Hyperprolactinaemia: its physiology and investigation

S J Judd, L Lazarus, P Compton

    The Medical Journal of Australia
    |July 3, 1976
    PubMed
    Summary

    Elevated serum prolactin levels are common in unexplained amenorrhea. Lowering prolactin normalizes menstrual cycles and fertility, and a new method helps pinpoint the cause of hyperprolactinemia.

    Area of Science:

    • Endocrinology
    • Reproductive Medicine

    Background:

    • Radioimmunoassay advancements have improved understanding of prolactin physiology and its role in disease.
    • Hyperprolactinemia is a frequent finding across various medical conditions.

    Purpose of the Study:

    • To outline the control mechanisms of prolactin secretion.
    • To discuss the pathophysiology of secondary amenorrhea.
    • To introduce a novel method for investigating hyperprolactinemia.

    Main Methods:

    • Review of prolactin secretion control and amenorrhea mechanisms.
    • Proposal of a new diagnostic method for hyperprolactinemia.

    Main Results:

    • Elevated serum prolactin is observed in up to 20% of women with unexplained secondary amenorrhea.
    • Normalization of prolactin levels, through tumor removal or bromoergocryptine treatment, restores menstrual function and fertility.

    Conclusions:

    • Hyperprolactinemia is a significant factor in secondary amenorrhea.
    • Effective treatments exist for hyperprolactinemia, leading to restored reproductive function.
    • The proposed investigation method aids in localizing the source of elevated prolactin levels.
