Vitamin A in human semen

N Virji, A Vahlquist, R Eliasson

    Experientia
    |December 15, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Human semen contains vitamin A, measured using fluorometry and HPLC. Its concentration in human sperm is lower than in rabbits but similar to bulls.

    Area of Science:

    • Reproductive biology
    • Nutritional science
    • Analytical chemistry

    Background:

    • Vitamin A is essential for various physiological processes.
    • Spermatozoa are specialized cells crucial for reproduction.
    • Understanding nutrient composition in semen is important for reproductive health.

    Purpose of the Study:

    • To quantify vitamin A concentration in human semen.
    • To compare vitamin A levels with and without hydrolysis.
    • To establish reference values for human spermatozoa.

    Main Methods:

    • Analysis of human semen samples.
    • Quantification of vitamin A using fluorometry.
    • Confirmation of vitamin A levels via high-performance liquid chromatography (HPLC).

    Main Results:

    • Vitamin A was detected in human semen.
    • Hydrolysis did not significantly alter vitamin A measurements.
    • Human spermatozoa vitamin A levels are lower than rabbit spermatozoa but comparable to bull spermatozoa.

    Conclusions:

    • Human semen contains measurable levels of vitamin A.
    • HPLC and fluorometry are suitable methods for vitamin A determination in semen.
    • Comparative analysis suggests species-specific variations in spermatozoal vitamin A content.
