What is a common characteristic of teratogenic substances?

Teratogenic substances are known for their ability to cause birth defects in developing embryos or fetuses. This characteristic is crucial as it highlights the risks associated with the exposure to these substances during pregnancy. Teratogens can lead to a variety of physical and functional anomalies in a baby, which may manifest in different degrees of severity, affecting the baby’s health and development both at birth and later in life.

While some teratogens might pose other risks, such as genetic mutations or affecting certain populations, the defining trait of teratogenic substances is their direct impact on fetal development, resulting in malformations or other adverse outcomes. This understanding is essential for healthcare professionals who need to be aware of potential teratogens to mitigate risks for pregnant patients.
