My main question in this article is as follows: "to which extent CULTURAL DIVERSITY should be permitted to influence bioethical judgments?" There are CULTURAL heritages, values and traditions which are acceptable and respectable and there are ones which are not so. In this article I concluded that our reasoning based on common ethical sense can guide us through such differentiations. Human dignity as a common notion among most alive cultures and religions thorough the world, can be relied for sketching a plan for further dialogues in this regard.
