It is estimated that at least 2–3 million fetuses were exposed. A relationship between fetal DES exposure and clear cell carcinoma of the vagina was later discovered, and several other related anomalies have since been noted. In one-third of all exposed women, there are changes in the vagina (adenosis, septa), cervix (deformities and hypoplasia of the vaginal portion of the cervix), or uterus (T-shaped cavity) (eFigure 18–19).
