NO! It may not be nice to fool Mother Nature, but it’s even worse to mess with her in this way, especially when it’s for such utterly selfish reasons, as is generally the case with these old-age/in-vitro treatments. (This one was in order to produce a male heir, which begs the sticky question of what they would have done — or did do — if the only viable fetus were a girl.) I agree with most of my fellow wOwers that the child is usually the last person taken into account, when he or she should be the chief concern. Even before this question popped up, my gut response was "YUCK." It still is.
