels is not yet fully understood, some studies suggest that factors such as smoking, obesity, and extreme exercise may be associated with lower AMH levels. However, more research is needed to establish definitive conclusions.

Lastly, certain medications can impact AMH levels. For example, oral contraceptives and drugs like clomiphene citrate used in fertility treatments can temporarily decrease AMH levels. On the other hand, supplements like DHEA (dehydroepiandrosterone) and vitamin D have been associated with increased AMH levels. We’ll go more into detail about these below.

Remember that individual variations exist, and AMH levels should be interpreted in conjunction with other fertility assessments to gain a comprehensive understanding of your reproductive health. If you have concerns about your AMH levels or fertility, it's best to consult with a fertility doctor for personalized guidance and recommendations.

What medications can affect AMH levels?

Several medications have been found to influence AMH levels, potentially complicating its interpretation as a marker of ovarian reserve. Here are some examples:

Oral birth control 

Oral contraceptives are commonly used for birth control and to regulate menstrual cycles. Studies have suggested that oral contraceptive use may lead to decreased AMH levels in the short term.

One study compared the AMH levels of 228 hormonal contraception users and 504 non-users. They found that users of birth control had 29.8% lower AMH concentrations. Because of this, the authors concluded that AMH may not be an accurate predictor for women using hormonal contraception.

You may want to consider the timing of the AMH test when using hormonal contraceptives. Estrogen can suppress the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are necessary for the development and maturation of follicles. 

As AMH levels are influenced by FSH and LH, you could wait for a few weeks after discontinuing birth control before measuring AMH levels for a more accurate assessment of ovarian reserve. Or, you could take the test knowing the results may be lower due to birth control. It’s best to discuss this with your doctor.  

Metformin

Metformin is a medication commonly used in the treatment of polycystic ovary syndrome (PCOS), a complex endocrine disorder associated with metabolic and reproductive disturbances, and for managing insulin resistance. Research has shown that metformin use may be associated with decreased AMH levels.

Clomiphene Citrate

Clomiphene citrate (brand name Clomid©), is a medication used to stimulate ovulation in women who are trying to conceive. Similar to metformin, clomiphene citrate has been associated with decreased AMH levels. When undergoing fertility treatments involving clomiphene citrate, you’ll want to take this potential impact into account when interpreting AMH results.

What supplements can affect AMH levels?

Dehydroepiandrosterone (DHEA)

DHEA is a natural hormone that can be converted into other hormones in the body, including testosterone and estrogen. Some studies have suggested that supplementation with DHEA may lead to increased AMH levels. These findings suggest that certain nutritional interventions may have a positive effect on ovarian reserve.

Vitamin D

Vitamin D is essential for overall health and has been linked to various biological processes in the body, including reproductive health. Some research indicates that vitamin D supplementation may lead to increased AMH levels. However, more studies are needed to fully understand the relationship between vitamin D and AMH levels.

Is there anything I can take to increase AMH levels?

While there are medications and supplements that have been associated with changes in AMH levels, the impact of these medications is typically temporary or specific to certain conditions. 

Currently, there is no definitive medication or treatment specifically designed to increase AMH levels. However, there are lifestyle factors that may positively influence overall reproductive health, such as maintaining a healthy weight, adopting a balanced diet, managing stress levels, and avoiding smoking and excessive alcohol consumption. These lifestyle choices can contribute to optimal ovarian function and potentially support healthy AMH levels.

Summing it up

AMH testing has revolutionized our ability to assess ovarian reserve and guide fertility treatment decisions. However, it's crucial to consider the potential influence of certain medications on AMH levels. Understanding how specific drugs and supplements may affect AMH results can help you interpret the findings accurately and make informed decisions about fertility treatments. 

Remember that these effects are usually temporary or specific to certain conditions. It's always best to consult with your fertility doctor who can provide personalized guidance based on your specific situation. 

Better yet, focusing on maintaining a healthy lifestyle, managing stress levels, and adopting a balanced diet can contribute to overall reproductive health and support optimal ovarian function. By staying informed and working closely with your healthcare team, you can navigate the complexities of AMH testing and make informed decisions about your fertility journey.

Cofertility is a human-first fertility ecosystem rewriting the egg freezing and egg donation experience. With our Freeze by Co platform, women can freeze their eggs for free when they donate half of the retrieved eggs to a family who can’t otherwise conceive. We are obsessed with improving the family-building journey — today or in the future — and are in an endless pursuit to make these experiences more positive.

In the world of reproductive health and fertility, there is a growing interest in understanding the quantity of eggs a woman has, also known as ovarian reserve. The concept of measuring ovarian reserve has gained popularity as more people seek to assess their fertility potential and make informed decisions about family planning. 

But can you truly measure how many eggs you have? Let's delve into the world of ovarian reserve testing and explore the possibilities and limitations.

How many eggs do females have?

Females are born with approximately one to two million oocytes, and it only goes down from here since no new eggs are made. But here's where it gets interesting.

Once we reach puberty, a process triggered by a complex interplay of hormones, only about 300,000 of these oocytes will remain. These precious few will have the opportunity to mature and potentially be released as eggs during our reproductive years. Our bodies typically release just one egg per menstrual cycle, and this process occurs approximately 400 times throughout our lifetime.

These remaining oocytes are not merely passive bystanders. Each one resides within a protective structure called a follicle, where it lies dormant and suspended in the middle of a cell division. Remarkably, the lifespan of an egg is one of the longest among the body's cells. However, this extended duration can also increase the chances of damage and genetic abnormalities as we age.

At menopause, which is defined as one year after your last menstrual period, the pool of remaining oocytes steadily declines until none remain. This natural process signifies the end of our reproductive years.

Understanding the intricacies of egg development and the limited supply available underscores the importance of considering fertility and family planning at an earlier age. Each egg is a precious resource, and its quality and viability can impact the chances of achieving a successful pregnancy. Exploring fertility preservation options, such as egg freezing, can provide women with greater control over their reproductive future.

While the numbers presented here provide a general understanding, it's crucial to remember that everyone’s ovarian reserve is unique. Factors like genetics, lifestyle, and overall health can influence the rate of egg loss and fertility potential. 

Egg count and age

As stated above, females are born with one to two million eggs. By puberty, only about 300,000 of these oocytes will remain. After starting the menstrual cycle, we lose about 1,000 immature eggs every month… meaning by age 37 there are around 25,000 eggs remaining. And by menopause, no more eggs remain.

Here is a rough chart of what this could look like for an individual. Keep in mind that everyone starts with a different number of eggs, and everyone’s rate of decline varies. This chart is just to give you an idea of what this egg count could look like: 

Measuring egg reserve (aka ovarian reserve)

Ovarian reserve refers to the number of eggs remaining in a woman's ovaries at a given time. It is one indicator of a woman's reproductive health, and can help guide fertility treatment decisions. The idea of quantifying ovarian reserve has gained significance as women strive to gain insights into their fertility and make proactive choices about their reproductive journey. And at the same time, at-home tests make it easier to measure your ovarian reserve.

Keep in mind that the number of eggs you have does not necessarily equate to your ability to conceive. Other factors, such as egg quality, the presence of any reproductive disorders, and the overall health of the reproductive system, play significant roles in fertility. Not to mention the health of the sperm! Some people have lower ovarian reserve but still achieve successful pregnancies, while others with a seemingly healthy ovarian reserve may face challenges in conceiving.

