    Area of Science:

    • Reproductive biology
    • Biochemistry
    • Andrology

    Background:

    • Semen analysis is crucial for assessing male fertility.
    • Lipid profiles within seminal plasma may influence sperm function.
    • Fractionation of ejaculates allows for detailed analysis of seminal components.

    Purpose of the Study:

    • To analyze the distribution of lipids, phospholipids, and cholesterol in different fractions of human ejaculates.
    • To compare lipid profiles between normal healthy volunteers and patients with Klinefelter's syndrome.
    • To investigate the potential relationship between seminal lipid composition and sperm parameters.

    Main Methods:

    • Ejaculates were split into fractions.
    • Lipid, phospholipid, and cholesterol concentrations were quantified in each fraction.
    • Cholesterol-phospholipid and free-ester cholesterol ratios were calculated.
    • Samples from normal volunteers and Klinefelter's syndrome patients were analyzed.

    Main Results:

    • Fraction I of normal ejaculates showed higher total lipids, phospholipids, and cholesterol.
    • Fraction III of normal ejaculates had higher glyceride concentrations.
    • Significant variations in cholesterol-phospholipid and free-ester cholesterol ratios were observed across fractions.
    • Patients with Klinefelter's syndrome exhibited higher glyceride and lower phospholipid concentrations compared to controls.

    Conclusions:

    • Seminal lipid composition varies significantly between ejaculate fractions in healthy men.
    • These variations may have implications for sperm survival and motility.
    • Klinefelter's syndrome is associated with distinct alterations in seminal glyceride and phospholipid levels.
