- Understanding the Test
What sperm DNA fragmentation actually means
Fragmentation refers to breaks or damage within the genetic strands carried by a sperm cell. A man can have a completely normal count, shape, and motility on a routine semen analysis and still carry a high degree of DNA damage — because standard testing was never built to look at the DNA itself.
Left unchecked, this hidden factor is one of the more common, and most overlooked, explanations behind failed fertilisation, poor embryo development, and pregnancy loss that otherwise has no clear cause.
Oxidative Stress
Smoking, pollution, and prolonged heat exposure generate reactive molecules that damage sperm DNA over time.
Age & Lifestyle
Advancing age, poor diet, sedentary habits, and untreated infections all raise fragmentation levels gradually.
Underlying Conditions
Varicocele, chronic illness, and certain medications are frequently linked to elevated DNA damage in sperm.
- The Procedure
How the test works, start to finish
A straightforward, three-step process carried out entirely in our lab — no invasive procedures, no complicated preparation.
1
Sample Collection
A semen sample is collected on-site following standard preparation guidelines to keep results accurate.
2
Laboratory Analysis
Our embryology team runs a validated DNA fragmentation assay to measure the extent of damage in the sample.
3
Detailed Report
You receive a clear DFI report that our fertility specialists use to shape a targeted next step.
- Why It Matters
Who should consider this test
High fragmentation can quietly lower fertilisation rates and raise miscarriage risk, even when every other fertility marker looks fine. This test is worth having if any of the following sound familiar:
Unexplained Infertility
Every routine test comes back normal, yet pregnancy still isn't happening.
Recurrent Miscarriage
More than one pregnancy loss without a clear medical explanation.
Failed IVF / ICSI Cycles
One or more prior cycles ended without fertilisation or implantation.
Known Risk Factors
Smoking, varicocele, prior chemotherapy, or a physically demanding, high-heat occupation.
- COMMON QUESTIONS
Frequently Asked Questions
It’s a lab test that measures how intact or broken the genetic material inside sperm cells is, going beyond what a routine semen analysis can show.
A semen analysis looks at count, shape, and movement. It says nothing about whether the DNA carried inside each sperm is undamaged, which is exactly what this test measures.
A semen sample is collected on-site and analysed in our lab using a validated fragmentation assay. Your fertility specialist then reviews the report with you and outlines next steps.
Couples facing unexplained infertility, repeated miscarriage, or failed IVF/ICSI cycles, and men with known risk factors such as smoking or varicocele, benefit most from this test.
Often, yes. Depending on the cause, treatment can include lifestyle changes, antioxidant therapy, treating an underlying infection, or choosing an assisted reproduction technique suited to the result.
Yes — it’s a simple, non-invasive lab test with no risk involved. Reports are typically ready within 2–3 working days.
