One type of induced abortion is called a "medical abortion" or a "medication abortion". In this type of abortion, a doctor gives the woman one or two medications that will end her pregnancy. A medication abortion can only be done early on in the pregnancy. This is because the medications that are used work best when they are started as early as possible, and after a woman has been pregnant for about two months, the medications usually do not work very well. Because of this, medication abortion usually is not used after a woman has been pregnant for 9 weeks. Some of the benefits (or reasons why some women choose this type of abortion) are that it can be started as soon as a woman realizes she is pregnant; it does not require anesthesia; and the woman does not have to have a procedure in a hospital or clinic to have the fetus removed, like with the other kind of abortion that is done. After a woman is given the medication or medications that end her pregnancy, the abortion happens like a "spontaneous" abortion or a miscarriage. (The woman passes the fetus, along with the blood and tissue that have built up in the uterus, from her vagina.)
