Teratogenesis refers to the abnormal development of an embryo or fetus. Some common causes of teratogenesis include genetic defects, maternal illnesses and infections during pregnancy, and exposure to certain medications, chemicals, or radiation. Factors like smoking, drinking alcohol, or using illegal drugs during pregnancy can also potentially cause birth defects or developmental issues in the developing fetus.
