Circulating prolactin levels. I. Normal females.

A N Poindexter, V C Buttram, P K Besch

    International Journal of Fertility
    |January 1, 1977
    PubMed
    Summary

    This study measured circulating prolactin levels in females across different life stages. Prolactin levels change dynamically throughout life, suggesting a significant role in human physiology similar to animals.

    Area of Science:

    • Endocrinology
    • Reproductive Biology

    Background:

    • Prolactin is a hormone with diverse physiological roles.
    • Its function in human reproductive stages requires further elucidation.

    Purpose of the Study:

    • To quantify circulating prolactin levels in females across various life stages.
    • To explore potential parallels between human and animal prolactin functions.

    Main Methods:

    • Utilized a specific, homologous radioimmunoassay technique.
    • Quantitated prolactin levels in distinct female age groups: newborns to peripubertal, reproductive, gravid/puerperal, and postmenopausal.

    Main Results:

    • Demonstrated dynamic changes in prolactin levels throughout female lifespan.
    • Observed patterns suggest prolactin's role in humans may mirror that in animals.

    Conclusions:

    • Circulating prolactin exhibits significant variation across female life stages.
    • Further molecular-level investigation is needed to clarify prolactin's role in the ovarian cycle.
