Testicular tissue cryopreservation

Given the better survival rates for many cancers, even cancers occurring in childhood, quality of life has become an important issue in cancer treatment [8]. While sperm banking is the golden standard to preserve male fertility in adult men undergoing potential sterilizing treatment [9], not all adult men present spermatozoa in their ejaculates when cancer is being diagnosed [10]. When cancer is diagnosed in childhood, active spermatogenesis is not present, ; hence cryobanking of spermatozoa is not an option. When ejaculated spermatozoa cannot be cryopreserved, cryopreservation of testicular tissue either containing spermatozoa or spermatogonial stem cells may be considered.
