Ovarian tissue cryopreservation is emerging as a promising alternative for both fertility preservation and reproductive lifespan extension. Unlike oocyte cryopreservation, ovarian tissue cryopreservation restores endocrine function, potentially delaying menopause and reducing associated health risks. Although concerns exist regarding graft longevity and surgical invasiveness, recent advancements-such as improved cryopreservation techniques, neovascularization strategies, and minimally invasive approaches-enhance its feasibility.
