Men and boys have their own distinct health needs and vulnerabilities, and engaging men can benefit everyone—including women and girls. What should you do, and not do, when engaging men & boys in health promotion and gender equity? Developed by the USAID Interagency Gender Working Group’s Male Engagement Taskforce, this 2-page fact sheet brings together recent best practices and lessons learned for male engagement across health areas. It is intended to guide decision-making about programs, policy, media coverage, research, and funding priorities. The fact sheet is available in English, French, Portuguese, and Spanish.
