First-time fathers acknowledged the role of information on their decision making and final choices.Conclusion: Findings reveal the influence of gender norms, beliefs, and social support on first-time fathers' involvement in pregnancy and childbirth. This study also highlights the urgent need to provide informational support for first-time fathers and presents insights into what hospitals can do to achieve this need.
