Everyone should be free to choose what they want to do with their life as long as it does not harm anyone else. Some people want kids but can not have them because of medical reasons so it would be unfair to stop their partners from having kids too. . .
Everyone should have the right to have children of their own or at least with their genes, Even if they are not physically able to do so. If a woman or male is infertile, Their partner still deserves to have a child that is from both of their genes and dna.
