Since the earliest years of the AIDS epidemic, the issue of whether HIV can be transmitted through oral sex has been a subject of controversy.

In recent years, research has shown that adult male circumcision provides significant protection against HIV acquisition among heterosexual men in high-prevalence areas. A South African study reported in 2005 showed that elective circumcision reduced men's HIV infection rate by 61%. In late 2006, the National Institutes of Health halted 2 circumcision trials in Kenya and Uganda after interim analyses found that the procedure was associated with fewer new infections; final data from the studies showed that circumcision reduced the risk of HIV infection by 50%-60%.
