The labia majora are two large, fatty folds of skin which extend down from a woman’s mons pubis to her perineum. This Latin word translates to "main lips." The tissue that forms the labia majora is the same as that which forms the male scrotum.
The labia majora are the most visible parts of a woman’s vulva. Along with the labia minora, the labia majora works to surround and protect a woman’s clitoris, vagina, and urethra. The outsides of the labia majora become covered with strong hairs after the onset of puberty, while the insides are smooth, hairless, and covered with a mucous membrane.
The singular form of labia majora is labium majus. The labia majora are commonly called the outer labia or outer lips.
