The review updates a previous review conducted in 2010 (Lohan et al.), summarizing the available literature on young men's attitudes and decision-making in the context of addressing two questions: (1) What are adolescent men's attitudes to adolescent pregnancy? (2) What are adolescent men's attitudes and decision-making in relation to pregnancy outcomes? Using Whittemore and Knafl's process for conducting an integrative review, 38 studies published between 2010 and 2018 reporting on young men's attitudes and decision-making in relation to pregnancy and pregnancy outcomes were analysed. This review exposes gaps in the academic literature, concerning young men's experiences of unintended pregnancy and pregnancy decision making. This review argues that a greater understanding of young men's experiences when they too experience an unintended pregnancy with a partner within a relationship or beyond it is a fundamental first step in offering reproduction and sexual health counselling and services to men. As it stands, we do not yet have a significant body of literature to inform practice development.
