Objectives : This study aimed to investigate the effects of Shingi-whan(SG) on the male reproductive and sexual function, so we measured the spermatogenesis and the testicular toxicity in mice and the vasorelaxation in isolated rabbit corpus cavernosum smooth muscle.
Methods : To evaluate effect on the spermatogenesis in mice, we prepared two groups, control group and SG group that was orally administered SG(1,000mg/kg) for 20 days, and compared. To analyze testicular toxicity in mice, we also prepared two groups, doxo group that was injected with doxorubicin (3mg/kg) on three times and doxo + SG group that was injected with doxorubicin and SG for 20 days, and compared. To investigate sexual function of SG in mice, we prepared three groups, normal group and aging elicited group consisting of 18-month-old mice, SG treated aging group that was orally administered SG for 60 days, and compared using histochemical staining on mice corpus cavernous tissues. In order to define the relaxation effects of SG, rabbit corpus cavernous tissues were prepared in 2 × 2 × 6 ㎜ sized strip. Then the dose-dependent relaxation responses of SG at 0.01-3.0 ㎎/㎖ in contracted strips induced by phenylephrine were measured.
Results : The sperm density in dutus epididymis and the diameter of seminiferous tubules of SG group was significantly increased when compared to control group. The testicular weight and the diameter and height of epithelial layer of seminiferous tubules of doxo + SG group was significantly increased when compared to doxo group. The cavernous strips were significantly relaxed by SG extract In SG treated aging group, ratio of smooth muscles to collagen fibers and red blood cell count in venous sinus was increased as compared to aging elicited group.
Conclusions : Our findings have shown that SG extract have effect on spermatogenesis and mitigating effect on doxo-induced testicular toxicity. Further, it also have the vasorelaxant effect on rabbit corpus cavernosum.
