Title IX, whether you agree with everything in it or not, only applies to women/girls. Girls can play football, baseball, and wrestle. Boys can't play girls only sports, in the 1st 20 years of Title IX girls participation in sports went from 300,000 in high school to 2.78 million.

And I don't think there is a problem to be solved. Girls have a right to wrestle, boys/schools have a right to not wrestle girls.
