Embryo Freezing

Freezing embryos is a technique that can also help preserve future fertility. Some who choose this procedure are undergoing hormone therapy, cancer treatment, gender affirmation surgery or another medical intervention that affects their fertility.

Embryo freezing, also called embryo cryopreservation, is a process to freeze and store embryos for later use. An embryo is an egg that has been fertilized by a sperm. This process is a way to help people with fertility and reproduction.

What’s the difference between egg freezing and embryo freezing?

Embryo cryopreservation freezes a fertilized egg. Fertility programs also may offer egg freezing, which freezes unfertilized eggs.

Is embryo freezing worth it?

The decision to freeze embryos is personal. Costs vary widely, and medical insurance may not cover fertility treatments. You’ll have to consider your goals, the costs, ethical issues, your partner’s preferences and other considerations.

Does freezing damage embryos?

Freezing can damage embryos. Thawing them later can also damage them. If multiple embryos are frozen, some or all may not survive the process.

Your healthcare provider will talk to you about whether your embryos are suitable for freezing, thawing and implantation.

Is IVF more successful with frozen embryos?
