Semenya can’t defend Olympic title unless she lowers testosterone, court rules

Olympic champ can't defend 800m title in Tokyo without taking medication or surgery

Double Olympic 800 metres champion Caster Semenya has lost her appeal to the Swiss Federal Tribunal (SFT) to set aside a 2019 Court of Arbitration (CAS) ruling that female athletes with high natural testosterone levels must take medication to reduce it.

But the South African has indicated that she may continue her battle in the European and domestic courts ahead of the Olympics in Tokyo next year, vowing to "fight for human rights".
