Sperm Count Test in London – Understanding Male Fertility
Fertility affects couples emotionally, physically, and socially. Yet, one in six couples struggle to conceive, and in nearly half of these cases, the cause involves male factors. A sperm count test is often the first and simplest step to investigate fertility health.
At Marylebone Diagnostic Centre, we offer discreet, same-day sperm count testing in London. Our laboratory follows the Marylebone High Standard for accuracy and patient care.
What is a sperm count test?
A sperm counts test measures the number of sperm present in one millilitre of semen. It is part of a full semen analysis, which also examines sperm movement (motility) and shape (morphology).
According to the World Health Organization (WHO), a normal sperm concentration is 15 million sperm per millilitre or more. A count lower than that may indicate oligospermia, or low sperm count.
Why sperm count matters
Fertility depends on many factors, but sperm count plays a major role. A higher count increases the chance that sperm will reach and fertilise an egg. However, quality matters as much as quantity.
Even men with normal sperm counts can face fertility issues if sperm movement or shape is poor. That’s why a full semen analysis, not a simple count alone, gives the clearest picture.
Who should consider a sperm count test
Many men believe fertility problems only affect women. In reality, men contribute to fertility challenges just as often. You should consider testing if:
- You and your partner have tried to conceive for six months or more
- You experience reduced libido or erectile difficulties
- You had an infection such as mumps, prostatitis, or epididymitis
- You underwent pelvic or testicular surgery
- You are concerned about hormone changes or chronic stress
- You have used anabolic steroids or testosterone boosters in the past
Early testing can save months of uncertainty and guide you toward solutions.
What the test involves at Marylebone Diagnostic Centre
At 73 Baker Street, Marylebone, testing is simple, private, and handled by experienced clinicians.
- Appointment booking: You can book online or by phone.
- Sample collection: You may provide a sample in a private room or, in some cases, at home under specific conditions.
- Laboratory analysis: Our biomedical team measures sperm count, motility, morphology, and volume using advanced equipment.
- Results: You receive a digital report within 24 hours, explained in clear language by our clinical team.
All procedures follow international standards for temperature control, timing, and handling.
What your results mean
Your results will show:
| Parameter | Normal Range (WHO Reference) |
| Sperm concentration | ≥15 million/ml |
| Total motility | ≥40% |
| Progressive motility | ≥32% |
| Normal morphology | ≥4% |
| Volume | ≥1.5 ml |
If your numbers fall outside these ranges, it does not necessarily mean infertility. Some men with low counts still conceive naturally, while others with normal counts may need support for different issues such as DNA fragmentation or hormone imbalance.

Factors that affect sperm count
Many everyday factors influence sperm production and quality. These include:
- Smoking and alcohol – Both reduce testosterone and sperm motility.
- Stress – High cortisol interferes with reproductive hormones.
- Excess weight – Obesity can lower sperm concentration and volume.
- Heat exposure – Hot tubs, saunas, and tight clothing can impair sperm formation.
- Poor sleep – Disrupted rest reduces hormone balance.
- Nutrient deficiencies – Low zinc, folate, and vitamin D affect sperm DNA quality.
Making small changes can improve results over time.
Improving sperm health naturally
Simple lifestyle improvements can enhance sperm count and function:
- Eat a diet rich in fruits, vegetables, fish, and nuts.
- Stay hydrated and maintain a healthy weight.
- Avoid smoking and reduce alcohol intake.
- Exercise moderately (avoid overtraining).
- Get enough rest and manage stress.
If you take prescription medication or supplements, mention them during your consultation. Some drugs, such as testosterone injections or finasteride, can suppress sperm production.
When to repeat the test
Sperm production takes about 70–90 days, so results reflect the past three months.
If your first test shows low numbers, your clinician may recommend repeating it after lifestyle improvements or treatment.
At Marylebone Diagnostic Centre, follow-up testing is simple and can track your progress accurately.
