Summary
Sperm DNA fragmentation (SDF) testing is crucial for reproductive success. This review clarifies its clinical utility in various infertility cases, guiding patient management and treatment decisions.
Area of Science:
- Reproductive Medicine
- Genetics
- Clinical Diagnostics
Background:
- Sperm DNA integrity is vital for successful human reproduction.
- High sperm DNA fragmentation (SDF) negatively impacts natural and assisted reproductive technology (ART) outcomes.
- The clinical indications for SDF testing remain less defined despite its known impact.
Discussion:
- This practice recommendation summarizes current evidence on the clinical utility of SDF testing.
- It explores SDF testing's role in specific patient groups, including varicocelectomy candidates, couples with recurrent pregnancy loss, unexplained infertility, and failed ART.
- Expert panel recommendations with evidence levels are provided for each clinical scenario.
Key Insights:
- SDF testing offers valuable insights into male infertility beyond traditional semen parameters.
- Evidence supports SDF testing in selected cases of recurrent pregnancy loss and unexplained infertility.
- SDF testing can guide treatment decisions, potentially improving reproductive outcomes.
Outlook:
- Further research is needed to refine SDF testing protocols and establish universal clinical guidelines.
- Integrating SDF testing into routine infertility workups may enhance personalized reproductive medicine.
- Future studies should focus on the impact of SDF levels on specific ART techniques and live birth rates.
