a Photomicrograph of control epididymis showing normal histological structure of the epididymal tubules (PT) with lining columnar epithelium (arrow) and lumen impacted by sperms (L) (H&E × 200). b–e Photomicrographs of epididymis of the first, second, third, and fourth treated groups showing columnar lining epithelium of the epididymal tubules (PT) with reduction in the number of sperms in lumen (L) (H&E × 200). f–h Photomicrographs of epididymis of the fifth, sixth, and seventh treated groups showing columnar lining epithelium of the epididymal tubules (PT) with large reduction in the number of sperms in lumen (L) (H&E × 200)
