Abortion is the termination of a pregnancy after implantation.
Surgical abortions are done by placing an instrument into the uterine cavity and applying suction. This procedure is called vacuum aspiration. It blocks the effect of progesterone on the lining of the uterus. It is followed by taking a prostaglandin called misoprostol in 48 hours later. This type of abortion may be done in the office of any clinician without surgery.
