At a snip - Helmets fend off AIDS

Another layer of the male circumcision debate is peeled back after a probing report suggests a clean snip helps prevent HIV (and presumably other STD) infection. The thrust of the report is that exposing one's bishop can cut in half the chance of infection, with potential reasons including:

keratinisation of the glans when not protected by the foreskin, drying after sexual contact, reducing the life expectancy of HIV on the penis after sexual contact with an HIV-positive partner, reduction of the total surface of the skin of the penis, and reduction of target cells, which are numerous on the foreskin.

A complex debate so it's worth getting a firm grip on the issues.
