Figure 8From: Histopathological and ultra structural effects of nanoparticles on rat testis following 90 days (Chronic study) of repeated oral administration TEM of Elongating spermatids. (a) Electron micrograph showing elongating spermatids of control group 1 showing intact acrosome, cell membrane (Me) and condensed nucleus (N). Scale bar =0.5 µm, (b) Elongating spermatids from nanoparticle treated group 2 showing perturbed membrane (Me) and acrosome. Scale bar =0.2 µm, (c) Detachment of the inner acrosomal membrane (Me) from the nuclear envelope. Scale bar =1 µm and (d) Apoptotic spermatid showing collapsed and vacuolated membrane around the nuclear periphery. Scale bar =1 µm.Back to article page