How to measure ovarian reserve

One of the most commonly used methods to measure ovarian reserve is through a blood test that evaluates specific hormone levels. These hormones include anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol. AMH, in particular, has emerged as a reliable marker of ovarian reserve, as it reflects the number of small follicles in the ovaries that contain immature eggs. Low levels of AMH may indicate a diminished ovarian reserve, while higher levels may suggest a larger pool of eggs.

While ovarian reserve testing provides valuable insights, it is not a crystal ball that can predict fertility outcomes with absolute certainty. Ovarian reserve is just one piece of the fertility puzzle, and other factors such as egg quality, uterine health, and sperm quality also play crucial roles in the conception process. Additionally, fertility is influenced by various external factors, including age, lifestyle, and underlying health conditions.

Fertility testing can provide a snapshot of ovarian reserve at a specific moment in time. Ovarian reserve naturally declines with age, and the number of eggs available for fertilization decreases over time. Therefore, it's crucial to interpret the results in the context of your age and overall health.

Egg reserve testing methods

Another consideration when evaluating ovarian reserve is the variation in testing methods and reference ranges used by different laboratories. Each laboratory may have its own set of standards and measurements, which can lead to variations in results. You may want to consult with a fertility doctor who is knowledgeable in reproductive medicine to interpret the test results accurately and provide personalized guidance (if you work with Cofertility, we can help you set this up).

So, can you measure exactly how many eggs you have?

While ovarian reserve testing can provide valuable information, determining the exact number of eggs a woman has remaining in the ovaries is not possible. 

Why? First of all, the number of eggs in the ovaries is not static but rather dynamic and constantly changing. We are born with a finite number of eggs, and this number gradually declines over time through a process called follicular atresia. This natural process of egg loss occurs throughout our reproductive years, and the rate of decline varies from person to person.

Second, the accuracy of measuring the exact number of eggs is hindered by the limitations of current medical technology. While imaging techniques like ultrasound can visualize the presence of ovarian follicles, they cannot precisely determine the number of eggs within each follicle. Additionally, even if the number of follicles can be counted, it does not equate to the exact number of eggs, as not all follicles contain a viable egg.

Ovarian reserve is just one piece of the puzzle

While ovarian reserve testing can provide valuable information, it is just one tool in the broader landscape of fertility assessment. A fertility doctor can consider your medical history, conduct a physical examination, measure your antral follicle count, and may recommend additional tests or imaging studies to provide a comprehensive assessment of your reproductive potential.

With our Freeze by Co platform, women can freeze their eggs for free when they donate half of the retrieved eggs to a family who can’t otherwise conceive. We are obsessed with improving the family-building journey — today or in the future — and are in an endless pursuit to make these experiences more positive.

If you are considering starting a family or have concerns about your fertility, understanding the concept of ovarian reserve is essential. Ovarian reserve refers to the quantity of eggs (oocytes) available for fertilization. It serves as a key indicator of your reproductive potential and can play a crucial role in fertility treatment decisions. 

In this guide, we will delve into the topic of ovarian reserve, exploring its significance, how it is assessed, factors that affect it, available options for optimizing fertility, and emotional considerations related to fertility journey.

First off, what does your ovarian reserve mean?

Simply put, your ovarian reserve is your fertility potential, which is influenced by a variety of factors, including age, genetics, and certain medical conditions.

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, like myself, evaluate the likelihood of successful pregnancy, and guide you in making informed decisions regarding family planning and fertility treatments.

How do I know my ovarian reserve?

If you want to know your ovarian reserve, it’s best to set up time for a fertility assessment with a fertility doctor (reach out – we can help with this!). 

There are two ways a doctor can help assess your ovarian reserve, including:

Blood hormone tests

Hormone tests, including follicle-stimulating hormone (FSH), estradiol, luteinizing hormone (LH), anti-Müllerian hormone (AMH), and estradiol, provide valuable information about ovarian function and egg supply. While AMH can be taken any time, FSH and LH are typically performed on specific days of the menstrual cycle to obtain accurate results.

Antral follicle count

Transvaginal ultrasound is used to visualize the ovaries and count the number of antral follicles present. Antral follicles are small, fluid-filled sacs that contain immature eggs. The count of antral follicles serves as an indirect indicator of ovarian reserve.

By combining the results of hormone tests and ultrasound assessments, we can estimate your ovarian reserve and provide insights into fertility potential.

What is a normal ovarian reserve?

Determining what constitutes a “normal” ovarian reserve involves comparing your results to established reference ranges for your age. Age-specific reference ranges serve as benchmarks to evaluate your ovarian reserve relative to peers of the same age group. Keep in mind that ovarian reserve will gradually decline for everyone – it’s the timing and pace of change that differs. 

For example, in younger women, a higher number of antral follicles (small fluid-filled sacs containing immature eggs) and lower levels of certain hormones like FSH may be considered within the normal range. However, as a woman ages, it is expected that the number of antral follicles will decrease and hormone levels, such as FSH, may increase.

While age is a significant factor, other individual factors should also be taken into account when interpreting ovarian reserve results. Factors such as medical history, previous fertility experiences, underlying medical conditions, and fertility goals play a role in assessing the overall fertility potential. These additional factors can influence the interpretation of ovarian reserve results and help guide fertility treatment decisions tailored to the specific needs of the individual.

What causes decreased ovarian reserve?

Decreased ovarian reserve can result from various factors, including:

• Age: As we age, the quantity and quality of eggs naturally decline. The aging process gradually reduces the quality of eggs and ovarian reserve, making it more challenging to conceive.
• Smoking: Cigarette smoking has been linked to a higher rate of diminished ovarian reserve. Chemicals in tobacco smoke can accelerate the depletion of eggs and negatively impact ovarian function.
• Cancer treatment: Some cancer treatments, such as chemotherapy and radiation therapy, can have damaging effects on the ovaries. These treatments may cause a decrease in ovarian reserve and compromise fertility.
• Pelvic Surgery: Surgical procedures involving the ovaries or other pelvic organs can inadvertently damage or remove ovarian tissue. This can lead to a decrease in ovarian reserve and potentially affect fertility.
• Autoimmune diseases: Certain autoimmune conditions, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, can impact ovarian function and diminish ovarian reserve.
• Genetic conditions: Certain genetic disorders, such Fragile X syndrome, and other chromosomal abnormalities, can be associated with decreased ovarian reserve. These conditions may affect the development and function of the ovaries.

While these factors are known to contribute to diminished ovarian reserve, individual experiences vary. You may have none of the above conditions, and still face premature ovarian failure (POF). Or you may have one of the above factors, and have no problems at all getting pregnant. Sometimes, it just comes down to luck.

What does it mean if I have a high ovarian reserve?

A high ovarian reserve refers to a situation where there is an abundant number of eggs in the ovaries. While ovarian reserve naturally declines with age, certain factors can contribute to a higher ovarian reserve in some people.

One factor associated with a high ovarian reserve is younger age. Those in their 20s and early 30s generally have a higher number of eggs compared to those in their 40s, resulting in a larger ovarian reserve. Additionally, genetic factors can influence ovarian reserve, and some may have a naturally higher number of follicles and eggs in their ovaries.

Another factor that can contribute to a higher ovarian reserve is polycystic ovary syndrome (PCOS). PCOS is a hormonal disorder that can lead to the development of multiple small follicles on the ovaries. Those diagnosed with PCOS often have a higher number of immature follicles in their ovaries, which can translate into a higher ovarian reserve.

