Men circumcised either as children or adults report less intense sexual pleasure and orgasm than those who are uncircumcised, a new study from Belgium found.
“We’re not saying less sexual activity or satisfaction, but sensitivity,” said the study’s senior researcher Dr Piet Hoebeke, of Ghent University Hospital.
The new study surveyed 1 369 men over the age of 18, who responded to leaflets handed out at train stations across Belgium.
The men were asked whether they were circumcised, and were then asked to rate how sensitive their penis was, how intense their orgasms were and whether they experience any pain or numbness when they are aroused.
Overall, 310 men who took the survey were circumcised, and 1 059 were not. Each rated how sensitive their penis was on a scale from 0 to 5, with higher numbers being the most sensitive.
Overall, uncircumcised men reported between 0.2 points and 0.4 points higher sensitivity and sexual pleasure when their penis’s head – known as the glans – was stroked during arousal, compared with circumcised men.
For example, uncircumcised men reported an average sensitivity score of 3.72 when they or their partner stroked the top part of their penis’s glans, compared with 3.31 among circumcised men.
Uncircumcised men also reported more intense orgasms.
“It’s not a very big difference in sensitivity, but it’s a significant difference,” Hoebeke said.
Some religions and cultures practise circumcision, while other people choose circumcision for possible health benefits – including a reduced risk of urinary tract infections.
Hoebeke and his colleagues write in BJU International that there are few studies researching whether foreskin plays a role in sexual pleasure.
But Dr Aaron Tobian, who studies circumcision but was not part of the new study, said that previous randomised controlled trials – considered the gold standard of medical research – looked at sexual performance and satisfaction. Those studies, he said, did not find a difference.
One possible explanation for any potential difference in sensitivity is that a man’s foreskin may protect his penis’s head from rubbing against underwear. It’s possible, the researchers write, that friction makes the head of the penis thicker, drier and ultimately less sensitive.
The researchers also found circumcised men were more likely to report more pain and numbness during arousal than uncircumcised men, which Hoebeke said was likely due to scar tissue.
“I’m amazed that people report pain during sexual pleasure… That’s very amazing and that was unexpected,” Tobian said.
Tobian, of Johns Hopkins University in Baltimore, said the findings were missing important context. “The medical evidence and the benefits of male circumcision are abundantly clear,” Tobian said.
“If there was a vaccine out there that reduces the risk of HIV by 60 percent, herpes by 30 percent and the penile cancer-causing HPV by 35 percent, the medical community would rally behind it,” said Tobian. - Reuters
