Figure 2: Section of mature albino rats’ testis of control group (I and II) showing normal, intact rounded or oval seminiferous tubules. H&E (Obj.4X : Oc.10X). (B): Section of mature albino rats’ testis of control group showing that the seminiferous tubules were laterally separated from each other by a considerable amount of interstitial connective tissue. H&E (Obj.10X: Oc.10X). (C): Section of mature albino rats’ testis of control group showing normal interstitial connective tissue with ovoid or polygonal leydig cells (arrow) and flat myoid cells (arrow head). H&E (Obj.40X: Oc.10X). (D): Section of mature albino rats’ testis of control group showing the normal seminiferous tubules that was lined with stratified seminiferous epithelium; proliferating highly divided numerous spermatogenic cells with non-divided elongated sertoli cells. H&E (Obj.40X: Oc.10X). (E): Section of mature albino rats’ testis of control group showing that the stratified seminiferous epithelium rested on a thin basal lamina and is formed of different types of spermatogenic cells which represented the different stages of spermatogenesis. H&E (Obj.40X: Oc.10X). (F): Section of mature albino rats’ testis of exposed group to EMF (III) showing proliferation and hyperplasia of the interstitial connective tissue and leydig cells (arrow). H&E (Obj.40X: Oc.10X). (G): Section of mature albino rats’ testis of exposed group to EMF (III) showing atrophy in the seminiferous tubules and disorganization of the germinal epithelium with loss of the spermatogenic cells specially spermatocytes and spermatids (arrow). Dilatation of the interstitial blood vessels with marked congestion and engorgement with large number of blood cells (star). H&E (Obj.10X: Oc.10X). (H): Section of mature albino rats’ testis of exposed group to EMF (III) showing degeneration and necrosis of the spermatogenic cells. H&E (Obj.100X: Oc.10X). (I-K): Section of mature albino rats’ testis of group (IV) that kept for 48 days post the end of exposure to EMF without exposure showing the normal, intact seminiferous tubules Figure 2I.
