Why did it take Seb Coe so long to see sense over transgender athletes?

World Athletics has decided to protect women’s sport by restricting it to females. From 31 March, transwomen will not be allowed to compete in elite female competitions if they have gone through male puberty. Following yesterday’s meeting of the World Athletics Council, Seb Coe – the governing body’s president – explained that the decision was ‘guided by the overarching principle which is to protect the female category’.

That decision should be welcomed by everyone, but why did it take them so long? Swimming’s world governing body came to the same conclusion last summer; world rugby got there in 2020. Athletics, meanwhile, dithered and fiddled with rules based on the level of testosterone in an athlete’s blood. Should the cut-off be set at ten nanomoles per litre, or should it be just five? Recently, two and a half was mooted. These appeared to be little more than arbitrary lines, set at a level somewhere between the typical male and the typical female.

But men and women are, of course, not defined by the hormones in their blood.
