title: Prevalence of sexual dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome: a meta-analysis.
abstract: OBJECTIVE
  This study aims to estimate the prevalence of sexual dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) by conducting a meta-analysis.
  
  
  METHODS
  Relevant publications were searched using PubMed, Embase, CBM, China National Knowledge Infrastructure, VIP and Wanfang databases up to August 2015. Studies that reported the prevalence of erectile dysfunction, premature ejaculation and total sexual dysfunction in men with CP/CPPS were included.
  
  
  RESULTS
  A total of 24 studies involving 11,189 men were included. Overall prevalence of sexual dysfunction in men with CP/CPPS was 0.62 (95 % CI 0.48-0.75), while the prevalence of erectile dysfunction and premature ejaculation was 0.29 (95 % CI 0.24-0.33) and 0.40 (95 % CI 0.30-0.50), respectively. From 1999 to 2010, the prevalence of sexual dysfunction, erectile dysfunction and premature ejaculation was 0.65 (95 % CI 0.45-0.83), 0.27 (95 % CI 0.22-0.33) and 0.41 (95 % CI 0.27-0.55), respectively. From 2011 to 2014, the prevalence of sexual dysfunction, erectile dysfunction and premature ejaculation was 0.50 (95 % CI 0.22-0.75), 0.35 (95 % CI 0.29- 0.40) and 0.39 (95 % CI 0.37-0.41), respectively.
  
  
  CONCLUSIONS
  The prevalence of sexual dysfunction in men with CP/CPPS was high, even though overall sexual dysfunction demonstrated a slightly decreasing trend. Furthermore, erectile dysfunction prevalence rate had an increasing trend in recent years. More prospective studies are needed to evaluate sexual dysfunction improvement with better management of CP/CPPS.
