Statewide for youth sports in Missouri, Tennessee, South Carolina, Alabama, Texas. Tennessee does allow college aged trans men to compete as men. This includes 15-16 year olds who are on testosterone. They do allow trans boys to compete if there is not a girls' team to stuff them back into, except in Tennessee where nope.

Of course, they're banning them from transitioning in these areas anyway. But all of the bans except Tennessee apply to college kids, most of whom are adults.

In Texas, high school wrestler Mack Beggs was forced to compete in the women's division. He won every single match and the state championship. He only did it to prove a point and was not able to continue his career.

The goal is, again, to force them to closet. These places are just saying the quiet part out loud.

Trans men also, almost universally, have to jump through ridiculous hoops to be allowed to compete at all. I know a trans man who had to go through a two year process to prove he was trans to be allowed to compete in equestrianism. Which is not gender segregated. But he had to prove he wasn't doping. Two. Years. In a co-ed sport in which testosterone provides no advantages whatsoever.

As a side note, World Athletics forces some intersex women to compete as men (not competitive) or take testosterone blockers. Which have some pretty gnarly side effects.

World Rugby to trans men: The second you take that first testosterone injection, you're off the women's team. But you can't compete on the men's team either until you've proved you can keep up with cis guys. So sorry!

World Boxing Council is banning in both directions.

Another thing I would point out is: Elite sport is not fair. Elite sport is never fair. To compete at the highest levels you have to have the drive, the talent, and the physical conformation for the sport you choose. Simone Biles is perfectly built to be a gymnast. Michael Phelps is perfectly built to be a swimmer.
