Egg freezing can provide amazing reproductive optionality in the event that you may need to use your frozen eggs to have children down the line — but what happens to unused frozen eggs if you don’t end up needing them? In this article, we’ll discuss what happens after you freeze your eggs and some options for what to do with any unused frozen eggs. 

Because it can be beneficial for anyone with ovaries to freeze their eggs — we offer a program to freeze your eggs for free through our Split program, when you donate half of the eggs retrieved to another family who can’t otherwise conceive. Our hope is that whenever you’re ready to start trying for a baby, you’ll be able to get pregnant unassisted. That being said, with 1 in 6 individuals experiencing fertility challenges, egg freezing allows you to be a little bit more prepared, just in case. 

Once you freeze your eggs, there are various paths you can decide on in the future, whether or not you choose to use them. Let’s dive in. 

What are the chances I’ll need to use my frozen eggs? 

As we mentioned, fertility challenges are — unfortunately — not entirely uncommon. Again, our hope is that your experience trying to conceive, whenever you’re ready, is easy-breezy. But that just may not be the case, which is why we’re on a mission to make egg freezing more accessible, empowering, and positive for all. 

It's an especially valuable option for those who know they want to build a family, but know they might need to use IVF down the line. This includes single moms by choice and members of the LGBTQ+ community, who often rely on assisted reproductive technologies to achieve their family-building dreams.

If you do end up wanting to use those eggs in the future, that involves: 

• Shipping them from storage
• Thawing them
• Fertilizing them into embryos in a lab (otherwise known as IVF, or in vitro fertilization)
• Letting those embryos develop for several days, with the option to have them genetically tested
• Transferring an embryo into your uterus or that of a gestational carrier to hopefully develop into a live birth 

The data on frozen egg thawing

It’s a relatively straightforward process, but given that egg freezing was only recently popularized, there’s not a ton of long term data around how many people end up needing to use those eggs in the future. We do have some data around thaw rates, as the success of thawing frozen eggs is not guaranteed. One study from 2009 found that the overall survival rate of eggs from vitrification (the most commonly used method of egg freezing today) was 95%. 

A 2023 UK-based study followed a cohort of 167 women that underwent 184 social egg freezing cycles between January 2006 and March 2022, and showed that 16% of the women have returned to use their frozen eggs so far. That statistic, however, should be examined with a grain of salt — the biggest reason being that if someone froze her eggs as late as 2022, the odds of her moving forward with IVF only one year later may be unlikely. 

Another 2022 study led by experts at NYU Grossman School of Medicine and the NYU Langone Fertility Center looked at 15 years of frozen egg thaw outcomes. Of 543 women, 61% moved forward with at least one embryo transfer. While this doesn’t tell us exactly how many women thawed their eggs, it was likely greater than 61%, assuming that some of these eggs unfortunately either didn’t survive the thaw or didn’t fertilize into embryos.

What happens if I *don’t* use my frozen eggs? 

Before you move forward with egg freezing, you’ll sign a contract with your clinic (or long-term storage facility), where you state your preferences about what to do with your eggs if, at any point, you decide not to move forward with fertilization and transfer. Don’t worry — you can always change your mind later on. 

If you don’t end up needing your frozen eggs, or decide down the line that you don’t want to keep them in storage for any reason, here are your options.

Unused frozen eggs option #1: discard them 

If you know you don’t want to keep storing your frozen eggs, and would rather not pursue other options (listed below), you can always request that the clinic or storage facility dispose of them. 

Unused frozen eggs option #2: donate them to science 

The biggest reason why egg freezing technology has made so much progress over the years is because of individuals volunteering to provide reproductive material for research. The ability to study frozen eggs and embryos, along with the medications, techniques, or devices used among various cycles can help improve success rates for others pursuing fertility treatment in the future. 

If you don’t see this listed in your initial contract but want to pursue this as an option, ask your clinic if this is possible.

Unused frozen eggs option #3: keep paying for storage

Frozen egg storage fees will vary depending on the location of the storage facility, the time you’re willing to commit to storage (some facilities offer discounts for bulk pricing — say, paying for 5 years upfront), transportation fees, and more. Typically, this ranges between $500 - $1,500 per year. 

As part of the free egg freezing provided through Cofertility’s Split program outlined above, you’ll receive 10 years of frozen egg storage. And of course, you can always remove, thaw, or ship them somewhere else before those 10 years are up if you’d like. After all, they’re your eggs! And if you’re working with a good clinic in the US using vitrification methods (and don’t mind paying storage fees), you can even store your frozen eggs indefinitely. 

