I have nothing against Caster or any other athlete it her condition. The fact of the matter is when a person is born with both sexual organs, their tetes regardless if fully developed or not produces testerone at the lowest level 3 x more than any none tetes female at her highest normal level. Throw in bigger heart and oxygen consumption and you see why the IAAF finally hotten something right. Its not Caster the IAAF is targeting but the rest of female athletes who have to compete with anyone who have advantage via their testerone level.
It's no athlete fault for being born with both sexual organs but that doesn't give them the right to compete against women who will never approach their testerone levels normally.
