Scientific Studies“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.”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.The glans of the circumcised penis is less sensitive to fine touch than the glans of the uncircumcised penis. The transitional region from the external to the internal prepuce is the most sensitive region of the uncircumcised penis and more sensitive than the most sensitive region of the circumcised penis. Circumcision ablates the most sensitive parts of the penis.Circumcised penises require a greater than 10-fold increase of force to penetrate the vagina compared to uncircumcised penises.Women have a dramatically higher rate of vaginal and multiple orgasms with intact partners versus circumcised partners. In sexually experienced adult men who had undergone circumcision reported “[t]he reduction in erectile function was statistically significant. Some men were unable to have erection after the procedure but even those who were able to have sex with the same partner before and after the procedure reported worsened erectile function. This difference remained significant when adjusted for age and co-morbidities. Some comments were: ‘Erections are shorter time now.’ ‘Penis smaller. Now have erectile dysfunction.'”
