Purpose : This study was conducted to investigate the dose dependent effects of Panax Ginseng on the reproductive functions in mice. Methods : We used the 8-week-old mice, and administered 0.2ml extract solution of Panax Ginseng in the different concentration once a day for 60 days. The control group was administered 0.2ml normal saline in the same way and duration. We counted the total, motile and normal sperm number of the cauda epididymis and measured the activities of sperm hyaluronidase, peroxidase and catalase of the isolated testis tissues. And we observed histological changes of surgically isolated testis by histochemical methods. Results : All Panax Ginseng extract solution groups showed significantly dose dependent differences in the total number, the motility and normality of sperms compared with the control group, respectively. In the histological analysis of the testicular tissues, all Panax Ginseng extract solution groups showed the enlargement of testicular lobe diameter and apparent angiogenesis between seminiferous tubules. And the activity of typical sperm enzyme, hyaluronidase, was significantly increased in the Panax Ginseng extract solution groups compared to the control group. In the antioxidant activity analysis, the activities of peroxidase and catalase were significantly increased in the Panax Ginseng extract solution groups compared to the control group. Conclusion : This study shows that Panax Giseng has the beneficial effects on the concentration, morphology and motility of sperm, the activities of sperm hyaluronidase, testicular peroxidase and catalase. We can suggest that Panax Ginseng be useful for the treatment of male infertility.

Objective: The strong antioxidant activity of Commiphora mukul prompted us to conduct the present study to explore whether treatment with C. mukul extract (CME) would have any protective influence on sperm parameters, testosterone levels, and plasma glucose levels in streptozotocin (STZ)-induced diabetic rats. Methods: Male Wistar rats were randomly divided into four groups: control, control animals treated with CME, diabetic animals, and diabetic animals treated with CME. CME extract (300 mg/kg) was administered for 60 days by daily gavage. Diabetes was induced by an intraperitoneal injection of 50 mg/kg STZ. The epididymal sperm count, weight, motility, morphology, viability, and serum testosterone and glucose levels were determined. Results: In the diabetic animals, CME decreased blood glucose levels (p< 0.05), increased the total sperm count (p< 0.05), and decreased the proportion of sperm with abnormal morphology (p< 0.05). Diabetes reduced sperm motility (p< 0.001), and CME supplementation partially reversed this effect of diabetes (p= 0.003). Furthermore, in diabetic animals, CME decreased the proportion of immotile sperm (p< 0.001). In rats, diabetes caused a significant decrease (p< 0.05) in serum testosterone levels (F[3, 28] = 3.283, p= 0.035), but treatment of diabetic animals with CME increased serum testosterone levels. Conclusion: The present study demonstrated that C. mukul possesses proandrogenic activity and exerts a beneficial effect on sperm parameters in diabetic rats.

Dioscorea bulbifera tubers contain several phytochemicals of pharmaceutical value. They have been traditionally used for treating various ailments, including postmenopausal symptoms. In the present study, we analyzed the direct effects of Dioscorea tuber extract on mouse spermatozoa. Its contraceptive effect was also evaluated by an intravaginal application before copulation. Mouse spermatozoa were cultured in vitro with various concentrations of the extract. After culturing, the spermatozoa were stained with fluorescein isothiocyanate peanut agglutinin or Coomassie blue to study the acrosome reaction, stained with trypan blue to study the viability, or treated with a hypo-osmotic medium to study the membrane damage. Estrous female mice were intravaginally injected with the extract and copulated with males. The extract induced acrosome exocytosis, viability loss, and membrane damage in a concentration-dependent manner. Female mice treated with the extract showed complete loss of fertility. These observations indicate that the Dioscorea bulbifera tuber extract could be used as a topical contraceptive. Infertility could be due to the precocious acrosome exocytosis of the spermatozoa or membrane damage.
