Why is Pregnancy a Critical Period for Toxicology Studies?
Pregnancy is a period of rapid development and physiological change, making it a sensitive window for potential toxic effects. The placenta acts as a selective barrier, but some substances can cross this barrier and reach the fetus. The developing fetus can be particularly vulnerable to certain chemicals due to its immature detoxification systems and rapidly dividing cells, which can lead to birth defects, growth retardation, or even fetal death.
