Researchers reported at Barcelona on a study looking at the risk for heterosexual HIV-transmission to women through receptive anal sex between HIV-infected men and their monogomous female partners. They used data from the California Partners Study. The researchers reported that the risk of transmission for each individual anal contact was 10 times higher than the risk for each individual vaginal contact. These authors concluded that the results confirm their previous finding that anal intercourse is a far more efficient mode of transmission than vaginal intercourse. They say further that a significant proportion of heterosexual HIV transmission results from anal sex particularly among people who practice anal sex a lot.
