Ovarian Cortical Tissue Preservation Through Vitrification - An Overview

Abstract

Cryopreservation of ovarian tissues is becoming an important option for fertility preservation because of its availability and the storage of many immature oocytes besides minimizing the delay needed for freezing mature oocytes or embryos. Ovarian tissue cryopreservation followed by auto-transplantation is a promising method for fertility preservation undergoing gonadotoxic treatment and could also be useful for patients suffering from progressive ovarian dysfunction. Ovarian tissue cryopreservation also has the advantage of storing many immature oocytes inside early follicles. Therefore, Cryopreservation of ovarian tissue has a great potential for preserving genetic diversity, conserving individuals, breeds, or species and adding fundamental knowledge on reproductive biology. The present review presents various aspects of ovarian cortical tissue preservation through vitrification.
