What is the physiology of milk production?

What is the physiology of milk production?

The breast is composed of 4 to 18 segments (lobes) embedded in fat, within each lobe are alveoli (the milk-producing cells) surrounded by myoepithelial cells which contract to send milk forward into the ductules.

-Ductules enlarge into lactiferous ducts and sinuses, where milk collects behind nipple.

-Each nipple has pores through which milk is transferred to the suckling infant.

What is Lactogenesis stage I?

Breasts start preparing for milk production around week 16 in the pregnancy. Colostrum is present.

- After birth, decrease in estrogen and progesterone levels triggers release of prolactin from anterior pituitary gland

What is Lactogenesis stage II?

-By day 3-5, the breasts begin producing mature milk, often referred to as “the milk coming in.”

• Colostrum is still present, until up to day 21.

• Prolactin produced in response to infant suckling and emptying of breasts.

• As nipple is stimulated by suckling infant, posterior pituitary prompted by hypothalamus produces oxytocin.

  -Responsible for milk-ejection reflex or let-down reflex
