Dr. Mary Zelinski of Oregon Health Sciences University spoke about advances in vitrification of ovarian tissue and follicles in primates. She reviewed her lab’s technique for vitrification in a closed system which has been shown to preserve primordial, primary and secondary follicles in Macaques. Since, their technique has been used by other physicians and scientists for vitrification of human ovarian tissue (more on this to come from Dr. Gracia and Dr. Suzuki). She also reviewed how their lab achieved a live primate birth following transplantation of ovarian tissue to a heterotopic subcutaneous site.
