a A photomicrograph of C.S. of testis from the group (III) showing moderate spermatogenic arrest (*), few spermatogonia (sg), decreased in number of sperms (T) and spermatids in the seminiferous tubule, and interstitial spaces with Ledge cells (L) H&E (× 400). b A photomicrograph of C.S. from the group (IV) rat testis showing disorganized irregular outline seminiferous tubule, disruption of the epithelial lining of the tubules, and impaired arrested spermatogenesis (Sc); detached germ cells, spermatogonia, and deteriorated spermatids (sd); degeneration of spermatogenic elements with appearance of vacuoles (*); and reduction of sperm in the lumen and rarity of Leydig cells.
