What is Prolactin?
Prolactin is a hormone named originally after its function to promote milk production (lactation) in mammals in response to the suckling of young after birth.
How does prolactin affect the body?
It has since been shown to have more than 300 functions in the body. These can be divided into a number of areas:
- Regulation of fluids (osmoregulation)
- Regulation of the immune system (immunoregulation)
- Behavioral functions.
Prolactin’s role in lactation and breastfeeding
After delivery of your baby, progesterone levels drop, which increases the number of prolactin receptors on the mammary alveolar cells.
This allows for milk secretion through your nipple, commonly known as lactation.
What does prolactin do for the body?
Prolactin stimulates breast development and milk production in women. There is no known normal function for prolactin in men.
In humans, prolactin is produced both in the front portion of the pituitary gland (anterior pituitary gland) and in a range of sites elsewhere in the body.
Lactotroph cells in the pituitary gland produce prolactin, where it is stored and then released into the bloodstream.
Human prolactin is also produced in the uterus, immune cells, brain, breasts, prostate, skin and adipose tissue.
