Title summarized it. How does the pregnancy in this game work? it's in an impregnation game list I found, so I have high hopes.

Have sex with a girl for a chance to get her pregnant. The player and girl's fertility rating determines not only if the girl gets pregnant but also how many kids she gets pregnant with. A few in-game days later, she will give birth, and you can knock her up again.

The uh homunculus that are your children are needed for villages.
