As far as IVF goes I think that that is a problem also To waste the embryonic potential for a full and healthy life so that one can become pregnant on command equates in my view to murder for your own selfish ends!

For those who use the waste and justify it is similar to the guy who sees an old broken down car on the side of the road and removes the bumpers saying to himself "well, it was broken anyways so no one will mind" all the while forgetting that it wasn't his in the first place!
