The IOC’s shift in position on trans women in elite sports is seismic, but new president Kirsty Coventry is reflecting a changed political climate

By any measure, it amounts to one of the most astonishing U-turns from a governing body in modern times. Four and a half years ago, the International Olympic Committee was lauding the appearance of the first transgender weightlifter, Laurel Hubbard, at an Olympics, and issuing a framework to sports saying that transgender women “should not be deemed to have an unfair or disproportionate competitive advantage” over biological women.

Now it has not only ripped up every last morsel of that guidance but also performed a spectacular 180 turn as well.

Over 10 tightly worded pages, the IOC now states that the female category must be protected for fairness and safety reasons, and makes it clear that SRY screening – a sex test using saliva or a cheek-swab – will be used to determine biological sex.

It is a monumental shift that means transgender women and athletes with differences in sex development (DSD), who were reported as female at birth but have internal testes and have undergone male puberty, are now banned from the female category at all future Olympics.
