Objective: To prospectively study, using a questionnaire, the sexuality of men circumcised as adults compared to uncircumcised men, and to compare their sex lives before and after circumcision.
Subjects and methods: The study included 373 sexually active men, of whom 255 were circumcised and 118 were not. Of the 255 circumcised men, 138 had been sexually active before circumcision, and all were circumcised at >20 years of age. As the Brief Male Sexual Function Inventory does not specifically address the quality of sex life, questions were added to compare sexual and masturbatory pleasure before and after circumcision.
Results: There were no significant differences in sexual drive, erection, ejaculation, and ejaculation latency time between circumcised and uncircumcised men. Masturbatory pleasure decreased after circumcision in 48% of the respondents, while 8% reported increased pleasure. Masturbatory difficulty increased after circumcision in 63% of the respondents but was easier in 37%. About 6% answered that their sex lives improved, while 20% reported a worse sex life after circumcision.
Conclusion: There was a decrease in masturbatory pleasure and sexual enjoyment after circumcision, indicating that adult circumcision adversely affects sexual function in many men, possibly because of complications of the surgery and a loss of nerve endings.
