Caster Semenya has filed an appeal against the recent ruling to limit testosterone levels for female athletes.
Earlier this month, the IAAF and Court of Arbitration for Sport ruled the Olympic champion would have to take medication if she wanted to compete against other women at international level.
She has filed an appeal to the Federal Supreme Court of Switzerland regarding the regulations.
Semenya said: “I am a woman and I am a world-class athlete. The IAAF will not drug me or stop me from being who I am.”
If the rule is upheld, Semenya would not be able to defend her 800m title at the World Championships this year.
