Medical Definition of Abortion
Abortion: In medicine, an abortion is the premature exit of the products of conception (the fetus, fetal membranes, and placenta) from the uterus. It is the loss of a pregnancy and does not refer to why that pregnancy was lost.
A spontaneous abortion is the same as a miscarriage. The miscarriage of three or more consecutive pregnancies is termed habitual abortion or recurrent pregnancy loss.Source: MedTerms™ Medical Dictionary
