The aim of this study was to compare the different clinical features of erectile dysfunction (ED) in young and elderly males. From June 2011 to December 2011, 224 pa- tients were included and divided into two groups. Elderly ED group consisted of 120 patients with ED and all were 61 - 90 years old, and young ED group consisted of 104 patients with ED and all were 21 - 45 years old. Questionnaires, physical examination, blood sample test, ultrasound mon- itor, time of achieving erection (TAE), intra-vaginal ejaculation latency time (IELT), ECG and pe- nis-brachial blood pressure index (PBI) were investigated. There were significant differences be- tween the two groups, regarding the top three complications, the body mass index (BMI), Interna- tional Index of Erectile Function-5 (IIEF-5) scores, Self-rating Depression Scale (SDS) total scores, TAE, IELT and PBI. We concluded that clinical features of ED were age-specific, which will be help- ful for treatment strategies and evaluation of the treatment efficacy.
