I think this needs a topic in itself.
We are fast approaching a time when having a child is going to be considered to risky to leave up to the vagaries of nature. With the human genome program nearing completion it is going to be possible in the near future to design the baby you want to have. This won't be just one free from abnormalities, but basically the best combination of "desirable" characteristics possible from the two "parents".
It may sound like this is a choice that some people will make who can afford it, but in the future the pressure will become great to have a designer baby. Insurance companies will offer better deals for those they know are free from flaws that may end up costing them money, employers will want to employ those humans that they know possess the right traits in their genetic profile. In the end it will become almost compulsory to design your baby, rather than leave it up to nature.
This will of course lead to an incredible gap between the have and the have nots. The situation in films like Gattaca and the social classes of "a brave new world" are not too far away. If you want to read more on this stuff a lot of these ideas come from a guy called Peter Vardy who has a lot of interesting stuff on ethical issues like this.
