title: Epidemiology of premature ejaculation.
abstract: OBJECTIVE
  Accumulating evidence suggests that premature ejaculation is the most common sexual symptom. This review focuses on the epidemiology of premature ejaculation from geographical and medical perspectives.
  
  
  RESULTS
  In the past year many articles have been published using the data from the Global Study of Sexual Attitudes and Behaviors, a large survey that investigated various aspects of sex and relationships among 27 500 men and women aged 40-80 years. Despite some methodological bias, discussed herein, a prevalence of more than 21% seems a realistic figure for premature ejaculation.
  
  
  CONCLUSIONS
  Premature ejaculation is the most prevalent sexual dysfunction in every country.
