Figure 8

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.
