Teucrium polium attenuates carbon tetrachloride-induced toxicity in the male reproductive system of rats.

The aim of this study was to investigate the protective effects of Teucrium polium (T. polium) on carbon tetrachloride (CCl4 )-induced male reproductive system damage. The effects of T. polium and vitamin C (Vit C) on sperm parameters, gonadotrophin and testosterone levels, oxidative status and testis tissue structure were assessed in CCl4 -treated male rats. CCl4 caused significant alteration of sperm parameters in epididymal and testicular tissues, a decrease in hormone levels, and a decrease in antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) in testicular tissues. A noteworthy increase in malondialdehyde (MDA) level was induced in CCl4 -treated rats with some histopathological damages on the testes compared with control group. Remarkable ameliorations were observed with respect to all the previous parameters, following the administration of CCl4 with T. polium, and with vitamin C used as a positive control, when compared with CCl4 alone. Teucrium polium extracts showed good antioxidant performance, suggesting its protective effect against chemically induced reprotoxicity.
