Rosemary for Remembrance

I didn't know DES caused heart problems: my understanding was if given in pregnancy to prevent miscarriage that it caused a rare vaginal cancer in the daughters of women who took it and also malformations of the reproductive tract. It also had effects on sons: increased risk of testicular cancer, infertility and urogenital abnormalities in development. The women themselves were at somewhat increased probability of breast cancer. Though for wild speculation, see what was said about its effects upon gender identity in the offspring.
