Olympic 800 meters champion Caster Semenya is heading to the Court of Arbitration for Sport today to challenge proposed rules that would force her to lower her testosterone levels. The South African government has said the rules proposed by track and field's governing body, the International Association of Athletics Federations (IAAF), specifically target Semenya and has called them a "gross violation" of her human rights. The controversial rules would force so-called "hyperandrogenic" athletes or those with "differences of sexual development" (DSD) to take drugs to lower testosterone levels below a prescribed amount if they wish to compete.
