Today and with the advancement of medical science, the issue of protecting the health of the fetus has become more and more of a concern for actors in the field of health and legislation. On this occasion, fetal abuse is not limited to physical violence that causes abortion or damage to their members. Rather, it includes many of the risk behaviours by which a pregnant woman during pregnancy can cause death, fetal illnesses, and fetal disorders. In this regard, the United States, along with the relative ban on abortion, has provided suitable criminal protection against other abuse to the fetus, also known as the Protection of Unborn Children. In addition to the federal area, this issue has been further taken into acount in some states like South Carolina. In this regard, the national criminal justice system has failed to pay attention to the fetal negligence or failure although it has provided a supportive approach to violence against the fetus. Therefore, this study aims to provide a supportive strategy by analysing and comparing the fetal abuse status in the criminal system of the United States and Iran.