While a high ovarian reserve can be advantageous for fertility, it does not guarantee successful conception or a higher chance of pregnancy. Other factors, such as egg quality and hormonal balance, also play significant roles in achieving pregnancy.

At-home ovarian reserve tests

There are at-home options for ovarian reserve testing. However, keep in mind that most fertility doctors will want to re-do these tests. So taking a test at home, may mean paying for a test twice.

Here are some options:

• Natalist Women’s Fertility Test ($149) measures 5 hormones: estradiol, LH, FSH, TSH, and total testosterone. You can save 20% with code COFERTILITY20
• LetsGetChecked Ovarian Reserve Test ($139) measures 1 hormone, AMH. You can save 25% with code COFERTILITY25

Ovarian reserve and egg freezing

Ovarian reserve plays a significant role in the process of egg freezing, also known as oocyte cryopreservation. Egg freezing involves the retrieval and freezing of your eggs for future use, preserving your fertility potential at a younger age. 

Assessing ovarian reserve before undergoing egg freezing is crucial for determining the quantity of eggs available for freezing. Those with a higher ovarian reserve generally have a greater number of eggs suitable for freezing, increasing their chances of successful future pregnancy. 

On the other hand, those with diminished ovarian reserve may have fewer eggs available for freezing, necessitating careful consideration of the potential outcomes and options. Understanding your ovarian reserve provides valuable information to help guide the egg freezing process and optimize the chances of achieving successful future pregnancies when the frozen eggs are thawed and used in assisted reproductive techniques.

One of the key factors in determining whether egg freezing is a viable option is the level of a hormone marker for ovarian reserve, called Anti-Mullerian Hormone (AMH). In this article, we will discuss what AMH is and how (if at all) it is correlated with the number of eggs you can expect to have retrieved during egg freezing.

First off, what is AMH?

Anti-Müllerian Hormone (AMH) is a hormone that is produced by the granulosa cells in the ovarian follicles. The level of AMH in your blood is used as an indicator of your ovarian reserve, or the number of eggs remaining in your ovaries. Generally, the higher the level of AMH, the greater the number of eggs you have in your ovaries. Conversely, a lower level of AMH suggests a lower ovarian reserve. Since females are born with a fixed number of eggs, this number naturally declines over time. 

Does AMH tell you how many eggs you have?

Your AMH level corresponds to how many eggs you have (your ovarian reserve), but it can’t tell you the exact number of eggs. That being said, AMH levels have been shown to be a good predictor of ovarian reserve and response to fertility treatment. There are other factors such as age, overall health, and genetics that can also affect the number and quality of eggs. So while AMH can be a useful tool in assessing your fertility, it should not be the only factor considered when making decisions about fertility treatment.

Does AMH predict the number of eggs you will retrieve?

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. 

Is AMH correlated with the number of eggs retrieved during egg freezing?

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:

‍

AMH and egg freezing

As we’ve covered, AMH can be used as an indicator of ovarian reserve and response to fertility treatments like egg freezing. While AMH cannot tell you the exact number of eggs you have, studies have shown that it can be used as a predictor of egg quantity, which is crucial for the success of egg freezing. 

The relationship between AMH levels and the number of eggs retrieved during egg freezing is positive, with higher AMH levels generally indicating more eggs retrieved. However, there are other factors that can affect the number and quality of eggs produced, including age, overall health, and genetics. Thus, while AMH can be a useful tool in assessing fertility, it should not be the only factor considered when making decisions about fertility treatment. 

Freeze your eggs with Cofertility

Regardless of your AMH level, we’d love the opportunity to support you on your egg freezing journey. 

Through our 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. 

Through 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. 

By making egg freezing easier and more accessible, our programs further strengthen the American Society of Reproductive Medicine (ASRM)’s Committee Opinion that egg freezing can help promote social justice and strengthen gender equality.

If you don’t know your AMH and you’re interested in getting it tested as a baseline assessment, reach out and we’ll share next steps.

People come into the doctor’s office often with concerns that they may never be able to have children, either because of their age or because of their lab results. The result they are usually referring to is their anti-Müllerian hormone (AMH) test. When an AMH comes back less than promising, people get anxious real quick.

But a single hormone level can never tell you that you can or cannot get pregnant. There is more to fertility than a person’s hormone level or their age, though the two are important. Let’s dig deeper into AMH and age and what they can really tell us about fertility. 

What is AMH?

An AMH test is a simple blood test commonly used to assess ovarian reserve. Ovarian reserve is defined by the National Cancer Institute as “the total number of healthy, immature eggs in the ovaries” but I find this to be a bit misleading. Let me explain why.

AMH is released by antral follicles, which are small, fluid-filled sacs in the ovaries that each contain a single oocyte (immature egg). Your AMH level is positively correlated with the number of antral follicles you have in your ovaries. Simply stated, the more follicles you have, the higher your AMH level typically is. 

The actual number on an AMH report is typically a single digit number that, again, corresponds to the number of healthy follicles you have but it isn’t the actual total number in your ovaries if we were to count them. For example, an AMH of 3.5 does not mean you have 3.5 follicles. It does mean that you likely have the expected number of healthy follicles in your ovaries and we expect that each of those follicles contains an egg that has the potential to lead to pregnancy. And since AMH is thought to be stable throughout the menstrual cycle, it’s considered to be the best lab indicator we have for a person’s reproductive potential (in combination with age). 

What AMH is actually very good at is predicting the timing of menopause. Research shows that AMH becomes very low or undetectable about five years before menopause. Other research has shown that the time of menopause may be predicted with a mathematical model using only one AMH value and the age of the patient. 

TL;DR? Your actual AMH number is not the total number of healthy follicles (with eggs in them) that you have, but it does correspond to your overall ovarian reserve, or your reproductive potential based on the number and quality of eggs you have. AMH is actually a better predictor of the timing of menopause, since it becomes very low or undetectable about five years beforehand.

AMH and age

So how does AMH relate to your age? ​​In younger people, a gradual increase in AMH levels is seen from the first day of life. Maximum levels are reached in the teenage years and they stay pretty steady until around the age of 25. After that, AMH and age are inversely correlated, meaning that as a person gets older, their AMH goes down. Additionally, the rate at which someone’s AMH goes down varies from person to person so it’s impossible to guess where someone’s AMH will be in the future.

What is a normal AMH for my age?

Unfortunately, there is no international standard for AMH levels. However, some studies have tried to assess AMH levels and create models for what is considered normal for specific ages. One study looked at the median AMH levels (in ng/mL) in 2,741 participants. Their results are listed below:

• Under 25 = 5.13
• 25 = 5.42
• 26 = 4.91
• 27 = 4.12
• 28 = 4.96
• 29 = 3.87
• 30 = 3.53
• 31 = 3.59
• 32 = 3.44
• 33 = 2.70
• 34 = 2.49
• 35 = 2.58
• 36 = 2.28
• 37 - 1.85
• 38 = 1.66
• 39 = 1.72
• 40 = 1.27
• 41 = 1.26
• 42 = 1.20
• 43 = 0.81
• >43 = 0.72

If you have a lower or higher AMH than the numbers above going into your 30s or 40s, I encourage you not to freak out! Remember that these are medians, which means many people have AMH levels above or below them. Multiple studies have shown that AMH doesn’t correlate with how likely you are to get pregnant. In fact, one study looked at AMH, FSH, and inhibin B levels and tracked people for a year. They found that there was no correlation between someone’s ovarian reserve and their ability to conceive and that a low ovarian reserve was not associated with lower fertility. As a result, they did not recommend the use of FSH or AMH levels to “assess natural fertility.”

