The CAS media statement for the ruling on her suggests that the IAAF regulations apply to “XY DSDs”, people born with variations of sex characteristics including 46 XY chromosomes. But the 2018 IAAF regulations refer to a small range of variations including (46 XX) congenital adrenal hyperplasia.
But if we need more categories where does it stop? Do we exclude the links of Michael Phelps because of his genetic advantages? Why wasn’t he forced to take drugs?
