this cyclist will be competing at 2.5 nmol/L , which, though exceptionally high/borderline unheard of for a woman, is certainly below the male range
How is it relevant that the testosterone of a man competing in the women's category is below the male range?
His testosterone is well above the female range. As are his body shape, muscle strength, heart and lung sizes, VO2 max, bone density - virtually every other physiological measure relevant to athletic performance.
The female range is relevant, not the male range.
The female body is relevant, not the male body.
This is women's sports. Sports for female humans, not male humans, however they identify or dope or decorate their bodies.