Lastly, It’s also important to keep in mind that the interpretation of AMH levels is laboratory assay-dependent. This means it can be different from lab to lab and test to test. Your provider should give you the reference range for their specific lab. If you get your AMH tested in one lab and then get it tested at another lab later, let your provider know before comparing those numbers. 

Is AMH or age better at predicting egg quality?

Based on the research, AMH levels alone probably do not accurately reflect egg quality. Though, when AMH is combined with age, it can be a better indicator than when it’s used alone. There is unfortunately no single test or number that can tell you with certainty how likely you are to get pregnant.

Age, on the other hand, has been proven by countless research studies to be one of the biggest determinants of egg quality. As a person ages, their eggs are more likely to become aneuploid, meaning they’re “genetically abnormal.” This can lead to difficulties with both getting and staying pregnant (i.e, higher risk of miscarriages). Once a person reaches their mid to late thirties, research shows that the quality and quantity of eggs declines rapidly. 

Unfortunately, there’s not a lot we can do about aging or about the decline in AMH that goes with it. However, it does no good to stress about either of these numbers. As stated earlier, AMH and age are each just one value your provider looks at to assess your overall reproductive potential. Neither value alone can completely predict your chances of conceiving naturally and neither defines your fertility.

Is AMH or age better at predicting how many eggs will be retrieved during egg freezing?

A lower ovarian reserve can mean fewer eggs are retrieved during egg freezing. This means both age and AMH factor into the success of an egg freezing or IVF cycle. 

Research has found that AMH is a good predictor of the response to ovarian stimulation and the number of eggs retrieved, regardless of a person’s age. 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. This is a great example of how age and AMH can both impact fertility.

At what AMH level should I freeze eggs? 

So when should you consider freezing your eggs? Honestly, the sooner the better. There is no specific AMH level at which you have to freeze your eggs. However, we know AMH only goes down as a person gets older, so the earlier you’re able to freeze your eggs, the better your response to the medications will be and, hopefully, the more eggs you’re able to have retrieved to keep your options open later.

When thinking about your AMH, these general guidelines for AMH values (ng/mL) and egg retrieval can be helpful:

• AMH <0.5 = predicts difficulty getting more than three follicles to grow in one egg retrieval cycle (this in turn reduces the chance for pregnancy with IVF)
• AMH <1.0 = suggests a limited egg supply and a short window of opportunity to conceive
• AMH 1.0 - 3.5 = suggests a good response to ovarian stimulation
• AMH >3.5 = suggests an ample egg supply (also indicates that your doctor may need to be cautious in order to avoid ovarian hyperstimulation syndrome (OHSS), a possible complication of ovarian stimulation)

So can you still freeze your eggs if your AMH is low? The simple answer is yes, you can. But you will be more likely to need more than one cycle to reach the ideal number of eggs.

You are not a number

With all the nuances involved here, it’s important not to get lost in the weeds. Fertility is impacted by so many factors that you can drive yourself crazy trying to manage all of them. Remember, you are more than any number. 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 it may look like. 

Freeze by Co is here to help you every step of the way on that journey. Our Split program allows people between 21 to 34 years old to 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. In the Keep program, you’re able to freeze your eggs and keep them all for yourself, on your timeline. In addition, you’ll have access to our online support community, the Nest. This valuable resource lets you engage with other people freezing their eggs at the same time! 

Whatever your journey looks like, our team is here to guide you through it and keep your family-building options open.

The AMH (anti-mullerian hormone) test is just one of many tests you may get when seeking answers about your fertility. But we know you’re not about to head to the doctor’s office for a blood draw without understanding what you’re getting yourself into. So here’s the full scoop on what to expect.

The lowdown on the AMH test

Think of the AMH blood test as a peek into a woman’s ovarian reserve. Here’s how it works: The AMH hormone is secreted by follicles in the ovaries. As you may know, follicles are the beginnings of human eggs, and a woman only has a finite number of eggs—the number of eggs decreases with age. This test measures the level of AMH in your blood.

“A higher level of AMH correlates to a higher ovarian reserve, or as we say, ‘the more gas left in the tank,’ says Dr. Joshua Hurwitz, MD, senior physician and partner at Reproductive Medicine Associates of Connecticut (RMACT).

About those eggs...

Unfortunately, women with a lower ovarian reserve may retrieve fewer eggs during egg freezing, so understanding your ovarian reserves is an important step in informing yourself and your doctors about what’s going on in your body. That way, you can make the right plans for you, depending on your goals.

Probably the most common reason to have an AMH blood test is as part of a fertility evaluation for any female patient interested in egg freezing or IVF, says Dr. Hurwitz. Any woman who’s trying to understand her future fertility potential could decide to have her AMH levels tested as well. In other words, you also might want to get the AMH blood test if you fall into any of these categories:

• You’re considering becoming an egg donor
• You might be freezing your eggs
• You’re thinking about getting pregnant and want to know if there’s a reason to act quickly

This isn’t like looking into a crystal ball. While having a normal ovarian reserve gives you a snapshot of what your fertility looks like now, it’s not a guarantee for what will happen in the future. Still, the results could help a woman more confidently decide to wait to try to become pregnant, or to freeze her eggs for potential use in the future, says Dr. Hurwitz.

What AMH do I need to freeze my eggs?

Research has found that AMH is a good predictor of the number of eggs retrieved during egg freezing, independent of age. Because of this, a fertility doctor will use your AMH levels (amongst other biomarkers) to determine the drugs and dosages during the procedure. 

In general, says Hurtwitz, patients can interpret their AMH level this way:

• 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

But know that a very high level of AMH could be a sign of polycystic ovary syndrome (PCOS), which may require specific fertility treatment and/or medications. When AMH is over 5.0 nanograms per deciliter, for example, Dr. Hurwitz says it’s worth addressing if there are other potential signs of PCOS. Also, FYI: younger women tend to have higher AMH levels, and older women tend to have lower AMH levels.

What AMH do I need to donate my eggs?

If you are looking to donate your eggs, minimum AMH requirements may be slightly higher. For example, with Cofertility’s Split program, we require a minimum AMH of 2.0, though clinics may have their own unique requirements. This is to increase the chances of retrieving enough eggs to actually split, to ensure positive outcomes for both parties involved.

AMH as part of a full work-up

It’s important to know that the AMH really isn’t a one-and-done test. It’s often done as part a full fertility evaluation, which may also include:

• Hysterogram (a.k.a. Sonohystogram or SHG), an ultrasound in which saline is added to the uterus (sort of a weird sensation but not so bad), so doctors can see inside and identify any problems with the uterus or fallopian tubes.
• Semen analysis, a test of a male partner’s sperm that gauges sperm count, as well as motility (the way they move) and morphology (size, shape and structure). Guys are so lucky this is their only major test.
• Hysterosalpingogram (HSG), an X-ray of the uterus and fallopian tubes (with a liquid dye in your bod!), which also can help identify or rule out certain problems.

