Final answer:
Diethylstilbestrol (DES) is a synthetic estrogen that was prescribed to pregnant women from the late 1930s to the 1970s. It had harmful effects on both the women who took it and their offspring, including an increased risk of cancer and reproductive issues. The situation with DES led to greater regulation of pharmaceuticals and awareness of endocrine disruptors.
Step-by-step explanation:
Diethylstilbestrol (DES) is a synthetic estrogen that was prescribed to pregnant women from the late 1930s to the 1970s to prevent miscarriages and other pregnancy complications. However, it was later discovered that DES had detrimental effects on both the women who took it and their offspring. The drug was linked to an increased risk of vaginal and cervical cancer in the daughters of women who took DES, as well as a higher incidence of reproductive issues in both males and females. The widespread use of DES and its subsequent harmful effects led to greater regulation of pharmaceuticals and increased awareness of the potential dangers of endocrine disruptors.
