An abortion is the termination of a pregnancy by the removal or expulsion of an embryo or fetus from the uterus, resulting in or caused by its death. An abortion can occur spontaneously due to complications during pregnancy or can be induced. Abortion as a term most commonly refers to the induced abortion of a human pregnancy, while spontaneous abortions are usually termed miscarriages.
Abortion has a long history and has been induced by various methods including herbal abortifacients, the use of sharpened tools, physical trauma and other traditional methods. Modern medicine utilizes medications and surgical procedures to induce abortion. The legality, prevalence, and cultural views on abortion vary substantially around the world. In many parts of the world there is a divisive public debate over the ethical and legal aspects of abortion between the pro-life and pro-choice movements. The approximate number of induced abortions performed worldwide in 2003 was 42 million, which declined from nearly 46 million in 1995.
