Selenium in bovine spermatozoa

S M Niemi, F B Kuzan, P L Senger

    Journal of Dairy Science
    |May 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Selenium binds to proteins in bull sperm, with over 75% released by dithiothreitol. This bound selenium is primarily located in a specific protein of about 21,500 daltons.

    Area of Science:

    • Reproductive biology
    • Biochemistry
    • Trace element research

    Background:

    • Selenium is an essential trace element with known roles in male reproductive health.
    • Understanding selenium's interaction with sperm components is crucial for assessing its impact on fertility.

    Purpose of the Study:

    • To investigate the association of selenium with ejaculated bovine spermatozoa.
    • To identify the specific spermatozoal components that bind selenium.

    Main Methods:

    • Incubation of ejaculated bovine spermatozoa with radioactive selenium-75.
    • Treatment with dithiothreitol to release bound selenium.
    • Polyacrylamide gel electrophoresis to analyze protein fractions.

    Main Results:

    Related Experiment Videos

    • Over 75% of radioactive selenium-75 was released from spermatozoa after incubation with dithiothreitol.
    • Of the released selenium-75, 85% was associated with spermatozoal protein.
    • Selenium-75 was predominantly found in a single protein band with an approximate molecular weight of 21,500 daltons.

    Conclusions:

    • Selenium binds to a specific protein in ejaculated bovine spermatozoa.
    • This protein, with a molecular weight of approximately 21,500 daltons, appears to be a primary site of selenium association in sperm.
