But enough with Morris, let's cut to the meat and potatoes and take a look at the abstract. The article is being published on the Journal of Sexual Medicine (how he gets publishers is something we can't really understand).
And what is this "new" research, one would ask? Well, it's nothing but a recycle of the same old papers. In his own words, "A systematic review of published articles retrieved using keyword searches of the PubMed, EMBASE, and Cochrane databases was performed."
From this, 2,675 publications are identified (several of them authored by Morris himself, no doubt), and they are "rated" on their quality level, to conclude that "The highest-quality studies suggest that medical male circumcision has no adverse effect on sexual function, sensitivity, sexual sensation, or satisfaction.". The problem is, what is the criteria for this rating? Which were the "low quality" studies and what did they reveal?
But, at this point we are not even really discussing the meat and potatoes of the subject, are we? Because, how can we evaluate sexual function, sensitivity, sensation and satisfaction, if we don't start by defining what those are and how to measure them? Guess what, Morris didn't.
For being a biologist, Morris willingly overlooks the question of what is sexual function, and skips the topic by going to statistics. Do you see anything wrong there?
Histological studies such as those by John R. Taylor (published in the British Journal of Urology) are evidently ignored, and most likely Sorrells' "Fine-touch pressure thresholds in the adult penis" (also published in BJU) is most likely rated with low quality, given that Morris (and his friend Jake Waskett, a computer programmer) took it upon himself to criticize that paper by distorting, eliminating and reprocessing the data, as pointed out by Hugh Young. In fact in the Daily Telegraph's article, Morris is quoted saying "There are no legitimate studies which have found a lack of sensitivity". Sorry Morris, just because you don't like the findings of Sorrells et al. doesn't mean that it's not legitimate. You can't remove 20,000 soft-touch receptors from an organ and claim that there is no difference in sensitivity.
Circumcision promoters prefer to ignore Sorrells study while paying attention to Payne et al's "Sensation and sexual arousal in circumcised and uncircumcised men" which was based on a similar methodology with a fatal flaw: Payne didn't take sensitivity measures for the foreskin, only for the glans, thus ignoring the main difference between the circumcised and the uncircumcised penis in what can only be called "researcher's bias" or "researcher's prejudice".
Anyway, the question of what constitutes sexual function is not even asked by Morris. Of course that would have to get him to explain about frenulum, ridged band, gliding function (described by Lakshman in the Indian Journal of Surgery in 1980), etc, things that he really doesn't care to talk about... because he doesn't have them.
So let's be clear here.
If sexual function means simply being able to sustain an erection and ejaculate, then, in most cases there would be no difference... except perhaps at an older age (40, 50...) as keratinization of the glans progresses.
But if sexual function means that the penis works as it was intended to work:
- The foreskin glides over the glans and allows the ridged band and the ridge of the corona to stimulate each other,
- Pre-ejaculate collects in the subpreputial space for additional lubrication instead of falling down on a useless liquid thread,
- The intact frenulum and ridged band perceive a lot of sensation and produce tingling sensations and help control the orgasmic threshold,
Then there is no doubt that removing the foreskin changes the function.
Some of the "high quality" studies would have been, no doubt, those by Kigozi et al, in Uganda (including circumcision promoter Ronald Gray) where the men that volunteered for circumcision as part of the "randomized trial" for HIV prevention, were followed up at 6, 12 and 24 months. Participants reported on "sexual satisfaction and function". Of course at 24 months, keratinization wouldn't have been enough to represent a good difference (some men circumcised during the neonatal stage report the effects of keratinization when they are past their 40 or 50 years - but I'm sure Morris would dismiss them as case-studies in the best case, or as being brainwashed by anticircumcision literature on the internet at worse).
But given that this is nothing but a "systematic review" of existing literature, then comes the question of what's the relevance of this paper. Why did Morris even bothered looking for all these articles and writing a new paper based on no new research whatsoever?
Circumcision promoters have suffered some backslash in the recent years. In 2011 the International Journal of Epidemiology published Morten Frisch's "Male circumcision and sexual function in men and women: a survey-based, cross-sectional study in Denmark" which concluded that "Circumcision was associated with frequent orgasm difficulties in Danish men and with a range of frequent sexual difficulties in women, notably orgasm difficulties, dyspareunia and a sense of incomplete sexual needs fulfilment." In spite of the expected anonymity of reviewers, Morris outed himself as one of the reviewers, as the one reviewer opposing the publication of Frisch's study, when he asked the members of his mailing list to write letters to the editor protesting the publication of the article. Quite unethical on his part.
In 2013 BJU published Bronselaer's "Male circumcision decreases penile sensitivity as measured in a large cohort", a study in Belgium, which concluded that "This study confirms the importance of the foreskin for penile sensitivity, overall sexual satisfaction, and penile functioning. Furthermore, this study shows that a higher percentage of circumcised men experience discomfort or pain and unusual sensations as compared with the uncircumcised population. Before circumcision without medical indication, adult men, and parents considering circumcision of their sons, should be informed of the importance of the foreskin in male sexuality". Strangely for a study that suggest negative consequences of male circumcision, Reuters covered the study so it reached several global news outlets. In some of the media, particularly in American news sites, a critique by circumcision promoter Aaron Tobian (Johns Hopkins University college of Ronald Gray) was included in an attempt to "balance" the information (or reduce the impact of the study, we could say).
And this would be the reason why circumcision promoters needed some "new" publication to "find" that circumcision "does not affect -or actually increases- sexual satisfaction", even if it means just recycling all the old articles, even the old and utterly debunked excuse of a "study" by Masters and Johnson from 1966 (here explained and refuted by Hugh Young).
So this is the issue. Awareness of the consequences of male circumcision has been growing. It was already reported in 1997-1999 by Tim Hammond. The past two years have seen two European articles denouncing the reported loss of sensitivity and sexual consequences of circumcision for European males and their partners. 2012 also saw the results of the Global Survey of Circumcision Harm. There is also growing awareness of the possibility of Non-Surgical Foreskin Restoration for men who feel harmed by their circumcision and wish to recover some of the function of their lost foreskin.
So obviously, circumcision promoters are not happy, especially when African men are not rushing to get circumcised as they expected them to. Aaron Tobian prepared the path for the AAP's new Policy Statement on Circumcision by publishing his "findings" (actually a computer simulation applying premises from African data to the United States) that healthcare cost would increase if circumcision rates continue decreasing. Of course even if this was true, this unethical paper is only putting a price tag on a valuable part of the male genitalia, and most of the public could see through it. More was needed, so Professor Morris did what he knows how to do: review old information to produce new publications, while denying everything that doesn't fit his model of the world.
Well, Professor Morris, it doesn't work that way. You can't deny the changes in function by simply refusing to discuss function. Good try though.
One thing we appreciate of Morris "study", and it would be pointing us to his coauthor, Krieger JN. Professor John Krieger from the University of Washington. We'll definitively be learning more about Krieger's work, such as his previous 2008 study on "Adult Male Circumcision: Effects on Sexual Function and Sexual Satisfaction in Kisumu, Kenya", which no doubt is one of the studies reviewed in this new publication, it's not like Morris has been known for self-referencing his own publications, what's the cost of sharing that trick with his coauthor?
One final thought is, why is it that European males report sexual difficulties related to their circumcision while African males don't? And why is it that the perception of African males would be more relevant to English speaking countries than the perception of European males?
But let's listen to Brian Morris for a moment, let his words give you an idea of his character. He would be quite amusing if he didn't think he was being serious.
