Baseline characteristics of patients with diabetic erectile dysfunction in three groups.
| Parameters | Group A (n = 34) | Group B (n = 33) | Group C (n = 33) | F Value | P Value |
|---|---|---|---|---|---|
| Age (mean ± SD, yr) | 47.97 ± 5.69 | 46.70 ± 4.93 | 48.30 ± 3.49 | 1.032 | 0.360 |
| ED Duration (mean ± SD, m) | 45.53 ± 21.95 | 43.88 ± 27.16 | 45.27 ± 25.06 | 0.043 | 0.958 |
| BMI (mean ± SD, points) | 23.11 ± 5.99 | 23.33 ± 4.84 | 23.99 ± 3.36 | 0.296 | 0.744 |
| Baseline PSV (mean ± SD, cm/s) | 16.03 ± 2.05 | 15.86 ± 2.03 | 15.94 ± 2.36 | 0.050 | 0.497 |
| Testosterone (mean ± SD, nmol/l) | 15.29 ± 2.74 | 15.35 ± 2.46 | 14.85 ± 2.19 | 0.398 | 0.436 |
| IIEF-EF (score) | 13.38 ± 1.71 | 13.48 ± 1.62 | 13.30 ± 1.61 | 0.101 | 0.904 |
| EHS (score) | 1.82 ± 0.39 | 1.85 ± 0.36 | 1.82 ± 0.39 | 0.060 | 0.942 |
The data was analyzed by one-way analysis of variance (ANOVA) with a significance level alpha=0.05. ED, erectile dysfunction; BMI, body mass index; PSV, peak systolic velocity of penile artery; IIEF-EF, international index of erectile function erectile function domain; EHS, erection hardness score.
