Ramadan fasting and transplantation: current knowledge and what we still need to know.

Ramadan fasting is one of the most appreciated Islamic rituals in Islamic culture.

In this literature review we review the existing data on this issue and attempt to reach to a conclusion on what we know and what we still need to know.
