Abstract

Fresh embryos resulting from in vitro fertilization, including many of poor quality, can provide sources of human embryonic stem cell lines. We consider why some donate such embryos for this research, address relevant ethical and policy issues, and present core guidelines for fresh embryo donation based on those of Canada.
