Perturbation of testicular descension into the scrotum result in cryptorchidism. After surgical correction of cryptorchidism (Orchidopexy), recovery of damaged testicular tissue, were observed gradually. The aim of present study, was to histological evaluation on the effect of Ginseng against testis after Orchidopexy in rat. In this study, 40 male Wistar rats (90-120 gr and 28 days old) randomly were divided in to 4 groups of 10 animals each. In first groups, after Orchidopexy, saline normal used orally for 30 days. In second groups, after Orchidopexy, Ginseng (500mg/kg/day) used orally for 30 days. In third groups, as a sham, after incision, testes were replaced from scrotum to abdominal cavity then returned to scrotum and used saline normal orally for 30 days. In fourth groups, as a healthy control, no operated. At the end of the experimental periods, testicular tissue samples were obtained for morphologic and histomorphometerical studies. The results were analyzed with one-way ANOVA and Tukey test and P<0.05 was considered significant. Results indicated that using of Ginseng, accelerated repairing process of testicular injuries after Orchidopexy. So that diameter of seminiferous tubules and thickness of epithelium of tubules were increased and spermatogenic indices including Tubular differentiation index, Repopulation Index and spermatogenesis Index significantly increased (P<0.05).
