It's in fact possible to develop a female body with XY chromosomes:

Thank you. But the Y test still seems sufficient. Every criterion will have false positives and negatives. With the Y test the false negative (you present as a woman but have a Y chromosome) is rare and the vast majority of cases are handled well. If you have this condition you must compete against men (given the Y chromosome test rule) or not compete. If you’re dying to be in the Olympics as a woman but have the Y chromosome, you’re just out of luck. Not everyone can be a concert pianist either. No rule makes things wonderful for 100% of humans. The Y test gets very close.

		But that's a contradiction, no? We're saving women from other women and barring trans people also (ones we consider men) because of a perceived risk that I don't see evidence for (i.e. people choosing to compete as women on a malicious basis or with an 'innate advantage' that makes it dangerous - we've had a long time of running these sports without this sort of regulation, and it seems to be a political choice more than a reaction to evidence that women are being outcompeted by trans people). This is also assuming that having a y chromosome makes it fair for people with a y chromosome to compete against one another, but if you compare people's physiology these people who present as women often have low/no testosterone. Separating on the line of testosterone picks up a lot of female athletes (especially at the olympic level) that are not trans, and overall I just see this hurting women without evidence that it's actually a response to harm. In any case, trans people and gender non conforming women become the victims of this in the public sphere. It just seems very misguided.

There will always be outliers.

High level sports consists entirely of outliers. That’s kind of the point of the olympics. This newest rule is nothing more than a misogynist rule to turn the women’s division into the “no more than statistically average” division.

		Almost every gold medal winner in the past games would not have been affected by this new rule, so that's a biiit hyperbolic. Those athletes are still far outside the normal performance of women (or men, for that matter).
