One can hope that the updated legislation somehow addresses this. That said, it would be absolutely stunning if the previously existing law didn't simply go 'boink!' in the face of a heretofore novel circumstance. At very least, I could see the need for the courts to set a precedent if/when the first case came along.

I guess it isn't that novel anymore for a woman to donate eggs and not expect to have any rights to any resulting children.

Swapping out the nuclear DNA doesn't really complicate that.
