When you choose to use your frozen eggs, they'll be thawed, fertilized with sperm in a lab, and implanted in your or a gestational carrier's uterus.

Your health care team might recommend using a fertilization technique called intracytoplasmic sperm injection (ICSI). In ICSI, a single healthy sperm is injected directly into each mature egg.

About 75 to 80 percent of eggs survive freezing and thawing, and a similar amount will be successfully fertilized. The chances of becoming pregnant after implantation are roughly 40 to 50 percent, depending on your age at the time of egg freezing. The older you are at the time of egg freezing, the lower the likelihood that you'll have a live birth in the future.

Keep in mind that pregnancy rates might be lower when frozen eggs are used, compared with fresh or frozen embryos.
