It's funny that embryo selection occurs when you freeze a collection and embryos and pick the ones that survive the thaw. Chinese scientists have done studies on this effect - the resulting children are considered to be extremely healthy, much more than normal. It's one of those border cases that gets me all giddy. Whatcha gonna do, ethicists; stop storing the embryos completely or find a way to do it without freezing? Present the damaged ones? Etc.
