It's rather curious that even the experts are confused about the implications of the three African studies being used to build a case for male circumcision. The San Francisco Bay Times recently published an "analysis" piece by Stephen J. Fallon, Ph.d. Let's look at where he goes wrong.
Fallon states that New York City's health department is considering promoting male circumcision and even paying for them. This, of course, is incorrect as this blog has pointed out. As Dr. Thomas Friedan wrote in a letter to the New York Times on April 9, 2007, "The New York City Health Department has not planned, developed or
announced a campaign to encourage at-risk men to get circumcised."
Fallon talks about Langerhans cells as if they are the vehicle for infection. He states, "HIV thwarts [the immunological function of Langerhans cells] ... by riding in through [these] cells, and invading the
main machinery of the immune system." Yet, he fails to acknowledge, perhaps because he doesn't know of, a study that suggested Langerhans cells could provide a barrier to infection through strengthening their response and production of langerin. See the study. Moreover, the theory he advances is a theory without evidence. To date, there has never been a study determining the mechanism that circumcision allegedly short-circuits to reduce risk.
Fallon criticizes a study that seemed to show circumcised men at higher risk for HIV infection without acknowledging that the African studies suffered from similar weaknesses and limitations in their translation to the American context. He claims different risk trends explain the results when exactly the same issue is presented in the promotion of circumcision in the American context for HIV prevention. HIV infection is almost exclusively centered in intravenous drug users and male-on-male sex populations. Not one of the African studies touched on these transmission methods. And I'm sorry, but Israel is nearly universally circumcised. So if that was the comparison country, then I don't know what he's talking about. And clearly, he doesn't either.
Next, Fallon states that, "A newer, more
rational study in the journal Emerging Themes in Epidemiology proves
that circumcision directly reduces HIV risk." Epidemiology studies prove nothing. They show apparent outcomes in real world settings. Wikipedia, as good a source as any for definitions, states, "Epidemiology is the study of factors affecting the health and illness of populations, and serves as the foundation and logic of interventions made in the interest of public health and preventive medicine." He probably means the study he speaks of points (correctly or incorrectly as the case may be) to circumcision as a valid public health measure, but fails to mention the highly circumscribed settings for its use.
Fallon makes the jaw dropping oxymoronic statement that, " The three major [incomplete] circumcision studies
discussed here only looked at heterosexual males. Gay men would get
the same 48 to 60 percent protection from HIV that circumcision offers,
but only when they top." Ok. Did you get that? He says the studies only dealt with heterosexual intercourse, but then says gay men would get the same protection. This is a Ph.d. talking. Fallon has no credibility left by this time in his article for the alert reader. There is no evidence, and the WHO and UNAIDS have also stated as much, that circumcision has any benefit for gay men who have anal intercourse with other gay men. Fallon either knows this and is not telling you or he doesn't know, in which case he is even less to be trusted.
The only bottom line message Fallon manages to get right is that, "HIV doesn’t care if
you’re 'mostly top,' or built like a top (whatever that means), or were
exclusively the top in your last relationship. Only your next
unprotected sex matters." And a responsible HIV/AIDS educator would add you must use condoms everytime whether you are circumcised or not.
