Abstract: The successful treatment of males with cancer has led to increasing numbers of men and boys interested in life after cancer. One of the top priorities for many of these males is the opportunity to have a family. Most cancer treatments used for common malignancies in men and boys are associated with impaired fertility; for patients receiving alkylating agents or total body irradiation, severe fertility impairment occurs in most patients. While sperm banking for males, even those as young as 12, facing sterilizing cancer treatment can be effective, this approach requires subsequent use of reproductive procedures such as in vitro fertilization (IVF) or intrauterine insemination to achieve a pregnancy. Most males would prefer to restore their natural ability to father children and avoid these expensive and invasive approaches. No proven method for human male fertility restoration has yet been demonstrated; however, work in many mammalian species and recently in primates has demonstrated that autologous testicular cell transplant (TCT) can restore spermatogenesis after cancer treatment. Promising work in non-primate species has demonstrated the feasibility of in vitro development of mature sperm from neonatal testicular tissue. The safety and efficacy of either approach has not been established in humans. The objective of this lecture is to explore current and future fertility preservation and restoration techniques for males at risk of sterility from medical and surgical treatment.
