This study optimized the Hamilton-Thorn HTM-2000 semen analyzer for accurate sperm analysis. Optimal settings ensure reliable sperm concentration and motility measurements, crucial for clinical evaluations.

Area of Science:

  • Andrology
  • Reproductive Medicine
  • Biomedical Engineering

Background:

  • Computerized semen analysis is essential for male fertility assessment.
  • Standardization of operating conditions is needed for reliable results.
  • The Hamilton-Thorn HTM-2000 is a widely used semen analyzer.

Purpose of the Study:

  • To determine the optimal operating parameters for the Hamilton-Thorn HTM-2000 semen analyzer.
  • To evaluate the reproducibility and reliability of sperm parameter measurements.
  • To compare the HTM-2000's performance with other semen analysis systems.

Main Methods:

  • Evaluated optimal frame acquisition (20 frames at 19 frames/s) for sperm concentration.
  • Assessed the impact of the number of fields analyzed on measurement accuracy.

  • Calculated intrasample and intersample coefficients of variation for various sperm parameters.

    • Main Results:

    • Optimal reproducibility for sperm concentration achieved with 20 frames/s.
    • Sperm concentration measurements were not affected by the number of fields analyzed.
    • Intrasample and intersample coefficients of variation ranged from 2.5% to 28.9% across parameters.

    Conclusions:

    • Sampling error significantly influences the reliability of sperm evaluation.
    • The HTM-2000 offers favorable precision and rapidity compared to other systems.
    • Optimized operating conditions enhance the diagnostic accuracy of the HTM-2000.
