In the present study, effort has been made to represent a definition of Bioethics and to explain the relationship between Bioethics and Human Rights. Some believe that Bioethics is completely in accordance with Human Rights and there is basically no substantive difference between these concepts. On the other hand, some criticize the Human Rights and they believe that it follows the government policy and the governments manipulate the human rights. More than that, whilst trying to answer these critics, some of the codes in important and primary Documents of Human Rights related to Medical Ethics will be considered and human dignity as the interface of Bioethics and Humans Rights will be considered. In the last part, some of recent International documents and declarations which stress on the relationship of these two concepts and implementation of Human Rights regulations in biology and medicine will be reviewed. In the end according to the discussed issues, this result was obtained that the necessity of medical ethics being universal and its direct relationship with existence of human’s existence and dignity demands consideration within the universal documents and standards of Human Rights.
