Three leading scientists reportedly say a report relied on by the IAAF to rule that intersex athletes must medically lower their testosterone levels is full of inaccuracies.
The IAAF’s rules relate to the eligibility of female athletes with hyperandrogenism (higher than normal levels of testosterone) to participate in international events and hold world records unless their testosterone levels are reduced through medical intervention.

Semenya will require the strength of a lioness in her fight against these decisions made in musty rooms by mostly middle-aged men.

So for the sake of sport's future, we must remain sceptical, remain inquisitive, but not lose our hope, not give in to cynicism. Sometimes having faith is more important than having doubt.

On Friday night I was lucky enough to bear witness to the electricity meter at the London Olympic Stadium explode with the buzz of the Anniversary Games. It was just fantastic for the world to focus solely on the talent...

The truth is that in tennis, and most other major sports, only a small amount of resource is invested in fighting corruption. They are simply no match for the organised crime gangs, international gambling syndicates, and greedy dishonest officials. Sports governance has become a wild west, but we need more than a lone ranger to combat it.
