Caster Semenya says IAAF used her as a human guinea pig and fears others at risk




Semenya has won the Olympic 800m title twice and the world title three times

Caster Semenya says athletics’ world governing body “used” her like “a human guinea pig” by insisting she takes medication to control her testosterone.

South Africa’s Semenya, 28, is in legal dispute with the IAAF, who have said the 800m runner must take medication or compete over a different distance.

The two-time Olympic champion says the drugs made her feel “constantly sick” and have “unknown health consequences”.

“I will not allow the IAAF to use me and my body again,” said Semenya.

Semenya spoke out as the Court of Arbitration for Sport released a 163-page document
