Ovarian Tissue Freezing For Fertility Preservation In Women Facing A Fertility Threatening Medical Diagnosis/Treatment

The ovarian tissue will be removed at a UK Healthcare facility and evaluated for gross disease by a pathologist, embryologist, andrologist or REI physician. The ovarian cortex will be dissected from the medulla and cut into strips in culture/holding media, washed to remove blood cells, and cryopreserved. Cryopreservation will be performed using modifications of the techniques described by Gosden et al. (1994) or will be vitrified using a modification of the techniques of Kuwayama et al., 2007.
