Egg freezing (oocyte cryopreservation) allows women to preserve their eggs at a younger, more fertile age for future use. It is chosen for personal or medical reasons, including delaying parenthood, career or lifestyle planning, or preserving fertility before treatments such as chemotherapy that may affect ovarian function.
Recommended for women wishing to preserve fertility before age-related decline, before undergoing gonadotoxic medical treatment, or for personal family-planning reasons.
