Sorry correction, Worley transitioned aged 38, not 48.
Anyway:

Worley had testes and male testosterone levels (20-30 nmol/l) for ~25 years, then had testes removed so down to normal female level (0.5-1.5 nmol/l).
'Worley’s medical reports clearly showed that her body needed a certain level of testosterone for her overall health. At lower levels, she suffered a number of health problems and training for high performance sport became impossible. '
So got permission to take steroids as a TUE.
And then got another sick note saying 'not enough roids, I want to take more'
" subsequent health problems led her medical team to recommend increased synthetic testosterone. When she applied for an updated exemption, she was subjected to invasive gender verification testing above and beyond WADA’s usual requirements."
so basically this, er, woman doped with testosterone, which we are lied to by these lying liars from liar land, is not the 'male hormone', but just a generic hormone produced in 'different proportions' (whatever could those 'different proportion's be, oh lying ones?) , and 'male and female athletes in the same sport shared similar fitness levels' with 'testosterone overrated when it comes to athletic achievement.'
And then having done that decided they wanted to up the T a bit more, for 'health reasons', to levels which aren't disclosed but implicitly (because of the rules, which then restricted testosterone to 10 nmol/l) are several times the 'female' range and in fact in the 'male range.
And then the nasty transphobic biologists on the IOC got the hump, so they've had to write a book about the evilness of biology and gender verification and how terrible it is that someone who spent most of the adult life as a man could possibly still be considered 'male' for sporting purposes.
