How effective is freezing embryos for future pregnancies?

Dr. Elizabeth A. Newell, MD

Effectiveness of freezing embryos for future pregnancies ranges from approximately 25 percent to 40 percent success rate for implanting when the embryo is placed back after thawing. It can range depending on the health of the embryo and age of the egg when doing an egg retrieval.

If pregnancy is years away, the perfect solution would seem to be to simply store your eggs until you are ready to use them. Every day, I have patients that inquire about freezing eggs to increase the possibility of conceiving if life circumstances put pregnancy on hold.

While freezing embryos (an egg that has been fertilized with sperm and is at an early stage of development) is very successful, the technique of cryopreservation of unfertilized eggs is improving every day but is still considered to be experimental. But if someone doesn’t have sperm in their life, there’s not a lot of choice.

While an increasing number of pregnancies are resulting from frozen eggs, success is not guaranteed since a thawed egg is not always a viable egg. In addition, most women are also not thinking about freezing their eggs when they are in their twenties. By the time someone is considering it (usually in their late thirties), egg quality is already suboptimal. Still, if you have the money and don’t mind going through hormonal stimulation and egg retrieval, egg freezing is currently the best option to stop the clock.
