Semenya, who hails from South Africa, identifies as female and was judged to be female at birth, but has naturally higher levels of testosterone and XY chromosomes.

Caster Semenya was elevated for the gold medal position two years ago when Russian athlete Mariya Savinova was later disqualified for doping violations.

In June, it was announced that Semenya was free to run the 800m without having to take medication. But later, she was denied participation in her favoured 800 metres race in Morocco, following a rule change by the IAAF, athletics’ governing body.

Semenya, the 800m Olympic title winner in 2012 and 2016, was fighting IAAF’s imposed “hyperandrogenic” rules — the regulations for athletes with ‘Differences of Sexual Development’ who want to compete in the female category.

Olympic 800m champion Caster Semenya has accused the world athletics’ governing body, the IAAF, of using her as a ‘human guinea pig’.