In fact, the AMH probably isn’t the only ovarian reserve test you’ll get. It’s often done alongside:

• FSH blood test, another blood test. This is used to measure a different hormone called the Follicle Stimulating Hormone. FSH is released at the beginning of the menstrual cycle, so you’ve got to have your blood drawn at day 2, 3, or 4 of your period. A high level of FSH is associated with low ovarian reserve, and a low level of FSH is associated with a normal ovarian reserve.
• Basal Antral Follicle Count, an ultrasound in which the doctors will count the number of follicles they can see. The more follicles, the greater the ovarian reserve.

A woman’s age is also a huge factor in ovarian reserve and is really the most accurate way of gauging the quality of the remaining eggs, says Dr. Hurwitz.

It’s painless (mostly)

Since this is just a low-key blood test, there’s really not much to worry about. It can be done at any time during your menstrual cycle, and you don’t need to prep for it by fasting or in any other way. Think of it like getting a blood draw at your annual physical. You’ll have blood taken as usual through a needle into a syringe, and a Band-Aid will be placed on the site. Then, you’ll be able to go about your day as normal.

Dr. Hurwitz says his patients usually receive their AMH test results within a few days up to about a week, and they’re given over the phone by a nurse who can answer any questions they may have about their AMH levels. Then, after all their initial testing is done, the doctor sits down with his patients and discusses the results of all their tests to give a 360-degree picture of their fertility status. 

Plotting your next steps

AMH level alone won’t tell you what your next steps will be. If you’ve had all the ovarian reserve testing done, there isn’t anything further that needs to be measured in that regard.

Remember, AMH level should never be the sole measure of a woman’s fertility. In fact, one recent Journal of the American Medical Association study found that AMH levels didn’t predict which women would get pregnant over the course of a year. This is a reassuring sign for women who have low AMH levels, but Dr. Hurwitz notes that it doesn’t mean that the AMH test results aren’t important. They can help your doctor understand what’s going on in your body.

Taking your AMH results into consideration with all your other test results and health history,  you and your doctor will come up with a course of action. There’s no one answer for what this will be based on AMH level, but a low ovarian reserve might prompt a woman to begin egg freezing sooner.

Anti-Mullerian hormone (AMH) is a hormone produced by ovarian follicles. It is commonly used as a marker of ovarian reserve and can be measured in the blood. A high AMH level is often associated with polycystic ovary syndrome (PCOS), but it can also have other causes. In this article, we will explore what a high AMH result means and answer some common questions about AMH testing.

First off, what is AMH?

AMH is a hormone that is produced by the granulosa cells in the ovarian follicles. It plays a role in the growth and maturation of ovarian follicles in females. AMH levels are relatively stable throughout the menstrual cycle and can be measured in the blood.

AMH is commonly used as a marker of ovarian reserve, which is a rough number of eggs that a female has remaining in her ovaries. Since females are born with a fixed number of eggs, this number naturally declines over time. 

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.

If you are looking to donate your eggs, however, minimum AMH requirements may be slightly higher. For example, with Cofertility’s Split program, we require a minimum AMH of 2.0, though clinics may have their own unique requirements. This is to increase the chances of retrieving enough eggs to actually split, to ensure positive outcomes for both parties involved.

What AMH level is considered high?

In healthy females of reproductive age, higher levels of AMH mean that the ovaries have a larger supply of eggs. This means one would be expected to have better than average outcomes for egg freezing. 

Remember, there is no universal standard for AMH, so it can vary depending on the lab where the test is run. Your test results will include if your range is “normal”, “low”, or “high” and the cut-off can differ. For example, Atlanta Fertility considers over 4.5 ng/mL high. Advanced Fertility considers anything over 4.0 ng/ml high. While RMA would consider an AMH over  3.0 ng/ml as “very high”.

With high levels of AMH, you may be at higher risk for ovarian hyperstimulation syndrome (OHSS). This means your doctor may choose a specific protocol and/or do extra monitoring to decrease the risk of complications during egg freezing.

What AMH level is considered too high?

Again, this question depends on the lab. Your test results will come with a reference range, and will indicate if your number is high for your age. If your doctor considers your levels abnormally high and has concerns, they will discuss the results with you. 

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 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. 

Does high AMH always mean PCOS?

While an increase in AMH levels has been reported to be associated with PCOS, high AMH alone is not enough to diagnose PCOS. 

Not all patients with PCOS have high AMH levels, and not all patients with high AMH levels have PCOS. Diagnosis of PCOS requires a combination of symptoms, hormone levels, and imaging studies, such as ultrasound.

Does high AMH mean good egg quality?

Not necessarily. While a high AMH level is often associated with a larger number of ovarian follicles and eggs, 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.

Am I ovulating if my AMH is high?

AMH levels do not indicate if you’re ovulating or not. Ovulation is the release of a mature egg from the ovary and can be confirmed by monitoring the menstrual cycle and/or performing ultrasound studies.

Will I get a lot of eggs if I have a high AMH?

The success of egg freezing outcomes 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 doctor performing the procedure.

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.

One option to make egg freezing better is working with Cofertility. Through our 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. 

Through 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. It also enables access to exclusive guidance, free expertise, and community events. 

By making egg freezing easier and more accessible, our programs further strengthen the American Society of Reproductive Medicine (ASRM)’s Committee Opinion that egg freezing can help promote social justice and strengthen gender equality.

Summing it up

A high AMH level is generally a good sign for your ability to successfully freeze your eggs. But for some, it can also be one indicator of PCOS. While a high AMH level is often associated with a larger number of ovarian follicles and eggs, it does not necessarily mean that the eggs are of good quality (egg quality is more dependent on age). 

AMH levels are commonly used as a marker of ovarian reserve and can be helpful, in conjunction with other measures, in predicting the number of eggs that can be retrieved during an egg freezing cycle. However, it is important to keep in mind that egg quality is determined by several factors and cannot be measured directly by AMH levels. If you have concerns about your fertility or AMH levels, it is important to speak with a fertility doctor for personalized advice and treatment options.

Understanding reproductive health is crucial, especially when it comes to fertility. Anti-Müllerian hormone (AMH) is one of the key markers used to assess ovarian reserve, which refers to the quantity of eggs. Many factors can impact AMH levels, including age, genetics, and certain medical conditions.

One common question that arises is whether birth control, a widely used contraceptive method, can affect AMH levels. In this article, we will explore the relationship between birth control and AMH levels to shed light on this topic and provide valuable insights for those concerned about their fertility.

What is AMH?

Before delving into the impact of birth control on AMH levels, let's first understand what AMH is and its significance in assessing ovarian reserve. AMH is a protein produced by the small follicles in the ovaries. These follicles contain immature eggs, and the level of AMH in the blood provides an estimate of the remaining egg supply. Ovarian reserve tests can help you make decisions about egg freezing. In general, higher AMH levels indicate a larger number of follicles and potentially better ovarian reserve, while lower levels may suggest a diminished egg supply.

Can birth control affect your AMH levels?

One common concern among women is whether taking birth control can influence AMH levels. Birth control methods, such as oral contraceptive pills (aka “the pill”), patches, injections, and intrauterine devices (IUDs), work by regulating hormones and preventing ovulation. So it is reasonable to question whether these hormonal interventions can impact AMH levels.

Research suggests that hormonal birth control may affect AMH levels. But it depends on the type of birth control.

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 than for women who are not on contraceptives, with variation depending on the type of birth control

The amount of time you are on birth control may also be a factor. A systematic review of 15 studies concluded that AMH is unchanged in women using combined oral contraceptive pills if they were using it under six months. 

