Prolactin deficiency is characterized by the inability of pituitary lactotrophs to secrete prolactin and by the resulting lack of puerperal lactogenesis. Other pathophysiologic mechanisms have not been fully established. Prolactin is principally regulated by tonic inhibition rather than by intermittent stimulation.

Prolactin promotes the growth of mammary alveoli, which are the components of the mammary gland, where the actual production of milk occurs.

Studies have shown that an increased level of prolactin in women who are not pregnant or breastfeeding can reduce the metabolism of fat which can result in weight gain.
Does high prolactin cause memory loss?
Memory impairments are frequently reported with hyperprolactinemia including decline in short-term memory, verbal or non-verbal memory (4, 21). Consistently, we found that patients with prolactinomas showed a sharply decreased GMV in left hippocampus that was correlated to verbal memory deficits.
