Fertilized egg ownership...

Anna • 38, married, ectopic jan 2015, starting first round of IVF, which worked. Little boy born in January 2017.
Who do you think should have a say in what happens to fertilized eggs? Sofia Vergara and Nick Loeb for example...they have fertilized eggs together but she isn't with him and doesn't want the eggs to go to a surrogate. He however wants the eggs and wants to be a father. If he wins should she have to pay child support? What do you guys think?
