Testis of B. papyrifera smoke exposed rat. (A) Seminiferous tubules of the rat exposed to B. papyrifera exhibiting extensive damage on tubules and reduction in size. Disruption of seminiferous epithelium was evident. Spermatogenesis stopped at the primary spermatocytes stage. Interstitial spaces increased and atrophy of Leydig cells (LC); which are sparsely distributed. The germ cells showed overall decrease in cytoplasmic ground substance followed by vacuolization (arrow) at the basal lamina (BL) and towards the lumen (LU) × 1,000. (B) There was a complete disturbance in the spermatogonia (Sg) and spermatids (Sp). Disturbed elongated spermatids were seen at one corner (ES). Lysosome (arrow) like bodies was evident in the section. Vacuolization throughout the cytoplasm, cell debris and disturbed cell organelles were evident. A large micro vesicle (MV) was seen at the basal lamina 8,000×.
