Oocyte banking

Oocyte cryopreservation or vitrification (egg freezing) is a rapidly advancing, breakthrough technology in which a woman’s eggs (oocytes) are extracted, frozen and stored (oocyte bank). Later, when she is ready to become pregnant, the eggs can be thawed, fertilized, and transferred to the uterus as embryos.

Unfortunately, over 50,000 reproductive-age women are diagnosed with cancer each year in the United States only. Chemotherapy and radiotherapy are toxic for oocytes, leaving few viable eggs. Egg freezing offers women with cancer the chance to preserve their eggs to have children in the future.

Oocyte cryopreservation is aimed at three particular groups of women: those diagnosed with cancer who have not yet begun chemotherapy or radiotherapy; those undergoing treatment with assisted reproductive technologies who do not consider embryo freezing an option and those who would like to preserve their future ability to have children, either because they do not yet have a partner, or for other personal or medical reasons.

Oocyte cryopreservation is an essential option for individuals undergoing IVF who object, either for religious or ethical reasons, to the practice of freezing embryos. Having the chance to fertilize only as many eggs as will be utilized in the process and then freeze any remaining unfertilized eggs can be a positive solution. In this way, there are no excess embryos created, and there is no need for unused frozen embryos disposition, a practice that can develop complex choices for specific individuals.

Egg freezing can also benefit women who desire to postpone childbearing for education, career, or other reasons. Freezing eggs at an early age may ensure a chance for a future pregnancy.

Additionally, women with a family history of early menopause are interested in fertility preservation. With egg freezing, they will have a frozen store of eggs, likely that their eggs are depleted at an early age.
