Reproductive parameters in prolactinaemic men.

A Rocco, P Falaschi, P Pompei

    Archives of Andrology
    |May 1, 1983
    PubMed
    Summary

    Hyperprolactinaemia consistently reduces seminal volume and causes impotence, though it doesn't clearly affect sperm production. The exact cause of impotence in these conditions requires further investigation.

    Area of Science:

    • Endocrinology
    • Reproductive Medicine
    • Neuroendocrinology

    Background:

    • Hyperprolactinaemia, elevated prolactin levels, is associated with reproductive dysfunction.
    • Understanding the impact of hyperprolactinaemia on male sexual health is crucial.

    Purpose of the Study:

    • To investigate the effects of hyperprolactinaemia on sexual behavior, the hypothalamic-pituitary-testicular axis, and seminal fluid parameters.
    • To explore the relationship between hyperprolactinaemia and impotence.

    Main Methods:

    • Studied three models of hyperprolactinaemia: pituitary adenomas, metoclopramide administration, and neuroleptic therapy.
    • Assessed sexual behavior, hormonal profiles, and seminal fluid parameters.

    Main Results:

    • Hyperprolactinaemia consistently reduced seminal volume.
    • Impotence was a constant finding in hyperprolactinaemic syndromes.
    • No clear evidence linked hyperprolactinaemia to altered spermatogenesis.
    • Mildly impaired Leydig cell androgen production did not fully explain the impotence.

    Conclusions:

    • Hyperprolactinaemia significantly impacts male reproductive health, primarily affecting seminal volume and causing impotence.
    • The pathogenesis of impotence in hyperprolactinaemia is complex and likely multifactorial, not solely explained by reduced androgen production.
