Men, er XY genotypes, are built with different physical body structures that provide a mechanical advantage in some arenas. Its well more than hormones.
But it is by nature an unequal contest and always has been.
It’s sad this has entered the equation.
I’m actually all for adding a 3rd division in competition. Give these folks an entirely different category to compete in. Put the gender-changed in with the XXY and XO groups. I mean they already heavily regulate and discriminate against XXY athletes and have for years. Allow them to compete against others in their category. We already do it for women so there’s precedent.
