Question

Quizplus · Accepted Answer

Teratogens are substances or factors that can cause birth defects or malformations in fetuses during pregnancy. Organogenesis is the process of organ formation that occurs during the first trimester of pregnancy. Exposure to teratogens during this period can lead to severe anatomic defects. However, exposure to teratogens after organogenesis is complete is more likely to result in stunted growth because the organs are already formed and the fetus is in the growth and development stage. An enlarged cranium or death of the fetus may occur in rare cases, but it is not the most likely outcome.
