Melatonin-induced inhibition of testicular function in adult golden hamsters
Abstract:
Melatonin (12-100 mug/day) administered via subcutaneous Silastic implants prevented or suppressed light-induced testicular recrudescence in adult golden hamsters. In addition, melatonin (150 mug/day) induced marked testicular regression in sexually mature hamsters maintained on photostimulatory long days. These results clearly establish that exogenous melatonin can inhibit gonodal function in adult male hamsters.
