We evaluated the self-reported prevalence of and attitudes toward premature ejaculation (PE) in a community-based study of married couples.A community-based cross-sectional study of PE was conducted among married couples in Gwangju, Korea. Self-reported data were collected through the use of questionnaires, which included demographic questions, the Premature Ejaculation Diagnostic Tool (PEDT), the intravaginal ejaculation latency time (IELT), patient-reported outcome (PRO), and the Female Sexual Function Index (FSFI).Of the 290 couples who completed the survey, the prevalence of PEDT-diagnosed PE including probable PE was 23.7% of men. By IELT measure, the prevalence of PE was 21.7% as reported by the men and 23.9% as reported by their partners, respectively. PRO responses indicated that control over ejaculation and severity of PE were not reported significantly differently by the men and their partners. Satisfaction with sexual intercourse was poorer for the men's partners than for the men. Personal distress and interpersonal difficulty were higher for the men than for their partners. The partners of men in the PE group had significantly lower FSFI scores than did the partners of men in the non-PE group.The reporting of the prevalence of PE did not differ significantly between the men in this study and their partners. However, PE in men tended to impact their partners' sexual function.