However, they found a lower AMH in long-term users of the pill. But it’s just temporary – AMH levels rebounded after they stopped using birth control.

Is AMH accurate if on birth control pills?

One study compared the AMH levels of 228 hormonal contraception users and 504 non-users. They found that users of birth control had 29.8% lower AMH concentrations. Because of this, the authors concluded that AMH may not be an accurate predictor for women using hormonal contraception.

You may want to consider the timing of the AMH test when using hormonal contraceptives. Estrogen can suppress the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are necessary for the development and maturation of follicles. 

As AMH levels are influenced by FSH and LH, you could wait for a few weeks after discontinuing birth control before measuring AMH levels for a more accurate assessment of ovarian reserve. Or, you could take the test knowing the results may be lower due to birth control. It’s best to discuss this with your doctor.  

Do I need to get off birth control to get AMH tested?

In general, it is not necessary to discontinue birth control before getting an AMH test. However, it's important to be aware that hormonal contraceptives, such as oral contraceptive pills, can potentially lower AMH levels temporarily while being used. This means that if you are currently using birth control, the AMH results may be lower than they would be if you were not on contraceptives.

If you are concerned about the accuracy of your AMH test or have specific fertility-related questions, it’s best to consult with a fertility doctor. They can provide personalized guidance based on your individual circumstances and help you understand how birth control may impact your AMH results. They will take into consideration factors such as the type of birth control you are using, your reproductive goals, and any underlying medical conditions. This will help ensure that you receive the most accurate and relevant information regarding AMH testing and its interpretation.

Will my AMH change if I get off birth control?

AMH can and will change throughout your life. And, it is generally believed that AMH levels should return to their baseline after stopping hormonal contraceptives. 

Birth control methods, such as oral contraceptive pills, work by suppressing ovulation and altering hormone levels. Once you discontinue birth control, your body will naturally resume its normal hormonal patterns, and AMH levels should stabilize accordingly.

Individual responses to stopping birth control may vary. Some may experience a temporary fluctuation in their hormone levels as their body adjusts, which could potentially affect AMH measurements. However, these fluctuations are typically short-lived, and AMH levels should gradually return to their baseline within a few menstrual cycles.

If you are planning to assess your ovarian reserve through an AMH test, you may want to wait for a few weeks or consult with your fertility doctor to determine the most appropriate timing after discontinuing birth control. This will help ensure a more accurate assessment of your current ovarian reserve without the influence of hormonal contraceptives.

Remember, AMH levels provide valuable insights into ovarian reserve but are just one piece of the puzzle when it comes to fertility. 

Does birth control help egg reserve?

Although birth control does not directly affect AMH levels or egg reserve, it can provide some indirect benefits related to reproductive health. By preventing ovulation and regulating menstrual cycles, birth control can help manage various gynecological conditions such as polycystic ovary syndrome (PCOS), endometriosis, and irregular periods. By providing symptom relief and controlling hormone levels, birth control can potentially improve overall reproductive health (thanks birth control!).

Additionally, certain forms of birth control, such as combined oral contraceptive pills, may help reduce the risk of ovarian cysts and decrease the incidence of ovarian and endometrial cancers. These benefits contribute to the overall well-being of your reproductive system, indirectly supporting egg reserve.

AMH and egg sharing

If you are looking to donate your eggs through Cofertility’s Split program, where you freeze for free in exchange for donating half to a family that could not otherwise conceive, we require a minimum AMH of 2.0 (though clinics may have their own unique requirements). This is to increase the chances of retrieving enough eggs to actually split, to ensure positive outcomes for both parties involved.

You are not a number

With all the nuances involved here, it’s important not to get lost in the weeds. Fertility is impacted by so many factors that you can drive yourself crazy trying to manage all of them. 

Remember, you are more than any number. 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 it may look like. 

Cofertility is here to help you every step of the way on that journey. 

Our Split program offers women a chance to freeze their eggs for free when donating half the eggs retrieved to a family who cannot conceive otherwise. If you qualify for the program and decide to donate half of your retrieved eggs, every expense associated with the egg freezing procedure —  medications, supplements, travel if necessary, insurance, and 10 years of storage — are completely free of charge. We don’t even need a payment or credit card up front, as the family you match with covers all the expenses.

Or, in our Keep program, you can freeze and store your eggs for your own future use, with lower prices on things like storage and medication – as well as our team’s support and access to our community.

The benefits for of working with Cofertility include:

• Power of choice: Freeze your eggs more affordably or, if you qualify, freeze for free when you give half to a family who can’t otherwise conceive.
• Community: Our inclusive online spaces allow you to connect with others going through the process in our private online community.
• Compassion: We’ll always treat you with care, and our Split program gives you the opportunity to make someone’s family building dreams a reality.
• Data-driven: We provide you with trustworthy guidance and evidence-based research so you can make informed decisions about your fertility.
• Free egg freezing: Freeze and store your eggs for 10 years, entirely for free if you qualify for our Split program.

Summing it up

Understanding reproductive health is crucial, especially when it comes to fertility. AMH is a key marker used to assess ovarian reserve, which refers to the quantity eggs. While birth control does not directly impact AMH levels or egg reserve, it can have temporary effects on AMH measurements while being used. The type and duration of birth control can influence the degree of impact on AMH levels. 

If you are currently using birth control, it is not necessary to discontinue it before getting an AMH test. However, it's important to be aware that hormonal contraceptives can potentially lower AMH levels temporarily. This means that the AMH results may be lower than they would be if you were not on contraceptives. Consulting with a fertility doctor can provide you with specific guidance on timing and interpretation of AMH results.

If you decide to discontinue birth control, AMH levels should return to their baseline over time as your body adjusts to its natural hormonal patterns. Temporary fluctuations in hormone levels may occur, but these are typically short-lived, and AMH levels should stabilize within a few menstrual cycles. (And if you do discontinue birth control, definitely use backup contraception during that period if you’re trying to avoid pregnancy). 

Remember, AMH levels provide valuable insights into ovarian reserve, but they are just one piece of the puzzle when it comes to fertility. Consulting with a fertility doctor can help you understand the broader context of your reproductive health and provide guidance on any concerns or questions you may have.

As a potential egg donor, you may be wondering about the qualifications, including if there’s a minimum AMH (Anti-Mullerian Hormone) levels. Understanding this hormone and its significance is critical in the egg freezing and donation process, especially if you're considering donating your eggs through an egg share program like the one offered by Cofertility. Let's delve into these important topics.

What is AMH anyway?

The Anti-Mullerian Hormone, or AMH, is a hormone secreted by the cells of developing egg sacs (follicles) within the ovaries. AMH levels are often used as an indicator of ovarian reserve, which means the quantity of eggs that are available for fertilization. The hormone plays an important role in fertility care as it provides insights into ovarian function and the potential to produce viable eggs during egg freezing.

AMH testing is a common part of the fertility workup as it helps doctors understand more about your ovarian reserve and ability to retrieve eggs that can be successfully fertilized. It is important to note that AMH level is not a measure of egg quality, but of quantity, and its level remains fairly constant throughout the menstrual cycle, which makes it a good measure for predicting ovarian reserve at any time. 

What AMH do I need to donate my eggs?

Through our 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. 

What is egg sharing?

