abortion definition

The deliberate termination of a pregnancy, usually before the embryo or fetus is capable of independent life. In medical contexts, this procedure is called an induced abortion and is distinguished from a spontaneous abortion (miscarriage) or stillbirth.

Note: Abortion laws are extremely controversial. Those who describe themselves as “pro-choice” believe that the decision to have an abortion should be left to the mother. In contrast, the “pro-life” faction, arguing that abortion is killing, holds that the state should prohibit abortion in most cases. Feminists (see feminism) and liberals generally support the pro-choice side; Roman Catholics and Protestant fundamentalists generally back the pro-life side. (See Roe versus Wade.)

abortion definition

The ending of pregnancy and expulsion of the embryo or fetus, generally before the embryo or fetus is capable of surviving on its own. Abortion may be brought on intentionally by artificial means (induced abortion) or may occur naturally (spontaneous abortion, which is commonly referred to as a miscarriage). (Compare stillbirth; see also family planning and population control.)

spontaneous abortion definition

A miscarriage or stillbirth. (See abortion.)
