What key characteristic do Montgomery glands provide for infants?

Enhance milk production
Inhibit bacterial growth
Help with digestion
Regulate temperature

The correct answer is: Inhibit bacterial growth

Montgomery glands, located in the areola of the breast, are specialized sebaceous glands that secrete a lubricating substance. This secretion plays an important role in the breastfeeding process by providing a protective barrier to the nipple area, which can help inhibit bacterial growth. The secretions contain antimicrobial properties that create a less hospitable environment for pathogens, thereby reducing the risk of infections during breastfeeding. This characteristic is particularly important as it ensures that the infant can feed safely and effectively while minimizing potential health risks associated with bacteria that could be introduced during feeding. The other options do not correctly characterize the primary function of Montgomery glands. They are not directly involved in enhancing milk production, aiding digestion, or regulating temperature, which are functions of different physiological processes within the body or other anatomical structures.
