Cryopreservation and Transplantation of Ovarian TissueDONNEZ, JACQUES MD, PhD; DOLMANS, MARIE-MADELEINE MD, PhDClinical Obstetrics and Gynecology: December 2010 - Volume 53 - Issue 4 - p 787-796 doi: 10.1097/GRF.0b013e3181f97a55 Fertility Preservation: New Developments Abstract Author Information Cryopreservation and autotransplantation of ovarian tissue for fertility preservation is considered an experimental technique. However, in some clinical situations it remains the only option. Eleven pregnancies have been reported worldwide from this procedure. Transplantation of ovarian tissue pieces without a vascular pedicle requires the establishment of a new blood supply that takes 5 days. This leads to a substantial loss of follicles in the graft that may limit the longevity of the graft.
