Teratogens
agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm (drugs, AIDS, STDS, rubella, etc.
Teratogens are substances, agents or conditions that can interfere with fetal development during pregnancy and have the potential to cause birth defects or abnormalities. The timing and intensity of exposure to teratogens during prenatal development can have a significant impact on the severity and type of abnormalities caused. Some common examples of teratogens include:
1. Alcohol: Drinking alcohol during pregnancy can lead to fetal alcohol syndrome (FAS), which can affect the child’s physical and cognitive development. The severity of the symptoms can range from mild to severe.
2. Tobacco: Smoking during pregnancy can increase the risk of premature birth, low birth weight, and sudden infant death syndrome (SIDS).
3. Drugs: Illicit drug use during pregnancy can have a wide range of adverse effects on fetal development. For example, cocaine use can increase the risk of fetal death, premature labor, and low birth weight.
4. Environmental toxins: Exposure to environmental toxins, such as lead and mercury, can interfere with fetal development and cause birth defects.
5. Infections: Certain infections, such as rubella, cytomegalovirus (CMV), and toxoplasmosis, can affect fetal development and cause birth defects.
It is important for pregnant women to avoid exposure to teratogens whenever possible. If a woman is exposed to a teratogen, seeking medical attention immediately is critical to determine the potential risks and necessary steps to minimize the damage to the fetus.
