Organ transplants are an effective treatment option for organ failure. The most important factor limiting this practice, which is widely used today, is the insufficient level of organ donations. In the face of the lack of organ donation and long waiting lists, patients see traveling to another country and commercial transplantation as a solution, and this has created the concept of transplant tourism. Organ transplant tourism, which violates international conventions, laws and patient rights, has brought important ethical and legal problems. In this study, it is aimed to examine the ethical problems and dilemmas caused by organ transplant tourism, which is increasing day by day all over the world. In the study, the most discussed ethical issue regarding donation from living donors, giving money to donor in return for donation and the legal and ethical dimensions of organ transplant tourism are mentioned. Within the scope of the study, the transport tourism market and the legal regulations of the countries were examined; organ transplant tourism has been studied in detail from the perspective of health ethics. This review study has been prepared by discussing the ethical dilemmas created by using a vulnerable population, even if financial interests are considered. It is an inevitable fact that ignoring ethical factors in organ transplant tourism harms both the recipient, the donor and the health systems in many ways, but it is a practice that causes dilemmas due to the possibility of benefiting the recipient. Considering the ethical dilemmas experienced, it is recommended that countries take action with practices that increase organ donation rates and reduce interest in transplant tourism.
