Stability of basic semen measures and abnormal morphology within individuals.

M L Poland, K S Moghissi, P T Giblin

    Journal of Andrology
    |July 1, 1986
    PubMed
    Summary

    Semen analysis parameters like sperm count and motility show stability over time. These stable factors aid in individual identification, though the biological basis requires further study.

    Area of Science:

    • Reproductive biology
    • Andrology
    • Spermatogenesis

    Background:

    • Semen analysis is crucial for male fertility assessment.
    • Understanding the stability of semen parameters is key for reliable interpretation.
    • Individual variations in spermatogenesis patterns exist but are not fully understood.

    Purpose of the Study:

    • To assess the relative stability of basic semen measures over a six-month period.
    • To identify stable semen factors that can characterize individuals.
    • To evaluate the potential of these factors in individual identification.

    Main Methods:

    • Semen samples from 15 healthy volunteers were analyzed every two weeks for six months.
    • Key parameters assessed included sperm count, semen volume, sperm motility, and normal morphology.

  • Abnormal morphologic forms were also categorized.

    • Main Results:

    • Basic semen measures demonstrated greater stability compared to abnormal morphologic forms.
    • Seven semen factors, including sperm count, motility, and morphology, were found to be stable across individuals.
    • These stable factors achieved a 75.0% classification accuracy in identifying individuals.

    Conclusions:

    • Semen parameters exhibit a degree of individual stability over time.
    • Specific semen factors can serve as reliable biomarkers for individual characterization.
    • Further research is needed to elucidate the biological underpinnings of observed spermatogenesis patterns.
