Diethylstilbestrol (DES, former BAN stilboestrol) is a synthetic nonsteroidal estrogen that was

first synthesized in 1938. It is also classified as an endocrine disruptor. Human exposure to

DES occurred through diverse sources, such as dietary ingestion from supplemented cattle

feed and medical treatment for certain conditions, including breast and prostate cancers. From

about 1940 to 1971, DES was given to pregnant women in the mistaken belief it would reduce

the risk of pregnancy complications and losses.
