Whoa now, do you have ovaries? do you have periods? That's a pretty big difference in body chemistry if you ask me...
That's not body chemistry, these are bodily features. Obviously transgender women don't have ovaries, that's what the hormone treatment is for.
And my guess is most female fighters use birth control to avoid getting their period in preparation of a fight anyway. (can anyone confirm or deny this? Liza maybe?
) Yes, you read that right. Birth control makes women not have their period.
