The objective of this study was to evaluate a multipronged approach to promote dual contraceptive use by women within heterosexual HIV-1-serodiscordant partnerships. Nonbarrier contraceptive use increased after implementation of the intervention. Self-reported condom use remained high during follow-up, and pregnancy incidence decreased. A multipronged family planning intervention can lead to high nonbarrier contraceptive uptake and reduced pregnancy incidence among women in HIV-1-serodiscordant partnerships.
