Semen Analysis and Male Fertility: Everything You Need to Know
Male infertility affects around 1 in 7 couples in the UK, and semen analysis is one of the first tests recommended to assess fertility. Whether you’re trying for a baby or simply want to check your reproductive health, a semen analysis can provide essential insights into your sperm count, motility, and morphology.
At Marylebone Diagnostic Centre, 73 Baker Street, we offer discreet and accurate semen testing with fast turnaround times, helping you take the next step with confidence.
In this guide, we’ll cover the top information around semen analysis, sperm health, and answer the most common questions men have before booking a test.
Low Sperm Count
A low sperm count (oligospermia) means there are fewer sperm in your semen than expected. A normal count is considered 15 million sperm per millilitre of semen or higher. Anything below this range may reduce the chances of natural conception.
Causes of low sperm count include hormonal imbalances, lifestyle factors, testicular injury, or medical conditions such as varicocele.
Semen Analysis: Purpose, Procedure & Results
Purpose
A semen analysis checks sperm quality to understand fertility potential. It looks at:
- Sperm count (concentration)
- Sperm motility (movement)
- Sperm morphology (shape)
- Semen volume and consistency
Procedure
You will be asked to provide a semen sample through masturbation into a sterile container. At Marylebone Diagnostic Centre, we provide a private and discreet setting to make the process as comfortable as possible.
Results
Results are usually available within 24–48 hours. They can indicate whether sperm quality is within a normal range, or if further tests and treatments may be required.
Diagnosis of Infertility
Semen analysis is often the first step in diagnosing male infertility. If abnormalities are found, additional tests may include:
- Hormone blood tests
- Scrotal ultrasound
- Genetic testing
- Specialist urology referral
At MDC, we combine semen analysis with male hormone blood tests for a more complete picture of reproductive health.
Sperm Morphology: What Does It Mean?
Sperm morphology refers to the size and shape of sperm. Normal sperm have an oval head and a long tail. Abnormalities in shape can affect the ability of sperm to swim or penetrate the egg.
While some abnormal forms are common, a higher percentage of normally shaped sperm improves fertility outcomes.
IVF and ICSI Treatments
Men with severe sperm abnormalities may benefit from assisted reproductive techniques such as:
- IVF (In Vitro Fertilisation): Eggs are fertilised with sperm in a lab.
- ICSI (Intracytoplasmic Sperm Injection): A single healthy sperm is injected directly into the egg.
Semen analysis is always required before starting treatment, and MDC can provide a referral pathway if advanced fertility options are needed.
Normal Sperm Count: Understanding Your Semen Analysis
According to WHO guidelines as of 2021, normal semen parameters include:
- Volume: At least 1.5ml
- Concentration: At least 15 million sperm per ml
- Motility: 40% or more moving sperm
- Morphology: 4% or more normal-shaped sperm
It’s important to remember that results vary, and even men with borderline parameters can still achieve pregnancy.
Low Sperm Motility: Causes, Ranges, and Treatment
Low sperm motility (asthenozoospermia) means sperm do not swim efficiently. Causes include:
- Varicocele
- Infections
- Hormonal issues
- Lifestyle factors such as smoking, alcohol, or obesity
Treatments may involve lifestyle changes, supplements, or assisted reproduction if natural conception is difficult.
Understanding Semen Analysis
A semen analysis provides key data about male reproductive health. It is often recommended if a couple has been trying to conceive for more than 12 months.
At MDC, our semen analysis includes:
- Total sperm count
- Sperm motility
- Morphology
- Semen pH and vitality
Specialist Male Fertility Clinics
Some men require further investigations or treatments after an abnormal semen analysis. At Marylebone Diagnostic Centre, we can arrange follow-up with fertility specialists, urologists, and IVF clinics if necessary.
Why Testing Early Matters
Early semen testing helps couples avoid long delays in diagnosing infertility. By identifying issues early, you can explore the right treatment pathway – whether medical, surgical, or assisted reproduction.
