teratogeenne

Teratogen is a term used in the field of toxicology to describe any agent that causes birth defects or other developmental problems in an embryo or fetus. These agents can be chemical, physical, or biological in nature. Teratogens can affect various organs and systems, including the brain, heart, limbs, and internal organs. The effects of teratogens can range from mild to severe, and the severity often depends on the timing of exposure relative to the critical periods of organ development.

Exposure to teratogens can occur through various routes, including ingestion, inhalation, or absorption through the skin. The most well-known teratogens include alcohol, certain medications, and environmental pollutants such as pesticides and heavy metals. The study of teratogens is crucial for understanding and preventing birth defects, which are a significant public health concern.

Research on teratogens involves laboratory studies, animal models, and epidemiological studies in humans. Understanding the mechanisms by which teratogens cause developmental abnormalities helps in identifying safe exposure limits and developing preventive strategies. Public health measures, such as regulations on drug use during pregnancy and environmental monitoring, are essential in minimizing the risk of teratogenic exposure.
