About

• Egg freezing is a process in which a woman’s eggs (oocytes) are extracted, frozen and stored as a method to preserve reproductive potential in women of reproductive age. 
• It is also called egg banking, egg cryopreservation, and oocyte cryopreservation.

Who Needs Egg (oocyte) Freezing?

• Women with cancer requiring chemotherapy and/or pelvic radiation therapy that may affect fertility.
• Women who undergo surgery that may cause damage to the ovaries.
• Risk of premature ovarian failure because of chromosomal abnormalities or family history of early menopause.
• Women with any ovarian disease with risk of damage to the ovaries.
• Fertility preservation for social or personal reasons to delay childbearing.

How Will Eggs be Used in the Future?

• When the woman is ready to use the frozen eggs to achieve pregnancy, these cryopreserved eggs are placed in a warming solution and assessed. 
• Those eggs that survived the freezing process are fertilized by injecting a  sperm directly into the egg, and the fertilized eggs will grow in culture until the embryo(s) are ready to be transferred into the uterus to achieve pregnancy, typically 3-5 days after fertilization.
