THANK YOU! Now I remember! - Ok, so lets pretend that an orc gets a human woman pregnant. And she has a girl orc (it's a 50-50 thing, unless its some misshapen creature who isn't developed enough to be either gender). Paradoxical, aint it?

I asked a friend of mine who's a doctor if it's possible to somehow change the genes of a person to make it impossible for girls to be born. This is what she told me:
Women have X+X chromosomes; men have X+Y chromosomes. An embrio always gets an X chromosome from its mother. It could get either a Y or an X from its father. The chromosome it gets from the father determines the gender. There is no known way to controll which chromosome will be given. Also, you cannot completely eliminate the X chromosome - you'd get a 'vegetable' person (such orcs are useless).

Conclusion: there must have been orc-girls, and therefore orc-women.
