Fig. 4From: Costus root extract improves testicular toxicity of Bisphenol A in adult male albino rats: histopathological, ultrastructural and biochemical studiesa Transmission electron micrographs of the third group rat testis showed damaged primary spermatocytes (ps) with cytoplasmic vacuolation, degenerated mitochondria, dilation endoplasmic reticulum, vacuoles of cytoplasm (v) of spermatid with irregular acrosomal cap (t), and irregular nuclear membrane (N) close to the lumen (Lu) (X4000). b Transmission electron micrograph of sections testis of rats of the fourth 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) (X5000). c Transmission electron micrograph of sections testis of rats of the fourth group showing: a group of spermatids (t) with rounded nucleus (N) and acrosomal cap (arrow) and sperm (s) X15000Back to article page
