Is there a market for organ donation?

Outside of the US. Unfortunately, there is a black market outside of developed countries. The patients who have been identified afterwards have had much higher rates of infections and worse outcomes. Medicare may not pay for the anti-rejection medications if the transplant was not performed at a medicare approved center. Black market transplants are dangerous. Legitimate organ donation must be increased.
No. Paying for organ donation is illegal in th U.S. And in most other countries. There is no market but there is a need.
