I've been looking all morning and I cannot find links to the reporting of any scientific inquiry that has been done into this prior to the guidelines being issued. From where were the testosterone levels derived - how was the limit set? What other factors (as in Cote's list above - muscle mass, erythrocytes, hemaglobin, biomechanics etc) were considered as potentially having an impact, and how and when were they ruled out? What tests were run to establish the lack of advantage being born male confers? Where is the evidence showing a range of examples looking at transitions close to puberty versus transitions in full adulthood - what are the differences, if any? How was this decision balanced against the issues raised by the cases of Caster Semenya and Dutee Chand?
Also, when weighing up the fairness to trans athletes, how and when was this balanced against the existing values in the Olympic charter, specifically those relating to women in sport? ( mission statement )
Highlights of the charter:
to act against any form of discrimination affecting the Olympic Movement
To encourage and support the promotion of women in sport at all levels and in all structures with a view to implementing the principle of equality of men and women
Mind you, I suppose I shouldn't be surprised. They were completely ineffectual about the Saudis approach to their women athletes. It seems to be a largely theoretical commitment to women in sport.
