In its early years, Jewish medical ethics addressed a range of ethical dilemmas,[1] as well as general questions about the professional ethics for doctors.[2] Major issues have included abortion, artificial insemination, brain death, cosmetic surgery, euthanasia, genetic screening, hazardous medical operations, circumcision, oral suction in circumcision (metzitzah b'peh), organ donation, psychiatric care, and smoking cigarettes. In recent years, Jewish bioethics has examined questions of medical technology, the allocation of medical resources, and the philosophy of Jewish ethics.[3]
