What is the Origin of Prolactin Balance?

The term is derived from endocrinology, relating to the hormone prolactin, which literally means "for milk production," reflecting its primary role in mammalian reproduction. The concept of "Balance" emphasizes the need for a tightly controlled concentration, as both deficiency and excess can be pathological and disrupt systemic homeostasis. Clinical attention focuses heavily on preventing and managing hyperprolactinemia due to its systemic impact.

What is the Mechanism of Prolactin Balance?

Prolactin secretion from the anterior pituitary is primarily under inhibitory control by dopamine from the hypothalamus, which acts as Prolactin-Inhibiting Hormone (PIH). When dopamine inhibition is reduced, or in the presence of a prolactin-secreting tumor, prolactin levels rise. High prolactin then centrally inhibits GnRH pulsatility, disrupting the production of sex hormones like testosterone and estrogen, thereby impacting reproductive and metabolic health.

Prolactin Balance

Meaning

Prolactin balance refers to the maintenance of circulating prolactin hormone levels within the optimal physiological range for a given individual and context. While primarily known for its role in lactation, prolactin also influences reproductive function, metabolism, and immune response in both sexes. Imbalance, specifically hyperprolactinemia, can suppress the Hypothalamic-Pituitary-Gonadal (HPG) axis, leading to hypogonadism and associated symptoms of hormonal deficiency.
