The Interagency Gender Working Group’s Male Engagement Task Force (METF) is an information, advocacy, and knowledge exchange network on what it means to engage men and boys in health promotion and gender equality. The METF aims to explore why we should engage men and boys, what are the benefits, how to do it, what works and doesn’t work, and what modalities of health services can better reach and include men and boys. The diverse health areas addressed include family planning (access, delivery, uptake, utilization, FP methods), sexual and reproductive health and rights (SRHR), maternal newborn child and adolescent health (MNCAH), breastfeeding, gender-based violence (GBV), HIV/AIDS (prevention, testing, treatment, care, adherence), malaria, and tuberculosis. The METF will consider relevant efforts to understand and address these health areas across social and behavior change (including shifting social and gender norms), service delivery, research, and policy.
