The rats were killed humanly at the end of treatment period and their testes were removed and weighed. For histopathological evaluations, tissue sections stained by Hematoxylin and Eosin (H&E). The result obtained for the 3 groups were compared using nonparametric Kruskal-Wallis test. P The volume of testis in the treatment group 2 in comparison with control and treatment group 1 showed a decrease and necrosis of seminiferous tubules and increasing of interstitial tubules in treatment group 2 in comparison with the other two groups showed a significant increase. Number of seminiferous tubules, leydig-cells, thickness of germinal epithelium, spermiogenesis index, tubules differentiated index in treatment groups 1 and 2 was significantly lower than the control group (pž Using buprenorphine drug can increase infertility to reasons, decrease spermatogenesis and necrosis on seminiferous tubules.
