Premature ejaculation (PE) is a form of male sexual dysfunction. In the assessment of PE, an objective measurement is the intravaginal ejaculatory latency time (IELT); subjective measures include ejaculatory control and satisfaction with sexual intercourse. This is a multinational, multicenter, observational study in men with and without PE. The study consists of three visits: one visit for screening and enrollment, and two visits for observation after 1 and 2 months (total duration of 8 weeks). No study treatment for PE is administered to patients during the course of the study. Patients and their partners are expected to attempt sexual intercourse at least 2 times a week during the 8-week study period and to use a stopwatch to record the IELT during intercourse. At visits during the observation period they also provide patient-reported outcomes (PROs) by answering several questionnaires that include the topics of control over ejaculation, satisfaction with sexual intercourse, personal distress, interpersonal difficulty, and self-esteem. The study will estimate the distribution of the average intravaginal ejaculatory latency time values for men with PE and men without PE.

No study treatments are administered.
