Many contemporary scholars have described the gendered dimensions of DOHaD research and their consequences, particularly for women and mothers. In this chapter, we further these discussions by highlighting the need for a critical gendered analysis of DOHaD. This approach requires attending to both gender and racism as relations of power that are mutually constituted and shape the practices and unequal impacts of DOHaD. Examining DOHaD through a feminist and critical race lens, we provide an overview of feminist science studies of gender and DOHaD, introduce the intersections of biopolitics, medicalisation, and the politics of reproduction, and discuss the impacts of DOHaD studies that provide little attention to racism. Our analysis draws attention to how gender and racism unequally survey and manage the living conditions and behaviours of certain bodies, highlights the disparate impacts of DOHaD research, and reflects the need for what we call critical gender analyses of DOHaD and other postgenomic sciences. We conclude by considering the effects of DOHaD research on Black, Brown, and Indigenous people and the need for ongoing attention to the impacts of gender and racism in DOHaD science today.
