Can I Get a Sperm DNA Fragmentation Test on the NHS in London?
Understand NHS availability, current clinical guidance and your options for private testing at MDC in Marylebone.
Not routinely available on the NHS—but “private only” is too absolute
Sperm DNA fragmentation testing is not a routine NHS fertility investigation. NICE’s 2026 fertility guideline recommends against carrying out the test. Private testing is available at Marylebone Diagnostic Centre.
Some NHS service information nevertheless describes access for NHS patients. Ask your London fertility team whether any local pathway applies to you and whether it is NHS-funded or self-funded.

Three points to understand before booking
What does NICE recommend?
NICE guideline NG257, recommendation 1.17.6, advises against sperm DNA integrity testing. Its rationale highlights uncertainty about interpretation and whether treatment prompted by the result improves outcomes.
Read the NICE recommendationDoes the NHS ever mention offering it?
Yes. A Cambridge University Hospitals patient leaflet describes DNA fragmentation testing and reporting arrangements for NHS and self-funded patients.
This is outside London and does not confirm current eligibility or funding for London patients.
Read the NHS patient leafletCan I get it NHS-funded in London?
Our review did not establish a routine NHS-funded London pathway. Your fertility team should confirm current local arrangements.
A test offered at an NHS hospital may still be self-funded. Ask specifically who pays.
Can my GP arrange fertility tests?
NHS fertility assessment
Your GP can assess fertility concerns and arrange appropriate investigations or referral. The NHS lists semen analysis as a test used to investigate male infertility.
Seek advice after a year of trying to conceive, or sooner if the partner trying to become pregnant is 36 or over, or either partner has a known fertility concern.
NHS guidance on fertility assessmentSemen analysis is a different test
Semen analysis examines sperm count, movement and shape. DNA fragmentation testing assesses damage to sperm DNA. One does not automatically include the other.
If you already have a semen analysis report, bring it to your consultation before deciding whether another investigation is appropriate.
Explore semen analysis at MDCWhy might a specialist discuss DNA fragmentation testing?
Guidance differs. The European Association of Urology supports testing in selected situations, including unexplained infertility, recurrent pregnancy loss and unsuccessful assisted reproduction. NICE recommends against testing.
This difference deserves a conversation with your clinician. Before paying for a test, ask what the result could change in your care and what evidence supports that change.
What question are we answering?
Clarify why the test is being considered in your case, taking account of your history and previous investigations.
Will the result change the plan?
Ask what would happen after either a higher or lower result, particularly if IVF or ICSI is already planned.
What are the limitations?
Results cannot guarantee or rule out pregnancy. The HFEA highlights limited evidence that interventions recommended after testing improve fertility outcomes.

Semen Analysis
Explore testing of sperm count, movement and shape, alongside other semen characteristics.
A useful starting point to discuss if you have not yet had a male fertility assessment.
Other investigations may be appropriate after clinical assessment. Explore male hormone testing or MDC blood tests . Additional testing should address a specific clinical question.
Questions patients ask
Can I ask my GP about sperm DNA testing?
Yes. Discuss your concerns and existing results. Asking does not guarantee an NHS-funded test; your GP or fertility team can explain the available pathway.
Does a normal semen analysis exclude DNA fragmentation?
No. These investigations assess different aspects of sperm health. That does not mean everyone with a normal semen analysis needs DNA testing.
Is Halosperm the same as SCD?
Halosperm is a commercial sperm chromatin dispersion test, often abbreviated to SCD. It assesses patterns around processed sperm nuclei under a microscope.
Can I compare results from different laboratories?
Discuss the assay and reference range with your clinician. Halosperm/SCD, SCSA and COMET use different methods; their numbers and thresholds are not interchangeable.
Can I share a private result with my NHS team?
You can share your report. Before testing, ask whether your NHS team would use the result and whether it could affect your care. They may not recommend changes based on it.
Do I need to stop my NHS fertility investigations?
Do not cancel or delay planned care solely to arrange an additional private test. Discuss timing with your treating team, especially during an IVF or ICSI pathway.
Guidance, regulation and your care
NICE
The National Institute for Health and Care Excellence publishes clinical guidance. NG257 is the fertility guideline relevant to this question.
