Translation guide
The English word 'ejaculation' has two distinct meanings: the physiological act of ejecting semen, and a dated or literary term for a sudden exclamation. This guide covers both, with a focus on natural Japanese expressions.
To refer to the act of ejaculating semen, in medical, formal, or everyday contexts.
The standard medical and formal term for ejaculation. Can be used as a noun or combined with する to form a verb.
射精は男性の生殖機能の一部です。
Ejaculation is part of the male reproductive function.
To refer to a sudden, brief exclamation or interjection, often expressing emotion.
The English word 'ejaculation' in the sense of 'exclamation' is now rare and often sounds archaic or humorous. In Japanese, there is no single equivalent that carries the same nuance. Use context-appropriate words like 叫び声 or 感嘆の声 instead of trying to translate directly.
