@mjg59 @lxo @quasi Genetic sex and testosterone levels are measurable, and the measurements made on Imane Khelif revealed them to be genetically male and their T levels correspondingly in the male range. Same situation for transwomen. And like I said, studies show that suppressing T doesn't diminish all advantage. Certain things are irreversible anyway, like the size/shape to which some body parts grow/change (lung capacity, Q angle, etc.) so the study results were to be expected.
