This book tells a story about women who attained legendary status in the annals of medicine. They were exposed prenatally to what was promoted as a benign and exciting new wonder drug prescribed to millions of American women to prevent miscarriage from the 1940s to the 1970s. This new reproductive technology—the synthetic estrogen DES — proved to be ineffective in preventing miscarriage, and in the long run it has had profound and damaging consequences for children, especially daughters of the women for whom it was prescribed (Dieckmann et al. 1953; Giusti, Iwamoto, and Hatch 1995)
