Athletics’ governing body—the Court of Arbitration for Sport (Cas)—has ruled to limit female runners’ testosterone levels, following a legal challenge by 800m gold medallist Caster Semenya.
Two-time Olympian and three-time world champion, Semenya has unusually high testosterone levels, a condition called hyperandrogenism.
Today’s landmark judgement could justify future exclusions, based on differences in sex development (DSD), unless concerned athletes take long-term medication or undergo invasive surgery.
Scientists critical of the ruling argue DSD are no different to genetic mutations.
However, female athletes such as Briton Lynsey Sharp—who came sixth after Semenya in the 2016 Rio Olympics—insist letting biologically-advantaged runners compete creates “two separate races.”
Should the physical abilities of “intersex” athletes be praised, as BBC reporter Megha Mohan suggests, just as “Usain Bolt’s height and Michael Phelps’ wingspan are?”
Or is testosterone suppression necessary to level the playing field?
