OBJECTIVE: To identify the role of 5alpha-reductase in the spermatogenesis of male rats by studying the effect of two 5alpha-reductase inhibitors, Epristeride and Finasteride, on the spermatogenesis in male Sprague-Dawley (SD) rats. METHODS: Changes in the weight of the testis, serum testosterone and dihydrotestosterone levels, epididymal sperm count, and reproductive function were observed and analyzed after the two 5alpha-reductase inhibitors were administered to male SD rats orally. RESULTS: The experiment showed that in comparison with control animals, both the two 5alpha-reductase inhibitors: 1. suppressed the development of the prostate and reduced the weight of the testis in the experimental groups (P < 0.05); 2. decreased the serum level of dihydrotestosterone and enhanced testosterone; 3. inhibited epididymal sperm count and productive function. CONCLUSION: High dosages of the 5alpha-reductase inhibitor, Epristeride, can suppress the development of the prostate and reduce the weight of the testis, decrease dihydrotestosterone, and inhibit spermatogenesis and productive function in male rats.
