"The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), announced an early end to two clinical trials of adult male circumcision after an interim review of the data revealed that medically performed circumcision significantly reduced a man's risk of acquiring HIV from having heterosexual intercourse.
The trial involving almost 3,000 HIV-negative men in Kisumu, in the western highlands of Kenya, showed a 53 percent reduction in contracting HIV among those who were circumcised, while a trial with about 5,000 HIV-negative men in the Rakai District of central Uganda showed that HIV acquisition fell by 48 percent in circumcised men."
