Ed: I found the evidence in the papers themselves. I doubt that many people have actually read them, just the media hype. It may turn out that circumcision does offer some protection, but that would still have to be carefully balanced against the costs and risks, including the false sense of security it may give, the disempowerment of women, and HIV transmission itself. (So far, the claims discounting those have all come from the same people who did the original studies.) Even then, circumcision of any but informed, consenting adults would still be a human rights violation.
