I have some training in science and came up with an idea of why Mamono only have girl children. Mamono eat the life force found in sperm which kills them. Male sperm probably has a bit more spirit energy so they get absorbed first. However, if that was it then there would still be some male children that were lucky enough to be fertilized before the sperm got eaten. However, the developing embryo would still be in it's mother's womb which absorbs spirit energy. Any spirit energy it produces would be instantly absorbed by its mom. At the same time the fetus would be bathed in it's mother’s demonic energy. This would probably end up corrupting the embryo (no spirt energy + demonic energy = monster). So up to a quarter of the monsters walking around would have been men but got corrupted in the womb.
