Men’s attitudes to reproductive decision making and their psychosocial and relational adjustment during the transition to parenthood have received limited theoretical and research attention. This chapter explores the transition to parenthood from the perspective of fathers and evaluates the extent to which psychological theories that were developed in the context of traditional views of women and femininity apply. The chapter reviews research on how fathers come to terms with the reality of pregnancy, develop a relationship with the unborn baby, and restructure their work and social networks in anticipation of becoming a parent. Challenging contexts for fatherhood, changing gender role expectations and tendencies of services to marginalise or ignore father needs are discussed.
