The Foreskin, Circumcision and Sexuality
No good scientific work has been done on the effect of circumcision on sexual function, but it is repeatedly stated that
For example in "Babywatching", Desmond Morris says circumcision "has no effect, one way or the other, on the sexual performance of the adult male." Books for young people, especially, protest too much, such at the British Family Planning Association's "How Sex Works": "Whether you have a foreskin or not will not affect your sexual health in the future."
This claim flies in the face of common sense. The foreskin is ideally placed to both give and receive sexual stimulation, and it would be extraordinary if it did not. It has been known since antiquity that the foreskin gives pleasure, only forgotten in the US in the last century or so.
This study shows that the foreskin is the most touch-sensitive part of the penis:

Van Howe BJU International 99 (4), 864-869 (British Journal of Urology International, Circumcision removes the most sensitive part of a man's penis. Sorrells and others enlisted 159 men from the San Francisco Bay area, 91 of them circumcised, and conducted touch-sensitivity tests, using instruments that press with calibrated hairs, on 11 or 17 different places on their penises. The men could not see where they were being touched. ![]() Larger image

This study will doubtless be criticised because its authors are Intactivists, but carrying out such studies take considerable dedication, so few who conduct them can be completely without involvement, and the data is there to be checked for accuracy. (Just getting ethical approval is a major hurdle, even though circumcision itself has never had ethical approval.) "Extraordinary claims demand extraordinary proof," but this study only demonstrates what should be obvious. The value of this study is that it is much more thorough and less biased in its design toward circumcision than the ones below. More studies are needed to establish the link between touch-sensitivity and sexual pleasure, but it should be obvious to most men.
One of the circumcised experimental subjects reports on the experience.
A presentation was given at the World Association of Sexuality Congress in Sydney in April 2007, contrasting the Sorrells study with the Masters & Johnson study that follows. A large poster accompanying the presentation can be downloaded (pdf, 3.2MB).
The entire basis of the claim that circumcision has no effect on sexuality was until recently an "experiment" performed over 40 years ago by William H. Masters MD and Virginia E. Johnson and reported in their 1966 best-seller, "Human Sexual Response". Their bias toward circumcision and their ignorance of the intact penis are manifest.

