Testicular and epididymal histopathology in rats treated with sodium arsenite (50 mg/L). (A) Section showing multiple degenerated or atrophied seminiferous tubules () and germinal epithelial hypoplasia (arrowheads). (B–D) Severe atrophy, necrosis, and degeneration in seminiferous tubules. (E) Tubules with complete germ cell aplasia and Leydig cell hypoplasia (large arrows), with evident atrophy (). (F) Caput epididymis section showing marked reduction in sperm content. (G) High magnification of caput indicating severe acute oligospermia (circles). (H) Cauda epididymis with extremely low sperm presence. Hematoxylin and eosin (H&E) staining; original magnifications: (A–F, H) ×20; (G) ×40.Acronyms: St.d – degenerated seminiferous tubules.