Our unique model allows you to donate your eggs while also preserving half for your own future use. This can be an advantageous option for those who want to help others by donating their eggs, but are uncomfortable with other egg donation programs.

We believe egg sharing balances the interests of the donor and the recipient. It opens up opportunities for families seeking to conceive via donated eggs while respecting the donor's potential future family planning needs.

Egg donation with Cofertility

At Cofertility, we are striving to be the best place to be an egg donor (or what we call, a Split Member). We offer a supportive and transparent process that empowers donors to make informed decisions about their egg donation journey.

With our innovative approach, donors get to keep half of the eggs retrieved, plus:

• Free storage of their own eggs in cryopreservation for up to 10 years
• Coverage of all medical costs for the egg donation process
• Connection to the Cofertility community for support all along the way and after too
• The ability to work with the intended parents to decide together what your relationship will look like

If giving your eggs to intended parents sounds like something you would like to do, you may be able to qualify for the free egg freezing process and have your donation process covered too.

Take our quiz to see if you qualify for Split!

We believe that every donor deserves to have a positive and empowering experience, and we are committed to making that a reality. That’s why Cofertility was named one of the Best Egg Donor Programs by Egg Donor Connect.

Summing it up

Understanding your AMH level is a crucial part of the egg donation process as it provides an indication of your ovarian reserve, thereby shaping your egg freezing journey.

While an AMH level above 2 ng/ml is ideal for egg donation, it's important to remember that it's not the sole determinant of your eligibility. The process is multifaceted, taking into account various factors, and everyone’s situation is unique.

At Cofertility, we’re here to guide you every step of the way. From understanding your AMH levels to navigating through the egg sharing process, our team of fertility experts is ready to assist you in making informed decisions about your reproductive health and fertility journey. Your contribution as an egg donor can change lives, including your own.

Embarking on the path of family planning is an exciting journey filled with hope and, often, uncertainty. One area that typically gives rise to a multitude of questions revolves around oocyte cryopreservation, commonly known as egg freezing. While this medical breakthrough has provided countless women with greater reproductive autonomy, it's still not a definitive guarantee of biological motherhood.

In this guide, we’ll try and answer one of the most common questions around egg freezing: the chances of live birth. 

From frozen eggs to baby

At every stage of the in vitro fertilization (IVF) process (which is technically what egg freezing is, plus embryo fertilization in a lab), there's a certain level of attrition. Some collected eggs may be immature, making them unsuitable for freezing. Others may not withstand the thawing process. When you’re ready to fertilize those eggs into embryos, they will not necessarily all fertilize, and some fertilized embryos may fail to mature into viable embryos suitable for transfer. Even embryos that reach the transfer stage might not be genetically normal. And those that are genetically normal may not result in a viable pregnancy or live birth.

As a result, egg freezing is better viewed as a way to increase your chances of pregnancy down the line, rather than an insurance policy or a surefire plan. It’s a path filled with potential, and definitely gives you greater optionality when you’re ready to  have kids, but — and we are always very transparent about this — there is unfortunately no absolute promise of a live birth at the end of the egg freezing process.

How many eggs should I freeze?

Given these complexities, a pressing question for many women is, “how many eggs should I freeze to increase my chances of having a baby?” The answer is nuanced and largely depends on two variables: the age at which the eggs are frozen, and how many children you want.

Unfortunately, the quality of eggs can't be assessed before fertilization is attempted, adding another layer of uncertainty to this equation. Still, we can provide an approximate guide based on averages, which can inform individualized counseling, treatment planning, and expectation management.

One study out of Harvard Medical School of 520 cycles found the chances of live birth varies based on age and number of eggs frozen (see chart below). This guidance is not precise, but offers an approximate benchmark to guide you through your fertility journey. 

How many eggs will I get?

Another common inquiry from patients is how many eggs are likely to be retrieved and preserved in a single egg freezing cycle. The good news is that this is fairly easy for fertility doctors to predict using two crucial measures: anti-Müllerian hormone (AMH) and antral follicle count (AFC).

AMH and AFC, both estimators of ovarian reserve, can provide an approximation of the number of eggs that can be retrieved from a stimulated cycle. For instance, an AMH level of 15 pmol/L (2.1 ng/mL) could predict a yield of approximately 12 to 18 eggs. Similarly, AFC's numerical value directly correlates with the number of eggs potentially collected in one cycle, with a rough ratio of 1:1. So if your fertility doctor counts 15 antral follicles during the transvaginal ultrasound, you could potentially retrieve 15 eggs in a single cycle (note this number could be lower or higher based on other factors).

Will I have enough eggs to share?

Cofertility’s Split program offers women a chance to freeze their eggs *for free* when donating half of the eggs retrieved to a family who cannot otherwise conceive. If you qualify for the program and decide to donate half of your retrieved eggs, every expense associated with the egg freezing procedure —  medications, supplements, travel if necessary, insurance, and 10 years of storage — are completely free of charge.

Since the number of eggs is predictable with AMH and AFC, we’re only able to accept people into the program if we are confident they would have enough eggs to “split”. 

Setting expectations 

You can look at the probabilities and hormonal indicators, but everyone’s egg freezing journey is unique. Age, health, lifestyle, and genetic factors can all play a role in your path to motherhood. Remember, egg freezing is a science, but it's not an exact one. The uncertainties are part of the process. And while the prospect of attrition can seem daunting, it's important to remember that every step forward is a step closer to the potential for success.

Navigating these complexities can feel overwhelming, which is why support and guidance are crucial. At Cofertility, our mission is to guide you through this journey, providing you with the necessary information, support, and encouragement to make the best decisions for your fertility future.

Although egg freezing can't offer guaranteed outcomes, it has undoubtedly provided hundreds of thousands of women worldwide with expanded options and increased flexibility in their reproductive timelines. By understanding the process's intricacies and setting realistic expectations, we can navigate this journey together, with optimism, resilience, and hope.

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.

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. 

More and more people in the US (and the rest of the world) are taking control of their reproductive health and fertility by choosing to freeze their eggs. Whether this is so they can focus on a career, get an insurance policy with coverage for treatments, or because of medical reasons, this has allowed people to delay having children until whenever they’re ready to start a family.

If you’re thinking about freezing your eggs, you probably have tons of questions. In this article, we’re going to focus on a very common question: “How can I increase my chances of success when I freeze my eggs?”

Factors that can affect egg freezing success rates

Before an egg freezing cycle

Let’s start by going through what specific things make a difference in your chances of success before you even freeze your eggs.

Age

Age has been proven by countless research studies to be one of the biggest determinants of egg quality. As a person ages, their eggs are more likely to become aneuploid, meaning they’re genetically “abnormal.” This can lead to issues with both getting and staying pregnant (i.e, higher risk of miscarriages). On top of that, as a person ages, the number of eggs their ovaries contain continues to decrease naturally. Once a person reaches their mid to late thirties, the quality and quantity of eggs starts to go down more quickly. While there is no “perfect” age at which to freeze your eggs, freezing them before you reach your late 30s is considered ideal. 

AMH level

Another important factor is your Anti-Müllerian hormone (AMH) level. This is a simple blood test that is commonly used to tell us a person’s reproductive potential based on the number and the quality of eggs they have left in their ovaries. AMH is released by antral follicles, which are small, fluid-filled sacs in the ovaries that each contain a single oocyte (immature egg). Your AMH level is positively correlated with the number of antral follicles you have in your ovaries. Simply stated, the more follicles you have, the higher your AMH level typically is. AMH naturally goes down as a person gets older until it reaches close to zero during perimenopause. While there is no international standard for what a normal AMH level is, some studies have tried to create models for what’s considered normal for specific ages. Check out this article to find out more about AMH levels at different ages.

