 Another set of issues is the negative effect that payments, or payments above a certain level, are supposed to have on the quality of consent—a concern that is closely linked to worries about exploitation. Financial incentives, it is argued, encourage people to do things that they would not otherwise do, encourage them to do things that are harmful, and make their actions, consents, and decisions less likely to be autonomous and voluntary (Resnick 2001; Steinbock 2004; Wilkinson 2013). These arguments are more often directed at paid egg donation than paid sperm donation, because the direct physical risks and the sums of money involved for eggs tend to be much greater. Thus, people have been concerned that vulnerable young egg donors might be lured into the egg market and then exploited by clinics, egg banks, or recipients. These concerns structurally parallel ones that people often have about commercial surrogacy and sex work.
