Effect of cashew (Anacardium occidentale L.) nut-supplemented diet on steroidogenic enzymes, hormonal and oxidative imbalances, and sperm parameters in cisplatin-induced reproductive toxicity in male rats.

Cisplatin (CP) is a chemotherapeutic/anticancer drug culpable in sperm and testicular damage, but the use of dietary patterns has been reported to averse this effect. To date, no report on the use of roasted cashew nut-supplemented diets (RCNSD) against chemotherapy-induced testicular damage has been presented. In this study, the effect of 10% and 20% RCNSD on reproductive hormones, sperm parameters, testicular and epididymal antioxidant status, and steroidogenic enzymes activities in CP-induced rats were determined. Interestingly, these parameters were boosted, but with a decrement in radical species level in the testes/epididymis of CP-induced rats fed with RCNSD as against the untreated CP-induced rats. The modulatory effect of RCNSD on the tested reproductive parameters in studied tissues could be among the mechanism of action, by which RCNSD mitigates andrological toxicity. Hence, RCNSD could be harnessed as a functional food/nutraceutical agent for alleviating the andrological toxicity of CP-induced male reproduction. PRACTICAL APPLICATIONS: Consumption of cashew nuts has been a great benefit to human health, as a result of its richness in nutritional constituents including biologically active amino acids, tocopherols, fatty acids, polyphenols, and selenium, among others. Cashew nuts are mostly consumed fried/roasted, with yoghurt, as a paste, or used as an ingredient in confectionery products. The folkloric use of cashew nuts in the management of cardiovascular diseases, male reproductive disorders, and diabetes has been reported. In this study, the ability of roasted cashew nut-supplemented diets to modulate reproductive hormones, sperm parameters, testicular and epididymal antioxidant status, and steroidogenic enzymes activities in CP-induced reproductive toxicity in male rats was revealed, thus, indicating its possible use, clinically, in the management of reproductive toxicity induced by cancer drugs.
