This study analyzed semen analysis data from over 9,000 records to identify key indicators of male fertility. Sperm concentration, forward motility, and morphology are crucial for distinguishing between fertile and infertile individuals.

Area of Science:

  • Reproductive Medicine
  • Andrology
  • Statistical Analysis in Healthcare

Background:

  • Male infertility is a significant concern, necessitating accurate diagnostic tools.
  • Semen analysis is a cornerstone of male reproductive health assessment.
  • Understanding the statistical relationships between semen parameters and fertility outcomes is vital.

Purpose of the Study:

  • To statistically analyze a large dataset of semen analyses and anamnestic data.
  • To identify key semen parameters that effectively differentiate between fertile and infertile men.
  • To explore the utility of multivariate statistical analysis in male fertility assessment.

Main Methods:

  • Retrospective statistical study utilizing a large cohort of semen analysis records (n=9384).

  • Creation of multiple patient subgroups based on the frequency of semen analysis (P-1 to P-4).
  • Inclusion of control groups: sperm-bank donors (DON) and prevasectomy subjects (VAS).
  • Application of frequency distributions and cluster analyses.
  • Multivariate statistical analysis to determine discriminating factors.

    • Main Results:

    • Multivariate analysis successfully distinguished between fertile and infertile subjects based on clinical data.
    • Sperm concentration was identified as a significant discriminating parameter.
    • Forward sperm motility and sperm morphology emerged as the most powerful indicators of fertility status.

    Conclusions:

    • Semen analysis, particularly focusing on sperm concentration, forward motility, and morphology, is highly effective in assessing male fertility.
    • Multivariate statistical approaches can enhance the diagnostic accuracy of semen analysis.
    • These findings can aid clinicians in better diagnosing and managing male infertility.
