Also found in: Dictionary, Thesaurus, Encyclopedia.
a synthetic nonsteroidal estrogen used for palliative treatment of prostatic carcinoma and sometimes advanced breast carcinoma. It was formerly used to relieve vasomotor symptoms associated with menopause, and in primary ovarian failure, female hypogonadism, atrophic vaginitis, kraurosis vulvae, and female castration. Most significantly, however, it was formerly widely used to prevent threatened abortion and premature labor. The female children who were thus exposed to the drug as fetuses have tended to have a variety of cervical abnormalities and an increased risk of clear cell adenocarcinoma of the reproductive tract. Male offspring have sometimes had abnormal genitalia, epididymal cysts, and abnormal semen analyses. Regular examinations and follow-up are indicated for these individuals.

This is a synthetic estrogen drug that is used to treat a number of hormonal conditions. However, it causes problems in developing fetuses and should not be taken during pregnancy. From about 1938 to 1971, DES was given to pregnant women because it was thought to prevent miscarriage. Children of women who took the drug during pregnancy are at risk for certain health problems.
