Should clinicians ask women to donate or even sell their eggs for stem cell research? Enucleated ova are crucial in somatic cell nuclear transfer technologies, but risky for women’s health. Until comparatively recently, very few commentators debated the ethical issues in egg donation and sale, concentrating on the embryo’s status. The unmasking of Hwang Woo Suk, who used over 2,200 ova in his fraudulent research, has finally brought the question of ova donation and sale into prominence. In this article we (...) offer an international comparison of recent responses to this crucial question and suggest that the levels of risk are too imprecise to enable women to give meaningful informed consent for egg extraction. What we do know of the risks also indicates that they are too high and that potential donors or sellers are not being fully informed of their extent, raising disturbing ethical issues concerning commodification, deception, coercion, and exploitation.
