Host: Darryl S. Chutka, M.D. [@chutkaMD] Guest: Candace F. Granberg, M.D. Developments in cancer treatment have resulted in significant improvements in the survival of malignancy in young children. Unfortunately, these treatments often result in infertility. If these children are pre-pubertal, preservation of mature sperm is not possible. But there is now a procedure which may result in the preservation of fertility by removing testicular tissue, subjecting it to cryopreservation to preserve stem cells capable of producing viable sperm in the future. This procedure is known as testicular tissue cryopreservation and I’ll be discussing it with our guest, Candace F. Granberg, M.D., a urologist at the Mayo Clinic.
