IAAF Ruling

The IAAF’s rules relate to the eligibility of female athletes with hyperandrogenism (higher than normal levels of testosterone) to participate in international events and hold world records unless their testosterone levels are reduced through medical intervention.
Caster Semenya is headed to the Arbitration Court for Sport to challenge the IAAf ruling that would force her to take medication to lower her testosterone levels, or be unable to compete in her specialised events.
