Recently, circumcision has been heavily promoted as a method of preventing HIV. The [[cl:World Health Organization|World Health Organization]] (WHO) has endorsed male circumcision as a form of HIV prevention, based on three recent studies conducted in Africa (Kenya, South Africa, and Uganda) which claim that male circumcision is supposed to "reduce the risk of HIV transmission by 60%."<ref>{{REFweb

Fink abandoned the circumcision/HIV controversy in 1991, and he died in 1994. He left behind an indelible legacy nonetheless; the circumcision/HIV hypothesis continues to be supported by researchers and scientists that are adopting his assertions and writing studies based upon them, and the campaign to establish a causal link between HIV infection and the presence of the foreskin continues to this day.
== Confounding Factors factors ==
=== Debunked Adad-hoc Hypotheses hypotheses ===
Various hypotheses have been suggested in regards to the mechanism whereby circumcision prevents the tarnsmission of HIV. They have all been disproven, however, and all of the "studies" attempting to establish a causal link between circumcion and HIV transmission remain unsubstantiated by a working hypothesis.
==== Hardened Skin Hypothesis ====
Perhaps the oldest hypothesis on the mechanism whereby circumcision prevents the transmission of HIV is the theory that suggests that the keratinized surface of the penis in circumcised male resists infection, while the mucosa of the glans and inner of the intact male are ports of entry, which was purported by Aaron J. Fink.

==== Langerhans Cell Hypothesis ====
Recent circumcision studies in Africa were conducted under the hypothesis that the Langerhans cells were the prime port of entry for the HIV virus. According to the hypothesis, circumcision was supposed to prevent HIV transmission by removing the Langerhans cells found in the inner mucosal lining of the foreskin.
==== Bacterial Environment Hypothesis ====
This hypothesis attempts to identify the change in bacterial environment that results in the penis as a result of circumcision, as the mechanism whereby circumcision reduces the spread of HIV transmission. A desparate ad-hoc hypothesis, the explanation is rather farfetched. The argument is that the change in bacterial environment after circumcision makes it difficult for bacteria that cause diseases to live; there are less chances for penile inflamation, a condition that facilitates the transmission of viruses. The chances for penile inflamation are reduced, thereby reducing the chances of sexually transmitted viruses, such as HIV.<ref>{{REFjournal
| last=Price
Presenting this hypothesis presents a two-fold problem. First, it presents an irrelevant conclusion; the randomized control trials were measuring frequency in HIV transmission, not for frequency in penile bacterial inflamation, and whether said inflamation facilitated sexually transmitted HIV. And secondly, circumcision advocates give themselves the new burden of proving the newly introduced hypothesis, that change in bacterial infection does indeed result in a significant reduction of HIV transmission. A new study is needed to measure HIV transmission in men who have been circumcised, uncircumcised men with constant penile inflamations, and uncircumcised men who don't suffer constant penile inflamation. Unless the randomized controlled studies were limited to only uncircumcised men who suffered constant penile inflamation.
=== Real World Data world data ===
==== Countries in Africa ====
According to demographic health studies performed in other countries in Africa, HIV transmission was prevalent in circumcised men in at least 6 different countries:
===== Cameroon =====
In Cameroon, where 91% of the male population is circumcised, the ratio of circumcised men vs. intact men who contracted HIV was 4.1 vs. 1.1.<ref>{{REFbook

===== Lesotho =====
In Lesotho, the ratio is 22.8 vs 15.2 (23% circumcised).
''"The relationship between male circumcision and HIV levels in Lesotho does not conform to the expected pattern of higher rates among uncircumcised men than circumcised men. The HIV rate is in fact substantially higher among circumcised men (23 percent) than among men who are not circumcised (15 percent). Moreover, the pattern of higher infection rates among circumcised men compared with uncircumcised men is virtually uniform across the various subgroups for which results are shown in thetable. This finding could be explained by the Lesotho custom to conduct male circumcision later in life, when the individuals have already been exposed to the risk of HIV infection. (Additional analysis is necessary to better understand the unexpected pattern in Table 12.9.)"''<ref>{{REFbook

==== Malaysia ====
According to Malaysian AIDS Council vice-president Datuk Zaman Khan, more than 70% of the 87,710 HIV/AIDS sufferers in the country are Muslims. In Malaysia, most, if not all Muslim men are circumcised, whereas circumcision is uncommon in the non-Muslim community. 60% of the Malaysian population is Muslim, which means that HIV is spreading in the community where most men are circumcised at an even faster rate, than in the community where most men are intact.<ref>http://www.mmail.com.my/content/39272-72-percent-aidshiv-sufferers-malaysia-are-muslims-says-council</ref>
==== The Philippines ====
In the 2010 Global AIDS report released by UNAIDS in late November, the Philippines was one of seven nations in the world which reported over 25 percent in new HIV infections between 2001 and 2009, whereas other countries have either stabilized or shown significant declines in the rate of new infections. Among all countries in Asia, only the Philippines and Bangladesh are reporting increases in HIV cases, with others either stable or decreasing. <ref>http://globalnation.inquirer.net/news/breakingnews/view/20110102-312124/Philippines-HIVAIDS-problem-worries-UN</ref>
==== Israel ====
Despite circumcision being near-universal, HIV is an increasing problem in Israel.
<ref>http://www.haaretz.com/print-edition/opinion/failing-the-aids-test-1.249088</ref>
==== The United States ====
In America, the majority of the male population is circumcised, approximately 80%, while in most countries in Europe, circumcision is uncommon. One would expect for there to be a lower transmission rates in the United States, and for HIV to be rampant in Europe; HIV transmission rates are in fact higher in the United States, where most men are circumcised, than in various countries in Europe, where most men are intact.

== Problems with promoting circumcision Promoting Circumcision as HIV prevention policy Prevention Policy ==
Circumcision advocates use the latest African studies and WHO's endorsement based on them as proof "beyond reasonable doubt" that circumcision "reduces the risk of HIV." However, there are problems with the WHO's indorsment, as the studies on which it is based on suffer various flaws and confounding factors that bring their credibility in to question, many of which will be discussed in this article.
Even if the recent trials were accurate, circumcision would only reduce the relative risk of acquiring HIV between circumcised and uncircumcised men by 60% over a period of about one year. Circumcision is outperformed by condoms, which have an absolute reduction risk of acquiring HIV that's over 95% (closer to 100% when used properly). Even if a man is circumcised, he would still need to use condoms, and even the authors of the latest studies cannot stress this enough.
== Increased risk Risk to women Women ==
A recent prospective study<ref>Turner AN, Morrison CS, Padian NS, et al. Men’s circumcision status and women’s risk of HIV acquisition in Zimbabwe and Uganda. AIDS 2007;21:1779–89.</ref> showed that male circumcision offered no protection to women, and an RCCT<ref>Wawer MJ, Makumbi F, Kigozi G, et al. Circumcision in HIV-infected men and its effect on HIV transmission to female partners in Rakai, Uganda: a randomised controlled trial. Lancet 2009;374:229 –37.</ref> found that
male circumcision actually increased the risk to women. Women also are placed at greater risk from unsafe sex practices when they, or their circumcised male partners, wrongly believe that with circumcision they are immune to HIV and therefore they choose not to use condoms.<ref>Nyakairu F.
