The book explores "the Caster Semenya Case" from socio-cultural, ethical and legal perspectives. The South African athlete Caster Semynia (1991) won the 800m title at the 2009 World Championship and she was obliged to undergo gender testing and was for a time withdrawn from international competition. The book explores the ethics of how gender norms in sport, and in society more generally, are constructed through appearance, behaviour and sporting performance. It analyses the impact of standards in sports; the interrelationships between sport, culture, and the media; the link between mediacal sciences, society and gender; and includes discussion of key concepts, such as intersex, body norms and fairness.
