How is a prostaglandin abortion performed?
In a prostaglandin abortion, a dose of prostaglandin hormones is injected into the uterine muscle, which induces violent labor resulting in the death of the fetus. Prostaglandin abortions, typically performed in the second and early third trimester, are rarely used today, due to the relatively high chance that the fetus will survive the abortion and be born alive.
