Egg freezing is a method used to preserve eggs for future use, particularly for women who wish to delay childbirth or for those undergoing medical treatments that may affect their fertility. Collecting eggs for freezing involves a careful process that includes ovarian stimulation, egg retrieval, and proper storage. The first step is ovarian stimulation, where the woman receives hormone injections to encourage the development of multiple eggs. Once the eggs have matured, they are retrieved through a minor surgical procedure using ultrasound guidance. After retrieval, the eggs are evaluated for quality and then frozen using a technique called vitrification, which involves rapidly cooling the eggs to very low temperatures. This process helps to preserve the eggs' viability for potential future use in in vitro fertilization (IVF) or other assisted reproductive technologies.