Antral follicle count

Antral follicle count (AFC) is another number to be aware of before egg freezing. AFC is used in fertility assessments to estimate the number of developing follicles in someone’s ovaries at a specific point in the menstrual cycle using ultrasound. As mentioned before, the more follicles you have (the higher your AFC is), the higher your AMH level. And just like your AMH, your AFC will also naturally go down as you age. 

How these values affect your egg freezing success 

Unfortunately, there isn’t a lot that can be done about aging or about the decline in AMH and AFC that goes with it but there are a few things to know about how they affect your egg freezing changes. 

• Ovarian reserve assessment. Age, AMH and AFC all provide valuable information about a person’s ovarian reserve. In general, younger age, higher AMH levels, and a higher AFC are good indicators that you have a larger pool of potential eggs in the ovaries. This means that you’re more likely to produce more eggs during an egg retrieval cycle, which increases the chances of a successful egg freezing cycle.
• Response to ovarian stimulation. Part of the egg freezing cycle includes taking medications to stimulate the ovaries to develop multiple eggs at once (as opposed to just one during a natural, unmedicated menstrual cycle). The response to these medications can vary based on age, AMH, and AFC. People who are younger and those who have a higher AFC/AMH tend to have a better response and produce more mature eggs during the stimulation. This increases the chances of retrieving a larger number of high-quality eggs for freezing.
• Number of cycles. In some cases, people with a lower AFC and/or AMH may have to go through more than one egg freezing cycle in order to get an adequate number of eggs. This can get costly and time-consuming pretty quickly.
• Future fertility potential. The number and quality of frozen eggs affects the chances of having a successful pregnancy when the frozen eggs are later thawed, fertilized, and transferred during an in vitro fertilization (IVF) treatment. A higher AFC and AMH can mean a higher number of frozen eggs, which increases a person’s chances of success in the future. However, neither of these numbers is the end-all-be-all here. In fact, 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, especially for younger people.

Again, all three of these factors aren’t necessarily things you can change so it can be easy to get discouraged if your values aren’t where you want them to be. Remember that each of these is just one value your provider looks at to assess your overall reproductive potential. No value by itself can completely predict your chances of conceiving naturally or define your fertility. A comprehensive assessment of a person’s fertility potential has to be done by a fertility specialist before jumping to any conclusions and making decisions about fertility preservation.

During an egg freezing cycle

Now, let’s go through the factors during an egg freezing cycle that can affect your chances of success.

Quantity and quality of eggs retrieved

The success rates of egg freezing cycles are significantly influenced by both the number and quality of eggs retrieved. The number of eggs retrieved is important because it directly correlates with the chances of developing viable embryos after thawing. This is definitely a case of “more is more”--the more eggs that are successfully frozen, the higher the probability of having viable embryos when the time comes. 

However, the quality of the retrieved eggs is just as important. High-quality eggs have a better chance of surviving the freezing and thawing process than low-quality ones. So, as you can imagine, a cycle with lots of eggs that are all low-quality isn’t necessarily more successful than another cycle that produced less eggs but they’re all high-quality. 

As a result, fertility providers will always aim to maximize both the quantity and quality of the eggs retrieved. This is essential for improving  the success rates of egg freezing cycles so that, ultimately, we end up with healthier embryos and better chances of a successful pregnancy.

Type of freezing method used 

There are two main techniques used for freezing eggs: slow freezing and vitrification. The slow freezing method involves gradually lowering the temperature of the eggs, which allows ice crystals to form within the cells. This process can damage the delicate internal structure of the eggs, which can lead to lower viability and success rates once the eggs are thawed. In contrast, vitrification is a freezing process that solidifies the eggs quickly without forming ice crystals. This method protects the cell’s internal structures better and has been shown to increase post-thaw survival rates. This in turn, means higher success rates during IVF treatments. It makes complete sense, then, that vitrification has become the preferred way to freeze eggs.

Tips to increase egg freezing success rates

Alright, so now that we’ve established what’s important when it comes to egg freezing, what exactly can you do to maximize these factors for yourself? 

• Consider freezing your eggs at a younger age. There may not be much we can do about the fact that we’re all getting older but in terms of egg freezing, the general rule is that the younger you can do it, the better. According to the American Society for Reproductive Medicine (ASRM), the ideal time to freeze your eggs is in your 20s and early 30s, while you have more eggs and those eggs are healthier. So, whether you’re 25 or 35, your eggs today are still probably healthier than your eggs in one, five or 10 years!
• Optimize your fertility health before beginning the egg freezing process. 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!
• Consider using a different type of freezing method. Ask your fertility provider which method they plan to use when freezing your eggs. Vitrification is the more common method now given its improved outcomes when compared to slow freezing but it doesn’t hurt to confirm that this is the method your particular clinic uses.   
• 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 AMH level or AFC. If your fertility provider thinks more cycles will improve your chances, they’ll discuss those recommendations with you.
• Be particular about the clinic you choose. There are a ton of fertility clinics to choose from nowadays, so take the time to do some detective work and find one that works for your needs. If you know people who’ve used a fertility clinic, ask them for their honest opinions. Read reviews. Look up the providers’ credentials (usually listed on the clinic’s website). You can also find out the clinic’s success rates in terms of live births and other important statistics through their website. Schedule a couple consultations to compare your options. Make sure to come with questions and to actually ask them all. If you’re not sure what to ask, check out some suggestions here. 

Emotional considerations

It’s important that we take a second to talk about the emotional side of this experience. For many people, the decision to freeze their eggs is tied to hopes of preserving future fertility. When a lab test or a cycle doesn't yield the desired results, there can be feelings of hopelessness, frustration, sadness, anxiety, and uncertainty about future family planning options. On top of that, this isn’t a cheap or simple process! So there can be disappointment stemming from both the financial and physical investments that have been made. 

Because of all of this, seeking support and guidance throughout this process has to be a priority. Support from both loved ones and through professional counseling can make a huge difference when it comes to coping with the emotions you might be dealing with. 

Establishing clear and open communication with your fertility providers also plays a key part in helping people cope with the challenges that might come up. Your providers know the ins and outs of your particular situation so they’re the most qualified to tell you what you need to prioritize (and what you can ignore) to improve the success of your egg freezing cycle(s).

With all the nuances involved here, it’s important not to get lost in the weeds. Fertility is impacted by so many factors that you can drive yourself crazy trying to manage all of them. Remember, you are more than any number. 

Conclusion

To recap, there are several different factors that can affect the success of an egg freezing cycle including your age, AMH level, AFC, the number and quality of eggs retrieved, and the type of freeing method used. Some of these, you don’t have control over. For the ones you can control, there are a few things you can do. 

Optimizing your fertility health before the egg freezing process, freezing your eggs at a younger age, doing more than one cycle, and using a safer freezing option are all ways that you can improve your chances of a successful freezing cycle. This process can be so overwhelming— focusing on the things that you can control can help you feel more grounded throughout your fertility journey.

In addition, you’ll have access to our online support community, the Nest. This is a valuable resource that lets you engage with other people freezing their eggs at the same time!

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.
