Oocyte cryopreservation

Oocyte cryopreservation is a process in which a woman's oocytes (eggs) are extracted, frozen and stored. Later, they can be thawed, fertilized, and transferred to the uterus as embryos. This process is a part of Assisted reproductive technology (ART).

History[edit | edit source]

The first human birth from a frozen oocyte was reported in 1986. Since then, the technology has advanced and become more widely accepted. The American Society for Reproductive Medicine (ASRM) removed the experimental label from this procedure in 2012.

Procedure[edit | edit source]

The procedure for oocyte cryopreservation includes several steps: ovarian stimulation, egg retrieval, freezing, and storage. The eggs are typically frozen using a process called vitrification, a rapid freezing technique that prevents the formation of ice crystals.

Uses[edit | edit source]

Oocyte cryopreservation is used for several reasons. It can be used by women who want to preserve their fertility for the future, for medical reasons such as cancer treatment, or for use in in vitro fertilization (IVF) procedures.

Risks and Success Rates[edit | edit source]

There are risks associated with oocyte cryopreservation, including the risks of ovarian stimulation and egg retrieval procedures. The success rates of using frozen eggs in IVF procedures vary and depend on factors such as the woman's age at the time of egg freezing and the specific techniques used.
