Assisted Reproductive Technologies (ARTs) have been practiced in Islamic societies within married couples since their introduction. However, there are divergent views over the issue of third-party donation among Sunni and Shia scholars. This paper illustrates the different perspectives of Shia Muslims surrounding, sperm, egg, and embryo donation and ethical aspects thereof. The study reveals that there are different views regarding sperm, egg, and embryo donation among the Shia religious leaders around the world. Many Shia religious scholars, including the Iranian supreme (...) religious leader Ali Hussein Khamenei allow sperm, egg, and embryo donation with certain conditions. However, the conditions stipulated by Shia religious scholars contradict the ethical and legal practices of sperm, egg, and embryo donation. Regarding sperm and egg donation, they declared that the donor child would inherit from a third-party donor and the commissioning parents would be adoptive parents. Thus, according to them, donor anonymity is impossible. Moreover, the Iranian act on embryo donation did not stipulate the right and responsibilities of the donor child and recipient couples and did not clarify the nature and number of embryos that can be donated and implanted. The paper argues that the lack of laws and guidelines on sperm, egg, and embryo donation raises many ethical problems. Based only on religious rulings, third-party donation has been practiced without foreseeing the well-being and safety of donor children, donors, and recipient couples. (shrink)
