Figure 3: Histopathological findings of the testicular tissues (haematoxylin and eosin stain) in (a) the normal control group (, normal conrtol), (b) the androgen-deprived control group (, Androgen-dep. control), (c) the androgen-deprived 200 mg/kg group (, Androgen-dep. 200), and (d) the androgen-deprived 400 mg/kg group (, Androgen-dep. 400). Compared with the normal control group, a narrow germinal cell layer is observed in the androgen-deprived control group. Scale bars shown in each figure represent 100 μm. And the experiments were repeated for three times.
