Hormone secretion can be stimulated and inhibited by: 1  Other hormones (stimulating- or releasing -hormones) 2  Plasma concentrations of ions or nutrients, as well as binding globulins. 3  Neurons and mental activity.  Environmental changes, e.g., of light or temperature.
In addition to tonic inhibition by dopamine, prolactin secretion is positively regulated by several hormones, including thyroid-releasing hormone, gonadotropin-releasing hormone and vasoactive intestinal polypeptide. Stimulation of the nipples and mammary gland, as occurs during nursing, leads to prolactin release.n contrast to what is seen with all the other pituitary hormones, the hypothalamus tonically suppresses prolactin secretion from the pituitary. In other words, there is usually a hypothalamic brake set on the lactotroph, and prolactin is secreted only when the brake is released.
