Objective:

To identify potential diagnostic biomarkers for nonobstructive azoospermia (NOA) through gene expression analysis, which could improve noninvasive diagnosis and clinical management.

Key Findings:
  • AKT1, ASNS, and SHC1 showed AUC values greater than 0.7 in both training and validation data sets.
  • Significant upregulation of AKT1 and SHC1 in NOA patients was observed, while ASNS showed lower expression without statistical significance, indicating a need for further investigation.
  • Functional enrichment analyses indicated involvement in male gamete generation and spermatogenesis, with potential links to immune dysregulation.
Interpretation:

The identified biomarkers may play a role in germ cell development and could be linked to immune dysregulation in NOA pathophysiology, suggesting avenues for future research.

Limitations:
  • Small sample sizes in public gene-expression data sets limit the robustness of findings.
  • Tissue-based sampling may restrict generalizability to broader populations.
  • Limited experimental validation raises concerns about potential overfitting and the reliability of results.
Conclusion:

The findings are preliminary and require larger studies for validation before clinical application in diagnosing NOA, emphasizing the need for further research.
