Objective: To synthesise qualitative study findings in order to gain an understanding of fathers’ experiences of pregnancy. Background: As the transition to fatherhood can be challenging, awareness of the factors facilitating or hindering expectant fathers’ adjustment is important. Our aim was to better understand the experiences of men during this significant life cycle phase, and to use this knowledge to advise health care professionals on how best to support men during this transition. Methods: We used Noblit and Hare’s metasynthesis approach to review and synthesise 13 qualitative studies relating to expectant fathers’ experiences of pregnancy. Results: The synthesis revealed five super-ordinate themes, which captured the emotional, psychological and physiological experiences of the expectant fathers during pregnancy: (1) Reacting to early pregnancy; (2) On the outside looking in; (3) The pregnant male; (4) A journey of acceptance; and (5) Redefining self as a father. Conclusion: Possible clinical implications and limitations of the metasynthesis approach are discussed. Relevant recommendations on how health professionals and services can be more effectively supportive of men during this period are outlined.
