Frozen eggs refer to human eggs that have been harvested from a woman's ovaries and preserved through a process called cryopreservation. This technique allows women to store their eggs for future use, often for fertility treatments or to delay pregnancy. The eggs are cooled to very low temperatures to maintain their viability. The process of freezing eggs typically involves hormone stimulation to produce multiple eggs, which are then retrieved and frozen. This option is popular among women who wish to focus on their careers or personal goals before starting a family, as well as those undergoing medical treatments that may affect fertility, such as chemotherapy.
