OBJECTIVE In this study, the impact of Finasteride was assessed on the expression of four biomarkers of the spermatogenesis process, namely Dazl, Tsga10, Sycp3, and Prm2 using the Real-Time PCR technique. MATERIALS AND METHODS The experimental protocol was carried out on male NMRI mice for 35 days in which three animal groups received three different doses of Finasteride (1, 5, and 20 mg/body weight). RESULTS The results showed that the expression levels of both Dazl and Prm2 genes were significantly decreased only at a dose of 20 mg/body weight, but at doses of 5 and 20 mg/body weight, the expression levels of Sycp3 and Tsga10 genes were significantly reduced. CONCLUSIONS It seems that Finasteride, at a dose of 5 mg/body weight or higher, may have adverse effects on male spermatogenesis and fertility.
