The labia majora extend from the mons pubis above, on either side of the vaginal introitus, to the perineal area below. The outer sides of the labia are covered with pigmented skin, sebaceous glands, and after puberty, coarse hair. The inner sides are smooth and hairless, with some sweat glands. Beneath the skin layer, there is mostly fatty tissue with some ligaments, smooth muscle fibres, nerves and blood vessels.
