As Positive Masculinity (PM) Programmes continue to develop globally, it is important to examine their role in Sexual and Reproductive Health and Rights (SRHR) outcomes. This multi-country qualitative study was conducted using in-depth interviews (IDI) and focus group discussions (FGDs) with community members, beneficiaries and implementers of PM programmes. The findings show that PM programmes are designed using a gender lens to make boys and men more aware and conscious of harmful masculinity traits and their effect on SRHR. The beneficiaries of the interventions report imbibing positive SRHR behaviours by being sexually responsible - upholding sexual rights, taking precautions against sexually transmitted Infections (STIs) and learning proper communication with their partners. They also report acting as vanguards of positive gender norms to their families and peers. Although there are challenges in implementing PM programmes, the results of the study suggest that interventions targeting boys and men hold promise for improving boys' and men's health behaviours and promoting gender equality in poor urban settings.
