So just exactly WHO does it protect?
Male circumcision is a cost-effective means to prevent the spread of HIV, a new UN report said on Wednesday.
The study, published in the journal PLoS Medicine, found that one HIV infection could be prevented for every 5 to 15 procedures performed on heterosexual men.
The report however pointed out that male circumcision may be of a little use to curb HIV transmission among men who have sex with men.
Despite studies confirming that circumcision could reduce female-to-male HIV transmission by 60 percent, the procedure does not directly protect women from the virus, the report said.
