Evaluating the risk of HIV transmission through unprotected orogential sex.
 Romero J et al. .
  Over 19,000 instances of unprotected oral sex did not lead to a single case of HIV transmission amongst a cohort of 135 HIV-negative Spanish heterosexuals in a sexual relationship with a person with HIV. A research team at the sexually transmitted diseases and HIV testing clinic in Madrid monitored a cohort of HIV-negative heterosexuals in a “steady” sexual relationship with a person with HIV. Both members of the couple were monitored at the clinic every six months and the HIV-negative partner was tested for HIV. Both members of the couple were asked to complete a structured questionnaire about their sexual practices and other possible exposures to HIV. The questionnaire explicitly asked people to specify each type of sexual practice since their last clinic visit and an approximate weekly and monthly frequency of each type of sexual activity was calculated by the researchers from their answers. A distinction was made between unprotected and protected sex and people were also asked whether ejaculation occurred. In total, 135 HIV-negative people (110 women and 25 men) were recruited to the study. Of the women, 96 had performed fellatio on their HIV-positive partner, giving an estimated total of 8,965 instances of unprotected fellatio, with ejaculation occurring in the mouth on an estimated 3,060 occasions (34%). Ninety-eight HIV-positive men carried out unprotected cunnilingus on their HIV-negative partner. Amongst the 25 HIV-negative men with a positive partner, 12 had unprotected cunnilingus, with an estimated 614 total number of episodes. Twenty-four of the 25 men had passive fellatio, with a total of 1,081 instances of fellatio without a condom performed by the HIV-positive partner.
