The process of forming physical abnormalities in a developing embryo or fetus.
Teratogenesis can lead to serious birth defects if certain harmful substances are present during pregnancy.
Teratogenesis is formed from "terato-" (from Greek "teratos", meaning monster or abnormality) and "-genesis" (from Greek "genesis", meaning origin or creation). The word refers to the process of abnormal development or the formation of monsters during embryonic growth.
Think of 'terato-' meaning 'monster' and '-genesis' meaning 'creation' — this helps you remember that teratogenesis refers to the creation of abnormalities or monsters during development.
