Teratogeenid

Teratogeenid, also known as teratogens, are substances or conditions that can cause birth defects or abnormalities in a developing fetus. These agents can act through various mechanisms, including genetic mutations, disruption of cellular differentiation, and interference with normal developmental processes. Teratogens can be categorized into different types based on their origin, such as chemical, physical, or biological. Examples of chemical teratogens include alcohol, certain medications, and environmental pollutants like mercury and pesticides. Physical teratogens encompass factors like radiation and extreme temperatures, while biological teratogens include infections and genetic disorders.

The effects of teratogens can vary widely depending on the stage of fetal development when exposure occurs. Early exposure, typically during the first trimester, is often more critical as it coincides with the period of organogenesis, when major organs and structures are formed. The severity of teratogenic effects can range from minor abnormalities to severe congenital defects, impacting the fetus's physical, cognitive, and emotional development.

Prevention and management of teratogenic exposure involve various strategies, including public health campaigns to educate individuals about potential risks, regulatory measures to control the use and release of harmful substances, and medical interventions to mitigate the effects of exposure. Early detection and intervention programs are also crucial for identifying and addressing potential teratogenic issues in pregnant individuals. Understanding the mechanisms and effects of teratogens is essential for developing effective strategies to protect fetal health and promote overall well-being.
