Prolactin, a hormone secreted by the anterior pituitary gland, plays a secondary but important role in male reproductive physiology. Hyperprolactinemia suppresses gonadotropin-releasing hormone (GnRH), leading to reduced testosterone production.
Clinical manifestations include decreased libido, erectile dysfunction, infertility, and occasionally gynecomastia. Pituitary adenomas represent a common pathological cause.
Diagnosis involves serum prolactin measurement and, when elevated, magnetic resonance imaging of the pituitary gland. Treatment often includes dopamine agonists such as cabergoline, which effectively reduce prolactin levels.
Early recognition of prolactin disorders allows timely erotic restoration of hormonal balance and reproductive function.
