Circumcision Doesn’t Reduce Male-to-Female Transmission of HIV

In recent years, the male foreskin—a double-folded tube of skin and mucous membrane that covers the head of the penis—has taken center stage in the battle against HIV. The foreskin is rich in Langerhans cells, immune cells that are particularly easy for the virus to access. Following infection, these cells not only serve as reservoirs for replicating the virus, but also transport it to nearby lymph nodes where HIV spreads to other immune cells. Studies have shown that removal of the foreskin can reduce a man’s risk of heterosexually acquired HIV infection by 50 to 65 percent, findings that prompted large-scale circumcision campaigns in countries with high infection rates, such as sub-Saharan Africa, where heterosexual sex is primarily responsible for the HIV epidemic. Studies had also suggested that circumcision could reduce the rate of male-to-female transmission of the virus, but that turns out not to be the case.
