South African athlete Caster Semenya has been unsuccessful by the Supreme Court in Switzerland in her legal battle against new regulations from the International Athletics Federation.

This means that the two-time Olympic champion in the 800 meters will have to take medication if she wants to compete again at her favorite distance.

However, she refuses to take testosterone inhibitors to artificially lower her naturally high levels.

World Athletics introduced a maximum testosterone level in April 2018 for athletes at distances from 400 meters to a mile (1609 meters).

Their muscle-strengthening effect would give them a disproportionate advantage over most women who don’t.

Semenya subsequently conducted various lawsuits and also appealed to the international sports tribunal CAS. However, she couldn’t get her right anywhere.

After her new defeat in the appeal case in Switzerland, her legal options seem exhausted. However, that does not mean that Semenya will be absent from the Tokyo Olympics in 2021.

She wants to start in the 200 meters in Japan.
