No, we've never competed in professional ones. However me and my training amateur competitions, and I found the gender categories they chose for themselves to be appropriate, having sparred with them myself. I do MMA as a hobby, I'm far from professional. But as someone who does do martial arts with trans people, I would be way more concerned about competing against a trans man than a trans woman. I know there is a whole debate here around trans people in sports, HRT has a big effect and that shouldn't be discounted.
