This study confirms the Hamilton Thorne Research IVOS semen analyser

Area of Science:

  • Andrology and Reproductive Biology
  • Semen Analysis Technology
  • Sperm Morphology Assessment

Background:

  • Accurate sperm morphology evaluation is crucial for male fertility assessment.
  • Automated semen analyzers offer potential for standardized and efficient analysis.
  • The Hamilton Thorne Research IVOS system is widely used, necessitating validation of its repeatability.

Purpose of the Study:

  • To investigate the repeatability of the Hamilton Thorne Research IVOS (version 10) semen analyser for sperm morphology assessment.
  • To evaluate cell-cell, intraslide, and interslide repeat measures using strict criteria.
  • To determine the system's precision and accuracy in routine semen analysis.

Main Methods:

  • Semen samples with varying normal sperm morphology were prepared and stained.

Related Experiment Videos

  • Repeatability was assessed using cell-cell, intraslide, and interslide measures.
  • Agreements were analyzed using kappa statistic and average coefficients of variation.

    • Main Results:

    • High predictive probabilities for consistent cell outcomes (91-95%).
    • Average coefficients of variation for intraslide trials were 9.73% (100 cells) and 8.30% (200 cells).
    • Average coefficient of variation for interslide trials was 15.39%.

    Conclusions:

    • The Hamilton Thorne Research IVOS system demonstrates acceptable repeatability, precision, and accuracy for routine semen analysis.
    • Proper sample preparation and staining techniques are critical for reliable results.
    • The system's performance supports its application in clinical andrology settings.
