What would solve it is the sports governing bodies getting together and deciding whether genotype is relevant. Either it isn’t and you can’t compete if you’re xy, or a shit done of research is done to figure out what confers an advantage. Personalky I think pissing about with testosterone levels and putting limits on events is ridiculous. Just decide whether xy is allowed.
I largely agree, but they have done that research. And a cheek swab to check for XY would be step one. From there you'd check whether the condition was CAIS, which would let you through, or not.
As I understand it, the cheek swabs were stopped altogether because they were excluding CAIS, and that was determined to be unfair. They should be reinstated, with extra stages of investigation. Then Mboma and Semenya are caught early, and with far less fuss.
I agree the testosterone limit is ridiculous. If you've got the male advantage, like 5-ARD, you should be out.
But then that same rule has to apply to non-DSD 46XYs too. If they can claim "transgender" to compete, so can 5-ARD 46XYs. You can't leave that inconsistent.
At the minute the 5nmol/l rule applies to both (in athletics).
