Abstract

PURPOSE: To obtain basic information for studies of male sexual dysfunction, we investigated the prevalence and the risk factors of erectile dysfunction(ED) in Korean young men via an Internet survey.
MATERIALS AND METHODS
In June 2006, 23594 subjects aged from 20 to 59, who had registered with an internet research company, were asked to join our study if they had had stable sexual activities more than once a month for the past 6 months. Questions covered demographic characteristics, sexual life, International Index of Erectile Function(IIEF), and International Prostatic Symptom Score(IPSS).
RESULTS
A total of 601 subjects completed the questionnaires. The prevalence of self-reported ED was 6.7%. The proportion of men with self-reported ED was 3.7% in the 20-29 age group, 6.0% in the 30-39 age group, and 9.5% in the 40-49 age group. The overall prevalence of ED assessed by IIEF-EF domain score of < or = 25 was 41.0%. We found a statistically significant correlation between men with self-reported ED and lower IIEF-EF domain scores. Self-reported ED was significantly associated with aging, smoking, lower education, and lower urinary tract symptoms (LUTS). Lower IIEF-EF domain scores were correlated with higher IPSS total, voiding and storage scores.
CONCLUSIONS
ED in Korean young men is common and closely associated with LUTS. An Internet survey requires less man power, less time, and less research funds than classical survey methods such as mail or interview surveys. These study results will be useful as basic data for future studies of young Korean men's sexual function
