The thing is, there is an assumption that IVF will produce a raft of embryos to choose from, which just isn't the case. Many people are lucky to have one or two viable embryos after producing 10, 16 or even 23 eggs. Can you imagine looking at the two and say "Well that one with the brown eyes can go in the bin - transfer the one with the blue eyes"? Hello? It's human life we're talking about here!

Anybody seen that film called Gattaca? It's precisely about this - how genetic screening becomes a method of persecution and exclusion. This cosmetic IVF is the first step towards that kind of society...

OP.
