The Pros and Cons of Iterative Embryo Selection

We can do some level of prediction of cognitive ability from DNA alone. But let me just say that our company does not offer that because it's too controversial. We're trying to stay away from the most controversial traits like cognitive ability, like height,. We're only doing the ones that really have an impact on health so I just want to clarify that. Our calculations suggest that if you have 10 embryos and you pick the one with the best health index versus random selection. You're gaining about four life years for that. So whichever one becomes your child will end up having about four extra healthy years of life than if you just randomly selected one.
