Promundo's Program H stimulates young men to analyze traditional gender roles and norms associated with masculinity, challenging them to consider the advantages of gender equitable behaviors. The program consists of educational workshops, lifestyle campaigns, innovative approaches to attracting young men to health facilities, and a culturally sensitive impact evaluation methodology. The workshops draw on 5 training manuals which aim to support young men to question traditional gender norms: Sexuality and Reproductive Health; Fatherhood and Care-giving; From Violence to Peaceful Coexistence; Reasons and Emotions; and Preventing and Living with HIV/AIDS. Each manual contains a theoretical introduction to each theme, a description of the group activities and a list of references for further research. Materials are available in English, Spanish, and Portuguese.
