Figure 3

Expression of Bcl-2 and Bax proteins in spermatogenic cells in mice (Bar = 100 μm). (a1)–(e1) Expression of Bax protein. (a2)–(e2) Expression of Bcl-2 protein. (a) Control; (b) BPA group; (c) 50 mg·kg⁻¹ LBP group; (d) 100 mg·kg⁻¹ LBP group; (e) 200 mg·kg⁻¹ LBP group. The thick black arrow indicates spermatogenous cell; the thin black arrow indicates the primary spermatocyte; the white arrow indicates Leydig cell.
