Mahboubeh Vatanparast, Mohammad Ali Khalili, Nahid Yari, Bryan Woodward, Mehdi Mohsenzadeh
PURPOSE: Ovarian tissue (OT) cryopreservation is a treatment option for fertility preservation among young cancer patients. However, the procedure may involve a reduction in the GDF9-β expression and a delay in follicular growth after thawing and transplantation. The aim of this study was to evaluate whether supplementation of GDF9-β can compensate the reduction of this factor during the cryopresevation process and promote folliculogenesis after transplantation of thawed sheep ovarian tissue...
