A synthetic estrogen drug that was once given to pregnant women to prevent miscarriage, but was later found to cause serious health problems in their children.
From 'diethyl' (two ethyl groups) + 'stilbene' (a chemical structure) + 'estrol' (relating to estrogen). Synthesized in 1938 by Belgian chemist Edward Charles Dodds as an artificial version of the female hormone estrogen.
DES is one of medicine's darkest cautionary tales—millions of pregnant women took it thinking it was safe, but decades later their daughters developed rare cancers, earning it the nickname 'the thalidomide of hormones' and teaching the world why we need rigorous drug testing.
DES was marketed (1940s–1970s) as a miscarriage preventative for pregnant women, though evidence-based medicine had limited support. Women and daughters of exposed mothers experienced severe adverse effects, yet pharmaceutical promotion prioritized profit over safety monitoring.

The harms of DES disproportionately affected women and their children; their advocacy for recognition and medical support redefined pharmaceutical accountability standards.
