Thread: Transgender Weightlifter Killing it

All prejudices re. transgenders apart. The question here is: do transgenders whose muscles developed under the influence of testosterone qualify as females as soon as they are castrated and start using oestrogen hormone replacement therapy.
We all know that muscles develop differently in men and women. This pubertal muscle development is not reversed by the use of oestrogens.
So I wonder how right it is that transgenders qualify as female in sports.

And this stands apart from the question how society should deal with their new gender. E.g. whether their passports and other legal documents should be changed according to their new gender.
