South African mid-distance runner Caster Semenya filed an appeal May 29 against the Court of Arbitration for Sport's decision to uphold testosterone regulations for some female athletes in track and field, ESPN.com reported.
Her lawyers said she lodged an appeal with the Swiss Federal Tribunal, Switzerland's supreme court.
In May, in a two-to-one opinion, the international Court of Arbitration for Sport upheld a proposed rule by the International Association of Athletics Federation ( IAAF ) that compels women with high levels of testosterone to take suppressants in order to compete in some women's races. National Center for Lesbian Rights Legal Director Shannon Minter called the opinion "cruel, unprincipled, and riddled with internal contradictions."
Semenyawho is also a three-time world championis one of a number of female athletes with medical conditions known as differences of sex development that cause high levels of natural testosterone.
