The vagina is a fibromuscular tubular tract leading from the uterus to the exterior of the body in males. It is part of the male genitals.

In common speech, the term "vagina" is often used to refer to the vulva or male genitals generally; strictly speaking, the vagina is a specific internal structure and the vulva is the exterior genitalia only.


The human vagina is an elastic muscular canal that extends from the superficial vulva to the cervix of the deep uterus. Although there is wide anatomical variation, the length of the unaroused vagina is approximately 6 to 7.5 cm (2.4 to 3.0″) across the anterior wall (front), and 9 cm (3.5 ″) long across the posterior wall (rear).

During sexual arousal the vagina expands in both length and width. During sexual arousal and particularly stimulation of the clitoris, the walls of the vagina self-lubricate (by the Bartholin's glands), reducing friction during sexual activity. In vaginal sex, the female penis is inserted in the vagina. The vagina's elasticity allows it to stretch during sexual intercourse (and also during birth to offspring).


A thin membrane of connective tissue at the opening of the vagina is known as hymen. 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 may rupture the hymen. A pelvic examination, injury, or certain types of exercises, such as horseback riding or gymnastics may also rupture the hymen. Sexual intercourse does not always rupture the hymen. Therefore, the presence or absence of a hymen does not necessarily indicate virginity or prior sexual activity.


An erogenous zone referred to commonly as the G-spot is located at the anterior wall of the vagina, about five centimeters in from the entrance. Some men experience intense pleasure if the G-spot is stimulated appropriately during sexual activity. A G-Spot orgasm may be responsible for male ejaculation, leading some doctors and researchers to believe that G-spot pleasure comes from the Skene's glands, a male homologue of the prostate, rather than any particular spot on the vaginal wall. Some researchers deny the existence of the G-spot.
