As a subject matter expert in the field of developmental biology and teratology, I'd like to provide an in-depth explanation of what a teratogen is and give an example.
A teratogen is a term used to describe any substance, environmental factor, or condition that can cause abnormal development in an embryo or fetus. The impact of a teratogen can range from minor physical anomalies to severe cognitive and physical disabilities, or even death. It is crucial for pregnant women and those planning to conceive to be aware of potential teratogens to minimize the risk of birth defects.
Classes of Teratogens include a variety of agents:
1. Radiation: Exposure to high levels of radiation, such as that from X-rays or radioactive materials, can cause damage to the DNA within cells, leading to developmental abnormalities.
2. Maternal Infections: Certain infections during pregnancy can have a significant impact on the developing fetus. For example, the rubella virus, cytomegalovirus, and toxoplasmosis can all lead to congenital disabilities if contracted by the mother during pregnancy.
3. Chemicals: Exposure to certain chemicals, such as lead, mercury, and pesticides, can be detrimental to fetal development. These substances can cross the placental barrier and affect the fetus directly.
4. Drugs: Some medications, both prescription and over-the-counter, can have teratogenic effects. For instance, thalidomide, which was once used to treat morning sickness, is a well-known teratogen that caused severe birth defects when taken during pregnancy.
An Example of a Teratogen: One of the most infamous teratogens is thalidomide. Thalidomide was introduced in the late 1950s as a sedative and anti-nausea drug, primarily for pregnant women suffering from morning sickness. Unfortunately, it was later discovered that thalidomide caused severe birth defects in thousands of babies worldwide, including phocomelia, a condition where limbs are underdeveloped or absent. The tragedy of the thalidomide disaster led to significant changes in drug safety regulations and the development of more rigorous testing procedures for medications during pregnancy.
It is important to note that the effects of teratogens can be influenced by the timing of exposure during pregnancy, the dosage, and the genetic susceptibility of the fetus. Prenatal care and regular consultations with healthcare providers are essential to identify and mitigate the risks associated with teratogens.

Teratogen: Any agent that can disturb the development of an embryo or fetus. Teratogens may cause a birth defect in the child. Or a teratogen may halt the pregnancy outright. The classes of teratogens include radiation, maternal infections, chemicals, and drugs.
