Panax ginseng is known to potentiate the immune system via its antioxidant properties. Cadmium as an environmental pollutant has destructive effects on body organs especially the reproductive system. This study investigated the effects of P. ginseng extract against cadmium-induced testicular toxicity in rats. In this experimental study, 50 male adult rats were randomly divided into 5 groups: A significant decrease was observed in sperm count and viability in the cadmium group versus the control group. Ginseng extract could repair these defects. Increases in apoptotic germ cells due to cadmium were significantly reduced by ginseng extract. Our results demonstrated that P. ginseng extract reduces cadmium-induced testicular toxicity, via anti-oxidative and anti-apoptotic processes.