Their first picture, of the "normal" anatomy, shows no sign of a foreskin. ![]() FIGURE 12-1 The penis: normal anatomy (lateral view). (p 177) What is labelled "coronal ridge" looks more like a circumcision scar. The corona (glandis) is actually the high point to the left of that. Their next picture shows the foreskin but does not identify it. ![]() FIGURE 12-3 Male pelvis: normal anatomy (lateral view). (p 180) The corona glandis is misidentified. The next four drawings are similar to this one: ![]() FIGURE 12-4 Male pelvis: excitement phase. (p 182) They look as though someone unfamiliar with the foreskin added it to a diagram of a circumcised penis, but it is still not identified. None of the pictures of erections show that the foreskin can retract, or how. Thank heaven an erection is (usually) "Reversible"! This is actually a picture of a dissected penis (from below) with all skin removed: ![]() FIGURE 12-8 The penis: erect (ventral view). (p 187) Masters and Johnson's bias towards circumcision is further shown by their table 2-6
p 17 and table 2-8
p 18 This belies any claim to objectivity. Their discussion of circumcision (pp 189-190) begins with a claim that because only 16 (actually 9 according to their own table) of the 231 men aged 21-40 were intact (compared to 26 of the 81 older men), there was "a medical trend toward urging routine circumcision of the newborn male infant." This ignores males under 21, and hence the most recent 21 years of medical history. They also assume their sample of 315 volunteers (who were comfortable having sex in front of the experimenters) was representative of the whole population of the US, and the 35 intact ones representative of all intact men. They continue (in prose famous for its obscurity and ugliness): The phallic fallacy that the uncircumcised male can establish ejaculatory control more effectively than his circumcised counterpart was accepted almost universally as biologic fact by both circumcised and uncircumcised male study subjects. [The popular press at the time was widely claiming the reverse. Magazines like Penthouse were suggesting that intact men with premature ejaculation might get circumcised to prevent it.] This concept was founded on the widespread misconception that the circumcised penile glans is more sensitive to the exteroceptive [ie, from outside] stimuli of coition or masturbation than is the glans protected by the residual foreskin. [A misconception indeed! "Residual" is a prejudiced way of saying "intact". All involved in this fallacy seem to have been unaware that the foreskin can retract. Masters and Johnson ignore the possiblity that the foreskin itself is involved in sexual sensation.] Therefore, the circumcised male has been presumed to have more difficulty with ejaculatory control and (as many study subjects believed) a greater tendency towards impotence. A limited number of the male study-subject population was exposed to a brief clinical experiment designed to disprove [Real scientists aim to test, not prove or disprove] the false premise [If it had not yet been disproved, how did they know it was false?] of excessive sensitivity of the circumcised glans. The 35 uncircumcised males were matched at random with circumcised study subjects of similar ages. Routine neurologic testing for both exteroceptive and light tactile discrimination were conducted on the ventral and dorsal surfaces of the penile body, with particular attention directed toward the glans. [No further details are given as to the nature of these tests and it has proved impossible to find out. It is unclear what "particular attention" means. It goes without saying that no attention was given to the foreskin, nor could it be with the circumcised "male study subjects".] No clinically significant difference could be established between the circumcised and the uncircumcised glans during these examinations. [Surprise! Masters and Johnson didn't find what they weren't looking for. NB: this testing was purely for the sense of touch. It had nothing to do with sex.] An elaborate explanation of this "finding" follows, based on Masters and Johnson's observation that 29 out of the 35 "uncircumcised male study subjects" had foreskins that retracted during intercourse. They were apparently previously unaware that foreskins usually retract. This is linked to a later (p197) discussion of "automanipulation" (masturbation): Uncircumcised males have not been observed to concentrate specifically on the glans area of the penis. [Of course not! They were playing with their much more sensitive foreskins but Masters and Johnson failed to notice that.] Normally they follow the usual pattern of confining manipulative activity entirely to the penile shaft [of which the foreskin is an integral part]. Stroking techniques rarely move sufficiently distal on the shaft of the penis to encounter more than the coronal ridge of the glans even late in plateau phase just before ejaculation. [The coronal ridge is quite sufficient, forming an anvil on which to rub the foreskin.] Masters and Johnson conspicuously fail to notice a common technique of intact men, of using only one or two fingers and the thumb to move the foreskin on and off the glans - which contrasts sharply with the furious grasping, squeezing and grinding of the shaft and glans by circumcised men. Masters and Johnson's only interest in the foreskin in intercourse is whether it covers the glans: This is obviously a different picture from that occasioned by active intercourse. With full vaginal containment the foreskin not tightly attached to subjacent tissue usually retracts freely from a major portion of the glans during active male coital thrusting before ejaculation. |
On this is based the whole of the case that "circumcision has no effect on sexual function."
In "Dear Dr HIPPocrates", Dr Eugene Schoenfeld elaborates it to
"As for the question of decreased sensitivity of the glans, Masters and Johnson studied this question in their researches into the physiology of sex. Extensive neurological testing of such sensations as touch and pain sensitivity failed to reveal any differences in those with and without foreskins."
In "Healthy Sex" by Miriam Stoppard (Dorling Kindersley), the claim about a myth of greater control by intact men, and the alleged reason for it, is paraphrased almost verbatim, without acknowledgement.
The claim of "no effect" was quoted as recently as February 2002 in the American Association of Family Physicians' Policy Statement.
In sharp contrast is the importance Masters and Johnson attach to the role of the clitoral hood (female prepuce) in intercourse:
A mechanical traction develops on both sides of the clitoral hood of the minor labia subsequent to penile distention of the vaginal outlet. With active penile thrusting, the clitoral body is pulled downward toward the pudendum [Masters and Johnson define the "pudendum" as "the mons pubis, labia majora, labia minora, and the vestibule of the vagina".] by traction exerted on the wings of the clitoral hood....
When the penile shaft is in the withdrawal phase of active coital stroking, traction on the clitoral hood is somewhat relieved and the body and glans return to normal pudendal-overhang positioning....
... If the vaginal outlet is too expanded to allow strong traction on the minor-labial hood by the thrusting penis, minimal clitoral excursion will occur and little if any secondary stimulation will develop.
- p.58 But the role they attach to the female prepuce is still a passive one, and they do not consider the possibility that it may be the source of erotic sensation in its own right, either.
In "The Hite Report" (Dell/Summit, 1977, p. 271) and "The New Hite Report", Shere Hite grants the importance of the role of the clitoral hood, but pours scorn on Masters and Johnson's emphasis on the role of "active penile thrusting" calling it "a Rube Goldberg model".
In response to an enquiry about the role of the clitoral hood, "Charlou" at RichardDawkins.net wrote:

