Any person with testosterone is going to be stronger and faster than someone without testosterone. That is why they test for it before the race.
That is the current “sex” test for determining if somebody can compete in women sports.
If their testosterone is low.
But that is not what determines sex. testosterone levels can be easily manipulated and changed.
Even with low testosterone levels, men are bigger, stronger build, have more muscle mas, etc.
The only real sex test is the DNA, which is given to every individual during conception and cannot be changed!
