Initially I thought the age 12/tanner stage puberty was a cop out by FINA but actually, having read the last couple of pages, it could be a very tactical move. So, FINA are not discriminating against transwomen per say, they are saying male puberty embodies physical characteristics that give an advantage. So the starting point is that men have a physical advantage - duh, of course we know that, and it can be easily proved by comparing world records for men and women in lots of sport - so then the discussion and legal cases would be, if they go that far, how much disadvantage reduced testosterone impacts men. team sports like rugby should have an easier case to make on the basis of safety for women, so the big focus will be on individual performance sports.
Joanna Harper's trials and research would seem to be so biased and not able to be peer tested to be worthless.
So then the question is, how do you really test that reduction. There are two options. Let transwomen compete in womens sport and see how they do - the Joanna Harper approach - and then assess the impact on women. Alternatively, the transwomen have the option to compete in their biological sex category and assess how they do on lower testosterone over, say 10+ years.
And then we are back to the key point - do you include a very few entitled transwomen and disadvantage all women, or do you have fair sport and have a level playing field for women, and make those very few TW make real life decisions of whether to delay transition while they play sport at a higher level. In the same way women defer motherhood while they compete- or try and time pregnancy with other goals and hope they can regain that elite level when they return.
Cycling currently are sitting on the wrong side of the fence- only wanting meaningful competition, not fair competition - but I am hopeful, especially if athletic change their policy following comments made by Lord Coe.
Add in the fact that TW like Lia Thomas and Emily Bridges conveniently transition when their success in their biological sex category is waning ..............
