“…In a previous study (Bossema et al, 2012), we used a concept-mapping technique to derive three main categories of possible reasons for and against sperm donation: selfi shness (including narcissism and procreation), psychosocial drives (including altruism, detached procreation, and sexual/fi nancial satisfaction), and psychosocial barriers (including moral barriers related to oneself, one ' s spouse, the donor child, and society). Reasons for sperm donation previously cited by other studies are fi nancial compensation and altruism, including empathy and knowing infertile couples, procreation, including having as many children as possible and passing on genes, evaluating one ' s own fertility, having a physical and biochemical examination, helping clinical staff, the desire to parent, the desire not to parent, and curiosity (Pedersen et al, 1994;Lui et al, 1995;Daniels et al, 1996;Lui & Weaver, 1996;Emond & Scheib, 1998;Lalos et al, 2003;Almeling, 2006;Ernst et al, 2007;Ekerhovd et al, 2008;Ripper, 2008;Thorn et al, 2008;Riggs & Russell, 2011). Some of the reasons identifi ed by previous studies only apply to sperm donation in formal settings, such as receiving a physical and biochemical examination and helping clinical staff, whereas other reasons may apply more to sperm donation in informal settings, such as the desire to parent.…”
