Objective: Premature ejaculation (PE) has detrimental social and psychological effects on the quality of life of affected individuals. We conducted this study to comprehensively evaluate the clinical features of patients with PE.

Material and Methods: From March 2017 to June 2017, a total of 1128 consecutive men with PE and their female sexual partners were enrolled from 16 medical institutions in China. Each of them completed a detailed questionnaire on demographics information, sexual and medical histories, International Index of Erectile Function (IIEF) score, and premature ejaculation diagnostic tool (PEDT).

Results: The mean ages and BMI of PE patients were 33.96±8.05 years and 23.81±3.20Kg/m2. The sexual function of each patient with PE was assessed according to a detailed questionnaire (Mean PEDT score: 14.55±3.72; Mean IELT: 1.60±0.85 min; Mean IIEF score: 16.04±5.83). Percentage of mild, moderate and severe ED in patients with PE was 56.56%, 14.89% and 9.93%, respectively. The social and psychological effects of PE were evaluated further and 79.61% of the men feel dissatisfied with PE. 47.70%and 17.82% complained that they cannot prolong intra-vaginal ejaculation latency time or control the frequency of inserting into the vaginal. Moreover, 52.93% of the female sexual partners felt dissatisfied with PE. And 17.20% complained that they cannot get orgasm during sexual intercourse. Furthermore, 66.22% female sexual partners expected improvements after PE treatment. In addition, 32.54% couples both felt dissatisfied with PE.

Conclusions: PE is a shared health problem for both the men and their female sexual partners. Evaluating the clinical features and understanding expectation of PE patients and their female sexual partners is necessary for clinical practice.
