Research on human embryos and embryonic stem cells appears to offer great health benefits for the future. At the same time, controversy over embryo destructive research is reminiscent of the disputes over abortion. What should we think about the moral and political permissibility of research and medical technology that destroys human embryos? And is this controversy really the same as the abortion controversy? In this paper, I discuss the moral and political questions surrounding embryo research, and the ways in which this research is different from, and similar to, abortion.
