Objective: We aim to investigate the effects of adult male circumcision on PE in men in the Anhui province of China.

Material and Methods: Between December 2009 and March 2014, a prospective field survey was conducted in the Anhui province of China. A total of 575 circumcised men and 623 uncircumcised men (control group) were evaluated. Detailed evaluations (including circumcision and control groups) on PE were conducted before circumcision and at the 3-, 6-, 9- and 12-month follow-up visits after circumcision. The Intravaginal Ejaculatory Latency Time [IELT], Patient-Reported Outcome measures and 5-item version of the International Index of Erectile Function were used to measure the ejaculatory and erectile function for all subjects.

Results. A total of 1,198 males (circumcision group: N=575; control group: N=623) participated in the survey. Of the enrolled participants, 998 (83.31%) males completed the one-year follow-ups. During the one-year follow-up, men experienced higher IELT, and better scores of control over ejaculation, satisfaction with sexual intercourse and severity of PE than men at baseline (P<0.001 for all). Similarly, when compared with the control group, the circumcised men reported significantly improved IELT, control over ejaculation, and satisfaction with sexual intercourse (P<0.001 for all). PE severity in the circumcision group was also lighter than that in control group (P<0.001). Furthermore, circumcision was significantly associated with PE at the 3-, 6-, 9- and 12-month follow-ups.

Conclusion. Circumcision might have positive effects on IELT, ejaculatory control, sexual satisfaction and PE severity. In addition, circumcision was significantly associated with PE.
