There are a number of things here that are disturbing to me.... the first is, why didn't the Dr.s involved say absolutely not? I think that we are stretching the boundries of ethics and making it seem like we are doing this for the good of humanity. I remember a Time article about 15-20 yrs ago that was about an Italian scientist that had successfully created 1/2 chimp 1/2 humans. He motivation was that it could be done. He was reprimanded and ordered to halt the tests and destroy the whatevers. Now we are doing the same thing again, but we have changed our reasoning to "help for humanity". If we can get pigs and chimps tp grow human body parts, then more will be available for transplants.... stretching the boundries...
the second thing that bothers me is that while their daughter is severly retarded, they are willing to subject her to cancer by giving her large doses of unrestricted (meaning not being balanced by progesterone) estrogyn. So when the little thing gets lukemia, or another type of reproductive cancer, she will suffer some more.
The parents are eventually going to be to old to care for her anyway, if she lives that long, which I guess is doubtful, so why not just hire someone to come in and turn/clean/lift her?
