No sources here cuz I just got home and I'm tired, but I swear there was some press recently(?) about IVF clinics fretting about egg storage/disposable for exactly this reason. I don't remember if anything came of it, but I think some IVF technicians were worried about going to jail if they, for instance, forgot to put an unfertilized egg back in the freezer and it went bad.

And then when you get to fertilized but non-implanted embryos, of course, that's when the "life begins at conception" crowd starts having their say.

Those IVF technicians seem a bit paranoid. Obviously, forgetting to put an unfertilized egg back in the freezer will hurt trust in your business, but I can't imagine anyone could successfully sue the IVF clinic on the basis that an illegal abortion had occurred.

The issue of fertilized but non-implanted embryos is already well-understood, as that is the entire basis behind opposition to embryonic stem cells and derived products. The interesting part will be to see how various religions will react if you tell them the fertilized egg will grow in an artificial womb.
