This article examines the legal and ethical dimensions of embryo donation and its impact on medical law. Embryo donation, despite helping infertile couples, poses ethical (fetal rights, child identity, commercialization) and legal (parental determination, contracts, differences in international laws) challenges. This has affected medical law, increasing the need for transparent laws and accountability of medical centers. To balance scientific progress and human values, the cooperation of medical, legal, and ethical experts is essential. Articles were searched based on Persian keywords; legal, ethical dimensions, embryo donation, medical law, Iran, as well as the English equivalents of these keywords in reputable databases and citations, including PubMed, Web of Science, Scopus, Google scholar, Science Direct, SID, and Magiran. All original articles were collected and reviewed for inclusion in the study. Screening criteria were applied in three stages by applying the inclusion and exclusion criteria; 28 articles were found at the beginning of the search. In the screening stage (first 4 stages), 6 articles were excluded from the study, and in the final stage of the screening, 22 articles related to the study objective remained, which were content evaluated and included in the study. Of the most important points to note, embryo donation faces ethical challenges such as maintaining human dignity and child rights, and legal issues such as determining legal parents and contracts, which require clear laws and interdisciplinary cooperation to guarantee the rights of all parties. The advancement of this technology requires a careful balance between medical innovation and respect for human values.
