IN GENERAL when using medical science to enable any good thing one has tried and failed to do by means of nature, it’s a blessing not a curse. I would not want to see attempts to fertilize multiple eggs at the same time because the question arises about what to do in case of multiple successes. Trying to bring them all to term would create a problem situation, as noted. But to fertilize one with “artificial” help and then try to implant it should not be a bad thing. What I see here is an attempt, in the name of specific theological objections, to tar the whole field indiscriminately. “Look at all the troubles associated with X” does not equate to “X is ipso facto bad.”
Another scenario is that the childless couple adopt. Then, very often, they relax and are able to conceive. It’s happened innumerable times.
Yes, its not something I’m totally against. I think with the right restrictions and limitations in place, along with better understanding of genetics and how to avoid putting any potential child at risk of defects, this could be a wonderful technology. I would hope however, that adoption would remain preferable for most people in that situation. There are a lot of kids out there who need homes.
