Egg Freezing

More people are waiting to start their families, whether to focus on careers, travel, or find the right partner—there’s no wrong reason to wait. Egg freezing allows you to pause your biological clock, giving you more flexibility and options for the future.

Why Egg Freezing?
Fertility Changes Over Time
Egg quantity and quality both decline with age. Freezing your eggs preserves them at your current age, increasing your chances of success if you need help getting pregnant in the future.
Flexibility and Peace of Mind
Egg freezing allows you to focus on your priorities—like career, travel, or finding the right partner—without feeling pressured by your biological clock.
A Sprint, Not a Marathon
Egg freezing is a focused, short-term process. In just a few weeks, you can complete the steps to preserve your eggs, giving you an empowering safety net for your future family plans.
The Process

How egg freezing works

01

Initial
Testing

Your initial consultation will take place on-site at your Open Fertility clinic. You’ll complete initial testing and then meet with your dedicated provider (sometimes virtually) to discuss your test results and learn more about the egg freezing process. This appointment will take about an hour, and you’ll have plenty of time to ask questions!
02

Treatment
Plans

The results from your initial visit will allow your provider to build a treatment plan and calendar that aligns with your schedule and goals.
03

Ovarian
Stimulation

If and when you decide to freeze your eggs, you’ll begin to administer hormonal injections (don’t worry, we’ll teach you how) in order to grow the eggs in your ovaries. We’ll monitor your ovaries’ progress during this time with transvaginal ultrasounds and bloodwork.
04

Egg
Retrieval

Once your follicles have reached maturity, you will be scheduled for your egg retrieval – a 20-minute outpatient procedure that will be done by a board-certified Reproductive Endocrinologist under general anesthesia. For this procedure, you will travel to our partner lab. Most patients take this day off and return to work the following day.
05

Storage

Your eggs will be safely stored at our partner lab until you decide you would like to come back and use them – there’s no expiration date!
Investment
Our patients deserve transparent, straightforward pricing. By simplifying the process, we offer great care at half the cost of other clinics.

Frequently Asked Questions

When should I freeze my eggs?

Everyone’s reproductive journey is unique, and the right time for egg freezing varies from person to person. While there’s no universal answer, it’s important to know that eggs are generally healthiest when women are in their mid-20s. At this age, women typically have the highest number of follicles and eggs with fewer chromosomal abnormalities, which is why most egg donor programs recruit women between 21 and 30.

Reproductive timelines also vary significantly—some women reach menopause around 51, while others experience their last menstrual period closer to 41. For younger women early in their careers, egg freezing may feel financially out of reach. However, it’s often more cost-effective to freeze eggs at a younger age, as fewer cycles are usually needed, and medication requirements are lower. In contrast, older women may need more cycles to achieve a similar result, which can make the process more expensive.

Will egg freezing affect my future fertility?

No, egg freezing does not impact your future fertility. The process of egg retrieval only takes a small portion of the eggs available in that cycle, leaving the rest of your egg supply unaffected. Similar to how birth control pills don’t extend or reduce fertility, egg freezing preserves eggs without changing your body’s natural reproductive potential.

How long can my eggs be stored?

Your eggs can remain frozen for as long as you need. Many women choose to try conceiving naturally first, viewing their frozen eggs as a backup plan. Others, especially those with known risk factors for infertility, may decide to use their frozen eggs as soon as they’re ready to start a family. Some women even turn to their frozen eggs when they’re ready to have a second or third child. There’s no “one size fits all” approach—your eggs will be there whenever you’re ready to use them.

Do I have to use my frozen eggs to get pregnant in the future?

No. Most women can get pregnant naturally and their eggs become a backup plan should they need it. We encourage you to think about how many children you want when freezing your eggs. Although it may be easy to get pregnant naturally the first time, depending how many children you want, consider freezing eggs for that second, third or fourth child (if that’s your desired plan).

Do I have to stop using birth control to freeze my eggs?

In most cases, no. You do not have to take out your IUD to go through egg freezing, and hormonal birth control pills will be evaluated based on your unique situation. If you are using the Nexplanon implant, we will ask you to remove it before starting the egg freezing process.

Doyle and Colleagues’ Results

Doyle and colleagues have reported the next largest data set to date, including live birth rates after warming 1,283 vitrified and subsequently warmed eggs between 2009 and 2015. This is one of the largest published data sets available. While not every embryo created from these frozen eggs was transferred, the authors estimated the live birth rates as if every viable blastocyst stage embryo was transferred. As a proxy for older patients who had fewer embryos, they used their success rates from their IVF outcomes – they had previously demonstrated that blastocyst stage embryos from frozen eggs had at least as high a pregnancy and live birth rate as blastocyst stage embryos from women of the same age using fresh, never frozen eggs.  Their published outcomes involved the below calculations:

  1. Calculate the number of live births from frozen eggs from women at various ages.
  2. They still had embryos (blastocysts) remaining from the frozen eggs that were not transferred and refrozen, so they estimated how many of those frozen blastocyst embryos would result in a live birth based on their experience with blastocyst stage embryos frozen from women of the same age (at the time the eggs were retrieved). This estimate allowed them to approximate the efficiency per egg.
  3. Since this number looked unrealistically high for women at age 41-42, they substituted the efficinecy of live birth per fresh oocyte at this age and applied this number to the eggs that survived freezing/warming.

This study lacked extensive data on eggs frozen from women who are older than 37 (only 96 eggs).  The 96 warmed eggs from women over age 37 yielded 5 babies. These numbers gave an unusually high efficiency for women over age 37 so the authors correctly adjusted their data to “predict” the efficiency using:

  1. Their survival rate for frozen eggs.
  2. The anticipated number of blastocysts that would develop from those eggs.
  3. Their live birth rates using blastocysts derived from fresh (non-frozen eggs) at each age group.

They then assumed a binomial “normal” distribution to yield the predicted probability per frozen oocyte at each age group. Our calculator uses the same assumption (a binomial distribution) to arrive at the probability of 1 or multiple children based on the number of eggs and the probability of a live birth per egg.

They arrived at the following estimates for live birth efficiency per egg:

Doyle et al 1,283 warmed eggs
<308.2%
<358.0%
35-377.3%
38-404.5%
41-422.5%

 

Cobo and Colleagues’ Results

Cobo and colleagues is the largest data set of published outcomes from frozen/warmed oocytes. This study simply reported on the live birth rate per warmed egg in women of each age group.  We entered these estimates into a binomial calculator to arrive at the chances of having 1 or multiple live births based on the number of eggs used in each age group.

Interesting additional information:  the majority of these eggs were not tested for chromosome number. This study further reports no difference in outcomes based on amount of time samples were frozen (up to five years).  90.4% of warmed eggs survived the thaw and 1.4% of warming cycles had no eggs survive. These data yielded the following outcomes (the number of eggs included is represented on the right column).
