The prevalence of erectile dysfunction and its relation to chronic prostatitis in chinese men

Abstract

This study was performed to evaluate the prevalence of erectile dysfunction (ED) and to explore its correlation to chronic prostatitis in China.

In total, there were 12 743 respondents, giving a response rate of 84.95%. Among 7372 eligible men, ED prevalence as assessed by self-report and IIEF-5 score was 12.0% and 17.1%, respectively. Among 771 men with prostatitis-like symptoms, ED prevalence as assessed by self-report and IIEF-5 score was 39.3% and 30.1%, respectively. Among 370 men suffering from chronic prostatitis, ED prevalence as assessed by self-report and IIEF-5 score was 40.5% and 35.1%, respectively. The prevalence of self-reported and IIEF-5 score-assessed ED had high correlation with increasing age among all eligible men, men with prostatitis-like symptoms, and men with chronic prostatitis (Pt
