Norway's approach to technology involving embryos is cautious and conservative. Norway bans in vitro fertilization for anyone except married heterosexual couples, for example. Now, after a debate involving a family that wanted a second child so they could get bone marrow to help a sick existing child, Norway has now decided to allow for genetic testing of in vitro fertilized eggs before implanting - out of the country. It won't be done here.
I have no particular opinion about the technology itself; my stance is one of a mix of admiration for the creativity and a bit of skepticism. Man will think of all kinds of things, good and bad, in the name of science or progress. What's making me write today, is a nagging feeling about the whole issue of having a new, healthy child, in order to harvest it for bone marrow to help a sick, older sibling. What does this sort of "rescue operation" say about loving all your children equally? Will the new child be loved for its own sake? What if its bone marrow can't be used after all? How do the efforts to save an older child justify performing painful procedures on a younger child who is brought into existence because of those procedures? Is this fair or loving to that new child?
I'm sure that parents who are in this situation will assure me that they will love their kids equally, no matter what, but I still have a nagging feeling that somewhere, on some level, that this reason for bringing a kid into the world is just wrong.
