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.
Speaking after her victory in the 800m in the Diamond League in Doha, she said: "Actions speak louder than words. When you are a great champion, you always deliver.
“It’s up to God, God has decided my life, God will end my life, God has decided my career, God will end my career. No man, or any other human, can stop me from running.
“How am I going to retire when I’m 28? I still feel young, energetic. I still have 10 years or more in athletics.
“It doesn’t matter how I’m going to do it, what matters is I’ll still be here.”
Semenya challenged the IAAF's proposal to restrict testosterone levels but lost her legal case after appealing to CAS.
Semenya, who has a condition called hyperandrogenism which means her testosterone levels are naturally elevated, was asked to take a gender test as an 18-year-old shortly before she won the 800m at the 2009 World Championships.
