Uterin

Uterin is an adjective denoting a relationship to the uterus. In contemporary English, the preferred form is uterine; uterin appears chiefly as an older or variant spelling. You may encounter uterin in historical texts or in transliterations that aim to preserve earlier usage. Most modern medical writing uses uterine when describing the uterus, its parts (such as the uterine cavity or uterine arteries), or conditions and procedures involving the uterus.

Etymology: Uterin derives from the Latin uterus, with the English suffix -in/-ine used to form adjectives meaning “pertaining to.” Over time, the form uterine became standard, while uterin fell into disuse in everyday medical language.

Usage notes: In current nomenclature, uterine is the recommended form. Uterin may still be encountered in older literature or in contexts aiming to reproduce historical spellings; it is generally considered archaic or nonstandard in modern clinical prose.
