Uh, here I am scratching my head! You answered your own question in the question.
Man fertilizes the egg, and the woman goes on to make the baby. Man contributes half of the genetic instructions, but the woman actually does all the work.
In Old Testament times, the connection between sexual intercourse and conception was well understood. It being a patriarchal society, they decided that the future human being already existed in miniature form inside the man, and that the man's "seed" simply found a place to grow inside the woman. Today, we realize that the parents each contribute half of the genetic instructions for the future infant.
In Old Testament times, they knew the woman did all the work, but ignored, just as you have chosen to do. If you want to make friends with women, I advise you to do an attitude adjustment.
