Montgomery tubercles (Areolar glands), nature’s breastfeeding ointment.

Montgomery tubercles also called Areolar glands are Nature’s breastfeeding ointment. These slightly bumpy parts on the areola may become noticeable during pregnancy. The size and amount of Montgomery tubercles a lactating person may have vary, about 2 - 28 per nipple. They produce an oil that lubricates which can help prevent chafing. The antibacterial properties help keep germs away from the breasts.
