When a couple has difficulty conceiving, our doctors evaluate both partners. Although fertility problems can arise from female, male or combined factors, male factors contribute to infertility in a substantial proportion of couples. Current European guidance recommends evaluating both partners rather than focusing only on the woman.

For the male partner, semen analysis is one of the most important initial investigations.

The test examines semen and sperm characteristics that can provide valuable information about sperm production and reproductive function. Our doctors use the results to decide whether a man needs further evaluation, whether a potentially treatable problem may be present, and which fertility treatment options may be appropriate.

The World Health Organization (WHO) 6th edition Laboratory Manual for the Examination and Processing of Human Semen provides standardized methods for examining semen and sperm. Following standardized laboratory procedures helps improve the quality and comparability of semen-analysis results.

At Jyoti Hospital, Gurugram, our Urology and Andrology team use semen analysis as part of a comprehensive male-fertility evaluation. The team can interpret the report alongside the man’s medical history, physical examination, reproductive history and other investigations when required.

What Is Semen Analysis?

Semen analysis, also called a semen test or sperm test, is a laboratory examination of an ejaculated semen sample.

The test evaluates several characteristics of the semen and sperm, including:

• Semen volume
• Sperm concentration
• Total sperm number
• Sperm motility
• Sperm morphology
• Presence of other cells or abnormalities
• Other parameters depending on the laboratory’s examination protocol

The WHO 6th edition manual describes standardized procedures for basic, extended and advanced semen examinations.

Our doctors use this information to understand whether the male reproductive system is producing and delivering sperm in a way that may support conception.

However, a semen analysis does not provide a simple yes-or-no answer about fertility.

A man can have abnormal semen parameters and still father a child, while a man with parameters within reference ranges can still experience infertility because fertility depends on multiple factors affecting both partners.

Why Is Semen Analysis Important in Infertility Evaluation?

Semen analysis plays an important role because it provides objective information about several aspects of male reproductive function.

1. It helps assess sperm production

The test measures the number of sperm present in the semen.

A low sperm concentration or low total sperm number may suggest reduced sperm production or another underlying problem.

Our doctors then investigate possible causes such as:

• Varicocele
• Hormonal disorders
• Testicular problems
• Genetic conditions
• Previous testicular injury
• Certain infections
• Medications or treatments
• Exposure to factors that can affect sperm production

2. It evaluates sperm movement

Sperm need appropriate movement to travel through the female reproductive tract and reach the egg.

Semen analysis therefore evaluates sperm motility.

The laboratory assesses how many sperm are moving and how they move.

Reduced motility may affect the ability of sperm to reach and fertilize an egg.

Our doctors call significantly reduced sperm motility asthenozoospermia.

However, our doctors interpret motility together with the other semen parameters rather than treating one number as a standalone diagnosis.

3. It evaluates sperm morphology

Sperm morphology refers to the size and shape of sperm.

The laboratory evaluates sperm according to standardized morphological criteria.

A lower proportion of normally shaped sperm can occur in men who experience fertility problems.

However, morphology alone does not determine whether a man can father a child.

Our doctors consider morphology alongside sperm concentration, motility, total sperm number and the couple’s clinical circumstances.

4. It measures semen volume

The amount of semen produced during ejaculation can provide useful information.

A very low semen volume can sometimes occur with:

• Incomplete collection
• Dehydration
• Ejaculatory problems
• Retrograde ejaculation
• Obstruction of the reproductive tract
• Certain hormonal or glandular problems

Our doctors interprets low semen volume alongside other findings rather than assuming that it automatically indicates infertility.

5. It can identify very low sperm counts or absence of sperm

Semen analysis can detect situations in which sperm numbers are extremely low or sperm cannot be identified in the ejaculate.

When no sperm are found, doctors may describe the condition as azoospermia.

Azoospermia does not always mean that the testes produce no sperm.

Our doctors distinguish between:

• Obstructive azoospermia, where sperm production may continue but an obstruction prevents sperm from reaching the ejaculate.
• Non-obstructive azoospermia, where sperm production itself is significantly impaired.

Further evaluation can help determine the cause and whether sperm retrieval or other fertility treatment may be possible.

What Does a Semen Analysis Measure?

A standard semen analysis generally assesses several important parameters.

Semen Volume

This measures the amount of semen produced in the sample.

Volume provides useful information about the ejaculatory process and the secretions contributing to semen.

Sperm Concentration

Sperm concentration refers to the number of sperm present per unit volume of semen.

A low concentration can indicate oligozoospermia.

However, concentration alone does not describe the entire sperm output.

The WHO 6th edition emphasizes the diagnostic importance of assessing total sperm number per ejaculate, which requires accurate measurement of semen volume.

Total Sperm Number

Total sperm number refers to the total number of sperm present in the entire ejaculate.

