A teratogen is any agent that causes abnormalities when a developing baby is exposed to it during the mother’s pregnancy. These environmental exposures can cause birth defects and other problems. Teratogens can have effects that range from mild to severe, and they are often most dangerous during early pregnancy and with excessive or prolonged exposure. Teratogens are substances that may produce physical or functional defects in the human embryo or fetus after the pregnant woman is exposed to the substance.
Alcohol and cocaine are examples of such substances. Exposure to the teratogen affects the fetus or embryo in a variety of ways, such as the duration of exposure, the amount of teratogenic substance, and. Teratogens are any type of drug, chemical or some infections that will cause an embryo to develop abnormally. Since there are so many things that are considered teratogens, the only way to protect your unborn child is to avoid them all together.
Experts have had a hard time pinpointing when, where and who these teratogens will affect. “A teratogen is an agent, which can cause a birth defect. It is usually something in the environment that the mother may be exposed to during her pregnancy. It could be a prescribed medication, a street drug, alcohol use, or a disease present in the mother, which could increase the chance for the baby to be born with a birth defect.”. A teratogen (ter-AT-uh-jen) is something that can cause or raise the risk for a birth defect in a baby.
They are things that a mother may be exposed to during her pregnancy. Teratogens can cause severe birth defects, malformations, or terminate the pregnancy altogether (Jancárková, & Gregor, 2000). The placenta is known as an effective barrier from any detrimental pathogen that can potentially hurt the fetus. Teratogens are environmental factors that result in permanent structural or functional malformations or death of the embryo or fetus. Many congenital malformations are of unknown origin, but known teratogens include drugs, maternal illnesses and infections, metal toxicity, and physical agents (e.g., radiation).
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. Teratogens are environmental factors that can contribute to birth defects, and include some maternal diseases, pollutants, drugs and alcohol.
Factors influencing prenatal risks: There are several considerations in determining the type and amount of damage that might result from exposure to a particular teratogen (Berger, 2005). A teratogen is an agent, which can cause a birth defect. It is usually something in the environment that the mother may be exposed to during her pregnancy.
It could be a prescribed medication, a street drug, alcohol use, or a disease present in the mother which could increase the chance for the baby to be born with a birth defect.
