ERA (Endometrial Receptivity Array) Test in London

Sperm DNA Fragmentation Test in London

Sperm health plays an important role in fertility. A standard semen analysis checks count, movement and shape, but it does not assess sperm DNA damage.

At The Luna Clinic, our sperm DNA fragmentation test in London looks deeper at sperm DNA quality and can help investigate unexplained fertility problems, recurrent miscarriage and failed fertility treatment.

Get clearer answers about your sperm health with expert testing and personalised fertility guidance at The Luna Clinic.

What Is a Sperm DNA Fragmentation Test?

A sperm DNA fragmentation test assesses the amount of damage or breaks in the DNA carried by sperm. This is known as sperm DNA fragmentation (SDF).

A man can have a normal sperm count and still have a higher level of DNA fragmentation. This is why DNA integrity testing can provide information that is not always captured by a conventional semen analysis.

The test is particularly useful when a fertility specialist wants to look beyond basic sperm parameters and understand whether sperm DNA quality could be contributing to difficulties conceiving or fertility treatment outcomes.

Who Can Benefit From Our Sperm DNA Fragmentation Test in London?

Our fertility specialists recommend sperm DNA fragmentation testing if you have experienced:

Difficulty conceiving despite trying naturally
Abnormal or borderline semen analysis results
Repeated miscarriage
Failed fertility treatment
Poor embryo development
Previous IVF or ICSI treatment with disappointing outcomes
Concerns about sperm quality
Possible lifestyle or environmental factors affecting sperm health

The test may also be considered when standard fertility investigations have not clearly explained why pregnancy has not occurred.

Fertility Conditions and Concerns We Investigate

As the leading fertility clinic in London, we use sperm DNA fragmentation testing to explore potential male fertility factors that may be missed by routine semen analysis. It can provide valuable insight when you are facing:

Male Infertility

At The Luna Clinic, we use sperm DNA fragmentation testing as part of a wider assessment of male infertility. It can provide information that a routine semen analysis may not show.

Our specialists consider your results alongside sperm count, motility, morphology and your fertility history to build a clearer picture of your reproductive health.

Unexplained Infertility

When standard fertility tests look normal, but pregnancy is still not happening, there may be factors that need further investigation. Sperm DNA integrity can be one of them.

Our sperm DNA fragmentation test can provide additional insight into sperm health and help your specialist decide whether further assessment is appropriate.

Recurrent Miscarriage

Experiencing repeated miscarriages can be extremely difficult. In some cases, sperm DNA integrity may be considered as part of a wider fertility investigation.

At The Luna Clinic, we can assess sperm DNA fragmentation alongside other relevant fertility factors to help identify potential concerns.

Recurrent Implantation or Fertility Treatment Failure

Repeatedly unsuccessful IVF or ICSI treatment can leave couples searching for answers. Sperm DNA fragmentation testing may provide useful additional information about sperm quality.

Our specialists can review your previous treatment history and test results to determine whether sperm DNA damage may be relevant to your fertility journey.

Poor Embryo Development

Sperm contributes genetic material to the developing embryo, so sperm quality can be an important part of the fertility picture. Poor embryo development may sometimes prompt further investigation.

At The Luna Clinic, sperm DNA fragmentation testing can help assess whether sperm DNA integrity is a factor worth considering.

Reduced Sperm Quality

A low sperm count, reduced motility or abnormal sperm morphology can indicate reduced sperm quality. However, these standard measures do not tell the whole story.

Our DNA fragmentation testing provides another layer of information, helping your specialist assess sperm health more comprehensively.

Suspected Sperm DNA Damage

Sperm DNA can be affected by factors such as oxidative stress, smoking, heat exposure, certain health conditions, and increasing age. If these factors are present, further assessment may be appropriate.

At our IVF clinic in London, we consider your individual circumstances before recommending testing, helping ensure your fertility assessment is relevant to your needs.

Other Male Fertility Factors

Many factors, including hormones, testicular health, previous infections, medications, lifestyle and conditions such as varicocele can influence male fertility.

Our specialists take a broader view of your fertility rather than focusing on one result. Sperm DNA fragmentation testing can be combined with other investigations where clinically appropriate.

What Causes Sperm DNA Fragmentation?

Sperm DNA fragmentation can have several possible causes. These may include:

Oxidative stress
Smoking and tobacco exposure
Excessive alcohol consumption
Increasing paternal age
Varicocele
Infections or inflammation
High testicular temperature
Certain medical conditions
Some medications or treatments
Environmental or occupational exposures
Poor general lifestyle and metabolic health

Having one of these factors does not necessarily mean that you have high sperm DNA fragmentation.

Testing is needed to understand your individual situation.

Process of Our Sperm DNA Fragmentation Test

We keep the testing process simple.

Step 1: Book Your Consultation

Start with a consultation at The Luna Clinic. Your fertility specialist will discuss your fertility history, previous investigations, and any concerns about sperm health before recommending the most appropriate testing.

Step 2: Provide Your Sample

You will be given clear instructions about providing your semen sample.

Following the clinic’s preparation guidance helps ensure the sample can be assessed appropriately.

Step 3: Test Your Sperm DNA

The laboratory analyses the semen sample using a validated sperm DNA fragmentation testing method. The result provides an indication of the proportion of sperm showing DNA fragmentation.

Step 4: Review Your Results

Your specialist will explain what your result means in the context of your fertility history. A result is not interpreted on its own; other sperm parameters, female fertility factors and previous treatment outcomes may also be considered.

Understanding Your Sperm DNA Fragmentation Results

Sperm DNA fragmentation results are generally reported as a DNA Fragmentation Index (DFI) or a similar measure, depending on the testing method used.

The exact interpretation can vary between laboratory methods, so your clinic should explain the reference range used for your test.

DFI Level	Meaning	Potential Impact
Low	Less DNA damage	More favourable
Intermediate	Moderate DNA damage	May affect fertility
High	More DNA damage	May reduce fertility potential

A higher result does not mean that natural conception or fertility treatment is impossible.

It is one part of the overall fertility picture and should be interpreted by a fertility professional.

Sperm DNA Fragmentation and Fertility Treatment

Sperm DNA fragmentation testing can sometimes help fertility specialists decide whether additional strategies should be considered before or during treatment, such as IVF or ICSI.

Depending on the results and your circumstances, your fertility team may discuss lifestyle changes, treatment of an underlying male fertility problem, antioxidant strategies where appropriate, or different approaches to sperm selection or assisted reproduction.

The right approach depends on the cause of the fertility problem and the results of the wider fertility assessment.

Sperm DNA Fragmentation Test Cost in London

The cost of a sperm DNA fragmentation test in London can vary depending on the testing method and whether it is included in a wider fertility assessment.
