Collectively, these parts are called the vulva. Rich with nerves, the vulva can provide sexual pleasure when properly stimulated. The vagina is a muscular tube about three to four inches long that ends the birth canal. The vaginal opening is visible from the outside but it is protected by the labia when a woman stands and during most activities. The labia majora are two folds of skin that extend from the front of the vaginal opening to the back of it.

Ambiguous genitalia is a rare condition in which an infant's external genitals don't appear to be clearly either male or female. In a baby with ambiguous genitalia, the genitals may be incompletely developed or the baby may have characteristics of both sexes. The external sex organs may not match the internal sex organs or genetic sex.
The external genital organs include the mons pubis, labia majora, labia minora, Bartholin glands, and clitoris. The area containing these organs is called the vulva. Protecting the internal genital organs from infectious organisms.
