Introduction: In addition to the previously known lifelong and acquired premature ejaculation (PE) syndromes, the existence of two more PE syndromes has been suggested: natural variable PE and premature-like ejaculatory dysfunction. However, epidemiological studies investigating the prevalence of these four PE syndromes have yet to be conducted.
Aim: To determine the prevalence of the complaint of ejaculating prematurely across the four PE syndromes.
Methods: This study, conducted between June 2009 and December 2009, was designed as a non-interventional, observational cross-sectional field survey. Participating couples were randomly selected from 17 provinces of Turkey. All participants were asked to complete a questionnaire including data regarding demographics, socioeconomic status, social and cultural factors, medical and sexual history, current medications, and ejaculation time. Subjects with a complaint of ejaculating prematurely were classified as lifelong, acquired, and natural variable PE, or premature-like ejaculatory dysfunction.
Main outcome measures: The main outcome measures were prevalence of complaint of ejaculating prematurely in the general population and across the four PE syndromes.
Results: A total of 2,593 couples (mean age, 41.9±12.7 years for males and 38.2±12.1 years for females) were enrolled. Five-hundred twelve subjects (20.0%) complained of ejaculating prematurely. Fifty-eight (2.3%), 100 (3.9%), 215 (8.5%), and 131 (5.1%) subjects were classified as lifelong, acquired, and natural variable PE, and premature-like ejaculatory dysfunction, respectively.
Conclusions: The prevalence of the complaint of ejaculating prematurely among Turkish men was 20.0%, with the highest PE syndrome being natural variable PE (8.5%) and premature-like ejaculatory dysfunction (5.1%).
