Eight out of 10 american women of childbearing age have taken the Pill to prevent pregnancy, yet most are unaware that the oral contraceptive has another use. In a somewhat higher dose, it can serve as a "morning after" drug to avoid pregnancy after unprotected...
Scientists, by focusing only on the sexual relations of gay people, tend to suggest deceptively that oral sex may be a problem faced exclusively by homosexuals [MEDICINE, June 17]. I teach biology at a large community college, and most of the questions about the safety of oral sex are from heterosexual students who have probably switched to oral sex from other forms of sexual expression for its purported safety. It is important to inform everybody, irrespective of sexual orientation, that practicing oral sex isn't the easy way to avoid HIV and AIDS. RAGUPATHY KANNAN Fort Smith, Arkansas...
...study, scientists from Boston's Dana-Farber Cancer Institute and Tulane University tried to infect 15 sedated monkeys with SIV, the simian cousin of the AIDS virus. To simulate oral sex, researchers dribbled an SIV solution onto the tongues of seven animals. Then, for comparison, they carefully placed SIV in the rectums of eight other monkeys. Much to their surprise, they found that it took less of the viral solution to infect a monkey orally than rectally--6,000 times less...
...particles found in an infected man's semen--though not in the saliva--is sufficient to be passed on through the mouth or throat. One likely route: the tonsils, which contain large numbers of the kinds of lymph cells favored by HIV and SIV. "We're not saying that oral exposure is more dangerous than anal exposure," notes Dr. Ruth Ruprecht of Dana-Farber. "What we're saying is that oral sex is not safe...
...anal sex was the principal means by which HIV spread through the homosexual community in the 1970s and '80s. More recently, however, as more and more gay men adopted "safer" sex techniques, reports began surfacing of people who had become infected with HIV even though they had engaged in oral sex only. Erring on the side of caution, the federal Centers for Disease Control and Prevention in Atlanta added unprotected oral sex to the list of unsafe sex practices several years ago. "From our standpoint, the study reinforces the evidence we've collected over the years," says Dr. Helene Gayle...
