Egg Freezing in the US: Which Clinics Offer It and How Common It Is

Egg freezing (oocyte cryopreservation) lets people store eggs to try for a pregnancy later. It begins like IVF: medication to stimulate the ovaries, then egg retrieval. But the eggs are frozen instead of fertilized right away.^[4] This guide uses CDC data to show how widely clinics offer it and how common fertility-preservation cycles have become.

Who offers egg freezing?

In the CDC’s 2022 data, 449 of 451 reporting clinics (99.6%) said they offer egg cryopreservation.^[1] In practice, almost every US IVF clinic offers it. States with the most clinics offering egg freezing:

State	Clinics offering egg freezing	Reporting clinics
California	84	85
New York	44	44
Texas	44	44
Florida	26	26
Illinois	20	21
New Jersey	14	14
Washington	12	12
North Carolina	11	11
Pennsylvania	11	11
Virginia	11	11

How common are fertility-preservation cycles?

The CDC counts cycles in which eggs or embryos were frozen for future use, rather than transferred, as fertility-preservation cycles. This includes egg freezing and embryo banking. In 2022, 9.2% of all ART cycles were for fertility preservation, roughly 40,059 cycles.^[1] The share has grown each year:^[1][2]

Year	Cycles for fertility preservation	Total ART cycles
2020	7.4%	326,471
2021	8.7%	413,776
2022	9.2%	435,426

By age

Age group	Share of cycles for fertility preservation (2022)
Under 35	10.5%
35–37	11.5%
38–40	8.6%
Over 40	4.7%

Fertility preservation is most common in the under-35 and 35–37 groups and least common over 40.^[1] This fits patient-education guidance that egg freezing tends to be more effective at younger ages, because younger eggs are more likely to be healthy.^[3]

Which clinics do the most egg freezing?

The share of a clinic’s cycles devoted to fertility preservation varies widely. The median reporting clinic devoted 4.6% of its cycles to it, and the middle half ranged from 2.3% to 9.6%.^[1] 51 clinics devoted 20% or more of their cycles to fertility preservation, which suggests a strong focus on egg or embryo banking.^[1]

States where fertility preservation makes up the largest share of the median clinic’s cycles:^[1]

State	Median clinic: cycles for fertility preservation	Clinics with data
California	12.1%	81
Colorado	8.8%	8
Washington	8.3%	12
Minnesota	7.9%	5
Maryland	6.8%	5
Virginia	6.7%	11
New York	6.6%	44
Georgia	5.2%	10

Every clinic page on FertilityList shows its fertility-preservation share in the “Practice patterns” table.

Egg freezing or embryo freezing?

Some people who want to preserve fertility freeze embryos rather than eggs. That means fertilizing the eggs first with a partner’s or donor’s sperm. Embryo freezing requires deciding on a sperm source at the time of freezing; egg freezing keeps that decision open. Both start with the same stimulation and retrieval process.^[4] The CDC’s fertility-preservation figure combines both, so it cannot show how many cycles froze eggs versus embryos.

Embryo freezing is also part of routine IVF: most transfers in the US now use frozen embryos (see frozen vs. fresh embryo transfer). The lab skills involved, freezing, storing and thawing, are shared, which is one reason nearly all IVF clinics also offer egg freezing.

Planning considerations

• Timing. A stimulation cycle typically takes about two weeks from starting medication to retrieval, and some people do more than one cycle to store more eggs.
• Medical reasons. People facing treatments that can affect fertility, such as some cancer treatments, may have time-sensitive decisions. Clinics often have fast-track pathways for them.
• Storage. Frozen eggs can be stored for long periods, but storage fees recur every year. Ask what happens to stored eggs if you move, stop paying, or the clinic changes ownership.

What the CDC data does not tell you

The CDC clinic data does not report success rates for eggs that were frozen and later thawed by the same patient. Many people who freeze eggs have not yet used them, so outcomes appear years later, if at all. Be cautious with any single “success rate” for egg freezing. Ask a clinic how many of its patients have returned to use frozen eggs and what happened.

Patient guidance from professional bodies notes that egg freezing does not guarantee a future pregnancy. The number of eggs frozen and the age at freezing both matter.^[3]

Questions to ask a clinic

1. How many egg-freezing cycles did you perform last year?
2. How many patients have returned to thaw their eggs, and what were their outcomes?
3. Based on my age and test results, how many eggs might I expect per cycle, and how many cycles might I need?
4. What does each cycle cost, including medication? What is the annual storage fee, and what happens if I move?
5. Which lab freezes and stores the eggs? Is it accredited? See SART membership and lab accreditation.

Bottom line

Nearly all US IVF clinics offer egg freezing, and fertility-preservation cycles are a growing share of treatment, especially before 38.^[1] National data on thaw outcomes is limited, so ask each clinic for its own experience.
