    Area of Science:

    • Reproductive biology
    • Andrology
    • Clinical laboratory science

    Background:

    • The standard Friberg test is crucial for assessing sperm-male factor infertility.
    • Challenges exist in interpreting the Friberg test due to immobile sperm and debris.
    • Current methods can lead to a high percentage of uninterpretable results.

    Purpose of the Study:

    • To optimize the Friberg test for improved interpretability and diagnostic accuracy.
    • To address limitations in the standard Friberg test protocol.
    • To enhance the reliability of sperm penetration assays.

    Main Methods:

    • Reduced incubation time from four hours to two hours.
    • Modified antigen preparation by filtering motile sperm using the Kremer sperm penetration meter.
    • Compared modified test reliability against standard Friberg, Kibrick, and Franklin-Dukes tests.

    Main Results:

    • Shortening incubation to two hours improved objective interpretation to 76%.
    • Modifying antigen preparation with the sperm penetration meter allowed 80% interpretation after four hours and 100% after two hours.
    • The modified test maintained reliability comparable to established methods.

    Conclusions:

    • Optimized Friberg test protocols significantly enhance sperm analysis interpretability.
    • The modified method offers a more reliable and objective approach to male infertility assessment.
    • These improvements facilitate more accurate diagnosis in andrology.
