A new study suggests that uncircumcised men may enjoy four times more penile sensitivity than circumcised men. This is according to the Fine-touch Pressure Thresholds in the Adult Penis article published in the British Journal of Urology International last week.
The study was conducted to map fine-touch pressure thresholds of the adult penis in circumcised and uncircumcised males and to compare the two populations. Researchers measured fine-touch sensitivity of the penis at 17 specific sites on the intact (uncircumcised) penis and the remaining nine sites plus two scar sites on the circumcised penis.
The results surprised the research team, according to Morris Sorrells, MD, lead researcher, who said, “The most sensitive part of the penis is the preputial opening. The results confirmed that the frenulum and ridged band of the inner foreskin are highly erogenous structures that are routinely removed by circumcision, leaving the penis with one-fourth the fine-touch sensitivity it originally possessed.”
Five sites on the penis-all regularly removed by circumcision-are more sensitive than the most sensitive site remaining on the circumcised penis. Researcher pediatrician and statistician Robert Van Howe said, “Oddly, the most sensitive site on the circumcised penis is the circumcision scar itself.”
159 subjects in the USA were enrolled in the study. The authors do temper their conclusions by saying that the measurement of fine touch using pressure thresholds might be limited, but they say that their study “provides a baseline for future comparison studies.”
These findings come several decades after Masters & Johnson said there is no sensitivity difference in a circumcised and a uncircumcised penis.
