Cryopreservation is a medical technique that preserves cells and tissues at extremely low temperatures, enabling future use. It is widely used for fertility preservation, including: Egg freezing – For women undergoing chemotherapy or delaying pregnancy for personal reasons. Sperm freezing – For men prior to medical treatments that may impact fertility. Embryo freezing – A critical component of IVF, allowing couples to store fertilized embryos for future attempts without repeating egg retrieval. How It Works: The process involves freezing in liquid nitrogen at -196°C (-320°F). Two main techniques exist: Slow freezing (older method). Vitrification (modern technique), which rapidly freezes cells, preventing the formation of ice crystals that could damage them. Cryopreservation provides a fertility safety net, enabling individuals and couples to preserve reproductive potential for future use.
