This question is loaded. Trans women are not really biologically male, depending on the time transition happened there will be varying degrees of masculinised secondary sex characteristics but things such as fat distribution, muscle mass, organ size changes etc are going to look much more “standard” female than male.

AFAB women aren’t excluded from sport if they’re unusually tall, or have PCOS, or some other hormone variation that leads to an advantage. Women with PCOS will have an advantage in sport involving strength because they have much higher levels of testosterone (some grow patchy beards ffs) but nobody makes a fuss over that.

All sport is inherently unfair, we try and set limits of degree of unfairness. There is no evidence that trans women have more advantages than all the usual variations in women we allow competition among without issue. The Olympics has allowed trans competitors since 2004, where are all the trans gold medalists? where are all the trans women winning everything? Have you seen the differences in male and female records for most sports? If trans women are meaningfully similar to men then the average trans women would just demolish many sports. This doesn’t happen, only a few people have attracted attention for success and that’s in an environment of media controversy with actively trying to seek them out.

Trans women who are using gender-affirming hormones are not “biologically male”. It takes about two years on hormones for their performance to equalise with cis women. The only advantage that remains is greater speed, due to the greater height gained from undergoing a male puberty. There are plenty of tall cis women, especially in sport, so this doesn’t really count as an unfair advantage. And, of course, trans kids who were lucky enough to get puberty blockers in time will fall in the same height range as their chosen gender.

I’m not going to pretend that it’s an easy question. It isn’t, and it’s not unreasonable for cis women athletes to be concerned. But the proportion of athletes who are trans is tiny and the proportion who are champions in their sport is even tinier. I do think that hormonal transition is a pre-requisite (because otherwise they would be “biologically male” with respect to the physical characteristics which matter in sport) but I don’t think anyone should be getting their knickers in a twist beyond that, and they should definitely not be using it as an opportunity to be cruel.

Most of the ‘discourse’ is pure transmisogyny, based on lies and fantasy demons. Most top professional athletes are biologically extraordinary, that’s why they are at the top.

I don’t have much time to hunt out sources but this is a decent thread from my bookmarks.

biologically male trans individuals

The preferred term is either “assigned male at birth”, or simply “trans woman”.
