2022年10月21日 · A teratogen is a substance that interferes with normal fetal development and causes congenital disabilities. Drugs, alcohol, chemicals and toxic substances are examples of teratogens. Teratogens can also increase the risk for miscarriage, preterm labor or stillbirth. What are teratogens?

Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens and also in pharmacology and toxicology.

Teratogenesis refers to the occurrence of developmental defects in an organism caused by exposure to toxic substances during the period between conception and birth. These defects can include abnormalities in morphology, function, neurobehavior, and growth rate.

What is a teratogen? 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 include: Experts believe that teratogens can begin affecting a baby growing in the womb about 10 to14 days after conception.

2012年4月28日 · Teratogenesis is the disturbed growth process involved in the production of a malformed neonate. There are six principles of teratology as defined by Wilson since 1959 [11]. These principles guide the study and understanding of teratogenic agents and their effects on developing organisms:

2024年4月12日 · What is Teratogenesis? Teratogenesis, also known as teratogenicity, refers to the process by which congenital birth defects occur due to exposure to certain factors during pregnancy.

A human teratogen is an agent that alters the growth or structure of the developing embryo or fetus, thereby causing birth defects.

2010年2月17日 · A teratogen is any agent that causes an abnormality following fetal exposure during pregnancy. Teratogens are usually discovered after an increased prevalence of a particular birth defect. For example, in the early 1960’s, a drug known as thalidomide was used to treat morning sickness.

The article subjects range from topics on animal models to study teratogenesis and its mechanisms, bioinformatics, molecular aspects of teratogenesis as well as reviews on specific human birth defects related to environmental exposure.

2021年2月26日 · Teratogenesis refers to the induction or production of malformations in a developing embryo or fetus. Teratogens are substances that may cause birth defects. 1 The study of this type of abnormalities is called teratology and experts in this field is …
