The Centers for Disease Control and Prevention (CDC, Atlanta, Georgia, USA) has recently published a report entitled "CDC Report on Male Circumcision for HIV Prevention". You can read a copy here.

Regular readers of information relating to male circumcision will be well acquainted with the writings of Professor Brian J. Morris, one of the world’s leading academics in the field of research into the health benefits of male circumcision. A new edition of his work “CIRCUMCISION: An Evidence-Based Appraisal” is now online at http://www.circinfo.net. Over 1,000 references are cited, making this a must-see website for anyone taking a serious interest in the subject. Additionally, the whole presentation has been revamped to a more modern style. There is plenty there to interest the lay reader too.

Various members of the CIRCLIST Google Group (maybe others also) have received a fraudulent email purporting to come from Dr Tasron bin Surat of Sunathrone Technologies and requesting a loan of money. This email is from "Sunathrone BM Technologies Sdn. Bhd. <sunathrone@gmail.com>", is addressed to "unknown recipients" and entitled "Urgent Request".

We have spoken directly to Dr Tasron and learn that his email account has been hacked. This message is a forgery. DO NOT RESPOND TO IT.

The Daily Nation/allAfrica.com reports that 90,000 men have been circumcised since the government launched the national voluntary male circumcision drive in November 2008. “Kenya is one of 14 sub-Saharan countries that have expanded Voluntary Medical Male Circumcision programmes since ground-breaking randomised controlled trials conducted in Kisumu [Kenya], South Africa, and Uganda revealed that the procedure reduced men’s chances of HIV infection by 60 percent”, the news service reports.

A paper due to appear in the next printed edition of the medical publication AIDS is causing a bit of a stir. The researchers, based at the University of Chicago, claim to have shown that the inner and outer foreskins of adult males are equally keratinised before circumcision. That’s counter-intuitive, because the inner foreskin is mucosal tissue whilst the outer foreskin is not. The methodology of the study is already coming in for criticism both within Chicago University and also at Johns Hopkins. If the new research findings are upheld, it will force a re-think of the existing hypothesis concerning HIV transmission. Hence the intense academic interest.

On 23.Dec the Malaysian clamp manufacturer Sunathrone announced the launch of a page on Facebook. Between Christmas and the New Year the page vanished. It has now been re-established here:

Sometime between 13:45 and 18:15 UTC Wednesday the CIRCLIST Google Group went offline. Effective 04:00 UTC Thursday it reappeared. As yet, no explanation. [Update 23.Dec.09:] Since the outage, some members have not been receiving mail as normal. Please check your spam filter; Yahoo (for example) has, since the outage, been classifying the Daily Digests of the group’s correspondence as spam.

CIRCLIST understands that an independently assessed clinical trial of the Sunathrone Clamp commences in Kuala Lumpur, Malaysia, tomorrow. It’s the peak season for circumcision in SE Asia, on account of the timing of the long school holidays. Results should become available sometime in 2010; the study aims to compare this clamp with freehand circumcision in terms of training requirements, resource requirements and outcome.

[Update 18.Dec.09: 70 boys are involved in the trial, all of whom have now been circumcised. The outcomes will be independently assessed 7 and 60 days after surgery.]

Further analysis of the data from the Rakai study (reported here 25.October.2009, see below) shows that the observed reduction in HIV transmission rates does indeed result directly from circumcision and not from variations in the rate of HSV-2 infection (HSV-2 being the virus that causes genital herpes).

Apologies to anyone inconvenienced by our absence during Friday 20^th. This wasn’t either our fault or that of our Website Hosting service; the problem was further upstream and way beyond our control.

A study of 10421 boys under 18 years of age, conducted during 2008 in the municipality of Chongqing and just published in english, reveals zero circumcisions before the age of 2 years but 17.28% circumcised in the 11 to 18 year age group. More detail on our page about China and Chinese Culture.

A while back there was great excitement about a vaccine trial that claimed around 31% efficacy. Some scepticism was expressed at the time, but now the doubts have really set in. More here:

CIRCLIST says: "Circumcision is the best form of prophylaxis that cannot be forgotten in the heat of a passionate moment".

