In general, the greatest vulnerability to teratogens occurs during the embryonic period of prenatal development.

  • A teratogen is something that, when exposed to a growing embryo or fetus, can result in birth defects or other abnormalities.
  • Teratogens include certain pharmaceuticals, illicit substances, tobacco, chemicals, alcohol, certain illnesses, recreational drugs, and in rare situations, medical conditions including uncontrolled diabetes in pregnant women.
  • Ten to fourteen days after conception, teratogens can start to damage the growing embryo.
  • There are times when the developing organ systems exhibit greater sensitivity to teratogens during embryonic development.
  • Teratogens can also have an impact on pregnancies and result in issues like premature labor, spontaneous abortions, or miscarriages.
  • Physical agents, metabolic circumstances, infections, and finally, medications and chemicals, are the four categories into which teratogens are divided.
