What's wrong with this argument?

[David Canzi]

For some sports, men have an advantage over women. Women's sports
leagues exist so women can compete with a more fairly matched set
of competitors. If transsexuals who have transitioned from male to
female retain their male advantages, it is not fair to allow them
to compete in women's sports leagues.

That's not the only reason they exist nor is it proven to even be among
the primary reasons.

The point of my argument doesn't depend on this being the main or only
reason.

Nevertheless, what are some of those other reasons?

Similar to a convent or a boy's school it separates the sexes to avoid
unwanted pregnancies. Co-ed beach volleyball isn't a very serious sport.