A more recent study makes the same mistake, perhaps more glaringly. Abstract of a paper presented at a meeting of the American Urological Association in Chicago on April 29, 2003.
EFFECTS OF CIRCUMCISION ON MALE PENILE SENSITIVITYClifford B Bleustein*, Haftan Eckholdt, Joseph C Arezzo, Arnold Melman, Bronx, NY Introduction and Objective: Controversy continues to exist about the effect of circumcision on penile sensitivity and sexual satisfaction. This study was designed to evaluate penile sensitivity in both circumcised and uncircumcised males. We evaluated both large and small axon nerve fibers using vibration, pressure, spatial perception, and warm and cold thermal thresholds. Measurements both in functional men and men with erectile dysfunction (ED) were obtained to evaluate for differences in penile sensitivities.

J Sex Med. 2007 Apr 6; [Epub ahead of print] Sensation and Sexual Arousal in Circumcised and Uncircumcised Men.Payne K, Thaler L, Kukkonen T, Carrier S, Binik Y.
Introduction. Research, theory, and popular belief all suggest that penile sensation is greater in the uncircumcised as compared with the circumcised man. However, research involving direct measurement of penile sensation has been undertaken only in sexually functional and dysfunctional groups, and as a correlate of sexual behavior. There are no reports of penile sensation in sexually aroused subjects, and it is not known how arousal affects sensation. In principle, this should be more closely related to actual sexual function. Aim. This study therefore compared genital and nongenital sensation as a function of sexual arousal in circumcised and uncircumcised men. Methods. Twenty uncircumcised men and an equal number of age-matched circumcised participants underwent genital and nongenital sensory testing at baseline and in response to erotic and control stimulus films. Touch and pain thresholds were assessed on the penile shaft, the glans penis, [but not the foreskin] and the volar surface of the forearm. [volar = of the palm - meaning upper when the palm is up?] Sexual arousal was assessed via thermal imaging [of one small region] of the penis. Results. In response to the erotic stimulus, both groups evidenced a significant increase in penile temperature, which correlated highly with subjective reports of sexual arousal. Uncircumcised men had significantly lower penile temperature than circumcised men, and evidenced a larger increase in penile temperature with sexual arousal. ![]() [This is news, suggesting the foreskin functions as a radiator - but the surface of the one small region of the penis they measured, "just below {proximal to?} the glans penis, adjacent to the coronal ridge on the lateral right surface of the penile shaft" is skin on the intact man, but may be mucosa on the circumcised. Since they ignore the foreskin, they also ignore the fact that the foreskin rolls back on arousal, so that mucosa is exposed on both.] No differences in genital sensitivity were found between the uncircumcised and circumcised groups. Uncircumcised men were less sensitive to touch on the forearm than circumcised men [Suggesting overall hypersensitivity is a long-term consequence of circumcision?]. A decrease in overall touch sensitivity was observed in both groups with exposure to the erotic film as compared with either baseline or control stimulus film conditions. No significant effect was found for pain sensitivity. Conclusion. These results do not support the hypothesized penile sensory differences associated with circumcision [so long as you ignore the foreskin]. However, group differences in penile temperature and sexual response were found.

