Legal Definitions - teratogen

A teratogen is a substance or agent that can cause harm to a developing fetus, leading to birth defects or other health problems. This can include chemicals, drugs, infections, and other factors that can affect the growth and development of a baby in the womb.

For example, alcohol is a well-known teratogen that can cause fetal alcohol syndrome, a condition that can lead to physical and cognitive impairments in children. Other teratogens include certain medications, such as thalidomide, which was once prescribed to pregnant women and caused severe birth defects.

It's important for pregnant women to avoid exposure to teratogens whenever possible, and to talk to their healthcare providers about any medications or substances they are taking that could potentially harm their developing baby.
