Golden hamsters are seasonal breeders whose reproductive activities are active during summer. Their sexual function is completely suppressed in winter. In oriental society, traditional medicines have been utilized in treating various complaints. One of them is Cynomorium songaricum (CS) whose extract has been used in treating male impotence and sexual dysfunction. We investigated the effects of aqueous CS extract on the process of spermatogenesis in golden hamsters. The animals were divided into 4 groups: long photoperiod (LP) control, short photoperiod (SP) control, and SP animals treated with low or high concentrations of CS. The animals were daily intubated with low (1.25 g/kg) or high (2.50 g/kg) concentrations of the CS aqueous extracts for 8 weeks. The control animals received the vehicle. The volume of testis was measured consecutively from the same animal at 4 week intervals. As results, the LP control animals showed large testes that indicate reproductively active function, but SP control animals displayed remarkably reduced testes that reflect inactive function. The outcomes of the reproductive activity from low concentrations of CS were not conspicuous. And the integral consequences of the reproductive activity from high concentrations of CS treatments were not significant either. But in tracing the individual animals treated with high CS extract, the effects were evidently splitted into dichotomy. In one subgroup small testes were displayed as in SP control animals, but in the other subgroup large testes were demonstrated as in LP control animals, which implies the absolute prevention of regressing activity by SP. These results suggest that the CS extract has a potency to prevent the regressing effects of SP and promotes the male fertility by strengthening the spermatogenesis in the golden hamsters.
