The terminology of the Church has been to say that he took flesh from the Virgin. His flesh was not created "de novo" and inserted into her womb, and she wasn't just some kind of "surrogate mother." She was Christ's mother in the flesh.

Thanks for the clarification. If I'm following you, then this is my view as well. It's interesting to note that some of His, er, flesh could not have come from Mary. :) She didn't have the chromosomes for Jesus to be male.

All of the raw materials for making chromosomes, including making a Y chromosome, are in any woman's body. Things just need a little rearranging -- which shouldn't be that hard for God. That said, we really do not and will not know any biological details.
