In a report of a current study, it was shown that there are no differences in penile sensitivity for a variety of stimulus types and penile sites between circumcised and intact men. Paying attention on health results, protection against sexually transmitted infections, despite penile sensitivity, the American policy statement supports routine circumcision of newborn males, while the Canadian policy denies it.

"We directly tested whether circumcision have any relation with a reduction in penile sensitivity by testing tactile detection, pain, warmth detection, and heat pain thresholds at multiple sites on the penis between groups of healthy (neonatally) circumcised and intact men," explained lead author Jennifer Bossio from the Queen's University.

She also said that this study indicates that neonatal circumcision has no relation with changes in penile sensitivity and provides preliminary evidence to suggest that the foreskin is not the most sensitive part of the penis. "Methodology and results from this study build on previous research and imply that if sexual functioning is related to circumcision status, this relationship is not a combination  the result of decreased penile sensitivity stemming from neonatal circumcision," observed Ms. Bossio.
