The human vagina is an elastic muscular canal that extends from the cervix to the vulva.[1] Although there is wide anatomical variation the average vagina is 6 to 7 inches (15 to 18 cm) in length; its elasticity allows it to stretch during sexual intercourse and during birth to offspring.[2] [3] The vagina connects the vulva (which is outside the body) to the cervix of the uterus (which is inside the body).

If the woman stands upright, the vaginal tube points in an upward-backward direction and forms an angle of slightly more than 45 degrees with the uterus. The vaginal opening is at the back (caudal) end of the vulva, behind the opening of the urethra. Above the vagina is Mons Veneris. The vagina, along with the inside of the vulva, is reddish pink in color, as with most healthy internal mucous membranes in mammals.

Vaginal lubrication is provided by the Bartholin's glands near the vaginal opening and the cervix. The membrane of the vaginal wall also produces moisture, although it does not contain any glands. Before and during ovulation, the cervix produces cervical mucus, which provides a favorable environment for sperm to survive.

The hymen is a membrane which is situated at the opening of the vagina. As with many female animals, the hymen covers the opening of the vagina from birth until it is ruptured during activity. The hymen may rupture during sexual or non-sexual activity. Vaginal penetration with the fingers, a dildo or penis, may rupture the hymen. A pelvic examination, injury, or certain types of exercise such as horseback riding may also rupture the hymen. Sexual intercourse does not always rupture the hymen. Therefore, the presence or absence of a hymen does not indicate virginity or prior sexual activity.
