Introduction:
The prevalence of erectile dysfunction (ED) and associated risk factors has been described in many countries, but there are still only a few studies from Asia.
Aim:
We investigated the prevalences of ED and premature ejaculation (PE) in Korean men and the impact of general health, lifestyle, and psychosocial factors on these conditions.
Methods:
To assess ED and PE, 1,570 Korean men aged 40-79 years were interviewed with a self-administered questionnaire on sexual function and the International Index of Erectile Function (IIEF)-5. In addition, blood chemistry was analyzed for each subject.
Main Outcome Measures:
The prevalences of ED and PE were obtained from self-reported ED, IIEF-5 scoring, EF (erectile function) domain scoring, and self-reported intravaginal ejaculatory latency time (IELT). The data were analyzed for the presence of risk factors and the relationship of general health, lifestyle, and psychosocial factors with ED.
Results:
The prevalences of ED among Korean men were 13.4% (self-reported ED) and 32.4% (IIEF-5 score
Conclusions:
The prevalences of ED and PE in Korean men were 13.4% (self-reported ED) and 11% (IELT
