title: [Physical exercise improves erectile function in young and middle-aged men].
abstract: OBJECTIVE
  To assess the association between physical exercise and erectile function in young and middle-aged men.
  
  
  METHODS
  Using Paffenbarger Physical Activity Questionnaire (PPAQ) and IIEF-15, we conducted an investigation among 30- to 45-year-old male outpatients at the clinic of urology. Based on the physical activity described in PPAQ, the patients were divided into a sedentary group (≤ 1,400 Kcal/wk) and an exercise group (> 1,400 Kcal/wk).
  
  
  RESULTS
  The total score on IIEF-15 was signifi- cantly higher in the exercise group than in the sedentary group (62.2 vs 54.4), and so were the scores on the domains of erectile func- tion (26.4 vs 23.3), sexual desire (7.8 vs 6.9), orgasmic function (9.0 vs 8.3), intercourse satisfaction (11.5 vs 9.6), and overall satisfaction (7.5 vs 6.3) (all P < 0.05).
  
  
  CONCLUSIONS
  Increased physical activity is associated with better sexual function in young and middle-aged men.
