Man Named 'Tiffany' Is Dominating Women's Pro Volleyball in Brazil

I like the suggestion of using ability classes and ignoring gender altogether.

The problem is you take out half the countries ability to play organized sports.  How many college basketball leagues do you need to have running before you get one that a woman can make the team?  Obviously no professional sports careers or athletic scholarships will be available to any women.  

And if this goes into youth sports, there are almost no girls playing high-school sports.

Practically speaking, trans athletes need their own leagues.  The problem is there just aren't enough of them yet for that to be possible.  But this is the solution that would allow trans men to compete, and would keep trans women from having an unfair advantage.
