Product description:
Diethylstilbestrol (DES) is an estrogen that was first manufactured in a laboratory in 1938, so it is called a "synthetic
estrogen." During 1938-1971, U.S. physicians prescribed DES to pregnant women to prevent miscarriages and
avoid other pregnancy problems. As a result, an estimated 5-10 million pregnant women and the children born of
these pregnancies were exposed to DES. Physicians prescribed DES to pregnant women on the theory that
miscarriages and premature births occurred because some pregnant women did not produce enough estrogen
naturally. At the time, physicians thought DES was safe and would prevent miscarriages and pre-term (early)
births.
In 1953, published research showed that DES did not prevent miscarriages or premature births. However, DES
continued to be prescribed until 1971. In that year, the Food and Drug Administration (FDA) issued a Drug Bulletin
advising physicians to stop prescribing DES to pregnant women. The FDA warning was based on a study
published in 1971 that identified DES as a cause of a rare vaginal cancer in girls and young women who had been
exposed to DES before birth (in the womb).