Unused frozen eggs option #4: donate them to another family

Many individuals or couples — including LGBTQ+ families, those with infertility, or cancer survivors — may rely on egg donation in order to grow their families. If you’re interested in pursuing egg donation, talk to your clinic. You’ll need to undergo some screening to see if you qualify, but this could be an incredible option. 

Conclusion 

If you’re not 100% certain you won’t be using your frozen eggs and you are comfortable with the storage expense, our recommendation is to continue storing your eggs until you’re sure you no longer need or want them. You never know. 

If you have not yet begun the egg freezing process and you are interested in more affordable (even free) egg freezing, take our quiz to see if you qualify for Cofertility’s Split program. It only takes a minute!

• What to Look For in an Egg Freezing Clinic

Thanks to advancement in reproductive technology, egg freezing can offer women the opportunity to preserve their fertility while they focus on other aspects of their lives. But what if they have pursued their education, advanced in their careers, and are happily settled with their forever person, when life takes a left turn? Significant life changes such as divorce may also prompt women to consider egg freezing as a way to preserve their fertility for future family-building purposes. This option may allow them the time needed to heal without feeling pressured to rush into finding a new partner and give them the space to make informed decisions about their future.

The emotional impact of divorce

Divorce or a breakup can be an incredibly challenging and emotionally taxing life event. The end of a relationship can bring about feelings of loss, grief, loneliness, and uncertainty. Divorce can impact various aspects of one's life, including future plans— plans that may have included children. A divorce or breakup can raise concerns about future fertility issues, especially for women over the age of 35. 

How egg freezing works, and how much it costs

The process of egg freezing typically begins with ovarian stimulation where the woman undergoes hormonal treatments to stimulate the ovaries. The goal is to produce multiple eggs in one cycle as typically only one egg is produced in a cycle. Once the eggs have reached maturity, they are retrieved via an out-patient procedure where a thin needle is inserted into each follicle, and the eggs are retrieved. Once retrieved, the eggs are cryopreserved using vitrification, a rapid cooling technique. The frozen eggs are then stored in cryogenic tanks until they are ready to be used.

There are a few factors that determine success rates. By success rates we are referring to a live birth outcome using the frozen eggs. Generally, women under 35 have better outcomes and the more eggs retrieved, the higher the likelihood of success. A recent study found that irrespective of age at freezing, a significantly high live birth rate was achieved when the number of eggs frozen per patient was 15 or more. 

The process of freezing eggs can cost anywhere from $10,000 to $20,000 and above. Costs include things like the initial consultation and testing, ovarian stimulation and egg retrieval, the egg freezing procedure, medication, and storage fees. Once the eggs are ready to be used, there are costs involved for thawing and then fertilizing to create embryos. After that there are fees for embryo testing and the transfer. If a sperm donor is used, there are various costs involved with that as well.

Learn more about our Split program, where qualified women can freeze their eggs for free when donating half to a family that couldn’t otherwise conceive. 

Navigating the decision-making process

Egg freezing allows women to take control of their fertility and help them make informed decisions about their reproductive future, with or without a partner.  However, there is still some concern about whether those who choose this option will regret their decision, especially given the costs involved. This article looks at several studies that explore this idea of regret. Overall, it was surmised that the only regret most had was they wished they had done it sooner.

Deciding to freeze eggs after a breakup or divorce can be a complex and personal decision. So it is important to feel and process emotions, seek support when needed, and make decisions that feel right for you and your future goals. It is understandable that following a breakup or divorce, there may be uncertainty about future relationships. So the decision to freeze eggs may involve deciding how to move forward with one's fertility independent of a partner. 

It’s also normal to have mixed feelings about the decision to freeze eggs, including relief at having a plan in place for the future but also sadness about the circumstances that led to the decision, and anxiety about the unknowns ahead. So it is very important to find healthy ways to manage stress and anxiety during this time. Which includes self-care, self-compassion, and leaning on support systems.

As important as it is to plan for the future, it is also important to keep in mind that plans always evolve over time. So I encourage you to remain flexible. Be prepared to adjust plans as  circumstances change. For example, at what point will you consider a sperm donor? If you find a new partner will you use frozen eggs or will you try to get pregnant on your own? If you do  get pregnant without using the frozen eggs,  what happens to the frozen eggs? Do they remain stored for a certain period of time? Are they donated? Or are they disposed?

