The Kenyan and Ugandan studies were conducted by The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). The co-principal investigators of the Kenyan trial are Robert Bailey, Ph.D., M.P.H., of the University of Illinois at Chicago, and Stephen Moses, M.D., M.P.H., University of Manitoba, Canada. In addition to NIAID support, the Kenyan trial was funded by the Canadian Institutes of Health Research and included Kenyan researchers Jeckoniah Ndinya-Achola, M.B.Ch.B., and Kawango Agot, Ph.D., M.P.H. The Ugandan trial is led by Ronald Gray, M.B.B.S., M.Sc., of Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland. Additional collaborators in the Ugandan trial were David Serwadda, M.Med., M.Sc., M.P.H., Nelson Sewankambo, M.B.Ch.B., M.Med.M.Sc., Stephen Watya, M.B.Ch.B., M.Med., and Godfrey Kigozi, M.B.Ch.B., M.P.H.
In the article I referenced -- and to which I provided the link -- there is another link to this press release by the NIH which provides more information about the studies. These were carefully done, scientific studies. Here is the link to the NIH press release.
And here is a relevant quotation from the NIH press release:
“Many studies have suggested that male circumcision plays a role in protecting against HIV acquisition,” notes NIAID Director Anthony S. Fauci, M.D. “We now have confirmation—from large, carefully controlled, randomized clinical trials—showing definitively that medically performed circumcision can significantly lower the risk of adult males contracting HIV through heterosexual intercourse. While the initial benefit will be fewer HIV infections in men, ultimately adult male circumcision could lead to fewer infections in women in those areas of the world where HIV is spread primarily through heterosexual intercourse.”
"The findings from the African studies may have less impact on the epidemic in the United States for several reasons. In the United States, most men have been circumcised. Also, there is a lower prevalence of HIV. Moreover, most infections among men in the United States are in men who have sex with men, for whom the amount of benefit provided by circumcision is unknown. Nonetheless, the overall findings of the African studies are likely to be broadly relevant regardless of geographic location: a man at sexual risk who is uncircumcised is more likely than a man who is circumcised to become infected with HIV. Still, circumcision is only part of a broader HIV prevention strategy that includes limiting the number of sexual partners and using condoms during intercourse."
As explained in the highlighted passage above, NIH believes that the results of these studies has application here in the U.S., as well as in Africa.
