Computerized semen analysis offers improved accuracy over subjective methods. The Hamilton Thorn Motility Analyzer (HTM 2000) demonstrated superior sperm count evaluation in patient populations compared to the Cell Soft Semen Analyzer.

Area of Science:

  • Andrology
  • Reproductive Medicine
  • Medical Technology

Background:

  • Semen analysis is crucial for male infertility investigation.
  • Subjective semen evaluation is susceptible to observer bias.
  • Computerized semen analyzers aim to reduce subjectivity and error.

Purpose of the Study:

  • To evaluate and compare the accuracy of two popular computerized semen analyzers: Cell Soft and Hamilton Thorn Motility Analyzer (HTM 2000).
  • To assess the performance of these automated systems against traditional methods and experienced technician evaluation.

Main Methods:

  • Semen samples from 25 normal donors and 25 subfertile patients were analyzed.
  • Two automated analyzers (Cell Soft, HTM 2000) and manual methods (Makler chamber, hemocytometer) were used.

  • Sperm count and motility were analyzed across different sperm density groups.

    • Main Results:

    • The HTM 2000 showed superiority in evaluating sperm count within the subfertile patient group.
    • Both automated systems provided highly accurate counts for donor samples with high sperm density (>85 million/ml).
    • Variations in sperm count and motility were analyzed based on sperm density.

    Conclusions:

    • Computerized semen analysis can mitigate observer bias inherent in subjective evaluations.
    • The HTM 2000 appears more reliable for sperm count assessment in clinical infertility populations.
    • Automated systems offer accurate semen analysis, particularly for samples with higher sperm concentrations.
