The aim of the current study was to investigate antioxidant, anti-inflammatory and anti-apoptotic effects of Origanum vulgare on finasteride-induced oxidative injury in mouse testis and sperm parameters. Thirty BALB/c mice were divided into 5 groups: negative control, received 0.5 ml/day distilled water; positive control, received 25 mg/kg finasteride orally; and three groups received 100, 200 and 400 mg/kg/day O. vulgare extract plus 25 mg kg dayfinasteride for 35 days. At day 36, serum luteinising hormone, follicle-stimulating hormone and testosterone, inflammatory cytokines (IL-6, TNF-α, IL-1β), glutathione peroxidase, superoxide dismutase and nitric oxide levels were assessed. Also, apoptotic changes investigated through genes expression and immunohistochemical staining. Finasteride in 35 days resulted in significant destructive alterations in the testis architecture, suppressed antioxidant enzymes and increased lipid peroxidation. The expression of Bcl-2 was down-regulated, whereas p53 and caspase-3 were up-regulated. Origanum vulgare improvedthe serum level of hormones and restored the antioxidant defence. 200 and 400 mg/kg/day of O. vulgare alleviated the testis structure and sperm parameters, up-regulated the anti-apoptotic gene Bcl-2 and down-regulated the p53, caspase-3 genes in treated groups. The findings indicate that O. vulgareextract improved function and structure of testis tissue against finasteride-induced testicular toxicity.
