What does teratogenicity refer to in relation to substances?

Teratogenicity specifically refers to the ability of a substance to cause birth defects in a developing fetus. This concept is particularly important in fields such as pharmacology, toxicology, and environmental health, where exposure to certain agents during pregnancy can lead to a variety of congenital abnormalities. Understanding teratogenicity is crucial for evaluating the safety of medications, chemicals, and environmental exposures for pregnant individuals and their unborn children.

The focus on birth defects distinguishes teratogenicity from other biological effects. For example, the ability to cause allergic reactions pertains to immunological responses, while enhancing growth relates to physiological development, and improving soil quality concerns environmental factors. Each of these aspects addresses different areas of health and environmental impact, underscoring the specificity of teratogenicity to fetal development and defects.
