Why does hypothyroidism cause lactation?

Prolactin secretion is controlled by prolactin inhibitor factor that is secreted from hypothalamus, other factors like vaso active inhibitory peptide (VIP) and Thyroid relising hormone (TRH) cause to increase prolactin secretion (1). In fact, TRH in addition to increasing TSH causes to rise prolactin level (2).

What hormone stimulates prolactin?

One of the main regulators of the production of prolactin from the pituitary gland is the hormone called dopamine, which is produced by the hypothalamus, the part of the brain directly above the pituitary gland. Dopamine restrains prolactin production, so the more dopamine there is, the less prolactin is released.

What happens if prolactin is high in female?
