How about both genders? Ever heard of a hermaphrodite\s before, just like Lady Gaga from this picture? If 你 ask me, the real problem is what personal pronoun 你 should use when 你 talk to that someone: Is it a he, 或者 a she? Try IT! Maybe that won't be such a bad idea to call someone who's born both man and woman, but that's just me. It's up to 你 to decide!
Just like many before me have already established, a person that possesses both reproductive organs 由 genetics is considered a Hermaphrodite. So, both Genders and neither of them at the same time really. 由 the way, the percentage of Male and Female aspects in one's body can vary so one of them could be displayed much 更多 than the other !!!!
