Teratogen Information

What is a teratogen?

A teratogen is an agent that can cause malformations of an embryo or fetus. This can be a chemical substance, a virus or ionizing radiation. This is closely related to a fetotoxin, an agent that causes poisoning effects on a developing fetus.

Both fetotoxins and teratogens are reproductive toxins, substances which cause damage to one's reproductive and/or endocrine system and/or a developing fetus.
