D.E.S.: An Uncertain Legacy VHS 55 mins. From 1941 to 1971, several million pregnant women were given D.E.S., a synthetic estrogen prescribed to prevent miscarriages. Today, cancer and other medical problems are appearing in some of the children of women who took the drug. This documentary focusses on a young D.E.S. daughter who has cancer and who, with her mother, founded the first D.E.S. action group in Canada to alert the public to the drug's potential health hazards. The film puts the whole phenomenon of prescription drugs and women into historical perspective, and raises the issues of commer- cialism and sexism in the medical and health-care system. To-day, although it is banned for use during pregnancy, D.E.S. and D.E.S.-type drugs are still used in estrogen-replacement therapy, in the morning after pill, as a fertility drug, and as a lactation suppressant for new mothers.
