peer reviewed ; Physiological, behavioral, cognitive, and emotional factors are generally acknowledged to play a role in premature ejaculation (PE). However, the nature and the extent of their etiological impact remain largely imprecise. The present study examined functional and psychometric dynamics at work in a PE population. A total of 461 men with PE and 80 partners completed an online questionnaire. The main outcome measures were self-reported ejaculatory latency time, the feeling of control upon ejaculation, sexual satisfaction, distress related to PE, trait anxiety (STAI-B), sexual cognitions (SIQ), social anxiety (LSAS and SISST), and personality traits (TCI-R). In our sample, the median latency time to ejaculation was between 1 and 2 minutes. Sexual satisfaction and distress correlated more strongly with the feeling of control than with the self-reported latency time. Men experienced more distress and dissatisfaction related to PE than did their partners while overestimating their partners’ distress and dissatisfaction. PE participants’ scores differed significantly, albeit slightly, from STAI-B, SIQ, LSAS, and SISST norms. The differences were negligible on TCI-R. Some differences became stronger when subtypes were considered. Participants combining generalized and lifelong PE with self-reported latency times of < 30 sec reported lower sexual satisfaction and control, higher distress, higher social anxiety, and harm avoidance (TCI-R/HA) scores. By contrast, the situational subtype of PE was found to be characterized by a higher level of satisfaction, a greater feeling of control, less distress, and higher trait anxiety scores. However, the trends remained statistically discrete. ; BibliothEP
