Both gender and the law are significant determinants of health and well-being. Here, we put forward evidence to unpack the relationship between gender and outcomes in health and well-being, and explore how legal determinants interact and intersect with gender norms to amplify or reduce health inequities across populations. The paper explores the similarities between legal and health systems in their response to gender—both systems portray gender neutrality but would be better described as gender-blind. We conclude with a set of recommendations (...) to address both law and gender in implementing the work of the Lancet Commission on the legal determinants of health to improve health outcomes for all, irrespective of gender.