This value can provide additional information beyond sperm concentration because it takes semen volume into account.

Sperm Motility

Motility describes how sperm move.

The laboratory assesses the proportion of sperm that are:

• Progressively motile
• Non-progressively motile
• Immotile

The WHO 6th edition provides standardized approaches for assessing sperm motility.

Sperm Morphology

Morphology assesses sperm shape and structure.

The laboratory evaluates sperm according to standardized criteria.

Abnormal morphology may occur alongside other semen abnormalities, but our doctors do not use morphology alone to determine whether a man is fertile or infertile.

What Does a Semen Analysis Report Tell You?

A semen report can provide a snapshot of several aspects of male reproductive function.

For example, the report may show:

Parameter	What it tells the doctor
Semen volume	Amount of ejaculate
Sperm concentration	Number of sperm per unit volume
Total sperm number	Total sperm output
Motility	How well sperm move
Progressive motility	How effectively sperm move forward
Morphology	Sperm shape and structure
Other cells	May provide clues requiring further evaluation

Our doctor interpret these values together. A single number rarely tells the complete story.

What Are WHO Reference Values?

The WHO publishes standardized laboratory procedures and reference distributions for semen characteristics.

However, patients should understand an important distinction:

WHO reference values are not a strict line separating fertile men from infertile men.

A man whose semen parameter falls below a reference value does not automatically have infertility. Likewise, a man whose results fall within the reference distribution does not automatically have normal fertility.

The WHO manual specifically cautions against using semen parameters as absolute limits between fertile and subfertile men.

Our doctors interpret semen results alongside:

• Duration of infertility
• Female partner’s fertility assessment
• Sexual history
• Medical history
• Physical examination
• Previous pregnancies
• Other semen analyses
• Hormonal findings
• Imaging
• Genetic testing when indicated

Does One Abnormal Semen Analysis Mean Infertility?

No. This is one of the most important things patients should understand.

Semen parameters can vary between samples. Factors such as illness, fever, temporary stress, incomplete collection and changes in abstinence period can influence the result.

Therefore, when the initial semen analysis is abnormal, doctors may recommend a repeat analysis.

Current EAU guidance recommends at least two consecutive semen analyses when the baseline analysis is abnormal.

A repeat test can help determine whether an abnormal finding persists.

How Is Semen Collected for Analysis?

The laboratory generally provides instructions for collecting the semen sample.

The sample is usually collected through masturbation into a sterile container provided by the laboratory.

The patient should follow the laboratory’s instructions carefully.

Important points include:

• Follow the recommended period of sexual abstinence given by the laboratory.
• Collect the entire ejaculate whenever possible.
• Use the sterile container provided.
• Avoid using ordinary containers.
• Avoid lubricants unless the laboratory specifically provides or approves one.
• Inform the laboratory if any part of the sample was lost during collection.
• Deliver the sample within the time specified by the laboratory if collection occurs outside the laboratory.

Correct collection and handling are important because poor collection can affect the accuracy of the result.

The WHO manual provides detailed standardized procedures for semen collection, handling and laboratory examination.

How Long Should You Abstain Before a Semen Analysis?

The laboratory or doctor should provide specific instructions regarding sexual abstinence before the test.

The WHO manual provides standardized recommendations for sample collection and examination, while individual laboratories may provide practical instructions based on their testing protocol.

Patients should follow the instructions provided by the testing laboratory rather than choosing an arbitrary abstinence period.

If you have recently had a fever or significant illness, tell our doctor because illness can temporarily affect sperm production.

What Happens During the Semen Analysis?

Once our laboratory receives the sample, trained laboratory personnel examine it using standardized procedures.

The laboratory may assess:

1. Semen volume
2. Sperm concentration
3. Total sperm number
4. Sperm motility
5. Sperm morphology
6. Other findings when indicated

The WHO 6th edition provides detailed laboratory procedures and quality-control approaches designed to improve the consistency and reliability of semen examination.

Why Does Laboratory Quality Matter?

Semen analysis is not simply a matter of counting sperm.

The laboratory needs appropriate equipment, trained personnel, standardized methods and quality-control procedures.

Small differences in collection, processing and analysis can affect reported results.

For this reason, the WHO developed standardized laboratory procedures to improve the quality and comparability of semen analyses between laboratories.

When patients receive an unexpected abnormal result, doctors may consider repeating the analysis at a reliable laboratory using standardized procedures.

When Should a Man Get a Semen Analysis?

Our doctors recommend semen analysis when a couple seeks evaluation for infertility.

Current EAU guidance recommends infertility evaluation when a couple has not conceived after 12 months of regular, unprotected intercourse, while earlier assessment may be appropriate in certain clinical circumstances. The guidance also recommends evaluating both partners simultaneously.

