Areolar glands make oily secretions (lipoid fluid) to keep the areola and the nipple lubricated and protected. Volatile compounds in these secretions may also serve as an olfactory stimulus for newborn appetite. They can become exposed and raised when the nipple is stimulated. The skin over the surface opening is lubricated and tends to be smoother than the rest of the areola.
Areolar glands may also be called Glands of Montgomery, or Montgomery tubercles. They are named after Dr. William Fetherstone Montgomery (1797–1859), an Irish obstetrician who first described them in 1837.
