A rat model of diabetic ED was successfully constructed. (A) Assessment of the fasting blood glucose level in rats (n = 6/group). (B) Assessment of erection number and latency in rats (n = 6/group). (C) Assessment of the serum testosterone level using ELISA (n = 6/group). (D) Histopathological examination of the corpus cavernosum tissues of rats using HE staining (n = 6/group; scale bar = 50 μm). (E) Histopathological examination of the corpus cavernosum tissues of rats using Masson staining (n = 6/group; scale bar = 50 μm). Data were expressed as mean ± standard deviation. **p < 0.01. ED erectile dysfunction, HE hematoxylin–eosin, ELISA enzyme-linked immunosorbent assay.
