How about both genders? Ever heard of a hermaphrodite\s before, just like Lady Gaga from this picture? If Ты ask me, the real problem is what personal pronoun Ты should use when Ты talk to that someone: Is it a he, или 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 Ты to decide!
Just like many before me have already established, a person that possesses both reproductive organs by genetics is considered a Hermaphrodite. So, both Genders and neither of them at the same time really. By the way, the percentage of Male and Female aspects in one's body can vary so one of them could be displayed much еще than the other !!!!
