A large proportion of HIV infections among men who have sex with men occur within primary partnerships, however, there is a lack of research focused on serodiscordant male couples. We used baseline data collected as part of Project Stronger Together—a randomized controlled trial to improve treatment outcomes among 155 serodiscordant male couples. We described engagement in HIV care/prevention using the HIV treatment cascade and PrEP care continuum. Among partners living with HIV, 86.5% were linked to care, 77.4% retained in care, 81.3% prescribed ART, 60.7% adherent, and 67.7%virally suppressed. Among HIV-negative partners, 62.6% were willing to take PrEP, 48.4% had ever taken PrEP, and 26.5% were adherent to PrEP. Black partners living with HIV had lower odds of being virally suppressed compared to White partners. Our findings provide evidence to suggest designing programs to address the racial disparities in viral suppression, addressing barriers to HIV prevention/treatment, and improving PrEP education.
