It means that we'll have multiple male winners of women's events in Tokyo. We've already had Semenya, Niyonsaba and Wambui winning gold, silver and bronze in the women's 800m. All male athletes.
Male athletes don't have to pretend to have intersex conditions any more. Progress, you see.
There will be a big rush of male competitors in women's events, because there is a possibility that this will be their only chance to compete in the women's category, given that the IOC might change their rules afterwards.
These males cannot afford to play the long game. Because there might not be a long game.
I hope that many female athletes get together, get a class action together and sue the arse out of the IOC for lost earnings.
World Championship athletics start next week. I'm not expecting many males to enter because there is much less prestige associated with it. Plus many male athletes will only have just started to reduce their testosterone in July this year, in order to make them eligible for the women's events in the Olympics next year.
And of course some male athletes have testosterone that is naturally on the low end of the male range.
They won't have to do a damn thing in order to qualify for women's events.
