A male ovum is deprived of the full spiritual energy and dies.

Now see this would be reasonable if it weren't for a couple of details in the setting. Namely:

1. The Mamono Lord changed things so that monsters fundamentally cannot (or at least will not) kill a human via mana drain (this is explained in the Succubus Notebook, as well as MGE volume 1 stating humans are not killed by having their mana sucked out). At the very least they can readily choose when to stop feeding or to feed at all (unless they are starving).

2. A male ovum wouldn't produce much mana to feed on to begin with, making it easy for a monster's body to ignore it as a source of food.

3. Most importantly for this topic, married monsters find all male mana aside from their husband's either tasteless or disgusting and will not feed on it. This would presumably apply to her unborn son's mana provided she is married, she would be physically and mentally unwilling to feed on it.
