MTN-045 was a cross-sectional study that utilized questionnaires, including a Discrete-Choice Experiment (DCE) and joint decision task, to assess couples’ preferences related to dual purpose products (DPP) that could be used to prevent unintended pregnancies and HIV infection. The study enrolled 400 couples. Couple members’ preferences were evaluated with each partner separately and also with both partners together. Post-survey explanatory IDIs were conducted with a subset of couples (60 participants from 40 couples). The following DPP product forms were evaluated in this study: vaginal ring, vaginal insert, vaginal film, and oral tablets.

The study completed follow-up on November 5, 2020. Interim primary results were presented at the Research for Prevention (HIVR4P) conference held virtually on January 27-28 and February 3-4, 2021.
