Work with men has demonstrated significant potential in contributing to building gender equality and improving the health of women and men. However, most work with men has tended to be local in scale and limited in scope. Being more widely effective in transforming the pervasive gender inequality that characterizes many societies globally requires significantly scaling up efforts to transform men’s behaviour. Policy processes and mechanisms are key elements in any effort to engage men and boys in achieving gender equality. Gender equity means fairness of treatment for women and men according to their respective needs, including health needs. This training module is intended to be used to build the capacity of health managers in national departments relating to public health and ministries of health and multinational agencies, including WHO, to develop evidence-informed policies and programmes intended to engage men and boys in achieving gender equality and health equity.
