If someone is born with both male and female reproductive organs, by genetics, what gender are they?

How about both genders? Ever heard of a hermaphrodite\s before, just like Lady Gaga from this picture? If you ask me, the real problem is what personal pronoun you should use when you talk to that someone: Is it a he, or 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 you to decide!

That would be known as hermaphroditism. So neither.

Femmale
Malefem

hermaphrodite

and to address them , its either better to address them by their name ...or use "They"

Well, it's UNGODLY rare, but at that point I'd go by chromosomes and hormone level.

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 more than the other !!!!

If some is born with both sex organs, they are (by definition) Hermaphrodite.
