BACKGROUND: For patients with well-differentiated thyroid carcinoma (WDTC), the gonadal effects of radioactive iodine (RAI) therapy is an important consideration. OBJECTIVE AND METHODS: We systematically reviewed the controlled studies examining the gonadal effects of RAI therapy in male WDTC survivors. We searched in nine electronic databases. All abstracts and papers were independently reviewed by two reviewers. RESULTS: After reviewing 334 abstracts and 59 full-text papers, seven papers were included. In longitudinal studies examining the effect of single primary RAI dose activities of 594 mCi. Cumulative RAI dose correlated with FSH measurements at long-term follow-up. In one study, approximately one in eight men experienced oligospermia 1 year after RAI therapy. Rates of infertility, pregnancy loss and offspring congenital malformation were not elevated, but studies were limited by small size and self-reported outcomes. CONCLUSIONS: Abnormalities in testicular function are common within several months of a single therapeutic dose of RAI for WDTC. Biochemical abnormalities usually resolve within 18 months after administration of a single activity of < 150 mCi of RAI. The risk of persistent gonadal dysfunction is increased after repeated or high cumulative RAI activities. Controlled, prospective studies, with long-term follow-up, examining male gonadal and offspring effects of RAI therapy are needed.
