Figure 1: Changes in testicular histopathology in different groups (hematoxylin-eosin staining, magnification × 10). A: In the control group, seminiferous tubules are intact. B: In the busulfan group, seminiferous tubules are depleted of spermatogonia (S), primary spermatocytes (SP), Sertoli cells, spermatids and Leydig cells (L). C, D, and E: Honey compound syrup (1.0, 1.5 or 2.0 mg/kg) improves the structure of seminiferous tubules. RI: rupture of interstitum.
