Men's health literacy and its bearing on health-related attitudes and behaviour are curiously absent from discussions on health literacy and men's health. This is perhaps understandable given the lack of a theoretical understanding and empirical evidence. In this article, we review and comment on the published literature addressing health literacy and men's health literacy. We define 'health literacy', note a silent discourse on gender in the international debate on health literacy and identify gaps addressing men's health literacy. We also raise issues for research priorities and the practical development and implementation of evidence-based policies and programs aimed at improving men's health.
