if a man had abnormally high testosterone such that it makes him he is either 'talented' or 'the next stage of human evolution' or some combination of the two.
If this happens in a woman she is a freak and forced by the IOC - IAAF - whoever to either desist or undergo hormone therapy to bring her testosterone down to arbitrarily imposed limits.
Whether you agree with this or not, this is clearly discriminatory if you deem the excessive but naturally occurring testosterone as unfairly performance enhancing in women yet not in men. If you were fair about it you'd ask the men to suppress their hormones and level their playing firms too.
This doesn't happen and that's why the whole block fell apart
