    Summary

    Researchers identified L-fucose in human semen using gas-liquid chromatography. This method allows for the quantification of fucose in semen samples, aiding in diagnostic analysis.

    Area of Science:

    • Reproductive biology
    • Analytical chemistry

    Background:

    • Human semen contains various carbohydrates, including fructose, galactose, glucose, sorbitol, and inositol.
    • The presence of L-fucose in semen has not been extensively studied.

    Purpose of the Study:

    • To develop and validate a method for identifying and quantifying L-fucose in human semen.
    • To assess the feasibility of using L-fucose as a potential biomarker in semen analysis.

    Main Methods:

    • Human semen samples were hydrolyzed to remove interfering substances like hexosamines, amines, and amino acids.
    • Carbohydrates were derivatized into trimethylsilyl derivatives for enhanced volatility.
    • Gas-liquid chromatography was employed for the separation and identification of these derivatives.

    Main Results:

    • The developed method successfully identified L-fucose in freeze-dried human semen samples.
    • The fucose content could be determined in samples from individuals with different diagnoses.

    Conclusions:

    • Gas-liquid chromatography provides a reliable method for detecting L-fucose in human semen.
    • Quantification of L-fucose may offer new insights into semen composition and potential diagnostic applications.