So what effect does the foreskin have?
Central to Intactivist claims about foreskin function in sex is the work of Taylor et al., demonstrating that the foreskin itself is richly innervated with Meissner corpuscles, which are sensitive to light touch. They make the foreskin's sensitivity comparable to that of the fingertips or the lips (but probably less than that of the tip of the tongue or the eyelashes)
The ridged band now has its own website, hosted by its discoverer, Dr John Taylor.
... the type, not just the amount, of skin lost to routine male circumcision is often overlooked. Anatomically and physiologically, the skin of the penis is designed to activate the male sexual reflex mechanism. To perform this interesting function it is richly endowed with smooth muscle fibres that cause its upper, (sexual contact) surface to 'firm up' and wrinkle - and become much more frictional - during erection. During vaginal intromission these conformational changes in penile skin ensure stretching of ridged band and reflex contraction of bulb muscles . In short, the penile skin behaves in exactly the same way, during erection, as scrotal skin. Almost certainly, uniquely-structuresd penile and scrotal skin play an important role in activating and moderating erogenous sensation and sexual reflexes for ejacuation. As far as I know, there is no female equivalent. In short, male circumcision completely alters the way male sexual sensations and reflexes are generated during vaginal intercourse. - John Taylor |
Contrary to Masters and Johnson's thoroughly confused and confusing discussion, removal of the foreskin does affect the surface of the glans. It becomes keratanised, covered in a hardened coating. This shields the nerves of the glans from stimulation.
These two effects together combine to change the quality, and reduce the quantity, of sensitivity of circumcised men. The neurology has not been studied in detail, but other work suggests that when nerves are severed in infancy they reconfigure themselves, so that men circumcised in infancy find pleasure in stimulation of the glans (for which it was not designed/did not evolve) that intact men do not. This suggests that men circumcised in adulthood react differently from men circumcised as babies:
Immediately after circumcision, the nerves of the glans bombard the brain with the new sense impressions they are constantly receiving, which the brain interprets as pain. (Newly circumcised men are advised to wear loose clothing - none if this is practicable.) This fades over time. One reason will be that the brain learns to disregard these signals, like any other constant sensation. They have been called "false alarms".
That explains why infant-circumcised (but not adult-circumcised) men commonly say
"I couldn't cope with any more sensitivity than I have now."
- most recently Larry David, former co-author of Seinfeld, to Dustin Hoffman, in connection with the proposed circumcision of Hoffman's grandson.
The sensitivity they have left, from their glanses, and which intact men do not experience as pleasure, is closely allied to pain. This would also suggest that circumcised men have a more hair-trigger kind of sensitivity. Having fewer nerves available to stimulate the centres that lead to ejaculation and orgasm, the ones they have must work harder. Thus it could well be true that "the circumcised male has more difficulty with ejaculatory control."|
Marilyn Milos writes:
|
This also suggests a mechanism for what has often been noted informally, that circumcised men are more goal-oriented about sex. Getting to orgasm is more important than any pleasures to be had on the way. The nervous connection between stimulation and arousal is so thin (the "bandwidth" is so low, if you like) that the level of stimulation has to be high and uninterrupted to reach orgasm at all. Thus circumcised men can only relax and enjoy sex when orgasm has been reached, and orgasm is something that has to be achieved, it may not be pleasurably delayed. (A sex manual of 1961, "The Marriage Art" by John D. Eichenlaub, nowhere mentions the foreskin, but recommends that a woman apply ice to her partner's perineum for a special thrill.)
Circumcised men commonly find their frenulum (that is, whatever remnant of their ridged band was left on them) to be the most sensitive part of their penis. Many sex manuals assume this is true for all men. None has questioned why sexual sensitivity should be so concentrated.
So what is the role of the foreskin in intercourse?
The movement of the foreskin is unique. On the in-stroke of intercourse, considered from the point of view of its stationary outer layer, the inner layer rolls outward and applies itself to the vagina. The ridged band engages with the internal ridges of the vagina. On the out-stroke, that movement reverses. Depending on the various dimensions and techniques used, there is considerable variation from that basic pattern and the two sets of ridges may then rub over each other like clothes on an old-fashioned washboard. That might be painful for women if the foreskin were dry like the circumcised penis. Instead, the effect is pleasurable.
An intact man comments on this:
What happens with me is that during entry into the vagina, the labia minora (inner vaginal lips) catches the foreskin and retracts it behind the ridge of the glans. That's where it stays until intercourse is complete and the erection subsides. My partner tells me that this is the normal course of events if the foreskin does not retract on its' own when it becomes erect. The labia minora are so shaped as to catch under the edge of the foreskin, which is usually partially retracted, and push it back. The exposed glans is then exposed to the full friction of the vaginal walls when thrusting. |
Moderate stretching of the foreskin may also be pleasurable for the man. This gives rise to the "balloon job" - inflating the foreskin - possible only for an intact man. (Air should not be forced down the urethra, and on no account should high-pressure air supplies be used.)
Like Masters and Johnson, the Laumann study "Circumcision in the United States: prevalence, prophylactic effects, and sexual practice" is widely misrepresented as "showing that circumcised men enjoy more varied sexual practices and less sexual dysfunction than intact men." It was extracted from a much larger study that was not designed to study circumcision. It relied on self-reporting to determine circumcision status. Self-reporting has been shown to be remarkably inaccurate in other studies. In statements that have been much more widely broadcast than the original study, Edward Laumann himself misquoted his own study: "We were quite surprised to see such clear evidence, at least within the white population, that masturbation was correlated with being circumcised as well as engaging in oral sex and anal sex." The reference to the white population is usually left out. The reference to anal sex is false. This CNN report later says "Circumcised men were found to be nearly 1.4 times more likely [as likely] to engage in heterosexual oral sex than uncircumcised men, the study reported. They also were more likely to have had homosexual oral sex and heterosexual anal intercourse." The only significant results of the study are: Masturbation
Heterosexual oral sex
Homosexual oral sex
Heterosexual anal sex
Notice that the actual differences are quite small, or in the case of homosexual oral sex, the actual prevalence is small. They are quoted as if ALL circumcised men have much more of ALL the practices than ANY intact man. To draw any conclusions from these results, whether "circumcision makes men enjoy sex more" or "circumcised men desparately seek out more varied practices to make up for what they have lost", is beside the point when the data are so weak. Sexual dysfunction CNN: "The study found circumcised men have a slightly lower risk of sexual dysfunction, especially later in life." WRONG: The study found circumcised men over 44 are somewhat less likely to report certain kinds of sexual dysfunction, but not others, than intact men over 44 - but that kind of result doesn't make headlines. The study asked the men if they had ever experienced "lack of interest in sex, unable to ejaculate, ejaculated prematurely, experienced pain during sex, did not enjoy sex, was anxious about performance, had trouble achieving/maintaining erection". (Some of those categories overlap: a man who experienced pain during sex would probably not enjoy sex, for example.) Only in men aged 45-59 (N=340) were there any significant differences:
The measure "had any dysfunction" - apparently a summation of the others - was significant only for the 45-59 age group (58% of the intact men vs 40% of the circumcised men). It needs some explaining why cutting part of the penis off could make it easier to achieve or maintain an erection, but no explanation is forthcoming. For the actual study, see http://www.cirp.org/library/general/laumann/ |
Men cut as adults:
|
AlterNet Uncut is better I have proofby ashkewoof Uncut by birth, got cut at 18 because I was confused that cut penises looked better. I have tried to live without regret and I swore when I got circumcised, I would never regret it. I now live with that regret. I am reminded of this regret every time I am intimate with a partner. With my foreskin went a wonderful degree of sensuality and sensitivity that I will never get back and never knew I would miss until it was gone. I had a whole lot of experience with a foreskin before I was cut and a whole lot of experience without one after I was cut. I am in a very good position to speak on the subject clearly since I have experienced both sides of the issue for long periods of time. I want to scream when I hear parents making the choice to mutilate their child for cleanliness, aesthetics or misplaced notions of health. With a few necessary medical exceptions, this is barbarity and it is mutilating your son in the most intimate of ways. My penis was always clean, happy and wonderful. Now part of it, a truly wonderful part of it is gone and restoration will not bring it back. Stop butchering your children and STOP making this choice for them! It should be illegal to do this to children. If they want to do so later on their journey through this life, when they are adults for whatever reason, religious or otherwise, let them. No one should mutilate children at an age especially when they can not consent to it. RE: Uncut is better I have proof Posted by: Dr. P. Mooney on Apr 15, 2008 8:47 AM I totally, agree with you. I too, have been on both sides of this issue having my "child-hood operation" at the age of 24 or 25 yrs. old. It was done for medical reasons and had nothing to do with any of the other reasons associated with having it done. One does lose a lot of sensitivity removing the foreskin. It offers many functions from protection of the glans to lubrication of it. When the glans is continually, exposed to the elements, it loses sensitivity. I think all reasons for removing it save, medically, are not worth mutilating a functioning piece of anatomy. |

