Overview

Egg freezing, also known as mature oocyte cryopreservation, is a method used to preserve reproductive potential in women.

Eggs are harvested from your ovaries, frozen unfertilized and stored for later use. A frozen egg can be thawed, combined with sperm in a lab and implanted in your uterus (in vitro fertilization).

Your doctor can help you understand how egg freezing works, the potential risks and whether this method of fertility preservation is right for you based on your personal and reproductive history.
