noun
Anatomical term; used in medical, biological, and formal contexts. In everyday conversation, euphemisms or more colloquial terms are often preferred.
膣の健康は女性にとって重要です。
Vaginal health is important for women.
医師が膣の検査を行った。
The doctor performed a vaginal examination.
The kanji 膣 is a kokuji (Japanese-made kanji) composed of the flesh radical 肉 (⺼) and 窒, which provides the phonetic element. The exact derivation is uncertain, but the character was created to represent the anatomical term.
