The Man who sold the world
Sorry medical since would disagree with you there , as stated many woman and men are XY (if female) and XX if (male) while having what would be considered all "normal" reproductive organs , and even then you have people who believe they are the incorrect gender (who's brains development appear to match more the opposite sex).
Its not easy , hence the large amount of tests they had to do .
So what is the answer when it comes to women competing against other women and men v men of course?
