Conditions
Brief summary
Increasing interest has emerged concerning ovarian tissue cryopreservation and subsequent transplantation as a potential way of preserving fertility in cancer patients as well as for women who just wish to delay childbearing. As the majority of existing protocols use the slow freezing method, this study aims to test vitrification techniques of ovarian cortex.
