David Daleiden and Jon A. Shields on why so many abortion workers have turned pro-life :
In the aftermath of Roe v. Wade, second-trimester abortions were usually performed by saline injection. The doctor simply replaced the amniotic fluid in the patients uterus with a saline solution and induced labor, leaving it to nurses to dispose of the expelled fetus. That changed in the late 1970s, when dilation and evacuation (D&E) emerged as a safer method. Today D&E is the most common second-trimester procedure. It has been performed millions of times in the United States.
But although D&E is better for the patient, it brings emotional distress for the abortionist, who, after inserting laminaria that cause the cervix to dilate, must dismember and remove the fetus with forceps. One early study, by abortionists Warren Hern and Billie Corrigan, found that although all of their staff members approved of second trimester abortion in principle, there were few positive comments about D&E itself. Reactions included shock, dismay, amazement, disgust, fear, and sadness. A more ambitious study published the following year, in the September 1979 issue of the American Journal of Obstetrics and Gynecology, confirmed Hern and Corrigans findings. It found strong emotional reactions during or following the procedures and occasional disquieting dreams.
