Oocyte cryopreservation is one of the fastest growing areas of reproductive medicine. We have reached a stage where the outcomes are overwhelmingly positive and patients are increasingly coming back to utilize those oocytes for family building. However, there is significant debate as to when is the optimal age to cryopreserve oocytes to maximize reproductive outcomes down the road. We debate this issue live from the Society for Reproductive Endocrinology and Infertility Fellows Retreat in Park City, Utah.
