Are there, or have there ever been any humans that could reproduce both as a male and as a female? And if not, have there at least been any that had both types of sex cells, sperm and eggs?

There are plenty of people with some sort of intersex traits. I know that there is usually a strong push towards full of one or the other, so I wouldnt be TOO surprised if its truly never happened. Still, my bet would be that there has been.
