WHO recommendations regarding male circumcision (2007)

...Promoting male circumcision should be recognized as an additional, important strategy for the prevention of heterosexually acquired HIV infection in men....
Male circumcision does not provide complete protection against HIV infection....
The message that male circumcision is very different from female genital mutilation also needs to be emphasized....

BTW, male circumcision reduces the male's probability to get AIDS from an infected female, but most likely not vice versa
