Chemical abortion
A chemical abortion is a type of abortion in which a drug is used to induce the abortion, rather than a surgical procedure. Chemical abortions occur after the embryo has implanted itself in the uterus. The implantation in the uterus is when a fertilized egg becoms a pregnancy. The most common drug, called RU-486, blocks progesterone, which is a hormone required for a pregnancy to continue. Administered correctly, it has a high rate of success. Advocates of chemical abortion claim that it is easier emotionally for the women and that it is safe. However, some critics believe that chemical abortions are unsafe, and might even cause death. While available in most European countries, chemical abortion has met great controversy in Canada and the United States.This article is a stub. You can help Wikipedia by expanding it.
