Donor Egg Success Rates

Nationwide, donor egg success rates are higher than 50%

In assisted reproductive technologies, egg age matters. The age of the woman who produces the egg is closely related to whether or not that egg will fertilize, implant, and grow into a healthy baby.

According to the U.S. Centers for Disease Control and Prevention, as the age of a woman’s eggs increases, the percentage of embryo transfers that result in live births declines. Because egg donors are typically in their 20s, live birth rates with donated eggs are generally much higher, even when the woman carrying the baby is older.

The percentage of donor-egg embryo transfers resulting in live birth is consistently above 50%, according to the CDC. The age of the recipient is not related to the success of a donor egg cycle.

Donor’s age is key to donor egg success rates

Because they are young – egg donors typically respond better than older women to the medications that stimulate egg production. They often produce more good quality, genetically balanced eggs, and ultimately, better-quality embryos that are more likely to implant and grow into healthy fetuses.

In fact, donor egg success rates are so high, our Los Angeles fertility center typically limits the number of embryos transferred to reduce the possibility of a high-risk multiple pregnancy.

According to the CDC, of the 5,673 pregnancies resulting from use of fresh donor-egg embryos in 2013, about 32% were twins, 1% were triplets or more, and 61% were singletons. Our goal at USC Fertility is to help you achieve a healthy, singleton birth.