Summing it up

Divorce or a break up brings about significant life changes, including changes in family planning. Freezing eggs provides a way to preserve fertility options for the future, allowing individuals to take time to decide on family planning when they're ready, whether it's with a future partner or as a single parent. It also allows individuals to focus on their emotional healing without feeling rushed into making decisions. By offering a way to preserve fertility and extend the window for family planning, egg freezing has become a valuable option for women navigating life changes.

The gift registry has been a cultural institution for pivotal life moments — from the gilded spoons and Ninja blenders of wedding registries to the cute little onesies of baby shower lists. These wish lists give friends and family an easy way to provide support that you actually want. 

But what if we took this concept and applied it to another life milestone that is also super exciting? This brings us to the idea of an egg freezing registry. Yes, you heard that right. An egg freezing registry.

On Sex and the City, after celebrating countless weddings and babies, Carrie Bradshaw famously took matters into her own hands and created her own registry in honor of her marriage to herself. Her registry had just one item — a pair of Manolo Blahnik shoes. Our take? If Carrie can celebrate herself, you can, too. Especially when you’re doing something so incredible for your future as freezing your eggs. 

Why you deserve an egg freezing registry

You may be wondering, particularly in a society that still wrestles with norms surrounding reproductive choices, as to whether you “deserve” to have a registry for something as personal and medical as egg freezing. The answer is a resounding YES, and here’s why.

Normalizing reproductive autonomy

Creating a registry for egg freezing can help normalize the conversation around reproductive autonomy and shatter persisting taboos. Women have long been subject to societal pressures about when and how they should have children. The ability to crowdfund one’s egg freezing process (or at least get some goodies covered) is a bold statement of agency, positioning the egg freezer not as a subject of societal expectations but as an architect of her own life.

Creating a registry for egg freezing can help normalize the conversation around reproductive autonomy and shatter persisting taboos.

Solidifying social support

The explicit act of creating a registry — and having loved ones contribute to it — serves as a profound endorsement of your choices. The communal act of contributing to a registry can offer emotional sustenance and make sure you know that your community is invested in your well-being, present and future.

Lessening the financial load

Financial obstacles should not dictate reproductive choices. Just as registries for weddings or baby showers are widely accepted tools for “getting someone started” with the essentials, an egg freezing registry is a legitimate way to help offset some of the costs.

A reimagined social contract

Finally, having an egg freezing registry reinforces a modernized social contract. At its core, a registry is an agreement among a community that signifies its collective investment in a significant life event. Weddings are not just about the couple, and baby showers are not just about the parents; they are about a larger circle of family and friends who will interact with that couple or child and want to support and celebrate them. Similarly, an egg freezing registry proclaims that a woman's reproductive choices are worth communal support, thus redefining the very ethos of what our social contracts can include.

So, do you deserve to have an egg freezing registry? Absolutely. In doing so, you're not only giving yourself the gift of choice but also expanding the societal dialogue around what choice can and should look like.

What should I add to my egg freezing registry?

One of the most exciting possibilities of an egg freezing registry is the potential to ask for specific add-ons that could aid in your egg freezing journey. Here are some ideas:

• Nutritional supplements: Omega-3s, prenatal vitamins, and other supplements to prepare your body for your cycle.
• Heating pad: Useful for post-procedure comfort and relief from cramps.
• Fuzzy socks: These make the often-cold clinic rooms and stirrup-bound procedures markedly more comfortable.
• Chocolates/other treats: Emotional well-being is part and parcel of the egg freezing journey; indulgent treats can serve as small but potent morale boosters.
• Wellness packages: Sessions for acupuncture or fertility yoga, aimed at enhancing both emotional and physical well-being.
• Books and journals: Literature on reproductive health, fertility journeys, or self-reflective journals.
• Travel vouchers: For those who choose clinics far from home, these can cover transportation or even lodging costs.
• Food delivery/meal prep: Gift cards to services like Doordash, Uber Eats, HelloFresh, Goldbelly, can help keep you well fed during the egg freezing period. 
• Bath bombs: For pre- or post-procedure relaxation, because a soothing bath can be a sanctuary in stressful times.
• Other relaxation aids: Consider adding aromatherapy oils, scented candles, or a premium-quality eye mask for deep relaxation.

You’ll want to diversify the options on your registry to make it easier for contributors to select gifts that align with their budget and your needs. These practical and comfort-focused gifts not only provide material relief but also serve as tokens of emotional support from your community.

