I’ll be fully open, I do agree that having a transwoman compete (especially in boxing or other strength-based matches) against a ciswoman is perhaps not the most fair & sportsmanlike matchup. Being born with XY Chromosomes does give a transwoman inherently extra muscle mass and thus an unfair advantage there. The IBA does seem to agree with me on that front, for whatever it is worth.
Don’t be so sure about that. There are intersex conditions where someone has XY chromosomes and are, other than their reproductive systems, indistinguishable from cis women. (not to mention how intersex women with XY or other non-XX chromosomes don’t have to be transgender at all!)
Probably the best example of this is complete androgen insensitivity syndrome (CAIS), where the woman has XY chromosomes but her body is unresponsive to male hormones. She can even pretty much go through normal female puberty naturally. (seriously, I suggest reading the article)
So… no, being born with XY chromosomes doesn’t necessarily give you an inherent physical advantage. Especially if you’re looking at certain intersex conditions.
Also, even with actual trans women who transition, a lot depends on when they transition, did they go through male puberty, as well as how long they have been on hormone therapy. Not to mention how feminizing hormone replacement therapy reduces that ‘inherent’ extra muscle mass.
Yes, some things can’t be changed after male puberty; but muscle mass isn’t one of them.
It’s not about the XY chromosomes; it’s about the testosterone.
Oh, also, take care when it comes to claims about the athletic performance of trans women. The research is still evolving, there’s lots of claims (some contradicting each other), and different sports bodies have very different guidelines or rules — even in the same sport at times.
It’s not just about the science, after all; currently, this question is a burning political issue and controversy (a moral panic, even), and that can affect how sports bodies approach it.
After all, why would a sports body governing pool (AKA billiards) or even chess ban trans women from competing with cis women? What big “inherent unfair advantage” do we have there, even before hormone therapy (let alone on it)?? And yet, such bans have recently happened.
This is not solely a fairness issue. Please don’t fall for that sort of talk.
