As a blanket statement, definitely wrong. But statistics are on the side of increased muscle mass, and increased muscle mass is associated with adolescent boyhood. That's an issue that doesn't impact social performance, but it can affect athletic performance -- ergo the reason for forbidding performance-enhancing drugs in many sports. A performance-enhancing drug won't, in fact, make me into a world-class athlete, but it might improve my performance when combined with the right training (which, were I an athlete, I might be doing anyway).
We as a society haven't gotten this right yet. And it's not up to people who are mostly past high-level competitive athletics to decide. I played co-ed volleyball when I was working (company leagues). It wouldn't have mattered in the least if there had been a transgender man or woman on the team. That's reality for the vast overwhelming majority of us -- it just doesn't matter. Let's leave it to the people for whom it does matter to work out. Note that it only matters to Tucker Carlson etc. for the ratings.
