Have to disagree with you.
Most reputable clinics will not treat the babies with anything but tender care. Implantation does not always take but that is part of nature.
The days of implanting numerous babies in the hope that one takes is a thing of past for reputable places.
And as someone who is trying to adopt I can tell you that it is expensive and risky. Adopting from overseas is even more expensive and risky.
I know what you mean by the daunting difficulties of adoption. We went through a very frustrating process with it, and finally adopted from Russia. The cost? I always tell people "As much as the new siding and windows on our house," which gives them a ballpark figure.
It's very understandable why people are tempted to do IVF, but it's really morally unjustifiable. It demeans the beginnings of life into a commercial transaction and a lab project. The law has already ruled (in the Maryville case) that the embryos are property: the first time human beings have been considered "property" since the Civil War.
