Despite its deleterious effect on healthy cells and highly regenerating cells such as spermatozoa, Doxorubicin (DOX) is still one of the most used anticancer drugs in the last decades. The present work aimed to investigate the ability of the selenium (Se) and the thiocyanoacetamide (T) to reduce DOX toxicity in gonad. Adult male rats were treated with DOX intravenously (i.v.) at 3.7mg/kg/week associated with Se intragastrically (i.g.) at 0.2mg/kg/day or with T at 10mg/kg/day i.g. After 47days of treatment, sperm quality, biochemical parameters, blood cell count and histological changes in liver, testis and epididymis were assessed. The results showed a poor sperm quality, a perturbation of ionic stability and a significant alteration of lipid metabolism and hematological parameters after the sub-chronic administration of DOX. In testis, DOX exerted serious epithelium damage and numerous seminiferous tubules did not present a normal spermatogenesis. In epididymis, epithelium was altered and mastocytes infiltrated the interstitium. DOX did not exert any significant change in liver except dilatations of sinusoid capillaries. DOX association with Se or T reduced its toxicity on some hematological and biochemical parameters. Both combined treatment improved sperm quality and partially restored spermatogenesis as well as testis and epididymis' normal aspect. These findings brought new sights regarding the effect of Se and a new derivative of T in a combined treatment with DOX on germ cells, gonad and liver. The support of these relevant outcomes with further in vitro studies is necessary to highlight the accurate process involved in Se or T protection against DOX induced damages.
