Egg Freezing Calculator

It depends on your age. One large clinic study suggests freezing 15 to 20 mature eggs under age 38, for roughly a 70% to 80% chance of at least one live birth, and 25 to 30 mature eggs at ages 38 to 40, for roughly a 65% to 75% chance.¹

Another study found that at least 8 to 10 mature eggs are needed for reasonable success, with numbers set case by case after age 36.² Egg freezing is not commonly recommended after age 38.³ Many people need two retrieval cycles to reach these numbers.

Egg freezing works best in your 20s to early 30s, and it is not commonly recommended after age 38.³ Eggs are healthier then, and you get more of them per cycle, so each egg is worth more.

But freezing too early can mean paying storage fees for eggs you never use. The number of eggs falls faster from age 35 to 40, so waiting costs you more eggs.³

It varies a lot. In one large study, women had an average of 8.9 eggs retrieved per cycle, and 6.7 mature eggs per cycle were frozen.² At ages 36 to 40 the averages were 8.8 retrieved and 6.6 frozen, and over 40 they were 5.1 and 3.9.²

Your AMH level and antral follicle count predict your number better than age alone.

There is no known time limit. Once eggs are frozen in liquid nitrogen at -196°C, all activity stops, so they do not age or break down.

Babies have been born from eggs stored for over 10 years, with the same success rates as eggs stored a short time. Some countries set legal storage limits, so ask your clinic about local rules.

In the United States, one cycle usually costs $10,000 to $15,000, plus $4,000 to $6,000 for hormone medicines. Storage adds about $500 to $1,000 per year.

Later, thawing the eggs, fertilizing them, and doing an embryo transfer costs another $5,000 to $10,000. If you need two retrieval cycles, double the first number. Some employers and insurance plans now cover part of the cost.

Embryos have slightly better survival and success rates, because they have already passed the fertilization test. Freezing eggs loses a few at thaw and a few more at fertilization.

But embryos need sperm now, from a partner or a donor, and they can raise legal issues if a relationship ends. Eggs keep all your choices open. If you have a partner you plan to have children with, embryos are a good option. If not, eggs are usually the better fit.

The shots sting a little but are done with tiny needles. The retrieval itself is done under light anesthesia, so you feel nothing, and it usually takes 15 to 30 minutes.³

Common side effects during the 10 to 12 days of shots are bloating, sore breasts, mood swings, and headaches. Cramping and spotting are normal for a day or two after retrieval. A serious reaction called OHSS (ovarian hyperstimulation syndrome) happens in about 1% to 5% of cycles, and modern protocols have made it much rarer.

No. Every month your body starts to ripen a group of eggs, and all but one normally die off. Fertility drugs simply rescue that whole group instead of letting them go to waste.

Egg freezing does not lower your ovarian reserve or bring on early menopause. You can still get pregnant naturally after freezing.

It can be, but expectations need to change. In one large clinic study, each egg retrieved at ages 38 to 40 led to a baby about 4.5% of the time, and at 41 to 42 about 2.5%.¹ So you may need 30 or more eggs for solid odds. Most 40-year-olds get fewer eggs per cycle, so that often means several cycles.

An AMH test and antral follicle count will tell you fast whether multiple cycles are realistic. Some people at this age choose embryo freezing or trying to conceive now instead.

Many people do. In one large study, women did an average of 1.5 egg freezing cycles each.² More than one cycle is more common after age 35 or with a low AMH.

Doing a second cycle back-to-back is safe and common. Ask your clinic for your mature egg count after the first retrieval, then compare it to your target number before deciding.

Yes. Thousands of births from frozen eggs have been tracked, and there is no rise in birth defects, chromosome problems, or growth issues compared with babies from fresh eggs or natural pregnancy.

The fast-freezing method called vitrification protects the egg from ice crystals, which was the main risk with older slow-freeze methods.

An AMH above about 1.5 ng/mL usually means a normal response and a decent egg haul. Between 1.0 and 1.5 is lower but still workable. Under 1.0 ng/mL often means fewer eggs per cycle and likely more than one cycle.

AMH predicts how many eggs you will get, not their quality. Age drives quality. A 30-year-old with low AMH still has better eggs than a 40-year-old with high AMH.

About two to four weeks once your cycle starts. The stimulation shots run about 10 to 12 days, with blood tests and ultrasounds to track how your ovaries respond.³ Expect 4 to 6 short monitoring visits. The retrieval happens about 36 hours after a final trigger shot.

Add a few weeks before that for testing, consults, and insurance approval. Most people take just one day off work for the retrieval and feel normal in a day or two.

Almost. Fresh eggs still have a small edge, because not every frozen egg survives thawing: in one clinic study, 86.1% of warmed mature eggs survived.¹ After that step, frozen eggs fertilized at about the same rate as fresh eggs, 70% against 72%.¹

The bigger factor is age. Eggs frozen at 30 and used at 40 behave like 30-year-old eggs, which is exactly why people freeze them.
