The term 'vasectomy' is a modern medical compound, first recorded in English in the late 19th century. It is constructed from the Latin root vas- (vessel, duct), specifically referring to the vas deferens, and the Greek-derived suffix -ectomy (surgical excision). The literal meaning, "cutting out of the duct," describes the procedure's core action of severing or removing a section of the sperm-carrying tube. This combination of classical roots follows a standard pattern in medical terminology, where Latin provides the anatomical reference and Greek provides the procedural action, creating a precise, technical term for a targeted surgical intervention.

Structure: vas (vessel, duct) + ectomy (surgical removal) - vas: From Latin vas meaning "vessel" or "duct". In this word, it refers specifically to the vas deferens, the duct that conveys sperm. - ectomy: From Greek ektomē meaning "a cutting out", derived from ek- (out) + temnein (to cut). It is a combining form denoting a surgical removal procedure.
