:Absolutely agree that the topic of this page is induced abortion, rather than miscarriage, so how about "Abortion is the termination of pregnancy by the induced removal or expulsion from the uterus of a fetus or embryo, not resulting in a live birth".  This has the dual benefit of clarifying the pre-viability piece, and clarifying that the article is about deliverate intervention.  Other words could be used instead of 'induced', including 'deliberate', 'medical or surgical', or 'intentional'.  Thoughts?
