Background: Carbon tetrachloride (CCl4) is an industrial solvent that causes kidney, lung, testicles, brain, and blood diseases. In the present study, we investigated protective effects of Sophora pachycarpa extracts on testicular histopathology damage in rats intoxicated with carbon tetrachloride (CCl4). Methods: In this study, divided into six experimental groups (n = 6): 3 groups as pre-treatment, received extract of S. pachycarpa at 50 mg/kg/day, 100 mg/kg/day, and 250 mg/kg/day doses by gavage procedure for 21 days before intraperitoneal injection of 500 µL/kg CCl4 on the day of 21, control group receiving 500 µL/kg CCl4 on the day of 21, post-treatment group received 100 mg/kg/day extract for 10 days and 12 h after injection of 250 µL/kg CCl4. The testicular tissues were samples at the end of the treatments for histological examination. Results: Histopathological examination of testis in CCl4-treatment group showed degeneration in seminiferous tubules and germ cells, intercellular dehiscence, and loss of cells into the lumen. Treatment of S. pachycarpa extract (250 mg/kg) resulted in remarkable improvement in testicular histopathological alterations caused by CCl4 in testis sections. Conclusions: Based on the findings, it is concluded that the extract of Sophora pachycarpa can improve the adverse effects of CCl4 on testicular tissue, possibly via its bioactive compounds having antioxidant effects.
