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 …

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.

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.

2025年1月6日 · What is a teratogen? A teratogen is something that can cause birth defects or abnormalities in a developing embryo or fetus upon exposure. Teratogens include some medications, recreational drugs, tobacco products, chemicals, alcohol, certain infections, and in some cases, health problems such as uncontrolled diabetes in pregnant people.

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

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:

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 …

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.

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.

In this chapter, we provide an overview of the basic principles of teratology, beginning with its definition, the critical point for teratogenesis to occur and the most evident etiological agents to improve the understanding of this science.Teratology is a recent science that began in …
