Teratogens

Teratogens are harmful exposures that a fetus can be exposed to when they cross the protective

The quality of life for these children is unfortunately not the best. They can have limb, facial, and organ defects, and will have stunted physical growth throughout young adult life. Prenatal exposure can also have a negative effect on motor skills, especially fine motor tasks such as writing and balancing. The disabilities depend on the mother and her drinking habits. The children of heavy drinkers while pregnant, have many more developmental problems than of those whose mother was a light drinker. The most common problems among these children with alcohol exposure are with balance, coordination, and how they are able to play and handle a ball.

Considering the multitudes of things that could go wrong during a pregnancy, why would mothers consume alcohol despite the warnings of possible birth defects? Many are familiar with the "Just Say No" campaign spearheaded by Nancy Reagan in the 1980 's to prevent drug and alcohol use among teens. However, many turn a blind eye to the warnings of the surgeon general stating alcohol consumption during pregnancy can result in birth defects. When a pregnant woman consumes alcohol, she puts her fetus at risk from mild to severe physical, mental and cognitive disabilities. Fetal alcohol spectrum disorder (FASD) is the term that is used to describe an array of disorders that occurs as a consequence of women consuming alcohol during pregnancy. There are many types of FASD including fetal alcohol syndrome (FAS), partial fetal alcohol syndrome, alcohol-related birth defects(ARBD), alcohol-related neurodevelopment disorder(ARND), and neurobehavioral disorder associated with prenatal alcohol exposure. Although alcohol consumption during pregnancy is ill-advised, throughout the United States mothers continue to drink during pregnancy. Being FASD is the most preventable of developmental disabilities, I will examine the irreparable consequences of alcohol consumption during pregnancy and its behavioral, physical, cognitive and educational implications on the fetus and the family.

According to, “Teratogens and their effects on Unborn and Nursing Infants,” published by The University of North Texas, there is a list of common teratogens that are known throughout the world and many reasons that lead to a child having chances for these teratogens. According to Kathleen Stassen Berger, writer of, “The Developing Person through Childhood and Adolescence,” she defines behavioral teratogens to be known as agents and conditions that can harm the prenatal brain, impairing the future child’s intellectual and emotional functioning. The teratogen known for behavioral is known to affect the brain in some occasions if damage is affected a lot more so invading the brain and the child intellectuality to function

A teratogen is a substance that acts as a toxin that can cause a birth defect. A teratogen can be a prescribed medication, a street drug, alcohol use, or even a disease present in the mother that can cause an increased risk for the baby to be born with a birth defect. Some teratogens may cause birth defects that are noticed immediately at birth and some you can’t determine for several years. Usually the more and longer the developing fetus is exposed to teratogens the worse the consequences will be.

Alcohol is known as one the most dangerous teratogens. Every time a pregnant woman drinks, she allows alcohol to enter her blood stream and make its way into the placenta. Unlike the mother, the fetus is unable to break down alcohol that makes the blood alcohol level of the fetus the same or higher than the mother (Burk, 2013). Fetal alcohol syndrome (FAS), and prenatal alcohol exposure (PAE) are considered some of the most serious consequences of maternal drinking during pregnancy. Children can exhibit physical abnormalities such as a flat mid-face, a thin upper lip, a smooth groove between the nose and upper lip, along with growth retardation, and cognitive difficulties. The affected children also have cognitive difficulties which include intelligence, language, memory, and learning (Wacha & Obrzut, 2007).

Almost any man made substance could be considered a teratogen to some extent. However, the key question is at what level is a substance to be considered a teratogens because, to officially be classified as a teratogen it has to alter the embryo from an unnatural growth or lack of. From the Life Span text, it lists the most researched teratogens as

According to the Centers for Disease Control and Prevention (CDC), birth defects results in one of every 33 babies. Teratogens account for 4 out of 5% of birth defects when chemical and drugs are in the system. The use of this or even infections can cause abnormal fetal development.

A teratogen is any agent or factor that can disrupt the development of an embryo or fetus, which may cause a birth defect or malformation. Whether it is a medication, disease or drug, when the mother is exposed the chances of problems arising with the baby increase. Only ten to fourteen days after conception teratogens can affect the fetus. At that stage in the pregnancy the egg has already been fertilized and attached to the uterus. This is known as the embryonic stage where if health isn’t a priority complications can occur. At this point the mother and embryo share a common blood supply therefore anything the mother does affects the embryo. This is also the stage in which most miscarriages occur. There are numerous teratogens but two

The timing of prenatal exposure to the teratogen, the dosage of the teratogen, and the individual differences in sensitivity to a particular teratogen. Alcohol is one of the most common and preventable causes of birth abnormalities. The amount of alcohol consumed during pregnancy, the timing of drinking, and individual differences in sensitivity to alcohol all play a role of the extent and nature of effects caused by prenatal exposure to alcohol. A child whose mother drank during pregnancy is likely to have Fetal Alcohol Spectrum Disorders. Children with FASD are likely to have behavioral problems and lower IQs, which results in them struggling in school and contribute to poor social skills. Drinking during pregnancy can also compromise physical

Teratogens refers to any environmental agent, such as dose, heredity, negative influences and age that can cause damage during the prenatal period (Berk, 2014). Serious defects can occur during the embryonic period where the “ground work is laid for all body structures and organs” (Berk, 2014, p. 63). During the fetal period teratogens can do minimal damage; however, organs such as brain, eyes, ears, teeth and genitals can still be affected (Berk, 2014).

Teratogens such as alcohol and tobacco could potentially affect normal fetal developmental causing developmental disorders and diseases.5,6

Why it is important in our society to know what teratogen is, and some ways to prevent this birth defect in our society. Teratogen is a agent that disturbs the development of an embryo. Well, what exactly causes these disturbances in the embryo? By taking medicine during pregnancy, medicine prescribe to new mothers can cause abnormality in pregnancy. Although many women take medications during pregnancy, the medicine prescribe can be harmful. A example may be a woman during pregnancy comes across morning sickness; therefore, she may ask her doctor to prescribe medicine to treat her morning sickness. A common medicine to take during the 60's was thalidomide. However, over the years researchers found that thalidomide caused partial absence

Alcohol is a type of teratogen, which is an agent that can caused birth defects to occur. The timing and the amount of exposure to a teratogen is crucial when it comes to a pregnancy. A mother’s use of alcohol can greatly affect an unborn child. The timing at which the effect of teratogens varies from person to person, but the time when the teratogens have the largest effect typically occurs during the periods of rapid prenatal development. Mothers who are pregnant, or who wish to become pregnant, should avoid consuming alcohol because the teratogens can affect the mother’s eggs. It is true that there are certain stages in the pregnancy where a certain amount of exposure to teratogens will only have little impact, but there is still some form of result. When