BJU International The effect of male circumcision on sexual satisfaction and function, results from a randomized trial of male circumcision for human immunodeficiency virus prevention, Rakai, UgandaGodfrey Kigozi, Stephen Watya, Chelsea B. Polis, Denis Buwembo, Valerian Kiggundu, Maria J. Wawer, David Serwadda, Fred Nalugoda, Noah Kiwanuka, Melanie C. Bacon, Victor Ssempijja, Frederick Makumbi and Ronald H. Gray OBJECTIVE
SUBJECTS AND METHODS We investigated self-reported sexual satisfaction and function among men enrolled in a randomized trial of male circumcision for human immunodeficiency virus (HIV) prevention conducted in Rakai, Uganda. In all, 4456 sexually experienced HIV-negative males aged 15–49 years were enrolled; 2210 were randomized to receive immediate circumcision (intervention arm) and 2246 to circumcision delayed for 24 months (control arm). Men were followed up at 6, 12 and 24 months, and information on sexual desire, satisfaction and erectile dysfunction was collected. These variables were compared between the study arms and over time within the study arms, using chi-square or Fisher’s exact tests. The trial registration number is NCT00425984. RESULTS
CONCLUSION
There were six measures,
and the lowest measure in anything was 98.4% Laumann et al. found a 39-46% incidence of sexual dysfunction in this age group in the US. (Maybe we should all move to Uganda - it's a sexual paradise!)
It seems their measures were too crude to measure anything. Remember, this is only a part of their study of circumcision and HIV, and they didn't want to find that circumcision harmed sexual satisfaction - as the word "reassuring" implies.
Also
Already this null finding has been reported around the world with headlines like "Circumcision Good For Sex" (Modern Ghana), "Circumcision Does Not Deter Men from Enjoying Sex" (Dr Bruno's Blog) and "Study: Circumcision Does Not Affect Sexual Satisfaction" (Fox News). Now watch these studies of adult volunteers in Uganda being used to "prove" that circumcising babies in the US is harmless! |

