Spermatogenesis study. Results of histological examination. Control group (vehicle: water) (a) Testis (H and E, × 230): Quasi total absence of spermatozoa and germinal cells in seminiferous tubules, (b) Epididymis devoid of spermatozoa, (c) Non active spermatogenesis: approximately 50% of seminiferous tubules are devoid of spermatozoa, Group treated (G. alypum L. 100 mg/kg/24h for 15 days), (d) Testis (H and E, × 560): seminiferous tubules are invaded by spermatozoa and germinal epithelium contains all cell lineages, (e) Epididymis (H and E, × 560): rich in spermatozoa
