Diethylstilbestrol:

DES (in tablets up to 5 mg) was approved by the United States Food and Drug Administration (FDA) on September 19, 1941 for four indications: gonorrhealvaginitis, atrophic vaginitis, menopausal symptoms, and postpartum lactation suppression to prevent breast engorgement. The gonorrheal vaginitis indication was dropped when the antibiotic penicillin became available. From its very inception, the drug was highly controversial.

In 1941, Charles Huggins and Clarence Hodges at the University of Chicago found DES to be the first effective drug for the treatment of metastatic prostate cancer. [9][10] Orchiectomy or DES or both were the standard initial treatment for symptomatic advanced prostate cancer for over 40 years, until the GnRH agonistleuprolide was found to have efficacy similar to DES without estrogenic effects and was approved in 1985.

From the 1940s until the late 1980s, DES was FDA-approved as estrogen-replacement therapy for estrogen deficiency states such as ovarian dysgenesis, premature ovarian failure, and after oophorectomy.
