I think it comes down to the hormones, not the presence or absence of particular parts.
And genetics as well. Look this person has high levels of testosterone and yet within “normal” range for females. May well have extra chromosomes we will see. It still does not address the issue of what category such a person should compete in when others do not have that ‘advantage’. Testosterone and other such hormones ( ynthetic and other wise) are banned from use. Athletes are stripped of medals and titles all the time for this. This will continu8e to be a thorny question and I am not sure that the international governing bodies of various sports are equipped to deal ith it.
