Electron micrograph images (TEM) of basement membrane and spermatogonia of rat. (a) Group 1(control) showing normal basement membrane (BM), and spermatogonia (SG). Scale bar =1 µm, (b) Group 2 showing signs of inflammatory damage of testicular tissue in the form of irregular and thickened basal lamina and apoptotic spermatogonial cells. Scale bar =2 µm, (c) Group 2 showing accumulation of nanoparticles near basement membrane (*). Scale bar =2 ?m and (d) Group 2 showing degenerated cytoplasm of seminiferous epithelium. Scale bar =2 µm.
