Clinical Report: Correlation Between Semen Leukocyte Counts and Sperm DNA Fragmentation
Overview
This study investigates the relationship between sperm DNA fragmentation index (DFI) and semen leukocyte counts in a clinical population. Findings indicate that DFI is inversely correlated with semen motility and CASA kinematics, while positively associated with semen leukocyte counts.
Background
Sperm DNA fragmentation is a critical factor in male reproductive health, influencing fertilization and pregnancy outcomes. Understanding its correlation with semen parameters and systemic biomarkers is essential for improving diagnostic accuracy in male infertility. This study aims to elucidate these relationships to enhance clinical practices.

Key Findings
DFI increases with age and is inversely related to semen motility.
Semen leukocytes show a positive correlation with DFI, indicating inflammation's role in sperm DNA integrity.
Albumin exhibits the strongest inverse correlation with DFI among systemic biomarkers.
The predictive model for high DFI demonstrated good discrimination (AUC 0.783).
Nonlinear associations between leukocyte counts and DFI were observed.
Clinical Implications
Clinicians should consider sperm DNA fragmentation as a significant factor in male infertility evaluations, particularly in cases of unexplained infertility or recurrent pregnancy loss. Monitoring semen leukocyte counts may provide additional insights into inflammatory processes affecting sperm quality.
Conclusion
The study highlights the importance of assessing sperm DNA fragmentation and associated biomarkers in clinical practice. Further validation of these findings is necessary to enhance the management of male infertility.
