As I said, it wasn't a hostile question.
I'll point out again that in the 1990s the International Olympic Committee used "does not have an SRY gene" as their criterion for eligibility for the women's events. The reason they stopped wasn't that they changed their minds, but that they concluded it wasn't cost-effective.
The tests were set up as the latest and most sophisticated "definition", superseding things like karyotyping, as a guard against cheating. Earlier in the century some countries had been suspected of entering feminine-looking men for the women's events. I don't know if they caught anyone at that point, but that was the reason for the testing. They tested everyone entering for the women's events, which was serious overkill, but presumably they didn't want to stigmatise women who looked a bit butch. They did find some SRY genes, but nobody was eliminated as a result because the decision was that they had not found any deliberate cheating.
Understandably the reasons for the presence of the SRY genes they found were not published. It may be that there were CAIS or Swyer women there. It may be there were women with mosaic or chimera conditions there. It may be (and I think this may be more likely) they found some undiagnosed 5ARD athletes and decided that as they weren't deliberately cheating, and the rules about DSD conditions weren't formulated at that point, they'd let them compete rather than stir up controversy. They looked at the cost (a lot) against the number of cheats identified (none) and decided the game wasn't worth the candle.
Now that more and more athletics organisations are coming straight out and saying that nobody who has ever gone through male puberty is allowed to compete in women's events, the question of testing will surface again. A large majority of female athletes in a recent poll wanted them to reinstate this testing. They may stick to karyotype plus hormone levels, but they may well go back to the SRY gene testing.
So basing a definition of male and female on the presence or absence of an SRY gene is neither without precedent nor unscientific. It may well become standard practice again.
