Egg freezing is a medical procedure that allows women to preserve their eggs for future use. This process involves stimulating the ovaries with hormones to produce multiple eggs, which are then retrieved through a minor surgical procedure. The retrieved eggs are frozen and stored in liquid nitrogen. Women may choose to freeze their eggs for various reasons, such as delaying pregnancy for personal or professional reasons, or to increase their chances of conception later in life. The frozen eggs can be thawed and fertilized with sperm when the woman is ready to conceive.
