Lausanne, Switzerland (AFP) – South Africa’s double Olympic 800m champion Caster Semenya cannot compete until she accepts to be treated with hormone- suppressing drugs, the Swiss supreme court confirmed on Tuesday.
The court dismissed the appeals submitted by Semenya and her athletics federation against the decision by the Court of Arbitration for Sport on eligibility regulations for differences of sexual development (DSD) athletes.
World Athletics banned Semenya and other DSD athletes from races between 400m and a mile unless they take testosterone-reducing drugs.
Semenya is classified as a woman, was raised as a woman and races as a woman.
But for World Athletics, women like Semenya, with certain masculine attributes due to DSD, are classified, biologically, as men. It is a position hotly contested by South African officials.
In the build-up to the 2009 world championships in Berlin, where an 18-year-old Semenya went on to win gold in the 800m, the South African had to undergo gender verification testing to confirm her eligibility to compete in the women’s category.
She was subsequently put on medication to reduce her testosterone levels, spending six months sidelined by World Athletics.
Semenya, born with the “46 XY” chromosome rather than the XX chromosome most females have, described the experience as like that of being treated like a “human guinea pig” and vowed never to again allow World Athletics (then known as the IAAF) to enforce medication upon her in order to compete.
