Correspondent: BRITISH MEDICAL JOURNAL June 13, 2000 Sir: I wish to raise questions in regard to an article by Robert Szabo and Roger V Short entitled 'How does male circumcision protect against HIV infection?' published in the June 10th issue.1 The authors support some of their assertions with selective referencing. For example, when they state that 'circumcision also protects against other sexually transmitted infections, such as syphilis and gonorrhoea', they are ignoring a substantial body of evidence to the contrary. Laumann et al., working at the University of Chicago, concluded on the basis of a nationally representative probability sample that 'circumcision provides no discernible prophylactic benefit and may in fact increase the likelihood of STD contraction'.2 Similarly, the authors have disregarded studies that found circumcision has an appreciable morbidity,3,4,5 and they have taken no account of a study that found a higher prevalence of HIV infection in a circumcised population.6 The result is that news media around the world have lent undue credence to questionable claims. The Globe and Mail, for instance, a daily newspaper published in Toronto and distributed across Canada, stated flatly on June 9th not only that circumcision affords protection against AIDS, but also that circumcised men contract sexually transmitted diseases at a 'markedly lower' rate than men who have not been circumcised.7 My questions are as follows:
I would appreciate a response at your earliest convenience. I look forward to your reply. References:
Sincerely,
30 June 2000 Dear Mr H arrison Thank you for your letter of 13 June raising questions about the article by Szabo and Short in our issue of 10 June. Firstly may I suggest that since you clearly disagree with the article that you send us a response to our website. I have enclosed instructions on how to do this and all letters posted on our website then become candidates for consideration for printing in the paper BMJ in our correspondence columns. To answer some of the questions you raised, the article was peer reviewed. It wasn't a systematic review (and didn't claim to be) so it's probably inevitable that it was selective in its use of evidence; it was after all arguing a case. The press release is available on our website (go to 10 June issue and click on press releases at the end of the list of contents). I'm afraid I don't know what the editorial board thinks of circumcision; it's not a question that we've asked them, and it's not a question on which we have an editorial "view". We have however published a fair amount on circumcision, both male and female, and much of it has been very critical of the practice. Again if you go to our website (bmj.com) and perform a search using the word "circumcision" you will find 87 articles that we have published on the issue since 1994. Yours sincerely,
