“…Patient's preference is not often that their remaining embryos have a chance at life, but rather that they can "be used in a way" (Lyerly and Faden, 2007). Therefore, the meanings of the moral status of embryos seem to be varied and context-dependent, not fixed entities (de Lacey, 2005;Haimes et al, 2008), with couples using a complex and dynamic system of embryo classification (Haimes and Taylor, 2009). Patients undergoing IVF perceive embryos simultaneously as epistemic or medical objects for research and clinical practices, and ontological objects for reproduction (Samorinha et al, 2014), with an instrumental value (Provoost et al, 2009) that should not be wasted (Luna et al, 2009;Provoost et al, 2010).…”
