Which is a significant ethical consideration regarding xenotransplantation?

Xenotransplantation, the process of transplanting organs or tissues from one species to another, presents unique ethical considerations, particularly concerning the risk of new infectious diseases.

This concern arises primarily due to the potential for zoonotic diseases, which are illnesses that can be transmitted from animals to humans. Introducing animal-derived tissues into the human body could inadvertently expose patients to pathogens that they have no immunity against, resulting in novel infections that could spread within human populations. This uncertainty raises serious ethical questions about the safety of such procedures and whether it is justifiable to expose patients to these risks, especially when there may be unknown consequences.

The other options, while relevant to the broader context of medical ethics and organ transplantation, do not encapsulate the significant ethical dilemmas in the same way. For example, cost is an important practical consideration but does not fundamentally challenge the ethical framework around the safety and well-being of the patient. Similarly, while the availability of donor organs is a pressing issue in transplantation medicine, it does not specifically highlight the unique ethical challenges posed by xenotransplantation. Patient consent is, of course, critical in all medical interventions, but it does not directly address the multifaceted risks associated with the introduction of animal tissues. Thus, the risk
