This video shows Dr. Byron Calhoun, a board certified obgyn, examining the bodies of two babies aborted by a medically induced labor with prostaglandin in the second trimester.
If the babies are bruised all over their bodies by contractions, try to imagine how painful those contractions must be for the mother. Normal labor is extremely painful and the contractions are far less severe. This is an excruciatingly painful method of abortion for both the mother and baby which can take hours to accomplish.
You can see the grimace of pain on the face of the second, 18-20 week old baby.
There is one other way abortions are done in the second trimester, the D&E.
