Pronunciation: /əˈbɔːtəs/ · Part of speech: noun · Field: obstetrics / pathology
Definition. An abortus is a fetus that is expelled from the uterus during an abortion or miscarriage. The term refers to the products of a pregnancy that ends before the fetus is fully developed — that is, to the expelled fetus itself.
How the term is used. Abortus is a clinical and technical term, used mainly in medical, pathological, and laboratory contexts rather than in everyday speech. It may be used when the expelled tissue is examined to help understand why a pregnancy ended — for example, to investigate the cause of a miscarriage or a recurrent pregnancy loss. In some classifications the word is also used loosely to refer to the event or to a fetus expelled below a defined weight or gestational threshold.
Related contexts. The word appears in a few specific settings:
- Pathological examination — the abortus may be sent for study to look for chromosomal abnormalities, infection, or structural problems that could explain the loss.
- Microbiology — the species name Brucella abortus uses the same Latin root, because this bacterium causes contagious abortion (loss of pregnancy) in cattle and is one cause of brucellosis in humans. This is a separate usage but shares the underlying meaning of “miscarriage.”
Clinical relevance. Examining an abortus can provide valuable information after a pregnancy loss. Identifying a chromosomal or structural cause may help explain why the loss occurred, guide counselling, and inform the management of future pregnancies. Such investigation is carried out sensitively and with appropriate consent, recognising that pregnancy loss is often a distressing experience.
Distinction from related terms. Abortion names the event or procedure; to abort is the verb; an abortifacient is an agent that provokes an abortion. Products of conception is a broader clinical term covering all the tissue from a pregnancy (including the placenta and membranes), whereas abortus refers specifically to the expelled fetus.
Etymology. From Latin abortus, the past participle of aboriri, “to miscarry” or “to fail to be born” (ab- = away, amiss + oriri = to arise, to be born) — literally, “that which has miscarried.”