Tips for hosting and sharing your egg freezing registry

So where could you host such a registry? Existing platforms could easily be adapted for this purpose. A few possibilities include:

• Amazon: Given its almost universal reach and diverse product range.
• Target: A favorite for baby shower registries, the leap to egg freezing isn't a big one.
• GoFundMe: Already a popular choice for medical crowdfunding, this platform could provide a natural fit if you just need cash.
• Meal Train: Makes it easy for friends and family to help feed you!

Spreading the word about your egg freezing registry

Creating the registry is the first half of the equation; sharing it with your network is the other, equally nuanced, half. The act of disseminating your egg freezing registry becomes not just an invitation for contributions but also an opening for dialogue, education, and emotional connection. 

Much like sharing any significant life news, timing is pivotal. You may want to inform the closest people in your life individually before broadcasting it more broadly. 

When you share your registry, include a personalized message explaining why you've chosen to freeze your eggs and how their support can be instrumental. This humanizes what might otherwise seem like a straightforward transaction, adding layers of meaning and context.

We recommend emphasizing that you appreciate any support or celebration and that there is zero pressure to contribute. There are multiple ways to show support, be it emotional or material. This may be especially helpful to include, as some recipients may be financially constrained or morally conflicted.

As your journey progresses, keeping your contributors updated adds an extra layer of engagement and acknowledgment. It’s an opportunity to show the impact of their support, which goes beyond monetary contributions and enters the realm of emotional sustenance.

Creating an egg freezing registry is more than a logistical step; it’s an emotional and sociocultural undertaking that can serve various roles: a litmus test for societal progress, a platform for dialogue, and an arena for collective emotional investment. Navigate it with the same sensitivity and thoughtfulness you applied when deciding to freeze your eggs in the first place, and you can open up spaces not just for communal contributions but for meaningful human connections as well.

Freeze your eggs with Cofertility

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.

The human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the United States. In fact, according to the Centers for Disease Control and Prevention (CDC), HPV is so common that “nearly all sexually active men and women get the virus at some point in their lives.” With at least 150 types of HPVs that we know of, it’s no wonder that 79 million Americans have at least one type. But fear not! 

While it’s true that some STIs can lead to infertility, there’s no need to freak out in the case of HPV. HPV on its own shouldn’t affect your ability to conceive. However, because HPV is often asymptomatic (meaning there aren’t any obvious signs or symptoms), it’s also one of the least treated STIs. Most of the time, that isn’t a big deal. But depending on the type of HPV someone has, there can be an increased risk of developing cancer or precancerous cells on the cervix, which do require treatment. The treatments to remove these abnormal cervical cells can, in turn, affect fertility—this is when discussing fertility if you have HPV becomes really important so let’s talk about it.  

What is HPV and what causes it?

We’re gonna back up for a second here and explain the basics of HPV. HPV is actually an umbrella term for a group of over 200 related viral infections that affect the outer skin layers of the genitals, mouth, hands and feet. So, while transmission can happen without sexual intercourse, the vast majority of HPV infections are the result of unprotected sex.

In these cases, you can get HPV by having vaginal, anal, or oral sex with someone who has the virus but it’s most commonly spread during vaginal or anal sex. It also spreads through close skin-to-skin touching during sex. A person with HPV can pass the infection to someone even when they have no signs or symptoms.

Because of this, if you’re sexually active at all, you can get HPV—even if you’ve had sex with only one person. You can also develop symptoms years after having sex with someone who has the infection. This is why doctors usually can’t tell you when you might have gotten it.

Types of HPV and treatments

Of the many types of HPV, only some are of actual concern and could therefore affect fertility, either due to the virus itself or the treatments used to manage it. Low-risk HPVs mostly cause no disease and typically go away on their own within 2-3 years. However, a few low-risk HPV types can cause warts on or around the genitals, anus, mouth, or throat. High-risk HPVs can cause several types of cancer. There are about 14 high-risk HPV types including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. Two of these, HPV16 and HPV18, are responsible for most HPV-related cancers.

As mentioned earlier, most HPV infections don’t cause cancer. Your immune system is usually able to control HPV infections so they don’t progress to cancer. However, high-risk HPV infections are more likely to persist and can eventually cause cervical cancer. In these cases, the immune system is not able to control the HPV infection and as the high-risk HPV infection lingers for many years, it can lead to abnormal cell changes that, if untreated, may worsen over time and become cancer.

