I think a big factor in the cases discussed in the article is that these women were told they would never ever have their own children. Unlike women who are "infertile" (which is usually just a measure of probability, and not a binary diagnosis), women who do not have a uterus obviously understand that there isn't a probability factor for getting pregnant. But then tell a woman with such a diagnosis that there is an experimental procedure that will allow her to fully experience what she had always been told was not possible. It is more for her than just wanting a baby at that point-- the procedure offers her everything she was told she could not have in terms of giving birth to a child.
I don't doubt some level of that drive exists. What feels questionable is the sanity (?) of going to such extreme lengths to pursue it? As if there is a complete unawareness of the bigger picture.
That's one hell of an understatement. It's only the primary driving force of all successful complex lifeforms. Living things that give preference to offspring other than their own die with zero remaining trace of their existence.
