Caster Semenya has criticised the IAAF for using her as a “human guinea pig” after the Court of Arbitration for Sport (CAS) published its arbitral award following her case.

CAS ruled that the IAAF could implement a regulation that would require Semenya to take medication to lower her testosterone levels in order to compete against women in track events ranging from 400 metres to a mile.

The two-time Olympic 800m champion is awaiting the outcome of an appeal to the Federal Supreme Court of Switzerland to overturn the ruling.

Yet the release of a redacted 163-page CAS award on Tuesday saw Semenya and her legal team provide a further scathing response.

“The IAAF used me in the past as a human guinea pig to experiment with how the medication they required me to take would affect my testosterone levels,” she said in a statement.

“Even though the hormonal drugs made me feel constantly sick, the IAAF now wants to enforce even stricter thresholds with unknown health consequences.

“I will not allow the IAAF to use me and my body again. But I am concerned that other female athletes will feel compelled to let the IAAF drug them and test the effectiveness and negative health effects of different hormonal drugs. This cannot be allowed to happen.”

The statement from Semenya’s team highlighted the “extremely thin basis” of the regulations they felt were evident in the award, while criticising the IAAF’s subsequent actions.
