I didn't know this myself: Women who have their ovaries stimulated with drugs to make eggs for harvesting risk a rare, but potentially deadly, condition called ovarian hyperstimulation syndrome. Apart from that, it's not just a matter of donating eggs, which are gametes (23 chromosomes) and therefore not human beings (46chromosomes): Researchers will use the eggs to create cloned early-stage embryos, with the ultimate hope of extracting stem cells that could treat diseases. Once again, they are obsessed with embryonic stem cells and ignore adult stem cells which can also provide pluro-potent cells. Embryos have 46 chromosomes, and have DNA distinct from their parents: embryos are human beings. To date, not a single cure has been applied to humans using embryonic stem cells, while using adult stem cells already number 72 successful human treatments. 72-0.
