I'm gonna say yes. In the end, it's best for the parents and the children. If the parents are desperately hoping for one gender and get the other, they may not be as loving towards their child. Conversely, it also benefits them by making them happy. In the end everyone wins.
I don't think this will even cause problems on the large scale. If people lean towards one gender, then the other will become ever more valuable (in a utilitarian sense).
I'm also for testing for genetic disorders, but against selecting "the best of the bunch" like they do in Gattaca. As long as the baby is healthy and happy then all is well.
One possible psychological impact to the children is when they find out they had their sex chosen. Of course the reaction will differ from person to person, and it could have a possibly large effect on some people. not sure to be honest but still a possibility.
Well I don't think that's a problem. As far as I know, you don't 'have your sex chosen'. It is rather the case that 'you' are chosen, out of a pool of XY (male) and XX (female) chromosome 23s.
If this was allowed, China => 85% male, 10% female, 5% genderless supercomputer geniuses... possibly psychic.
This. Some countries would end up with insane Male to Female ratios. However I think everyone should have to right to make decisions about their children.
But what about wanting to continue your genetic line? If there are more females than males in the world then that's an incentive to have a boy, where as vice versa that's an incentive to have a girl.
I guess if necessary there could also be government incentives; we would need to keep a closer eye on the number of each gender.
Besides, we are moving towards a world of gender equality (at least I hope so), and apparently even countries like China are not as male-centric (in terms of wanting sons instead of daughters) as they used to be.
