Prolactin in seminal fluid.

M L Smith, W A Luqman

    Archives of Andrology
    |September 1, 1982

    Summary
    This summary is machine-generated.

    Prolactin influences male fertility by affecting reproductive organs and sperm function. Seminal fluid prolactin levels are inconsistent in studies due to varied methods and patient groups.

    Area of Science:

    • Reproductive Endocrinology
    • Andrology
    • Biochemistry

    Background:

    • Prolactin plays a role in male reproductive functions, including hormone regulation in testes and accessory organs.
    • It facilitates sperm capacitation, a critical process for fertilization.
    • Immunoreactive prolactin (iPRL) from blood is transported to semen via accessory sex organs over several days.

    Purpose of the Study:

    • To review the role of prolactin in male reproduction.
    • To discuss the transport and characteristics of prolactin in seminal fluid.
    • To identify reasons for inconsistencies in clinical studies on seminal prolactin.

    Main Methods:

    • Literature review of existing clinical studies and biochemical data.
    • Analysis of prolactin transport mechanisms from blood to semen.

    Related Experiment Videos

  • Examination of seminal prolactin heterogeneity and its association with spermatozoa.

    • Main Results:

    • Immunoreactive prolactin (iPRL) is present in semen, with a portion potentially bound to spermatozoa.
    • Seminal iPRL exhibits heterogeneity in size.
    • Clinical data on seminal prolactin levels in fertile and infertile men are inconsistent.

    Conclusions:

    • Variability in patient populations, prolactin assays, and sample processing contribute to inconsistent clinical findings.
    • Further standardized research is needed to clarify the precise role of seminal prolactin in male fertility.
