Reproductive behavior in HIV-discordant heterosexual couples: implications for counseling.

The development of effective behavioral interventions is critical to controlling the HIV epidemic. Although heterosexual transmission accounts for a growing proportion of new infections in the United States, little is known about factors that influence sexual behavior in HIV-discordant heterosexual couples. The objective of this study was to examine the reproductive behaviors of HIV-discordant heterosexual couples. Data were obtained on 71 discordant couples enrolled in a study of HIV heterosexual transmission. Results showed that women in such couples have pregnancy rates similar to those of women of reproductive age in the general population. One seroconversion occurred as a result of pregnancy attempt. These results suggest the need for educational efforts directed at HIV-discordant heterosexual couples.
