Sexual and Reproductive health has historically mainly been concerned with population control and restricting the behaviour of women. When men don’t share the responsibilities or benefits and burdens of sexual and reproductive health, women bear the majority of the responsibility for their own and their families’ sexual and reproductive health. This approach exacerbates gender inequalities and leads to poor health outcomes. This model includes a framework, guidance, and concrete recommendations for building male involvement in sexual and reproductive health and rights. Three intersecting approaches for engaging men to achieve this goal are used: men as clients, men as equal partners, and men as agents of change. Organizations looking to build male involvement in sexual and reproductive health and rights are provided with the tools required to envision, plan, implement, monitor, and evaluate such programmes. The model is intended to improve sexual and reproductive health outcomes for men, women, girls and boys and requires its users to view gender equality as a critical and non-negotiable element of improving sexual and reproductive health.
