Male Fertility – Sperm DNA Fragmentation (SDF) Testing 

Male fertility plays an equal role in conception, yet it is often under-investigated. If you are looking for male fertility testing in Edinburgh, structured diagnostic testing can provide clearer insight when trying to conceive or preparing for IVF or ICSI.

Male fertility reflects overall health. Factors such as oxidative stress, inflammation, metabolic health and lifestyle can influence sperm DNA integrity. Before progressing to assisted reproductive treatment, it is often helpful to assess and optimise these foundations. Testing helps clarify whether targeted health changes or further medical input may be appropriate.

I coordinate and deliver the Scottish hub for Examen Sperm DNA Fragmentation (SDF) testing in partnership with The Natural Fertility Centre on Albany Street in Edinburgh.

Examen is a specialist UK laboratory dedicated to advanced sperm DNA analysis. All testing is processed through an accredited UK laboratory. 

What is Sperm DNA Fragmentation?

Sperm DNA fragmentation measures the proportion of sperm carrying breaks or damage within their genetic material.

Higher fragmentation levels mean a greater percentage of sperm contain DNA damage. Lower levels indicate better overall DNA integrity.

Lower levels are generally associated with improved fertility outcomes.

Importantly:

• It does not mean every sperm is damaged


• It does not mean pregnancy cannot happen


• It does not automatically require invasive treatment

Sperm are renewed continuously, so DNA quality can change over time.

When is SDF Testing Helpful?

SDF testing provides additional insight beyond standard semen analysis and may be helpful in situations such as:

• Unexplained infertility


• Recurrent pregnancy loss


• Previous IVF or ICSI cycles that have not progressed


• Known or suspected sperm quality concerns


• Men wanting a clearer understanding of sperm health

Results are typically available within two weeks once the sample reaches the laboratory.

Other local support

Many men complete semen analysis or oxidative stress testing before moving on to SDF testing. Where appropriate, I collaborate with Georgie McCulloch at Fertility and Pregnancy Edinburgh, who provides male assessment including semen analysis and reactive oxidative stress testing.

Examen offers three levels of sperm DNA fragmentation testing, depending on the depth of analysis required.
