How Egg Freezing Success Rates Vary by Age

Women throughout the United States are taking control of their reproductive health and fertility by opting to freeze their eggs. Egg freezing has allowed women to delay having children until they’re ready to start a family. Women decide to freeze their eggs for many different reasons—delaying motherhood to focus on their careers, access to an insurance policy with coverage for treatment, medical necessity, and more. If you’re considering freezing your eggs, you likely have many questions, one of which being, “What are my chances of getting pregnant when I’m ready to use my frozen eggs?”

There are many factors that can impact egg-freezing success rates, but the most significant is age. Studies have shown that the older women are when they freeze their eggs, the probability of getting pregnant later on decreases. The overall number of eggs a woman has, and the quality of those eggs diminish over time. In fact, the proportion of euploid (normal, healthy) embryos goes from about 76% among 25 to 30-year-olds to 52% among 35 to 40-year-olds. That percentage drops significantly after age 40. That means that double or even triple the typical number of eggs need to be retrieved to achieve similar success rates, but even then, those success rates continue to dwindle.

When it comes to your fertility health, knowledge is power. Egg freezing is often not top of mind for women in their twenties, but understanding how age impacts success rates can help women of all ages make the right decision for their fertility.

How to Improve Egg Freezing Success Rates

Older women need to freeze many more eggs than women in their early twenties to have the same chances of a successful pregnancy. A study by FertilityIQ revealed that “Women who stored 10 eggs after the age of 35 had a 30% success rate. Women under 35 with the same number of eggs had twice that success rate. That’s a big step up, and we’re not done. For women under 35 who managed to bank not 10 eggs, but 20 eggs, their success rate jumped to 80%.”

Egg Freezing vs. Embryo Freezing

Another option associated with a higher success rate than freezing eggs is to fertilize the embryos and freeze them. However, this option is most suitable for women who are in long-term relationships or are married. That way, they can start building their family with their partner when they’re both ready.

How You Can Afford Treatment

If cost is a barrier to treatment, we can help you find the best path forward. Egg freezing is covered in part by fertility insurance in some states, but increasingly employers are offering it for free as a benefit to their employees. Be sure to check with your employer and your insurance company to determine whether egg freezing is covered by insurance. At the Fertility Centers of New England, we make egg freezing affordable. A complete cycle of monitoring, egg retrieving, and freezing the eggs costs $6,500; this includes all treatments except for medication.
