A court battle over the two frozen embryos that she and exfiance nick loeb created through in vitro fertilization. Loeb and vergara are now split, but he wants control of the embryos writing in the new york times, in my view, keeping them frozen forever is tantamount to killing them. Loeb wants a surrogate to be implanted with the embryos so he can raise the babies on his own. But in a statement to e vergaras Attorney Says she is content to leave the embryos frozen indefinitely as she has no desire to have children with her ex. An agreement both partners signed states any change to the embryos must be mutually agreed to. In Court Documents loeb argues the agreement doesnt state what would happen in the event of their separation. Ultimately the agreement may not matter. Unless there is a compelling reason to force somebody, you know, to potentially become a parent, the court has decided with sofias side. Reporter loeb asks when we create embryos for the purpose of life, should we not define them as life rather than as property . It sounds like hes trying to bring this very fiery philosophical religious debate into the courtroom. Hes really trying to hang his argument on the idea that these are little people, and whatever else happens, they ought to become bigger people, that is to say, babies, but courts have never recognized, never, embryos as people.
