Commentary: Methods women can use that may prevent sexually transmitted disease, including HIV

Although sexually transmitted diseases, including human immunodeficiency virus (HIV), are a major concern for women, few prevention messages are targeted specifically to women. Those that are generally stress abstaining, altering the number or selection of partners, and urging partners to use condoms. But these behaviors may be unrealistic for many women, particularly women who are at highest risk for sexually transmitted diseases, because they require significant changes in lifestyle or depend on male-controlled condom use. Recommendation of contraceptives for prevention of sexually transmitted diseases depends largely on how well specific methods perform under controlled conditions, either in the laboratory or in clinical trials. Observational studies, which better reflect day-to-day use, indicate that condoms, barriers, and spermicides, used property and consistently, can provide substantial protection against various sexually transmitted diseases. Condoms can similarly help protect against HIV, but studies of barriers and spermicides are scant and currently inconclusive. Finally, those methods that are controlled by women are consistently more effective in preventing sexually transmitted diseases. Thus, although condoms used well are still the best choice, the imperative for female-controlled methods indicates that diaphragms and spermicides should receive greater emphasis in prevention messages.
