By introducing new assisted reproductive technologies to the scientific world, the ethical issues are drawn. One of the issues is anonymous donation of gamete. Each country has its own law for anonymous donation. Some permit it and some don't. Antagonists introduce some reasons against it such as the right to know, necessity of knowing medical background, avoiding incest, decreasing the level of confidence/identity problem of child and analogy between adaption and anonymous donation. Pros have some reasons such as unimportance of genetic relation, protecting family unit, protecting child and parents against society's reaction, destroying child-parent relation, reproductive liberty and privacy, creating new kinds of family, creating training system for the child and decreasing child's stress about genetic relation. A library research method has been used and both English and Persian sources have been considered.
