Fertility clinics typically generate eight or nine embryos per pregnancy, of which only the healthiest looking are implanted. The rest are stored, and ultimately, most are destroyed. The number of embryos disposed of by clinics is not known because there is no national authority that gathers the statistics. In Britain, however, the Human Fertilization and Embryology Authority has reported that some 50,000 babies have been born through in vitro fertilization since 1991, and 294,584 surplus human embryos have been destroyed. According to the American Society for Reproductive Medicine, about 100,000 children have been born in the United States by in vitro fertilization, or twice the number in Britain, implying that some 600,000 embryos would have been destroyed if American clinics followed the same five- year storage limit used in Britain. Only a small fraction of the discarded embryos would provide as many stem cells as researchers could use. But opponents of stem cell research, who condemn scientists for destroying embryos, seem less eager to criticize the clinics and the infertile couples who seek their help. . . . The anti-abortion movement "has tried to draw a clear and bright line at fertilization," said Dr. Thomas Murray, director of the Hastings Institute in Garrison, N.Y. "Until now, they have been able to avoid having the question called. Embryonic stem cell research has called the question for them. And what we are seeing is that some politicians who have strongly supported the pro-life position now acknowledge they do not accept fertilization as the clear and bright line."
