Glands of Montgomery

These glands play a crucial role in lactation and breast health.

Glands of Montgomery are specialized sebaceous glands located within the areola of the breast. These small bumps, often visible on the surface of the areola, are responsible for secreting an oily substance. This secretion helps to lubricate the nipple during breastfeeding and protects against bacterial infections.

Function

The primary function of the Glands of Montgomery is to secrete a lubricant that supports the breastfeeding process. During lactation, their secretion aids in keeping the nipple moisturized and preventing cracking, which can be painful and detrimental to mothers who are nursing. Additionally, the oily secretion contains antibacterial properties, which helps protect both the nipple and the areola from infections that could pose risks to both mother and infant. The presence of these glands is also thought to provide a sensory cue to infants, assisting them in locating the nipple when breastfeeding. Overall, they play a vital role in sustaining lactation and promoting maternal-infant bonding through successful feeding experiences.

Location

The Glands of Montgomery are located in the areola, the pigmented area surrounding the nipple. They are situated just beneath the surface of the skin, and a typical breast may contain anywhere from 10 to 20 of these glands. Their positioning allows them to discharge their secretions directly onto the nipple, particularly during breastfeeding. The areola itself varies in size and color among individuals, which can influence the visibility of the glands. They tend to become more prominent during pregnancy and lactation, emphasizing their functional importance during these times.

Did You Know?

Glands of Montgomery can become more noticeable or pronounced during pregnancy as hormones stimulate their activity.
The secretion from these glands not only lubricates the nipple but also contains antimicrobial properties that can help prevent infections.
These glands may also play a role in pheromone secretion, which could have implications for mother-infant bonding.
