ED, erectile dysfunction; BMI, body mass index; FBG, fasting blood glucose; TC, total cholesterol; TG, triglyceride; Total T, total testosterone; FA, folic acid; IIEF-5, International Index of Erectile Function-5; PDU, penile Doppler ultrasonography; PSV, peak systolic velocity; EDV, end-diastolic velocity; RI, resistive index.
a statistically significant difference as indicated by one-way ANOVA; b statistically significant difference as indicated by Kruskal–Wallis H test.
The bold values means that there were significant difference between the three group on the compared characteristics.
