Vagina
part of the female genital tract
The vagina (pl.: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract through which mammals copulate and give birth. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.
During sexual intercourse, the vaginal walls produce vaginal lubrication and create friction which stimulates the penis toward ejaculation, enabling fertilization. Along with pleasure and bonding, sexual activity can cause sexually transmitted infections (STIs), which can be prevented by safe sex practices. Other health issues may also affect the human vagina.
The vagina has evoked strong reactions in societies throughout history, including negative perceptions and language, cultural taboos, and their use as symbols for female sexuality, spirituality, or regeneration of life. In common speech, the word "vagina" is often used incorrectly to refer to the vulva or to the female genitals in general.
Etymology and definition
The term vagina is from Latin vāgīna, meaning "sheath" or "scabbard".
This brief starts where responsible research should: with the source description of “Vagina” as part of the female genital tract. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as part of the female genital tract. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q5880. The Library of Congress control number is sh85141754. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
