KK: /tɛrəˈtoʊdʒənɪk/
Relating to substances or factors that can cause physical defects in a developing embryo or fetus.
Certain medications can be teratogenic, leading to serious birth defects if taken during pregnancy.
Teratogenic is formed from "terato-" (from Greek "teratos", meaning monster or malformation) and "-genic" (from Greek "genes", meaning born of or produced by). The word describes substances that can cause malformations or abnormalities in developing embryos or fetuses.
Think of 'terato-' meaning monster or malformation, and '-genic' meaning produced by. This helps you remember that teratogenic refers to something that produces malformations.
