    Summary

    Biologically oriented sperm function tests are reviewed. Hamster oocyte penetration tests, especially with A 23187, show promise in diagnosing male infertility and guiding treatment strategies.

    Area of Science:

    • Reproductive Biology
    • Andrology
    • Clinical Diagnostics

    Background:

    • Sperm function tests are crucial for evaluating male fertility.
    • Existing tests for sperm motility and fertilizing capacity have limitations.

    Purpose of the Study:

    • To critically evaluate biologically oriented human sperm function tests.
    • To highlight the significance of specific tests in diagnosing male infertility.

    Main Methods:

    • Review of motility tests for human spermatozoa.
    • Examination of the zona-free hamster oocyte penetration test.
    • Analysis of hamster oocyte tests in the presence of A 23187.

    Main Results:

    • Motility tests and the zona-free hamster oocyte penetration test are critically reviewed.
    • Hamster oocyte tests with A 23187 correlate with in vivo fertility.
    • These tests may reduce false negative diagnostic scores.

    Conclusions:

    • Hamster oocyte penetration tests with A 23187 show clinical value.
    • Data from these tests can aid in identifying the causes of male infertility.
    • This approach may lead to improved detection and treatment techniques.
