Children and women of reproductive age may experience loss of fertility for various reasons, including surgeries involving the reproductive organs, chemotherapy, radiotherapy, or idiopathic causes. Since 2006, fertility preservation studies conducted under an international consortium have been developed in both research and clinical centers. Depending on the patient’s age, tumor behavior, and individual factors, gamete or gonadal tissue cryopreservation can be performed.

Clinical outcomes obtained either through the use of preserved gametes or transplantation of thawed tissue are becoming increasingly encouraging. In our country, because gonadal cell and tissue transplantation and gestational surrogacy are not legally permitted, preserving fertility through available methods has gained even greater importance. Since 2014, oocyte (female gamete) cryopreservation has been legally allowed, and although ovarian tissue cryopreservation was initially considered experimental, in recent years it has ceased to be classified as experimental and has become an applicable clinical option.
