Testis of B. carterii smoke exposed rat. (A) Seminiferous tubules exposed to B. carterii showed severe effects on the tubules and overall reduction in their size. Degeneration of basal lamina was evident without basal cells. Spermatogenesis stopped completely at the primary spermatocyte stages as seen in the lumen (LU). Interstitial spaces increased and atrophy of Leydig cells were formed (LC). Germ cell such as Spermatogonia (Sg) and Spermatocytes (Sp) were completely disturbed. Cells showed overall decrease in cytoplasmic ground substance followed by vacuolization (arrows) × 1,000. (B) Vacuolization (arrow) in the spermatogonia was evident, which rested on the basal lamina (BL). The basal lamina appeared normal. Cytoplasm (Cy) hypertrophied with other organelles × 8,000.
