Hypoprolactinemia is a medical condition characterized by a deficiency in the serum levels of the hypothalamic-pituitary hormone prolactin.[1][2]
Causes
Hypoprolactinemia can result from autoimmune disease,[2] hypopituitarism,[1] growth hormone deficiency,[2] hypothyroidism,[2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D2 receptor, such as direct D2 receptor agonists like bromocriptine and pergolide, and indirect D2 receptor activators like amphetamines (through the induction of dopamine release).[3]
Diagnosis
Guidelines for diagnosing hypoprolactinemia are defined as prolactin levels below 3 µg/L in women,[4][5] and 5 µg/L in men.[6][7][8]
Symptoms
Hypoprolactinemia is associated with ovarian dysfunction in women,[4][5] and metabolic syndrome,[9] anxiety symptoms,[9] arteriogenic erectile dysfunction,[10] premature ejaculation,[6] oligozoospermia (low concentration of sperm in semen), asthenospermia (reduced sperm motility), hypofunction of seminal vesicles, and hypoandrogenism in men.[7] In one study, normal sperm characteristics were restored when prolactin levels were brought up to normal values in men with hypoprolactinemia.[8]
Hypoprolactinemia can be a cause of lactation failure after childbirth.[1][11][12]
