Figure 1. Histoarchitecture of the testes stained with H&E, X100. Group A, B, C and D rats showed normal cellular composition in their germinal epithelium (GE) with sperm cells in the lumen (L) and a normal interstitium. Also showed a normal spermatogenesis, better association and higher density of spermatogenic cells, complete maturation of germinal epithelium (GE) and lumen (L) contains full-mature spermatozoa.
