This study compared the prevalence of premature ejaculation (PE) diagnosed by the PE diagnostic tool (PEDT) score, self-reporting and stopwatch-recorded intravaginal ejaculation latency time (IELT). It examined the characteristics of males diagnosed with PE by each criterion. A questionnaire survey enrolled 2081 subjects from March to October, 2010. Stopwatch-recorded IELT was measured in 1035 of the 2081 subjects. We aimed to determine whether PE has an influence on the frequency and satisfaction of sexual intercourse, the degree of libido/erectile function and the satisfaction. These factors were evaluated according to different definitions of PE to assess whether the definition used yielded differences in the data. The prevalence of PE, based on a PEDT score of 11, self-reporting and stopwatch-recorded IELT of 1 min was 11.3%, 19.5% and 3%, respectively. The prevalence of PE diagnoses based on PEDT score and self-reporting increased with age, but stopwatch-recorded IELT-based diagnoses did not. Males experiencing PE showed lower levels of libido, erectile function and frequency and satisfaction of sexual intercourse compared with non-PE males. PE males felt that they did not satisfy their partners in terms of the partners’ sexual satisfaction and frequency of orgasm, in comparison with non-PE males. PE is a highly prevalent sexual dysfunction in males. Regardless of whether the PE diagnosis was made on the basis of self-reporting, PEDT score or stopwatch-recorded IELT, subjective symptoms were similar among PE males.
