Olympian Caster Semenya had a two-word response to the Court of Arbitration for Sports ruling she would have to take hormone suppressants to keep competing in events: Hell no.

Semenya pushed back against a ruling from the CAS that determined her body produces too much testosterone to compete with women. In its ruling, the CAS admitted testosterone regulation are discriminatory, but necessary to keep integrity in womens running.

As a result, the CAS ruled Semenya would have to take hormone suppressants if she wanted to continue competing in events ranging from 400m to a mile. Semenya has dominated the 800-meter event, winning gold medals at the Olympics in 2012 and 2016. Shes also won the gold in the 800-meter event at the IAAF World Championships three times. Due to the CAS ruling, Semenya would not be able to compete in the 800-meter event anymore unless she took hormone suppressants.

The 28-year-old Semenya is allowed to run longer events, but she has no interest in doing that, according to Pippa Field of The Telegraph.

In its ruling, the CAS admitted there could be difficulties involved in regulating testosterone levels. It also admitted theres no concrete evidence elevated testosterone levels would provide an advantage to women in the 1500-meter events.