If your doctor decides that they need to remove abnormal cells, they’ll use one of the following treatments:

• cryotherapy, or freezing and eliminating the abnormal tissue
• a cone biopsy (conization) to remove part of the cervix
• a loop electrosurgical excision procedure (LEEP), which involves removing cells with a wire loop that has an electrical charge

We’ll talk more about how these procedures can affect your fertility later on.

How does HPV impact fertility?

While most HPV infections clear up on their own (and rarely make themselves known through noticeable symptoms), the infections that persist can have a negative impact on fertility for all genders—either due to the infection itself or the treatments used.

Fertility risks associated with HPV include:

• Damage to the cervix via HPV itself or the treatment used to remove affected tissue from the cervix
• Decreased ovarian reserve
• Damage to sperm or parts of the male reproductive system

HPV and cervical function

First and foremost, HPV can damage the cervix directly over time if left untreated. This is why it’s so important to get those annual exams and routine pap smears with HPV testing! Most of the time, testing is the only way to know for certain whether a person has HPV or not. Once HPV has persisted for a long time or is getting more severe, it’s time to remove abnormal cells with one of the procedures mentioned earlier–cryotherapy, cone biopsy, or a LEEP. These procedures can most notably affect your ability to reach full term in a future pregnancy but this depends on several factors including how large and deep the area to be treated is.

In all cases, cell removal can change your body’s cervical mucus production. The procedures may also cause stenosis, or a narrowing of the opening of the cervix. This can slow down sperm and make it harder for an egg to get fertilized. Cones and LEEPs can also cause the cervix to weaken. While this won’t cause infertility or difficulty getting pregnant, it can lead to cervical insufficiency, which can cause your cervix to painlessly open and thin before your pregnancy has made it to term, and lead to a preterm delivery.

HPV and ovarian reserve

There have been several interesting studies about HPV and ovarian function but overall the literature is a bit of a mixed bag. Overall, research has suggested that HPV infection may be associated with a higher rate of spontaneous loss or underdevelopment when undergoing IVF. One study that compared HPV positive and HPV negative people found that a decreased ovarian reserve was more common in the HPV positive over the HPV negative group. Another study looked at HPV positive and HPV negative people undergoing IVF and their response to stimulation. No significant difference was seen in the responsiveness to controlled ovarian stimulation in terms of the number and maturity of retrieved eggs or in terms of fertilization rates. Finally, a recent study published this year showed no effect on live birth rates when comparing people with and without HPV.

HPV and its effects on male partners

Several studies have shown a link between HPV and decreased fertility for male partners. In particular, sperm containing HPV has been shown to negatively contribute to both male and couple infertility. One study done in 2011 found that men who had HPV were more likely to have an impairment of certain sperm parameters, like motility. This was confirmed in another study done in 2015. On top of that, if sperm containing HPV fertilizes an egg, there may be an increased risk of early miscarriage.

Can I freeze my eggs if I have HPV?

The good news with all of this is that an HPV diagnosis alone should not affect your ability to get pregnant or to freeze your eggs. Most fertility specialists will require an up to date pap smear and HPV test as part of their evaluation and you’ll usually be allowed to continue with the freezing process as long as the HPV is low-risk, since those cases are expected to clear on their own.

If you do have a high-risk HPV, you’ll need to discuss those results with both your OB/GYN and your fertility doctor to figure out what next step is right for you. Depending on the specific HPV strain, if there are any lesions and how advanced they are, your doctor will recommend continuing with egg freezing or delaying until after treatment. 

If there are precancerous cells in the cervix, minor treatment through cryosurgery or LEEP will be necessary and this is almost always recommended before trying to get pregnant or undergoing any other fertility treatments, including egg freezing or IVF. For the most part, these procedures don’t affect reproductive potential though and most people go on to have healthy pregnancies once they’ve recovered.

Risks and benefits of egg freezing with HPV

The main risk of freezing with HPV is the concern for a lower yield and the quality of eggs retrieved. As mentioned before, some studies have shown that HPV does have an effect on ovarian reserve but others have shown little to no differences in IVF outcomes. There are also so many additional factors that affect a person’s fertility. Your provider is going to be the best person to tell you whether your case warrants clearing the HPV before moving ahead with egg freezing. The benefit of egg freezing with HPV is that you’re taking a proactive step to preserve your future fertility. Whether your HPV is low- or high-risk, whether you require treatment or not,  you’ll know you’ve safeguarded your options.

Can I donate eggs if I have HPV?

The donor egg screening process will vary somewhat from clinic to clinic but here at Cofertility, our goal is to be as clear as possible about what this involves. All potential donors will be assessed in terms of their age, AMH levels, medical and family history, psychological and physical health. Making sure your pap smear and HPV testing are up to date is included in this process. 

