Quizplus · Accepted Answer

Studies on the use of DES by pregnant women showed that the effects of teratogens may not be apparent until long after exposure, as daughters of the women who took DES during pregnancy had an increased risk of reproductive system abnormalities and cancers many years later in adulthood. This highlights the importance of long-term follow-up and monitoring of individuals potentially exposed to teratogens.