Our doctor recommend earlier male evaluation when the man has factors such as:

• Previous infertility
• Previous testicular surgery
• Undescended testicle
• Testicular injury
• Varicocele
• Erectile or ejaculatory problems
• Previous genital infection
• Chemotherapy or radiation exposure
• Hormonal problems
• Certain genetic conditions
• Use of medications that may affect fertility

The exact timing should depend on the couple’s circumstances.

Semen Analysis as Part of a Complete Male Infertility Evaluation

Although semen analysis plays a central role, doctors should not evaluate male infertility using semen analysis alone.

A comprehensive assessment may include:

Medical history

Our doctors will ask about:

• Previous pregnancies
• Previous fertility problems
• Childhood illnesses
• Testicular conditions
• Surgeries
• Medications
• Sexual function
• Ejaculatory function
• Lifestyle
• Smoking and alcohol
• Occupational or environmental exposures
• Previous cancer treatment

Physical examination

Our doctors will examine:

• Testicles
• Epididymis
• Vas deferens
• Scrotum
• Penis
• Secondary sexual characteristics

Our doctors also assess testicular size and look for a varicocele or other abnormalities.

Hormonal tests

Our doctors recommend blood tests such as:

• Testosterone
• Follicle-stimulating hormone (FSH)
• Luteinizing hormone (LH)
• Prolactin in selected cases

The exact tests depend on the patient’s symptoms and semen results.

Ultrasound

Our doctors recommend scrotal ultrasound or other imaging when they suspect a structural abnormality.

Imaging is not automatically necessary for every man with infertility.

Genetic testing

Some men with severe sperm abnormalities or azoospermia may require genetic testing.

The decision depends on the semen findings and clinical situation.

Current EAU guidance recommends tailoring additional investigations such as genetic testing and imaging to the patient’s clinical features and semen parameters.

What Can Abnormal Semen Results Indicate?

An abnormal semen analysis can have many possible explanations.

Potential causes include:

• Varicocele
  • A varicocele refers to enlarged veins around the testicle.
  • It can affect testicular function and sperm production in some men.
• Hormonal problems
  • The brain, pituitary gland and testes work together to regulate sperm production.
  • Hormonal abnormalities can interfere with this process.
• Testicular disorders
  • Previous infection, injury, surgery or other testicular conditions can affect sperm production.
• Genetic conditions
  • Certain genetic abnormalities can affect sperm production or the male reproductive tract.
• Reproductive tract obstruction
  • A blockage can prevent sperm from reaching the ejaculate even when the testes continue producing sperm.
• Medications and medical treatments
  • Some medicines and treatments can affect sperm production.
  • Cancer treatments such as chemotherapy and radiation can have significant effects on fertility.
• Lifestyle and environmental factors
  • Smoking, excessive alcohol use, obesity, poor sleep, certain environmental exposures and other factors may negatively affect reproductive health.
  • However, lifestyle factors do not explain every abnormal semen analysis.

What If the Semen Analysis Is Normal?

A normal semen analysis is reassuring, but it does not guarantee fertility.

The EAU specifically notes that semen analysis alone cannot distinguish fertile from infertile men.

If a couple continues to experience infertility despite apparently normal semen parameters, the doctor may investigate:

• Female fertility factors
• Sexual or ejaculatory problems
• Timing and frequency of intercourse
• Hormonal abnormalities
• Anatomical problems
• Other male reproductive factors

The couple may require a broader fertility evaluation.

What If the Semen Analysis Is Abnormal?

An abnormal result does not automatically mean that the couple cannot conceive.

Our doctor may:

1. Repeat the semen analysis.
2. Review the patient’s medical and reproductive history.
3. Perform a physical examination.
4. Order hormonal tests when indicated.
5. Investigate for varicocele or obstruction.
6. Consider genetic testing in selected cases.
7. Recommend lifestyle modifications where appropriate.
8. Discuss medical or surgical treatment when a treatable cause exists.
9. Consider assisted reproductive techniques when necessary.

The next step depends on the pattern and severity of the abnormality.

Can Abnormal Semen Parameters Improve?

Sometimes. The possibility of improvement depends on the underlying cause.

For example, our doctors will be able to improve sperm parameters when an identifiable and treatable problem affects fertility.

Potentially treatable causes can include selected cases of:

• Varicocele
• Hormonal disorders
• Certain infections
• Obstruction
• Medication-related problems
• Lifestyle-related factors

However, patients should avoid products or supplements marketed as guaranteed sperm boosters.

Treatment should target the underlying cause whenever possible.

Is Semen Analysis Enough Before IVF or ICSI?

Semen analysis provides important information when doctors plan fertility treatment, but it is only one part of the decision-making process.

