A 2011 Danish survey of around 5,000 men and women, led by epidemiologist Morten Frisch, reported that circumcised men were more likely to have difficulty reaching orgasm and that their female partners more often reported sexual dissatisfaction and discomfort.
We report this as what it is: one large observational study, not the final word. Its findings have been praised by some researchers and contested by others, and survey data can't fully separate correlation from cause.
AntiCirc's view: even setting the disputed numbers aside, the study asks the right question. The foreskin is functional tissue with a role in sensation and natural lubrication — "what does removing it cost?" deserves serious study rather than reflexive dismissal.
In 2011, the Danish epidemiologist Morten Frisch and colleagues published, in the International Journal of Epidemiology, one of the first large studies to ask not only how circumcision affects men but how it affects their partners. Drawing on responses from around 5,000 Danish men and women, and reported at the time by ScienceNordic, the survey found that circumcised men were more likely to report difficulty reaching orgasm, and their female partners more likely to report dissatisfaction and discomfort during sex.
What the study reported
By the study's account, circumcised men were markedly more likely to experience frequent difficulty reaching orgasm, and their partners reported a higher rate of unmet sexual needs and discomfort. The researchers proposed plausible mechanisms — reduced sensitivity of the exposed and keratinised glans, and the loss of the foreskin's natural gliding motion, which can mean more friction for both partners. It was among the first attempts to measure circumcision's effect on women at all, an oddly neglected question given how often the procedure is framed as harmless.
The case for caution about the findings
This is one large observational study, not the final word, and we treat it as such. Cross-sectional survey data cannot fully separate correlation from cause; cultural, religious and behavioural differences between circumcised and uncircumcised groups are hard to disentangle. The findings were also sharply contested: other researchers published rebuttals questioning the methods and conclusions, and the debate has never fully resolved. A reader should take the results as a serious signal worth investigating, not a proven verdict.
Why the question deserves study
What the study does well is ask a question the field has too often waved away. The foreskin is functional tissue with a role in sensation and natural lubrication; some other research has reported the foreskin and its rim to be among the more touch-sensitive parts of the penis. Whether removing that tissue carries a sexual cost is a legitimate empirical question — and the honest scientific response is to investigate it rigorously rather than to dismiss it because the answer is uncomfortable.
Our view
Even setting the disputed numbers entirely aside, a principle remains. A healthy, functioning part of the body — one with a plausible role in sexual experience — should not be removed from someone who never got to weigh that trade-off for himself. The uncertainty cuts in favour of leaving the choice to the person whose body, and whose sex life, it is.
