What is Egg Freezing (Oocyte Cryopreservation)?

Egg freezing, or oocyte cryopreservation, is a procedure that extracts, freezes, and stores a woman's eggs for future use. Using vitrification—an ultra-rapid freezing method—eggs are preserved with high survival rates, typically yielding 10-15 mature oocytes per cycle. This option is used for medical reasons (e.g., before chemotherapy) or social reasons (e.g., delaying childbearing).
