The labia minora (singular: labium minus) or nymphae are two longitudinal cutaneous folds on the human vulva. They are situated between the labia majora, and extend from the clitoris obliquely downward, laterally, and backward on either side of the vulval vestibule, ending between bottom of the vulval vestibule and the labia majora. In the virgin the posterior ends of the labia minora are usually joined across the middle line by a fold of skin, named the frenulum labiorum pudendi or fourchette. Labia minora may vary widely in size from woman to woman.
On the front, each labium minus (nympha) divides into two portions: the upper division passes above the clitoris to meet the labium minus of the opposite side—which may not be equal in size—forming a fold which overhangs the glans clitoridis; this fold is named the preputium clitoridis. The lower division passes beneath the glans clitoridis and becomes united to its under surface, forming, with the labium minus of the opposite side—which also may not be equal in size—the frenulum clitoridis.
On the opposed surfaces of the labia minora are numerous sebaceous follicles.