THE JOYS OF THE UNCIRCUMCISED PENIS
- Heidi Mark, Playboy's Miss July, 1995 |
Two studies have addressed this question, and come to opposite conclusions. Both were flawed.
"[The] women [who] preferred circumcised partners ... still found unaltered partners to evoke more vaginal fluid production, a lower vaginal discomfort rating and fewer complaints ... during intercourse than their circumcised partners." |
The O'Hara study - like these pages - is written from the point of view that intactness is normal, which may look like an anti-circumcision bias in the prevailing pro-circumcision climate.
The authors have developed their findings into a book, Sex As Nature Intended It.
Here is one woman's story.
The underlying fact is that women prefer what they are familiar with. But regardless of what a woman prefers, this should not be a consideration for circumcising a baby boy because
If a man chooses to be circumcised to please his wife, that's his decision - but read on.
Who can compare them?
It is impossible for any man to both have been circumcised in infancy and left intact; any studies must compare different men. Two groups of men have some experience of both having and not having a foreskin, though:
Back in 1964, ... I was serving a tool and die apprenticeship in a machine shop with several men that had served in the military during WWII. They shared their experiences with having been circumcised as adults. They were both circumcised when they found themselves in military hospitals during the war. One thought of it as a really good thing before it was done, (It would be a status symbol because both men came from a small coal mining town, and only the wealthy were born in hospitals, and even then, only some of them were circumcised), but he felt very much differently about it afterwards. The second man would not have wanted it done, but he was too sick to give his view on it before the operation. ... Both commented that their losses were very significant (one said he experienced a 70% loss of feeling, and the other said he had lost about 3/4 of his). You have to realize that this was only their opinions, and not the result of some measurement. Still, I find the similarities in numbers very interesting. The man that would have objected tossed in one other insight. He mentioned that masturbation was almost a complete loss. He commented that you could still do it of course, but that it had been stripped of its main pleasures. He said you could do it "to scratch an itch", but it was mostly work until he would orgasm, which he said was pretty much the same as before. The other thing that he mentioned was that now he needed either a pinup picture, or a "girly" magazine to get it to work, where he never had to use any props before. ... - John Soemer
|
As mentioned above, the effects on the nervous system of adult circumcision are different from those of infant circumcision. The circumcised boy also experiences the whole development of his sexuality with a circumcised penis - he learns to use what he's got. A man circumcised in adulthood has to relearn, and may be unable to do so.

