Male circumcision decreases penile sensitivity as measured in a large cohort

Objectives • To test the hypothesis that sensitivity of the foreskin is a substantial part of male penile sensitivity. • To determine the effects of male circumcision on penile sensitivity in a large sample. Subjects and Methods • The study aimed at a sample size of ª1000 men. • Given the intimate nature of the questions and the intended large sample size, the authors decided to create an online survey. • Respondents were recruited by means of leaflets and advertising. Results • The analysis sample consisted of 1059 uncircumcised and 310 circumcised men. • For the glans penis, circumcised men reported decreased sexual pleasure and lower orgasm intensity. They also stated more effort was required to achieve orgasm, and a higher percentage of them experienced unusual sensations (burning, prickling, itching, or tingling and numbness of the glans penis). • For the penile shaft a higher percentage of circumcised men described discomfort and pain, numbness and unusual sensations. • In comparison to men circumcised before puberty, men circumcised during adolescence or later indicated less sexual pleasure at the glans penis, and a higher percentage of them reported discomfort or pain and unusual sensations at the penile shaft. Conclusions • This study confirms the importance of the foreskin for penile sensitivity, overall sexual satisfaction, and penile functioning. • Furthermore, this study shows that a higher percentage of circumcised men experience discomfort or pain and unusual sensations as compared with the uncircumcised population. • Before circumcision without medical indication, adult men, and parents considering circumcision of their sons, should be informed of the importance of the foreskin in male sexuality
