Testosterone level: Semenya receives the worst news after court ruling, Kenya’s Nyairera also affected

Kenyan’s Nyairera faces same fate as Semenya

A Swiss court ruling that blocks South African Caster Semenya from defending her world 800m title in Doha in September creates much-needed “parity and clarity” in athletics, the sport’s governing body said.

A judge at the Swiss Federal Tribunal on Monday revoked a temporary suspension on the IAAF’s controversial testosterone-curbing rules, meaning two-time Olympic champion Semenya can no longer compete in events between the 400m and mile, as she did in June and July.