HPV won’t automatically disqualify you from becoming an egg donor since it’s not transmittable through your eggs. However, as mentioned before, this will depend on which HPV type, whether it’s low or high-risk, and whether there are any precancerous or cancerous lesions found during the screening process. For a full list of disqualifications for egg donation through Cofertility, click here. 

Conclusion

The takeaway from all of this at the end of the day is that preventive care is king! Protecting yourself from HPV by getting vaccinated and making sure to get your pap smears on time can not only decrease your cervical cancer risk (which is a pretty good reason all on its own) but it can also lower your risk for preventable pregnancy or fertility concerns down the road. 

While there’s still more research to be done on the effects of HPV on fertility in all genders, it can safely be said that discussing HPV and fertility with your healthcare providers should be at the top of your list. This is especially true if you have HPV and end up requiring more invasive management—your providers can help you make a plan about your fertility future before any treatments begin.

Egg freezing and HPV can be confusing individually so you’re not alone when it comes to questions and concerns around both topics and how they affect each other. Freeze by Co is here to help you every step of the way. With our Split program, people between 21 to 33 years old have the chance to freeze their eggs for free! After 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 or not interested in donating half the eggs retrieved, you can still participate in the Keep program up to age 40. You would be able to freeze your eggs and keep them all for yourself, on your timeline while having access to an additional valuable resource in our support community. Our private, online community allows you to engage with other people freezing their eggs at the exact same time! 

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

One of the most commonly asked questions we hear from people considering freezing their eggs is if they’ll gain weight during the process. Hey, we get it — it’s a fair question, and while there have been tons of advancements in the egg freezing process, there’s still lots of misinformation out there about it all. Through a comprehensive exploration of the egg freezing process, hormonal shifts, medications, and lifestyle aspects, we’re here to set the record straight about weight gain and egg freezing. 

A closer look at the egg freezing process

Before we jump into potential weight implications of the egg freezing process, it’s essential to understand what that process actually entails. Egg freezing revolves around controlled ovarian stimulation, which basically means taking daily hormonal medications for about 10-12 days to stimulate your ovaries to produce more eggs than usual in a single cycle. Right before you ovulate, when those eggs are at peak maturity, a reproductive endocrinologist will retrieve those eggs while you’re under anesthesia. 

In egg freezing, mature eggs are collected, frozen, and stored for your own potential future use, whereas in egg donation, the retrieved eggs are contributed to assist those who need help from an egg donor to grow their family — including gay dads, those with infertility, cancer survivors, and more. Whether you’re freezing your eggs, donating them, or both via our Split program (where you freeze for free when donating half), the stimulation process may cause concerns about potential weight changes due to hormonal shifts and medications. If this is you, you’re in the right place, and we’ll explain it all.

Dispelling weight-related myths: the what and the why

While scientific studies about this subject are limited, most fertility doctors say that, while some weight gain can be a side effect during the egg freezing process, it is unlikely for noticeable weight gain to persist beyond the retrieval cycle. It’s possible to experience slight weight fluctuations during the retrieval cycle, but these changes are typically attributed to factors like temporary fluid retention and abdominal bloating rather than significant fat accumulation. 

Not everyone experiences weight change during the egg freezing process (you could actually lose weight if you’re stressed about the experience for one reason or another and don’t have an appetite), but for those who do, it is not usually substantial or enduring.

Egg freezing medications

Some of the medications involved in your egg freezing protocol can also play a role in minor weight changes. The controlled ovarian stimulation process involves the administration of hormonal medications, primarily follicle-stimulating hormone (FSH), and luteinizing hormone (LH). These medications are crucial for encouraging your ovaries to develop more mature eggs during that cycle. But because these medications can influence appetite and metabolism regulation, this could lead to small weight fluctuations. 

Once you stop taking these medications, any fluctuations resulting from temporary fluid retention will likely dissipate, and these effects are generally transient. 

Lifestyle factors and their impact

Beyond medications, lifestyle factors also play a role in potential weight fluctuations during an egg freezing cycle. But regardless of your weight, we want you to feel your best throughout your egg freezing cycle. 

Nourishing your wellbeing

Egg freezing or not, a well-balanced diet rich in nutrients supports your body's overall functioning. Incorporating whole foods, lean proteins, whole grains, fruits, and vegetables fosters a sense of wellbeing and provides energy throughout the egg freezing process. But in addition to helping you feel good, eating a balanced diet may have a positive impact upon your egg freezing cycle itself. And certain foods rich in specific nutrients may actually impact your egg quality.

