The view of the three monotheistic religions toward xenotransplantation.

Xenotransplantation, transplanting animal organs into humans, may offer a solution to the shortage of organs for transplantation. This would increase the chances for scheduled, elective transplantation, even for patients currently ineligible for receiving a human organ. However, xenotransplantation raises specific ethical and philosophical issues, that is, a personal identification of the body parts with the soul and spirit, the relationships between humans and animals, and challenges related to issues of medical and social ethics. The three monotheistic religions have laws and perspectives pertaining to xenotransplantation. This scholarly review examines the theology and viewpoints of the three monotheistic religions and their concerns regarding xenotransplantation (interspecies) in terms of religious-legal rulings, the ethical considerations related to the procedure, through religious scriptures and rulings of scholars of the three faith communities. This review should be viewed as a continuation of an extensive investigation of these issues, as the field of transplantation advances toward clinical trials. It was found that there are no fundamental religious reasons presented by any of the three religions to prohibit the use of animal organs as a means of treating severe and life-threatening conditions. However, there are certain limitations prescribed by each religion relating to the treatment of the animals and the choice of organs to be transplanted.
