Teratology Define the term Teratology Teratology refers to the study of abnormal fetal growth. Teratogenic prenatal exposures arise from: infectious agents, chemical and drug agents, metabolic or maternal causes (such as phenylketonuria and diabetes), and physical agents (such as heat, ionizing radiation, and mechanical factors) (Jelinek, 2005). Inbred abnormalities occur commonly, with 2-3% babies, both live and stillborn, as well as aborted fetuses having structural abnormalities. Furthermore, about 10% of infants have
