Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation, and nursing. Prolactin is secreted in a pulsatile fashion in between these events.Prolactin also plays an essential role in metabolism, regulation of the immune system, and pancreatic development.rolactin provides the body with sexual gratification after sexual acts: The hormone counteracts the effect of dopamine, which is responsible for sexual arousal. This is thought to cause the sexual refractory period. The amount of prolactin can be an indicator for the amount of sexual satisfaction and relaxation.
Prolactin is a hormone. A hormone is a chemical substance, which is secreted by an endocrine gland, and is transported to another part of the body (the target tissue) where it has an effect.Hormones act at the target tissue by binding to a receptor site on the responding cells.rolactin is secreted periodically by the pituitary throughout the day and night. The secretion of prolactin is increased by a number of external stimuli including stress, breast-feeding and sexual activity. In women, the breast is the predominant prolactin target tissue.
