Sex, Gender Identity and Sport (Routledge), edited by Cathy Devine, addresses the highly contentious debate surrounding sex-based categories in competitive sport. The volume advocates that preserving these categories is essential for ensuring fair competition. In this high-quality review, Alexis Sossa concludes that the book is most valuable not as a definitive resolution to the transgender sports debate, but as a provocation regarding the politics of bodily classification. While its explicitly partisan orientation and tendency to dismiss opposing perspectives as “ideology” leave complex empirical and normative questions unresolved, its enduring contribution lies in insisting that sports politics are inextricably bound to body politics.
