Ethics of Regulating Competition for Women with Hyperandrogenism.

The International Association for Athletics Federations (IAAF) has been granted 2 years to submit further evidence showing a correlation between higher levels of testosterone and a competitive advantage. This article first presents the case of Caster Semenya, which triggered the drafting by IAAF of the regulations on eligibility of female athletes to compete in the female category in 2011. Then the IAAF regulations are critically analyzed from a scientific and ethical point of view. Finally, the Court of Arbitration for Sport decision to suspend the regulations pending further evidence provided by IAAF, and what this means for the future of sports, is discussed.
