An abusive man can try to prevent a woman from leaving him by getting her pregnant. Even if she leaves she'll have to continue to interact with him if he gets partial custody. He can also threaten to make sure she has her child taken away if she leaves him and threaten to lie to the court about her fitness as a parent. This works better if the local religion or government is anti abortion.
