Circumcision and Sexual Function

Summary of Research Results

Male Circumcision does not effect Sexual Function

In spite of the claims often made by those who oppose the procedure, circumcision does not negatively effect sexual function for the man, and/or diminish sexual pleasure in the partner. This has been scientifically corroborated by several medical research articles, some of which are discussed below.

In a study done in Uganda in 2009, researchers studied 455 partners of men in Uganda who were recently circumcised. Nearly 40% said sex was more satisfying afterward. About 57% reported no change in sexual satisfaction, and only 3% said sex was less satisfying after their partner was circumcised (see here for further information).

When some men who were circumcised as adults in Africa were asked about the change in sexual function, most men reported no difference, a small percentage report that it's worse, and a small percentage report that it's better.

    OBJECTIVE: Despite biological advantages of male circumcision in reducing HIV/sexually transmitted infection acquisition, concern is often expressed that it may reduce sexual enjoyment and function. We examine the association between circumcision and sexual function among sexually active men in Britain using data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3). Natsal-3 asked about circumcision and included a validated measure of sexual function, the Natsal-SF, which takes into account not only sexual difficulties but also the relationship context and overall level of satisfaction. METHODS: A stratified probability survey of 6293 men and 8869 women aged 16-74 years, resident in Britain, undertaken 2010-2012, using computer-assisted face-to-face interviewing with computer-assisted self-interview for the more sensitive questions. Logistic regression was used to calculate odds atios (ORs) to examine the association between reporting male circumcision and aspects of sexual function among sexually active men (n?=?4816).

    RESULTS: The prevalence of male circumcision in Britain was 20.7% [95% confidence interval (CI): 19.3-21.8]. There was no association between male circumcision and, being in the lowest quintile of scores for the Natsal-SF, an indicator of poorer sexual function (adjusted OR: 0.95, 95% CI: 0.76-1.18). Circumcised men were as likely as uncircumcised men to report the specific sexual difficulties asked about in Natsal-3, except that a larger proportion of circumcised men reported erectile difficulties. This association was of borderline statistical significance after adjusting for age and relationship status (adjusted OR: 1.27, 95% CI: 0.99-1.63).


    Data from a large, nationally representative British survey suggest that circumcision is not associated with men's overall sexual function at a population level.

  2. Male Circumcision Does Not Reduce Sexual Function, Sensitivity or Satisfaction.

    Advances in Sexual Medicine, 5, 53-60. doi: 10.4236/asm.2015.53007

    Abstract: We disagree with Boyle's recent article questioning our systematic review in Journal of Sexual Medicine in 2013 (Volume 10, pages 2644-2657). In particular, he disputed the quality ranking we assigned to 7 of the 36 articles that met our inclusion criteria. These had been ranked for quality by the Scottish Intercollegiate Guidelines Network (SIGN) grading system. We found that, "the highest-quality studies suggest that medical male circumcision has no adverse effect on sexual function, sensitivity, sexual sensation or satisfaction." This conclusion was supported by two randomized controlled trials, regarded as high-quality (1++) evidence and the majority of surveys and studies involving physiological measurements comparing uncircumcised and circumcised men. Here we explain why the 2 randomized controlled trials merit a 1++ ranking and why 4 reports that Boyle believes merit a higher ranking only meet the criteria set down for low quality (2-) evidence according to the SIGN system. We therefore stand by our conclusions. These are supported by a meta-analysis of sexual dysfunctions and by a recent detailed systematic review of the histological correlates of male sexual sensation.

  3. Histological Correlates of Penile Sexual Sensation: Does Circumcision Make a Difference?

    Abstract: The question of whether removal of sensory receptors in the prepuce by circumcision affects sensitivity and/or sexual pleasure is often debated.
    To examine histological correlates relevant to penile sensitivity and sexual pleasure. Methods Systematic review of the scientific literature on penile structures that might affect sensitivity and sexual sensation. Articles were included if they contained original data on human male penile histology or anatomy. Individual articles, including reference lists, were evaluated. They were then considered in relation to physiological data from articles retrieved by a previous systematic review.
    Results: Results: We retrieved 41 publications on penile structure. Considered in the light of 12 reporting physiological measurements, our evaluation finds that sexual response is unlikely to involve Meissner's corpuscles, whose density in the prepuce diminishes at the time of life when male sexual activity is increasing. Free nerve endings also show no correlation with sexual response. Because tactile sensitivity of the glans decreases with sexual arousal, it is unrelated to sexual sensation. Thermal sensitivity seems part of the reward mechanism of intercourse. Vibrational sensitivity is not related to circumcision tatus. Observations that penile sexual sensation is higher post circumcision are consistent with greater access of genital corpuscles to sexual stimuli after removal of the prepuce. This is based on the distribution of these corpuscles (which are located in the glans) and, in uncircumcised men, the position of the retracted prepuce during intercourse, rather than any change in the number of genital corpuscles. The scientific literature suggests that any sexual effect of circumcised men may depend solely on exposure of the glans and not on the absence of the prepuce.


    Based on histological findings and correlates of sexual function, loss of the prepuce by circumcision would appear to have no adverse effect on sexual pleasure. Our evaluation supports overall findings from physiological measurements and survey data.

    Abstract: < 0.001 for all). Similarly, when compared with the control group, the circumcised men reported significantly improved IELT, control over ejaculation, and satisfaction with sexual intercourse (P < 0.001 for all). These findings suggested that circumcision might have positive effects on IELT, ejaculatory control, sexual satisfaction, and PE severity. In addition, circumcision was not significantly associated with the development of PE.