Rest and stress management

Ensuring adequate rest is vital during the egg freezing journey. Your egg freezing medications may influence your energy levels, underscoring the importance of listening to your body's cues. Stress can also influence weight fluctuations (in either direction), making stress management an essential aspect of wellbeing during the egg freezing process. 

Prioritizing rest allows your body to recover, and if you’re trying to maintain a stable weight, it can help support that. Our recommendation? Block off some time, load up on shows to watch, plan some cozy nights, and take egg freezing as an excuse to just chill (if you can). Your egg freezing cycle might also be the perfect time to finally download that meditation app you’ve been planning to try.

Egg freezing and BMI

While we’re on the subject of weight gain and egg freezing, you may be wondering if your weight itself plays a role in predicting your cycle outcomes. There’s a lot of conflicting research out there about this, but when it comes to egg donation in particular, fertility clinics often do have BMI limitations in place. For egg freezing, you may be subject to similar BMI requirements as set out by clinic partners, but it is typically more flexible than if you are donating eggs to another family. 

The more you know

To sum it up — yes, sometimes people gain a little weight during the egg freezing process (and other times they lose a little weight). But it’s usually not a noticeable change given how the egg freezing cycle lasts under two weeks. If you have specific concerns related to weight gain during egg freezing, we encourage you to consult with your fertility doctor who can provide personalized guidance based on your weight and health history.

As you think through your options, we encourage you to explore our quiz to see which of our accessible egg freezing programs you may qualify for. 

With our Split program, members who qualify based on clinic criteria can freeze their eggs entirely for free when they donate half to a family that can’t otherwise conceive.

Through our Keep program, members self-fund their egg freezing journey and keep the entire egg yield for themselves, with discounts and support from our team every step of the way.

With both programs, members also get exclusive access to our members-only community, where they can connect with others going through the egg freezing and donation processes at the same time and lean on each other for support and encouragement.

As women, we are often tasked with making complex decisions about our bodies, our health, and our future. Among the myriad of choices, one of the most significant is the decision of whether or not to freeze our eggs. But once you've made the decision and plan to go through the process, you now may be wondering, "What exactly happens to my eggs after I freeze them? Where do they go? How long can they remain frozen?"

Egg freezing, also called oocyte cryopreservation, offers a chance to focus on other stuff now while planning for your future family. But how does it work, and what happens to your precious eggs once they are safely frozen? Let's delve into this fascinating, sometimes bewildering world of fertility preservation.

The egg freezing process: a quick recap

Before we venture further, let's refresh our understanding of the egg freezing process. It starts with hormone injections that stimulate your ovaries to produce multiple eggs. These eggs are then retrieved through a minor surgical procedure, and once retrieved, they are immediately frozen in a state-of-the-art laboratory. Following the retrieval and freezing process, your eggs are stored in a secure and carefully monitored cryo-storage facility. 

Egg freezing and preservation

Vitrification is a newer and more effective method of freezing eggs that has largely replaced older methods such as slow freezing. With vitrification, eggs are quickly frozen using a high concentration of cryoprotectants and then plunged into liquid nitrogen for storage. This process creates a glass-like state that preserves the eggs in a nearly perfect condition. In fact, vitrification ensures a very high rate of survival of the eggs, typically 95% or above.

Compared to slow freezing, which can damage the eggs and reduce their viability, vitrification has a higher success rate of producing healthy embryos for later use. It has become the preferred method of egg freezing for most fertility clinics and has allowed more patients to successfully preserve their fertility.

If you have any doubts about your clinic, you can ask them what type of method they use for egg freezing. It's important to do your research and choose a reputable fertility clinic with experience in vitrification if you're considering egg freezing.

Long-term storage and monitoring

Once the eggs are frozen, they are stored in liquid nitrogen. Some clinics keep those frozen eggs stored at an onsite lab, but in most cases they are shipped to an offsite facility. As soon as you’re ready to use them, they can be safely shipped back. 

In either case, the frozen eggs' care doesn't end at storage. They are monitored regularly to ensure the liquid nitrogen levels remain constant, and the facility's temperature control and security systems are working correctly. A well-maintained facility prioritizes meticulous record-keeping, tracking the storage duration and any other pertinent details about each egg. 

Cofertility members can take advantage of our partnership with TMRW Life Sciences, a fertility technology company that has developed the world's first automated solution for storing and managing frozen eggs and embryos. 

