Montgomery’s tubercles are the external part of glands that make oily secretions to keep the areola and the nipple lubricated and protected. Only the portion of the gland on skin’s surface is called Montgomery’s tubercles in breastfeeding terminology. Montgomery’s tubercles become much more pronounced and raised when the nipple is stimulated. The skin over the surface openings are lubricated and tend to be smoother than the rest of the areola. During pregnancy the Montgomery’s tubercles become increasingly visible on the nipple and areola.
