They are continually monitored by our internal peer-review process and if we see anyone making material science errors, we don't let them write for us again. Dopamine is the primary Prolactin Inhibiting Factor (PIF) and the most important regulator of its secretion. Prolactin causes breasts to grow and develop and causes milk to be made after a baby is born. Other hormones essential for this process include insulin and oxytocin [4, 35].

Prolactin (PRL) is a peptide hormone encoded by the PRL gene. Women — When a high blood prolactin concentration interferes with the function of the ovaries in a premenopausal woman, secretion of estradiol (the main female sex hormone [estrogen] in women) decreases. Prolactinoma treatment consists of two main . Prolactin is made by the pituitary gland, a pea-sized organ found at the base of the brain. Prolactin levels may be elevated for any number of reasons.