TMRW's technology platform digitally identifies, tracks, monitors and stores patients' frozen eggs and embryos with safety, accuracy, efficiency and transparency. TMRW's platform sets a new standard of care by reducing potential points of failure by 94% compared with manual systems.

So what is TMRW doing differently? 

• Digital labeling - instead of handwritten labels, TMRW uses digital labeling and RFID tracking. With this tracking system, clinics always know exactly where your eggs and embryos are and can easily find them when you’re ready to use them.
• Automated management - instead of relying on manual processes, TMRW has a new fully-automated digital system that helps eliminate 94% of potential failure points
• Real-time inventory - TMRW has gone the extra mile by creating a 24/7 cloud-based monitoring system with real-time inventory updates to provide new levels of safety, transparency, and peace of mind. 
• Active monitoring - TMRW provides 24/7 digital monitoring (thousands of daily checks!) and expert human oversight to identify potential issues before they become a problem.

Will my eggs survive the thaw?

Several factors can impact the success of egg thawing, including your age when the eggs are frozen, the number and quality of the eggs, the technique used to freeze the eggs, and the quality of the clinic’s laboratory. 

The quality of the eggs is also a crucial factor in egg thawing. Good quality eggs have a higher chance of survival and fertilization. However, even with good quality eggs, there is no guarantee of success, and the process may need to be repeated to achieve pregnancy.

If and when you decide to use them

When you decide the time is right to use your frozen eggs, they are thawed in the lab using a warming solution. 

But keep in mind that thawing is just the first part. The eggs will then need to be fertilized with sperm and grown into embryos. The surviving eggs are then fertilized using a process called intracytoplasmic sperm injection (ICSI), where a single sperm is injected directly into each egg.

After fertilization, the resulting embryos are monitored for a few days as they begin to develop. The most viable embryos are then transferred to your uterus in a procedure similar to a pap smear. If successful, the embryo implants in your uterus and grows, leading to pregnancy.

Generally, the younger you are when freezing your eggs, the better the chances of success. Eggs frozen in your late 20s or early 30s have a higher chance of survival and successful fertilization compared to those frozen in your late 30s or 40s.

If you decide NOT to use them

What if, down the line, you decide not to use your eggs, or you have more than you need? 

One study of egg freezing patients at UCSF found that 89% believed they would be glad they froze their eggs, even if they never used them to conceive a child. So if you don't end up needing your frozen eggs down the line, there are a few options for what to do with them.

• Keep them in storage. Most storage facilities offer long-term storage options (our partnership with TMRW includes plans up to 10-years long), allowing you to keep your eggs frozen for as many years as  necessary. This may be a good option if you're not yet ready to use the eggs but want to keep them as a backup plan.
• Donate the eggs to someone else who may need them. Egg donation is a process of donating eggs to another person or couple who needs them, such as LGBTQ+ families or those suffering from infertility. This can be a wonderful gift for those who may not be able to have a child otherwise. If you go through our Split program, you will have already been cleared as a donor and can easily donate these additional eggs. If you’re not part of the Split program but think you may be interested in this down the line, talk to your doctor as they may be able to do some additional donor-related screening during your egg freezing process. 
• Dispose of them.  If you decide that you no longer need your frozen eggs and don't want to continue storing them or donate them, simply request that they are disposed of by the clinic or storage facility.
• Donate to science. Many research studies rely on donated eggs to investigate new techniques and treatments for infertility. Ask your clinic if this is an option.

Emotional considerations

Aside from the practical aspects, it's important to acknowledge the emotional journey involved in egg freezing. It's normal to feel a mix of emotions – relief, hope, anxiety, or even sadness. Know that these feelings are common and valid. Don't hesitate to seek support, be it from a trusted friend, family member, a professional counselor, or the Cofertility community.

Summing it up

The journey of your eggs from freezing to potential future use is complex and exciting, underscored by sophisticated science and meticulous care. Deciding to freeze your eggs can be an empowering choice, giving you autonomy over your fertility and future family planning. Knowing what happens to your eggs after freezing them can provide comfort and clarity as you navigate your fertility journey.

In the end, egg freezing is an investment in your future, offering an opportunity to expand your family when the time is right for you. It's a testament to the advancements in reproductive science and a tool for you to take control of your fertility. Trust in the process, seek support when needed, and above all, know that your choices are valid, and your feelings are heard. After all, the journey to parenthood, in whatever form it takes, is a voyage of hope, love, and extraordinary potential.
