This female organ plays a central role in childbirth, menstruation, and sexual intercourse.
The vagina is a muscular tube that extends from a woman's vulva, the part of her genital area on the outside of her body, to her cervix, the lower part of the uterus — the "womb" in which a fetus grows during pregnancy.
In other words, the vagina essentially connects the uterus to the outside of the body.
A woman's vaginal opening is surrounded by the hymen, a thin membrane of tissue that can tear during sexual intercourse or exercise.
In adult women, the vagina typically measures about 3 to 5 inches long. It's lined with a mucous membrane.
The lining of the vagina contains folds and wrinkles during the reproductive years. Before puberty and after menopause, this lining is smooth.
Functions of the Vagina
The vagina plays a number of different roles in a woman's body.
During vaginal sexual intercourse, a man's penis is inserted into the vagina. The vagina serves as a passageway for a man's sperm to reach a woman's egg, which can result in pregnancy.
When a woman is aroused, the vagina expands, and its walls lubricate to reduce friction. The nerve endings near the entrance of the vagina may provide pleasure during sexual activity.
The vagina also acts as the route for delivering a baby — known as the birth canal — and for the exit of menstrual blood from the body.
Conditions Affecting the Vagina
Vaginal problems can impact many aspects of a woman's health.
