At least if this should be true, It will reduce bastard children and reduces fight between men and women, some men would know they are responsible for a pregnancy but still go ahead to disagree because they aren't ready to have baby(ies) due to financial crisis or other related problems .
When I saw this picture online today I was like wow, we have finally got them. Not only to fight men that are not ready to accept pregnancy but also to teach girls that are into numerous men lessons. Some ladies are so cruel to the extent of giving pregnancy of a man to another man.
I don't really know how true this could be but if so it is a good creativity and innovation.
