Growing up under the influence of male genetics and hormones gives an individual a massive advantage in such a sport, that simply cannot be compensated for or against with just training or medical solutions. There's nothing that will take that edge away from such an individual because human intervention later in life can't entirely undo the course nature took when building that body.
The evidence is in the performance which falls squarely in line with male performance [0].
And to everyone thinking of a parallel with motorsports and whatnot, there is none. Those sports rely on technology developed by humans so anything is entirely reproducible and reversible. Nature on the other hand still does things that we don't understand, can't reproduce, or can't fully compensate for. We have no way to change the gender with all the associated factors so we focus on the critical and obvious ones like physical look and hormonal balance, which get a person 95% there. But when it comes to peak performance the 5% makes a difference and it's clearly an unfair one to every other participant.
