Carnitine in seminal fluid as parameter for the epididymal function.

U Wetterauer, H J Heite

    Andrologia
    |May 1, 1978

    Summary

    Epididymis is the primary source of seminal fluid carnitine, crucial for male fertility. Carnitine levels aid in diagnosing male reproductive tract issues and conditions like azoospermia and Klinefelter's Syndrome.

    Area of Science:

    • Reproductive Biology
    • Andrology
    • Biochemistry

    Background:

    • Carnitine is a key secretion from the epididymis into human seminal fluid.
    • Over 94% of free carnitine in semen originates from the epididymis.

    Purpose of the Study:

    • To investigate carnitine concentration in patients with normal and abnormal spermiograms.
    • To explore the clinical significance of carnitine determination in andrological conditions.
    • To diagnose blockages in the male reproductive tract using carnitine levels.

    Main Methods:

    • Analysis of carnitine concentration in seminal fluid.
    • Correlation of carnitine levels with standard semen parameters.
    • Evaluation of split ejaculates.
    • Simultaneous determination of fructose, citrate, and carnitine.

    Main Results:

    • Carnitine concentration frequency distributions were analyzed for normal and azoospermic patients.
    • Clinical significance demonstrated in postvasectomy semen and Klinefelter's Syndrome.
    • Diagnosis of high blockages in the male reproductive tract was achieved.
    • Split ejaculate evaluation confirmed carnitine's origin from the ductus deferens, not seminal vesicles.

    Conclusions:

    • Carnitine determination is clinically significant in andrology, particularly for diagnosing reproductive tract obstructions.
    • Epididymis is the exclusive source of seminal fluid carnitine.
    • Carnitine levels serve as a valuable biomarker in male reproductive health assessments.
