There are several obvious objects in the picture above such as drugs and alcohol that, if used by the mother while pregnant, could potentially cause a birth defect to her developing child. The aim of teratology is to remove or reduce a pregnant woman's contact with the teratogenic agent. This is achieved in a variety of ways, depending on the teratogen. Environmental factors, once proven to be teratogenic, often can be decreased or removed (e.g., methyl mercury poisoning). A vaccine may be developed against infectious diseases. The use of drugs during pregnancy should be limited Author: Kerstin Strömland.

Teratogens act via a specific mechanism on developing cells and tissues to initiate a cascade of altered developmental events. Teratogenic effects are dependent on the nature of the teratogen, including chemical properties of the chemical, route of exposure, maternal/fetal bioactivation, placental transport, etc.
Teratogens and their effects on pre-natal development In this essay we will look into what teratogens are. The different types of teratogens, and how much of a role they play on the pre-natal development, and the foetus.
Also how the teratogens that impacts us in the womb, can also affect our bodies and our minds for the rest of our natural lives. Effects of teratogens during this period of developmental often times results in an “all or none effect.” That is, the effect of the teratogen, if it is to have any effect, will be so profound as to cause a spontaneous abortion.
