Prolactin is a hormone produced by the pituitary gland that stimulates milk production in women. High levels of prolactin can cause symptoms such as irregular periods, infertility, and erectile dysfunction in men.

iollo markers that associate with Prolactin


Dopamine is the primary inhibitor of prolactin secretion from the anterior pituitary gland. Decreased dopamine levels or dopamine receptor antagonism leads to increased prolactin secretion.


Tyrosine is the amino acid precursor for dopamine synthesis. Changes in tyrosine availability could influence dopamine levels and consequently impact prolactin secretion.
