“…In April 2018, World Athletics (WA; the international governing body for track-and-field) released its female eligibility policy, which limited blood testosterone levels to five nanomoles per liter (nmol/L) for women athletes with X,Y chromosomes competing in event distances between 400-meters and a mile. While arguing that the policy was necessary for protecting ‘fair and meaningful competition’ for women's sport and encouraging ‘gender-affirming’ treatment for women with undiagnosed differences of sex development (see WA, 2019a), critics highlighted the dubitability of scientific ‘evidence’ associating testosterone with performative excellence (Jordan-Young and Karkazis, 2019; Karkazis et al, 2012), restrictive definitions of femininity (Cooky and Dworkin, 2013; Pieper, 2016; Schultz, 2011), imposition of Western ideals (Henne and Pape, 2018; Karkazis and Jordan-Young, 2018; Magubane, 2014), and scientification of gender/sex (Karkazis and Jordan-Young, 2018; Pape, 2019; Wells, 2020). Despite challenges from Caster Semenya and Athletics South Africa (ASA), in May 2019, the Court of Arbitration for Sport (CAS)—sport's highest ethical court—ruled that the policy was discriminatory, but of “necessary, reasonable and proportionate means” (CAS, 2019: 160).…”
