What is a semen analysis test?
A semen analysis test is an important first step in assessing male fertility. It involves analysing a semen sample to check important factors such as sperm count, motility (movement), and morphology (shape).
This test provides valuable insight into your reproductive health and can help identify any issues that might be affecting your chances of conception. Your results can also guide the next steps in your fertility treatment plan.
We’ll turn your results into a comprehensive report that covers everything from sperm count to motility and morphology. You can download a semen analysis sample report before your appointment to get a feel for what your results report could look like.
Comprehensive Semen Analysis in our London Clinic is just £139.

Other sperm tests we offer
In some cases, a standard semen analysis may not give the full picture. That’s why, in collaboration with leading andrology laboratories across the UK and Europe, Northway Clinic can refer you for a range of advanced sperm tests to support your fertility journey.
If required, our team will guide you through preparation and arrange your appointment at a specialist lab in central London. Your sample will be processed on-site or safely transported for further analysis.
Please note: a consultation or referral from your fertility specialist may be necessary.
Sperm DNA fragmentation
Sperm DNA fragmentation happens when the genetic material inside sperm becomes damaged. It’s more common than many people realise and can sometimes make it harder to conceive or increase the risk of miscarriage, even if a standard semen analysis looks normal. Understanding this can be a helpful next step on your fertility journey.
At Northway Clinic, we offer two main types of sperm DNA fragmentation tests – the SCSA DNA fragmentation test and the COMET® DNA fragmentation test.
The SCSA DNA fragmentation test (£290) rapidly measures possible DNA damage across thousands of sperm cells. This test may be suitable for you if you have a sperm count of at least 100,000/ml and provides quick, reliable results to support early fertility assessments.
The COMET® DNA fragmentation test (£430) is a highly detailed test that analyses specific types of DNA. It’s also suitable for those with low sperm counts or surgically retrieved sperm, as it only requires 5,000 sperm. Powered by SpermComet technology, Examen sperm DNA fragmentation (SDF) tests directly measure SDF damage within the sperm cell itself (i.e. unlike some other tests which measure only an indirect proxy for SDF damage.
COMET® test variants
There are several COMET® test variants, each tailored to different fertility challenges.
| Test name | Recommended for | Price |
| COMET Exact (CMET) | Difficulty conceiving despite a normal semen analysis. Provides a broad view of sperm DNA integrity. | £430 |
| COMET Extend (CMT3) | Recurrent miscarriage or advanced ART planning. Provides deeper insight into the nature and severity of DNA damage. | £590 |
| COMET Extensiv (CMT5) | IVF failure and pregnancy loss, where ART did not progress due to post-implantation failures | £960 |

Semen analysis FAQs (frequently asked questions)
Can I do a semen analysis at home?
No – at Northway Clinic, we carry out semen analysis on-site to ensure the sample is processed quickly and accurately. Home tests may not provide reliable results or the full details needed to assess your fertility properly.
Do I need to abstain before my appointment?
Yes. For the most accurate results, we usually recommend abstaining from ejaculation for 2 to 5 days before your semen analysis. We’ll confirm the exact guidance when you book.
Will the test be uncomfortable or embarrassing?
We understand this can feel like a sensitive subject. That’s why we provide a clean, private and discreet environment, and our team will treat you with total respect and professionalism throughout your visit.
How long do semen analysis results take?
In most cases, results are available the same or the next working day. If there’s likely to be a delay, we’ll let you know in advance.
What if my results are abnormal?
Don’t worry – abnormal results are not uncommon and don’t necessarily mean you can’t conceive. We can help guide your next steps, whether that’s further testing, lifestyle advice or a referral to a fertility specialist.
