Oocyte cryopreservation, also known as egg freezing, is a procedure that involves freezing a woman’s unfertilized eggs for future use. This allows a woman to preserve her fertility and have the option to use her own eggs to achieve pregnancy at a later time.

The process of oocyte cryopreservation typically starts with a woman undergoing controlled ovarian stimulation (COS) to stimulate the production of multiple eggs. The eggs are then retrieved using a procedure called transvaginal oocyte retrieval (TVOR), which is similar to a minor surgical procedure, performed under sedation or general anesthesia.

Once the eggs are retrieved, they are immediately frozen using a process called vitrification. Vitrification is a rapid freezing process that helps to prevent ice crystal formation, which can damage the eggs. The eggs are stored in liquid nitrogen at a temperature of -196 degrees Celsius.

Oocyte cryopreservation can be beneficial for women who want to preserve their fertility for various reasons, such as career or personal plans, medical conditions that may affect fertility, or undergoing treatments that may damage the ovaries.

The success rate of pregnancy with cryopreserved eggs varies depending on factors such as the woman’s age at the time of freezing, the number of eggs frozen, and the quality of the eggs.
