The document discusses a project in Nicaragua that aimed to improve maternal and child health outcomes by increasing men's involvement. Formative research was conducted to understand men's behaviors and barriers. The intervention provided father-focused counseling to increase men's knowledge of pregnancy complications, encourage joint decision-making, and support their wives. Summative research found the intervention increased men's knowledge, the number who accompanied their wives to antenatal care and health facilities, and institutional deliveries in intervention communities compared to control communities. Challenges included a longer formative research phase and contamination between control and intervention areas.
