As of 2011, about 90,000 people were reported to be waiting for a new organ in the United States.[1] On average, an individual will wait three and a half years for an organ to become available for transplant.[1] There is a worldwide shortage of organs available for transplantation,[2] yet commercial trade in human organs was at one point illegal in all countries except Iran. The legal status of organ trade, however, is changing around the world. For example, in 2013, both Australia and Singapore legalized financial compensation for living organ donors.[3][4]
