Brief summary

The purpose of the study is to characterize intravaginal ejaculatory latency time (time between the start of vaginal intercourse and the start of intravaginal ejaculation) in men with and without premature ejaculation (PE) and to assess the validity of patient-reported outcomes.

Detailed description

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 intravaginal ejaculatory latency time (IELT) during intercourse. At visits during the observation period patients (and/or partners if partners are responsible for completing questionaires) 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 IELT values for men with PE and men without PE.

Design outcomes

Primary

MeasureTime frameDescription
Change in Intravaginal Ejaculatory Latency Time (IELT)Day 1 to Week 8Estimated distribution of the average IELT for both the premature ejaculation (PE) and non-PE populations will be calculated.
Change in Patient-Reported Outcomes (PRO)Week 4 and Week 8Additional evidence of reliability and validity of PROs for patients with and without PE and their partners will be expolred. The PROs will include different parameters related to (control over ejaculation, satisfaction with sexual intercourse, personal distress, and interpersonal difficulty).

Secondary

MeasureTime frameDescription
Association between intravaginal ejaculatory latency time (IELT) and patient reportedout comes (PROs)Up to Week 8Association between IELT and PROs used in this study will be explored.
Utility of the Male Sexual Function Scale and Ejaculation QuestionnairesDay 1The study will explore utility of the Male Sexual Function Scale and Ejaculation Questionnaire as screening instruments.
PROs and IELT as indicators to clasify PE status.Up to Week 8The study will evaluate the ability of PROs and IELT to classify PE status
