There is very limited literature on the experiences of fathers during Obstetric prenatal care (PNC), especially hearing from fathers’ voices directly. The MGH Fatherhood Project conducted two annual surveys—data combined for analysis—of all fathers who accompanied their partners to prenatal care visits over 2-week periods at a large, tertiary-care urban hospital in Boston, MA. The anonymous, voluntary close-ended survey was offered in multiple languages and self-administered on iPads.Results: Nine hundred fifty nine fathers participated, 86% of attending fathers, possibly making the study the largest research sample of fathers in PNC. Fathers are actively and deeply engaged with the impending birth; they have substantial physical health needs (obesity, family planning and lack of primary care), and mental health needs (stress, depressive symptoms, and personal isolation). Fathers perceived they were well treated during the PNC visit, but were desirous of more reproductive, relational, and infant health information and skills, which they preferred to receive from publications, social media, or health professionals; and they were very supportive of PNC fatherhood initiatives.Discussion: The results suggest five sets of practical recommendations to create a more father-friendly environment in Obstetric care-Staff Training; Father-Friendly Clinic Environment; Explicit Affirmation of Father Inclusion; Development of Educational Materials; and Specialized Father-Focused Health Initiatives, all with the goal of improving reproductive health outcomes for families.
