This brochure highlights key resources for working with men and provides a framework for distinguishing among the varied programmes, research and tools that are available. The framework reflects different approaches to such work: men are viewed as “clients” (focusing on men's own reproductive health needs), as ”partners” (focusing on promoting men's central roles in supporting women's health), or as “agents of positive social change” (focusing on engaging men in the promotion of gender equity). The main body of the brochure provides key resources - programme reviews, evaluations, policy examples, and tools - for five important areas: family planning and contraceptive use; maternal and neonatal health and fatherhood; male identities and roles; sexually transmitted infections and HIV/AIDS prevention, diagnosis and treatment; gender-based violence; and policy.
