Doxorubicin, a chemotherapeutic drug, is known to disrupt the normal spermatogenesis by excess oxidative stress. The present study describes the curative effects of dietary supplemented selenium on doxorubicin‐induced testicular damage in mice. Four groups were included in the study: Group I(C), Group II (Se‐0.5 ppm/kg diet), Group III (Dox‐3mg/kg body weight i.p.) and Group IV (Se + Dox). We analysed microscopic sperm parameters, histopathology, testicular germ cell kinetics, oxidative stress levels, antioxidant levels and mRNA expression studies of apoptotic and stress response markers. Sperm parameters were significantly reduced in doxorubicin‐treated group. Moreover, mice treated with doxorubicin showed an elevation in oxidative stress markers as well as decreased redox ratio, and antioxidant levels were observed in Group III (Dox). However, selenium supplementation ameliorated the damage incurred by doxorubicin, by improving sperm parameters, antioxidant levels and histoarchitecture of mice testes, and decreased the oxidative stress levels. Selenium administration also reduced the levels of apoptotic caspases and stress‐activated kinases in Group IV (Se + Dox) when compared to Group III (Dox). In conclusion, selenium exhibits the curative effect against doxorubicin‐induced testicular damage in mice by attenuating stress conditions and associated apoptosis.
