Figure 4. a: H&E stained sections of the control testis showing the seminiferous tubules (St) are lined by stratified germinal epithelium (G).

Interstitium (I) containing clusters of interstitial cells (arrow head) are also detected.
b: Group II testicular sections show the covering tunica albuginea (C) with congested sub-capsular blood vessels (V). Some St appear with disorganized separated germinal epithelium (arrow) from their basement membranes.
c: Some St in the same group showing marked cellular loss and absence of sperms in most of them. Some germ cells have dark pyknotic nuclei (arrow). Acidophilic vacuolated hyaline material (double arrow) is detected in the interstitium.
d: In the follow up group St are lined by germinal epithelium (G). Few germ cells appear with dark pyknotic nuclei (arrow). Interstitium (I) containing clusters of interstitial cells (arrow head) (H&E×400, Scale bar; 20μm).
