Semen Analysis Test: What It Shows About Male Fertility

Male fertility plays a major role in conception. In fact, male factors contribute to around 40 – 50% of infertility cases.

One of the most important tests used to evaluate male fertility is a semen analysis test. This laboratory test examines the quality, quantity, and movement of sperm in semen.

It provides valuable insights into:

• Reproductive health
• Fertility potential
• Hormonal balance
• Possible infections or inflammation

At Marylebone Diagnostic Centre, men can access private semen analysis testing in Central London, with discreet sample collection and fast laboratory results.

What Is a Semen Analysis Test?

A semen analysis is a laboratory test that evaluates the characteristics of semen and sperm.

The test helps doctors understand whether sperm are healthy enough to fertilise an egg.

The analysis focuses on several important factors including:

• Sperm count
• Sperm motility
• Sperm morphology
• Semen volume
• Semen pH
• Liquefaction time

Together, these measurements provide a complete overview of male reproductive health.

What Does a Semen Test Measure?

A semen analysis test examines multiple parameters.

Each one provides important clues about fertility.

1. Semen Volume

Semen volume refers to the amount of fluid released during ejaculation.

The typical reference range is:

1.5 mL to 6 mL

Low semen volume may indicate:

• Hormonal imbalance
• Ejaculatory duct obstruction
• Prostate issues

2. Sperm Concentration

This measures the number of sperm per millilitre of semen.

Normal levels are generally:

15 million sperm per mL or higher

Low sperm count is known as oligospermia.

3. Sperm Motility

Motility measures how well sperm move.

Healthy sperm must swim efficiently to reach the egg.

Poor movement may reduce fertility potential.

4. Sperm Morphology

Morphology evaluates the shape and structure of sperm cells.

Abnormal shape may make fertilisation more difficult.

5. pH Level

Semen pH reflects the chemical balance of reproductive fluids.

Abnormal pH levels may suggest infection or gland dysfunction.

Normal Semen Analysis Values

Doctors use internationally recognised laboratory reference ranges when interpreting results.

These values provide a general guide.

However, fertility depends on multiple factors combined rather than one measurement alone.

Common Semen Abnormalities

Sometimes semen analysis results fall outside normal ranges.

This does not always mean infertility.

However, it may suggest underlying issues.

Low Sperm Count (Oligospermia)

This occurs when sperm concentration is below normal levels.

Possible causes include:

• Hormonal imbalance
• Genetic factors
• Varicocele
• Lifestyle habits

Poor Sperm Motility (Asthenozoospermia)

When sperm cannot swim properly, they may struggle to reach the egg.

Factors affecting motility include:

• Smoking
• Stress
• Heat exposure
• Nutritional deficiencies

Abnormal Sperm Shape (Teratozoospermia)

Poor sperm morphology may reduce fertilisation potential.

No Sperm in Semen (Azoospermia)

This condition occurs when no sperm are detected in the semen sample.

Specialist fertility evaluation may be required.

Blood in Semen (Hematospermia)

Some men search online about blood in semen.

This condition is called hematospermia.

In many cases, it is harmless and temporary.

Possible causes include:

• Prostate inflammation
• Infection
• Recent medical procedures
• Minor gland injury

However, persistent blood in semen should be evaluated by a medical professional.

A semen test can help identify possible causes.

Yellow Semen: Is It Normal?

Another common concern is yellow semen.

Semen colour can vary slightly depending on several factors.

Possible causes include:

• Aging semen after longer abstinence
• Diet
• Certain vitamins or medications
• Mild infection

Most cases are harmless.

However, if yellow semen is accompanied by pain, smell changes, or other symptoms, medical testing may be recommended.

When Should You Get a Semen Analysis?

Doctors may recommend a semen test in several situations.

Difficulty Conceiving

Couples who have been trying to conceive for 6–12 months should consider fertility testing.

Recurrent Miscarriage

Male sperm quality can influence pregnancy outcomes.

Planning Fertility Treatment

Many fertility clinics require semen analysis before treatment.

General Health Screening

Some men choose semen testing simply to understand their reproductive health.
