Intrauterine (within the womb)growth retardation is most closely associated with which teratogen?

D)Tetracycline

Question

Quizplus · Accepted Answer

Nicotine is the teratogen most closely associated with intrauterine growth retardation. Nicotine constricts blood vessels, reducing the amount of oxygen and nutrients delivered to the developing fetus, which can result in growth restrictions. Alcohol can also lead to growth retardation, but the question specifically asks for the teratogen most closely associated with this outcome, which is nicotine. Aspirin and tetracycline are not typically associated with intrauterine growth retardation.
