1. 3. Even if the child is competent to give informed consent, one could still require parental authorization under the notion of family autonomy (See Part V). Thus, even the competent child's autonomy would not be adequate to justify his participation as an organ donor.
2. Organ donations can be classified into categories based on risk: minimal (low) risk, a slight increase over minimal risk (moderate risk), and significant risk. The distinctions will depend on such factors as the procedural risks that the harvesting entails (e.g. the type of anesthesia), the reversibility of the donation (e.g. bone marrow replenishes in several months whereas a kidney is never regenerated), and the long-term morbidity.
3. 20. See Purdy, supra note 19.
4. 9. I will expand this argument in section six, below, to require an intimate relationship between the authorizing parents, the child-donor and the recipient.
