Ethical Controversies in Organ Transplantation

4. Types of organ donors

The sources of organs for transplantation, i.e., living donor (related and nonrelated), cadaveric donor, and brain-dead patients. In countries where transplantation is well established, organs are sourced from living and cadaveric donors using different strategies, i.e., an opt-in (explicit consent), opt-out (presumed consent), and donation after brain death, donation after controlled cardiac death, and extended criteria for deceased donors.
