The problem with this is that it's almost entirely based on prejudice and people saying things that turn out not to be true ... Caster Semenya [has] high natural testosterone
Caster Semenya has XY chromosomes and internal testes. Semenya has "high natural testosterone" as a result of having male anatomy and hormones. The specific regulation Semenya has been fighting is explicitly "limited to athletes with ’46 XY DSD’ – i.e. conditions where the affected individual has XY chromosomes."
The idea that testosterone confers physical advantages of strength/speed is not "vague biological determinism" it's one of the most basic facts of our existence. It the primary reason sex-segregated sports exist in the first place.
"To say that an XY human can’t compete in the women’s category of professional sports unless they lower their testosterone below 5 nmol/L — a figure that is still 7.5 times the value of the average woman competing at the 2011 and 2013 track and field World Championships and a figure that not a single healthy woman born with XX chromosomes, ovaries, and producing estrogen at puberty can reach — isn’t a huge human rights travesty. It’s a protection of women’s sports."
