I think men should make females sign contracts that states neither party wants to become a parent, what are your thoughts

Im watching this tv show about mens reproductive rights. I think it is some cases unfair for a man to forced into fatherhood/ child support, such as this girl told her bf after they had discussed not wanting children and she claimed to have a medical condition that prevents pregnancy but still on the pill for medical reasons then got pregnant anyway and chose to keep the child. I thinks it's unfair in some cases (that's where it gets tricky) like when deliberately get pregnant without informing the male. It's just something to ponder. But I think it can be unfair that men have no rights and they should try contracts signed by both parties