J Urol 2002 May;167(5):2113-2116 Effect on Erectile Function, Penile Sensitivity, Sexual Activity and Satisfaction Fink KS, Carson CC, DeVELLIS RF. Robert Wood Johnson Clinical Scholars Program and Division of Urology, School of Medicine, and the Department of Health Behavior and Health Education, School of Public Health, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina. PURPOSE: Evidence concerning the effect of circumcision on sexual function is lacking. Men circumcised as adults are potentially in a unique position to comment on the effect of a prepuce on sexual intercourse. We examine sexual function outcomes in men who have experienced sexual intercourse in the uncircumcised and circumcised states. MATERIALS AND METHODS: Men 18 years old or older when circumcised were identified by billing records during a 5-year period at an academic medical center. Medical charts were reviewed for confirmation of the procedure and to identify the indication(s). These men were surveyed to assess erectile function, penile sensitivity, sexual activity and overall satisfaction. Data were analyzed using paired t tests to compare category scores before and after circumcision. RESULTS: A total of 123 men were circumcised as adults. Indications for circumcision included phimosis in 64% of cases, balanitis in 17%, condyloma in 10%, redundant foreskin in 9% and elective in 7%. The response rate was 44% among potential responders. Mean age of responders was 42 years at circumcision and 46 years at survey. Adult circumcision appears to result in worsened erectile function (p = 0.01), decreased penile sensitivity (p = 0.08), no change in sexual activity (p = 0.22) and improved satisfaction (p = 0.04). Of the men 50% reported benefits and 38% reported harm. Overall, 62% of men were satisfied with having been circumcised. [Presumably this means 12% reported no change, and they were counted among the satisfied. Considering that the 64% who were circumcised for phimosis would have expected sexual benefits, this is a remarkably poor success rate.] CONCLUSIONS: Our findings may help urologists better counsel men undergoing circumcision as adults.[Notice how circumcision is taken as a given. What these findings should do is encourage urologists to seek alternatives to circumcision.] Prospective studies are needed to better understand the relationship between circumcision and sexual function. [And before they do that, studies are needed to better understand the relationship between the foreskin and sexual function, but this is something they don't seem to want to think about.] PMID: 11956453 [PubMed - as supplied by publisher] |

adults before and after their circumcision.
Methods: The study included 123 sexually
active men that were circumcised two years
before or more. [The effect of circumcision on a man's sex life depends on why he was circumcised. If it was for a sex-related problem, an improvement is to be expected.] The mean age was 36 years (22-
64). All the men filled a questionnaire about
the quality of their sexual life and the sexual
enjoyment before and after circumcision. Also,
there were questions about partner's sexual
life improvement. The results are presented
below.