Dr. Helen Weiss, a staunch supporter of male circumcision, has just published another gem:

Male circumcision and risk of HIV infection in women: a systematic review and meta-analysis.
Weiss HA, Hankins CA, Dickson K.

Department of Epidemiology and Population Health, London School of Hygiene and Tropical Medicine, London, UK.

Male circumcision provides long-term indirect protection to women by reducing the risk of heterosexual men becoming infected with HIV. In this Review, we summarise the evidence for a direct effect of male circumcision on the risk of women becoming infected with HIV. We identified 19 epidemiological analyses, from 11 study populations, of the association of male circumcision and HIV risk in women. A random-effects meta-analysis of data from the one randomised controlled trial and six longitudinal analyses showed little evidence that male circumcision directly reduces risk of HIV in women (summary relative risk 0.80, 95% CI 0.53-1.36). Definitive data would come from a further randomised controlled trial of circumcision among men infected with HIV in serodiscordant heterosexual relationships, but this would involve enrolling about 10 000 couples and is likely to be logistically unfeasible. As circumcision services for HIV prevention are scaled-up in high HIV prevalence settings, rapid integration with existing prevention strategies would maximise benefits for both men and women. Rigorous monitoring is essential to ensure that any adverse effects on women are detected and minimised.

Not only is there a link between HIV infection risk and circumcision status, but also it has now been demonstrated that there is a link between the surface area of foreskin and the risk of becoming infected. Furthermore, the prophylactic effect of 'high' styles of circumcision are thrown into some doubt too. CIRCLIST members have been saying this for years - at least since December 2002.

Investigators from the Rakai circumcision study hypothesised that the size of an individual’s foreskin may be associated with an increased risk of HIV infection, due to the larger surface area containing cells vulnerable to HIV infection. [This refers to Langerhans Cells - Ed.]

After adjustment for possible confounding factors, the investigators found that individuals with a foreskin area above 45.6 cm² had a significantly increased risk of becoming infected with HIV compared to men with the smallest foreskin surface area - under 26.3 cm² (adjusted risk ratio, 2.37, 95% CI: 1.05 to 5.31, p = 0.04).

The researchers conclude, "a larger foreskin area was associated with an increased risk of HIV acquisition", a finding which they suggest has implications for circumcision providers who "should avoid leaving excess residual foreskin tissue after circumcision".

"The models predicted that, using a 10-y time horizon, one new HIV infection would be averted for every five to 15 men newly circumcised. For the most successful interventions, where almost all men are circumcised, HIV incidence could be reduced by approximately 30% to 50% over the same period..."

New figures concerning the proportion of the world’s population who are Muslim cause us to revise previous estimates of the worldwide male circumcision rate. Ten years ago, the inventors of the SmartKlamp produced a video giving a figure of 1 in 6, which is a little under 17%. This now looks like a major under-estimate.

Earlier this month a body called the Pew Forum published a carefully researched report suggesting that 23% of the world’s population are now Muslim. It being a reasonable presumption that by the time of their puberty all Muslim males are circumcised, it must follow that globally at least 23% of adult males are circumcised. But how many more besides, in a world population estimated to be 6.8 billion?

Well, the Jews for a start. And an estimated 70% of males in North America. Some overlap occurs there with the Muslim and Jewish count, so an allowance must be made to avoid double-counting. In the rest of the world, at least 2% must be added for medically-necessary circumcisions and about 24 million in respect of Coptic Orthodox Christian circumcisions globally. Not forgetting countries such as South Korea, where male circumcision takes place without religious motivations.

Then there is the great unknown, Communist China. Recent reports reaching the CIRCLIST newsdesk suggest that routine infant circumcision is now the norm in maternity units, introduced as part of the state’s long-term attempts to limit the spread of HIV/AIDS. The proportion of institutional births in China now exceeds 80% (Sufang, 2007) but it will take nearly two decades for these infants to appear in the statistics for circumcised adults.

Taking all these matters into account, the proportion of adult males who are circumcised now must be no less than one in three, double SmartKlamp’s estimate made ten years ago. If the reports from China are true, then the figure can only be heading upwards.
