Quizplus · Accepted Answer

Thalidomide is a well-known teratogen that was prescribed in the 1950s and 1960s to treat morning sickness in pregnant women. However, it was found to cause severe developmental abnormalities in their babies, including limb deformities, heart defects, and other malformations. The use of thalidomide during pregnancy led to changes in regulations for testing and approval of drugs, and it continues to be a cautionary tale for the potential harm that can be caused by exposure to certain substances during fetal development.
