title: [Investigation of sexual function in 623 patients with chronic prostatitis].
abstract: OBJECTIVE
  To investigate the influence of chronic prostatitis on premature ejaculation (PE) and erectile dysfunction (ED) and the correlation of chronic prostatitis with PE and ED.
  
  
  METHODS
  We adopted NIH-CPSI, CISFPE and IIEF-5, interviewed 623 patients with chronic prostatitis, and recorded their scores on the above systems.
  
  
  RESULTS
  The incidence of PE was 39.0% and the rates of the mild, moderate and severe types were 26.2%, 12.0% and 0.8%, respectively. It developed mostly among the younger patients, accounting for 42.9% (103/240), 37.0% (95/257) and 35.7% (45/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. The incidence of ED was 16.9% and the rates of the mild, moderate and severe types were 14.9%, 1.0% and 1.0%, respectively. It occurred mostly among the older patients, accounting for 13.8% (33/240), 11.3% (29/257) and 34.1% (43/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. Analyses revealed no significant correlation among the scores on NIH-CPSI, CISFPE and IIEF-5.
  
  
  CONCLUSIONS
  There is a high incidence of PE and ED among patients with chronic prostatitis, but without significant correlation between the severity of chronic prostatitis and that of PE and ED.
