I had no idea, so I hit the google before posting.I don't know if that is actually true or not, but it would make an interesting court case if one of the teams selected a female rider and she was refused by the organisers.

I doubt they'd have much of a case. If the TDF excludes women, and a court forced them to allow them to enter, then surely that means men would be able to enter any women's competition too.
