Ovarian Tissue Vitrification for Fertility Preservation

In a notable 2012 case, a Japanese woman treated for leukemia delivered a healthy baby after implantation of an egg collected before bone marrow transplant. It has since become possible for women facing cancer treatment to avoid iatrogenic infertility and anticipate pregnancy through ovarian tissue preservation and back-transplantation. It is essential to obtain and preserve the patient’s tissue safely and efficiently through advanced surgical techniques and cryopreservation methods. For widespread benefit, cooperation between institutions and between departments is necessary. Herein, vitrification of ovarian tissue for cryopreservation is described in detail, and recent clinical achievements along with future directions are introduced.
