Sample: Sperm
Results: 15 days
A sperm DNA fragmentation test that reports the proportion of sperm with fragmented DNA as a DNA fragmentation index (DFI). This gives a clinician another measurement to consider alongside a fertility assessment; it does not predict an individual pregnancy outcome.
• Sperm DNA fragmentation index (DFI) measured by TUNEL assay, SCSA (Sperm Chromatin Structure Assay), or a similar method
• Determines the percentage of sperm with damaged DNA
• Results correlate with fertilisation rates, embryo quality, pregnancy outcomes and miscarriage risk
• Useful when standard semen analysis is normal but fertility issues persist
It reports a sperm DNA fragmentation index (DFI) - the percentage of sperm with damaged DNA - measured by TUNEL, SCSA, or a similar method.
The source specifies a sperm sample; ask the clinic for collection instructions.
TUNEL assay, SCSA (Sperm Chromatin Structure Assay), or a similar method. Confirm the exact assay used with the clinic.

No. A clinician should interpret it alongside your wider fertility assessment.
