Royan Institute First Attempts: Autotransplantation of Vitrified Human Ovarian Tissue in Cancer Patients

Abstract

Today, timely diagnosis and therapeutic progress open a road of hope for survival in cancerous patients. Increasedknowledge about the various cytotoxic treatment's impacts on ovarian function and fertility has resulted in a surgein the number of patients seeking to preserve their fertility before starting the anti-cancer treatment process. In thisregard, embryo cryopreservation can be recommended for fertility preservation when the woman is married and hasadequate time for ovarian stimulation. If patients are prepubertal girls or not married women, oocytes or ovarian tissuecan be frozen instead to be used in the future. In this regard, the first attempts for ovarian tissue transplantations wereconducted in 2016 and in 2019 for two cancerous patients whose ovarian tissue was cryopreserved in the RoyanHuman Ovarian Tissue Bank (Tehran, Iran). Unfortunately, the transplantations did not result in a live birth.
