I doubt it was done by a doctor, at least in US. She had worked in a fertility clinic before and who knows how it was done.

Certainly I would go after licenses of any US doctors who did this. I think there should be laws that no more than two could be implanted, regardless of fertility issues. Sometimes people are not going to be able to have children, and it is sad, but there still should be boundaries. I would hope they would decide to adopt if treatments did not work, or afterwards if they did.