65% reported that the ejaculation latency time
increased significantly after circumcision but
only 10% of them reported that this fact
improved sexual life. 46% of men reported that
their partner's sexual life worsened after circumcision,
33% reported that their partner's
sexual life improved and 21% reported no
significant difference. [Men's reporting of women's sexual satisfaction is notoriously inaccurate.]

Intact gay men typically report that their circumcised partners are "too rough" and circumcised gay men that their intact partners are "too gentle" (untill they are taught), strongly confirming the suggestion that circumcision reduces sensitivity.
Sex manuals for gay men written by circumcised men have a hard time coping with docking: they can't deny that at least one foreskin is essential, so they downplay the whole thing, saying such things as "the pleasure is more psychological than physical" - whatever that might mean.

Work in progress
Some experiments are underway, using anaesthetics to remove sensation from the foreskin but not the glans, or the glans but not the foreskin:
"Ken McGrath, senior lecturer of pathology at Auckland University of Technology...an internationally recognised researcher on the effects of circumcision...recently simulated circumcision by anaesthetising his foreskin. He describes it as a disturbing experience, going from full sensitivity to almost none." "Foreskin's Lament" |
Other measurements of tactile sensitivity - those that Masters and Johnson and Melman et al. ought to have done - are now being made. They may further clarify the role of the foreskin in sex.
Evidence is growing that intact men's arousal is more graduated - that orgasm comes less suddenly and hence is more controllable. This can be predicted from the possession of more nerve endings - a volume control, not just a switch, for sexual feelings.

- closer than we thought? Intactivists have been inclined to suppose that male and female genitalia are differently innervated - the clitoris apparently being richly endowed with nerves compared to the glans penis - and it has been assumed that the clitoral prepuce, the woman's equivalent to a foreskin, is correspondingly nerveless. (This, in part, gives rise to the failure to communicate between opponents of FGM and of MGM.) However, one women's experience suggests that that is not the case and that a woman's "foreskin" is as sensitive as a man's: In myself, I have ... encountered what would be the inner layer of foreskin (that rests against the glans). If a woman's clitoral hood is properly pulled back, a very distinct line of demarcation, separating the inner foreskin from the outer non-sensitive skin, is quite visible. Stimulation of this "inner foreskin" gives me greater pleasure than just direct glans stimulation. I have read that without the foreskin, men do not have a warning system to tell them when orgasm is imminent. I believe that women have the same reaction. When I can stimulate the "inner foreskin" of my clitoral hood, the sensations are much different, more intense, than if I do not stimulate it. And when I do not, I, as a woman, also get the "orgasm sneaking up" problem. I think this may well be because of a lack of triggers, much like a circumcised man. Also, the pliability of the skin allows for more variation in masturbation technique, like an uncut man also gets to employ. I can cover or uncover at my will, when I feel the need; this liberty that I take for granted has been denied millions of men. - Private communication If this is true, it is obscured by the (generally agreed) fact that women's sexual response is more "global" and less centred on the genitalia than men's,

Offsite: an intact Briton with a US wife has written a page for women about how to please an intact man. He generalises from himself, is a bit shaky on his anatomy, and presents a rather alarming metallic analogy, but has a detailed chart of what gives pleasure.

In January 2001, PhD student Tina Kimmel tried to find out just what the experiments were that have proved so influential in maintaining the claim that "circumcision has no effect on sexuality". William H. Masters, 85, was in a nursing home in Arizona with Parkinson's disease and had no memory of the experiments. He died a few weeks later. Collaborator Robert Kolodny said that he never once heard Masters or Johnson refer to this study, but thought Masters might have done it in collaboration with his physiologist at the time, Dr. William Slater. Slater died years ago. Kolodny says most of the research notes from that period have been discarded, because of the rising costs of storage. He guessed that "light tactile discrimination" meant single-point threshold sensitivity, although he had no idea what "exteroceptive discrimination" meant. Ms Kimmel could not reach Virginia Johnson in St. Louis, but everyone she spoke to thought Johnson was most probably not involved in the study at all. |
