title: [Investigation and analysis of chronic prostatitis and sexual dysfunction].
abstract: OBJECTIVE
  To investigate the prevalence of sexual dysfunction in chronic prostatitis patients and its relation with patients' age and the course of disease.
  
  
  METHODS
  Questionnaire surveys were completed by 2 000 subjects who met the criteria for chronic prostatitis after clinical examination and expressed prostatic secretion analysis. Included in the questionnaire were: (1) age, height, weight, occupation, course of disease and treatment received; (2) NIH-CPSI; and (3) IIEF-5.
  
  
  RESULTS
  The prevalence of sexual dysfunction in patients with chronic prostatitis was 49.0% : 26.2% of the subjects with premature ejaculation, 15.0% with erectile dysfunction and 7.7% with both premature ejaculation and erectile dysfunction.
  
  
  CONCLUSIONS
  The prevalence of sexual dysfunction in patients with chronic prostatitis is high, which is negatively correlated with both the age of the patients (P < 0.001) and the course of the disease (P < 0.001).
