Previous research has suggested circumcision doesn't make a difference when anal sex is involved. The latest study, by CDC researchers, looked at nearly 4,900 men who had anal sex with an HIV-infected partner and found the infection rate, about 3.5 percent, was approximately the same whether the men were circumcised or not.

Circumcision, which has helped prevent AIDS among heterosexual men in Africa, doesn't help protect gay men from the virus, according to the largest U.S. study to look at the question.
The research, presented at a conference Tuesday, is expected to influence the government's first guidance on circumcision.
Circumcision "is not considered beneficial" in stopping the spread of HIV through gay sex, said Dr. Peter Kilmarx, of the U.S. Centers for Disease Control and Prevention.
