a Transmission electron micrograph of sections testis of rats of a control group. showing: spermatogonia (g) with its small nucleus (N), primary spermatocyte cell (ps) with its large nucleus (N); Sertoli cell (r) with its dentate nucleus (n), rest on regular basement membrane (BM) with flat myoid cell (M) nucleus (N) (X 5000). b Transmission electron micrograph of sections testis of rats of a control group. showing: a group of spermatids (t) with a rounded nucleus (N) and acrosomal cap (arrow) and sperm (s) X15000. c Transmission electron micrograph of sections testis of rats of second groups. showing: spermatogonia (g) with its small nucleus (N), primary spermatocyte cell (ps) with its large nucleus (N), Sertoli cell (r) with its dentate nucleus (n), rest on regular basement membrane (BM) with flat myoid cell (M) nucleus (N), spermatids (t) with rounded nucleus (N) and acrosomal cap (arrow) and sperm (s) (X 5000). d Transmission electron micrographs of the third group rat testis showed irregular thick basement membrane (BM) with nuclear atrophy (n) of a myoid cell (M), vacuoles of cytoplasm (v) of degenerated spermatogonia (g) with its degenerated small nucleus (N), also damaged primary spermatocytes (ps), also vacuoles of cytoplasm (V), degenerated mitochondria (m), and endoplasmic reticulum. Also, damage of nuclear membrane (N), atrophy of Sertoli cell (r) with its atrophy nucleus (n) (X 5000)
