Testicular cancer is the most common cancer affecting men of reproductive age. Advances in treatment of the disease, which includes the administration of cisplatin, have brought the 5-year survival rate to over 90%. This high cure rate, coupled with young age of patients, makes elucidation of the impact of the treatment on reproduction become increasingly important. The objective of the present study was to investigate the protective effect of speman, a non-hormonal herbal formulation, on cisplatin-induced suppressed male reproductive health in mice. Male mice were treated with cisplatin or speman alone or in combination and assessed for spermatogenesis and steroidogenesis. Significant decrease in the weights of testes and epididymis was observed in cisplatin treated animals. Injection of cisplatin significantly decreased epididymal sperm count, viable sperms, motile sperms and hypo-osmotic swelling (HOS)-tail coiled sperms with a significant reduction in the testicular steroidogenic enzyme activities and serum testosterone levels, whereas co-administration of speman with cisplatin showed a significant improvement in the selected reproductive parameters over cisplatin alone treated mice indicating the beneficial effect of speman to combat cisplatin-induced suppressed reproduction in male mice.
