Question stolen from elsewhere:
They estimate that this new genetic screening technique will cost about $500, down from around $3,000. It would pre-screen embryos for genetic abnormalities and chromosomal integrity prior to implantation, thereby dramatically increasing the odds of having a successful pregnancy and healthy baby. This would reduce cost, miscarriages, and the fear of passing on heritable disorders such as Huntington's - those embryos containing abnormalities would simply not be used.
The controversy: People fear that this is taking us one-step closer to "designer-babies." If we can screen for disorders, what else will we begin screening for? Athletic ability? Height? Etc.
Why aren't the anti-choice folks all over IVF the way they are abortion? If they truly believe that personhood begins at conception, lobby against plan B and other forms of emergency contraceptive, then why don't we hear a big stink over IVF, which also results in a lot of embryonic lives being snuffed out?
