The official explanation from Kenkou Cross, the series author, is that constant infusion of male spirit energy, or mana, repairs the undead body as it accumulates. The more spirit energy an Undead-type mamono absorbs, the better the condition of their body becomes. And while it would likely take quite a bit, eventually the body can even be repaired to the point that the zombie or ghoul or wight or jiangshi can bear children.

That said, I would personally expect that an Undead pregnancy would be rarer than most other mamono pregnancies, and mamono pregnancy in general is evidently a somewhat rare thing (much as predators in real life often have a lower birth-rate than their prey). It's something every mamono is capable of, however.

That said, the entire purpose of the setting is sexual fantasy, so... Yeah.
