Abstract: It has been reported that melatonin produces either progonadal or antigonadal effects in mammals, depending on the time and mode of administration. Information on the melatonin-effect on the testis in toads indicated varied changes during the breeding and hibernating seasons. The present study in Rana hexadactyla (Lesson), a continuous breeder revealed that administration of melatonin at a dosage of 50 micrograms/frog/day either in the morning or evening for a week inhibited spermatogenesis; however, when melatonin was administered for a longer period, this inhibitory effect was lost. Moreover, treatment with melatonin both in the morning and evening had no net effect on the testes.
