Teratogenesis

Teratogenesis derives from the Greek teras, teratos, monster and genos, origin.

It refers to any substance which can cause abnormal development of the embryo and as a result leads to malformations. Teratogenic substances are therefore harmful to pregnant women and also potentially dangerous to other people as their effects may last over time. A woman who becomes pregnant after being in contact with these substances is therefore at risk of her child suffering from malformations.
