Prolactin: what is this hormone for?

Prolactin is involved in the process of lactation. It is a hormone released by a small gland located at the base of the brain (the pituitary gland) and normally secreted after delivery.

Its secretion is due to the abrupt drop of estrogen and progesterone following the disappearance of the placenta during delivery.

In some cases, outside of pregnancy, abnormal secretion of prolactin may occur.

For baby breastfeeding

What is his role ?
The process of lactation begins during pregnancy, but it is of course especially after the birth of the baby, that the prolactin level increases and then causes the rise of milk in the mother.

Specifically, this hormone triggers milk production at the alveoli of the breast when the baby heads.

The more the baby suckles, the more the mother will produce prolactin. Prolactin levels are also higher at night, allowing nighttime feedings.

Note that lactation is dependent on another hormone: the oxytocyne.

Outside any pregnancy context, abnormal secretion of prolactin may have different origins.

Breastfeeding Tip: Give breast as often as baby claims! In fact, the more frequent feedings, the higher your prolactin level will remain. Milk will be manufactured regularly!

When does prolactin decrease?

The amplitude of the prolactin secretion peaks decreases with time. Whether the mother is breastfeeding or not, the hormone begins to decrease around the 15th day after the baby is born, and normalizes in 4 to 6 weeks.
