Were you pregnant or born between 1938 & 1980's

You may be affected by DES

DES is a hormone drug - a synthetic oestrogen - that was prescribed in good faith to millions of pregnant women in many countries around the world, including Australia, from 1938 to the 1980s. DES was thought to prevent miscarriage and ensure a healthy pregnancy, but it did not work.

Women who took DES and the children they carried are at risk for certain health problems and may need special care, even if there are no obvious concerns. We do not know exactly how may women in Australia are DES exposed, but we know DES was prescribed by both obstetricians and general practitioners as tablets, injections, vaginal suppositories and sometimes in pregnancy vitamins. There were over 200 brand names of this drug. There may be many people who do not know they were exposed to DES and some women may not remember taking DES.

DES was also used to stop breast-feeding after giving birth and this is not known to cause any problems. In the latter years of DES usage, another hormone called progesterone was much more commonly used in pregnancy, but this hormone is not known to cause any problems.

It is not known whether DES will affect future generations. This information about DES and its links will be maintained and updated. If you definitely know you have been exposed to DES, or if your mother said she took "hormones" whilst carrying you, or if you are merely interested in aspects of women's health, keep watching this site over the years for any further information as it comes to hand from research and clinical experience.

If you are a DES daughter there is important new information about breast cancer risks in the section about DES daughters
