Protective effect of Lycium barbarum polysaccharides against cadmium-induced testicular toxicity in male mice

) only. Pretreatment with LBP ameliorated the Cd-induced reduction in the body weights, sperm motility as well as the level of testosterone in serum. Moreover, Cd-induced increase in the abnormal sperms was reduced and effects of Cd on the levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were reversed. Histopathological examination further confirmed that the LBPs effectively attenuated Cd-induced degeneration of seminiferous tubules. Thus, LBPs attenuated Cd-induced testicular injury by improving the activity of antioxidant enzymatic activity and lowering the oxidative stress, so it could be a potential auxiliary therapeutic agent for Cd-induced testicular toxicity.
