The means and standard deviation were calculated where appropriate. Statistical differences were determined by the ANOVA followed by Dunnett’s test and the level of significance set at p < 0.05. In many cases results were calculated as percentage of relevant control values (as the control values could vary between cell preparations and between experiments) to make understanding of the results easier. During the period of treatment with HOCS, there were no significant changes in the body weights of treated and untreated

animals; weight gain was normal in all the experimental groups. But there was a significant AUY-922 ic50 decrease in the sex organ weights, namely testis, epididymis and seminal vesicle in all treated groups. Sex organ weights were highly decreased in the group III animals when compared to that of control animals (Table 1). The sperm of the control rats had normal counts, motility, and morphology (Table 2). In HOCS treated rats, the cauda epididymal sperm parameters showed evidence of dose dependent infertility. The sperm counts were significantly decreased in group II, group III and group IV animals compared to that of normal animals (Table 2). In group IV animals, the sperm counts were highly reduced Rucaparib order when compared

to that of control rats. The sperm motility was highly inhibited in group II, group III and group IV animals (Table 2). More than 50% of the sperm had abnormal morphologies of various kinds, which included broken head, DNA damage sperm, coil in tail region of two or more sperm etc., were observed (Fig. 1). The plant extract intoxication exerted a significant decrease epididymal sperm concentration and sperm progress motility. The live/dead sperm count was increased in group II, group III and group IV animals. The reduction of sperm count and sperm motility were significantly (p < 0.05) higher in group IV treated animals when compared to that of control. Light photomicrography of the testicular tissue of vehicle treated rat showing intact lumen of seminiferous tubule, intact because basement membrane

and sertoli cells, intact interstitial tissue, cells of Leydig, and peritubular capillaries and venules. HOCS at 200 mg/kg, showing slight seminiferous tubular degeneration with scattered areas of interstitial edema (Fig. 2). There was also necrosis of the sertoli cell responsible for supporting developing spermatocytes. 300 and 400 mg/kg bw treated animals showing moderate to severe degeneration of the seminiferous tubules and shrinkage. Herbal drugs have been used since ancient times as medicine for the treatment of a wide range of diseases. Over the past decade, interests in drugs derived from higher plants, especially the phototherapeutic ones, have increased expressively. It is estimated that about 25% of all modern medicine are directly or indirectly derived from higher plants.7, 8, 9 and 10 The anti-fertility effect of HOCS confirmed by following measures.
