Prolactin - PERLA Health


Prolactin is a hormone that is most well known for its role in lactation (the secretion of breast milk). It is mainly produced by the pituitary gland in the brain, but can also be produced by other tissues. Prolactin is an important hormone in the body of men and women, as it also can impact behavior, the metabolism, the immune system and many fluids in the body.
