  One response to the first argument has been to suggest that we could, under certain conditions, view all research embryos as potential children in the relevant sense. If all research embryos were included in a lottery in which some of them were donated to individuals for reproductive purposes, all research embryos would have a chance at developing into mature humans (Devander 2005). Since those who oppose creating embryos for research would likely maintain their opposition in the research embryo lottery case, it is arguably irrelevant whether embryos are viewed as potential children when they are created. Of course, research embryos in the lottery case would be viewed as both potential children and potential research tools. But this is also true in the case of embryos created for reproductive purposes where patients are open to donating spare embryos to research.