Our doctors consider:

• Sperm concentration
• Total sperm number
• Motility
• Morphology
• Female partner’s age and fertility factors
• Previous fertility treatment
• Duration of infertility
• Underlying causes
• Other clinical factors

Depending on the circumstances, the fertility team may recommend treatments such as:

• Timed intercourse
• Ovulation-related treatment for the female partner
• Intrauterine insemination (IUI)
• In-vitro fertilization (IVF)
• Intracytoplasmic sperm injection (ICSI)
• Surgical sperm retrieval
• Other fertility treatments

A low sperm count does not automatically mean that IVF or ICSI is necessary.

What Is Azoospermia?

Azoospermia means that no sperm are detected in the ejaculate after appropriate laboratory examination.

Our doctors then need to determine why sperm are absent.

The two broad categories include:

Obstructive azoospermia

The testes may produce sperm, but an obstruction prevents sperm from reaching the ejaculate.

Non-obstructive azoospermia

The testes have significantly impaired sperm production.

Further evaluation can include hormonal testing, physical examination, genetic testing and imaging when appropriate.

In selected men, our doctors retrieve sperm directly from the epididymis or testicle for use with assisted reproductive techniques.

Can Semen Analysis Detect Infection?

Semen analysis may identify findings that prompt further evaluation, but a routine semen analysis is not a universal infection test.

Depending on the patient’s symptoms and findings, doctors may recommend additional testing.

The WHO 6th edition includes information on markers for infection and expanded approaches to semen examination, but the appropriate infection work-up depends on the clinical situation.

What Are Advanced Semen Tests?

Some men may require additional testing beyond routine semen analysis.

Depending on the clinical situation, doctors may consider:

• Sperm vitality testing
• Specialized sperm-function tests
• Sperm DNA fragmentation testing
• Genetic testing
• Hormonal evaluation
• Other laboratory investigations

These tests do not belong in every initial infertility evaluation.

For example, current EAU guidance does not recommend routine reactive oxygen species testing and reserves sperm DNA fragmentation testing for selected situations such as recurrent pregnancy loss from natural conception, failure of assisted reproductive treatment or unexplained infertility.

Our doctors therefore order advanced tests selectively rather than using them routinely for every patient.

Common Mistakes That Can Affect Semen Analysis

Patients can improve the reliability of the test by following laboratory instructions carefully.

Common problems include:

• Not collecting the complete sample
• Using an unsuitable container
• Using unapproved lubricants
• Delaying delivery beyond the laboratory’s recommended time
• Not informing the laboratory about sample loss
• Not following the recommended abstinence instructions
• Testing shortly after a significant illness without informing the doctor

Always follow the laboratory’s collection instructions.

Myths about Semen Analysis and Male Infertility

Myth 1: A low sperm count means permanent infertility.

Fact: A low sperm count can have different causes, and some are treatable. Doctors may repeat the test and investigate the underlying cause.

Myth 2: A normal semen analysis guarantees fertility.

Fact: Semen analysis cannot guarantee fertility. Doctors must consider the entire couple and other fertility factors.

Myth 3: One semen analysis is always enough.

Fact: Doctors may repeat the test when the first analysis is abnormal. Current EAU guidance recommends at least two consecutive analyses when the baseline result is abnormal.

Myth 4: Only sperm count matters.

Fact: Doctors also consider semen volume, total sperm number, motility, morphology and other findings.

Myth 5: Male infertility means there is nothing that can be treated.

Fact: Some causes of male infertility can be treated medically or surgically, while others may require assisted reproductive techniques.

Myth 6: Fertility problems are always caused by the woman.

Fact: Male factors contribute to infertility in a substantial proportion of couples. Both partners should receive appropriate evaluation.

When Should You Consult a Doctor?

You should consider a fertility evaluation if:

• You and your partner have been trying to conceive for 12 months without success.
• Your partner is older or has known fertility concerns.
• You have previously experienced infertility.
• You have a history of testicular problems.
• You have undergone chemotherapy or radiation.
• You have erectile or ejaculation problems.
• You have a known varicocele.
• You have had previous reproductive surgery.
• You have concerns about sperm production.

Do not wait unnecessarily when you already know about a potential fertility problem.

Early evaluation can help identify treatable causes and prevent delays in appropriate treatment.

How Jyoti Hospital Can Help With Male Infertility Evaluation

At Jyoti Hospital, Gurugram, our doctors can approach male infertility as part of a comprehensive couple-based fertility evaluation.

Semen analysis can provide important initial information about sperm production and function. However, the team can look beyond the report when necessary.

Depending on the patient’s situation, evaluation may include:

• Detailed medical and reproductive history
• Physical examination
• Semen analysis
• Repeat semen analysis when indicated
• Hormonal evaluation
• Assessment for varicocele
• Imaging when clinically appropriate
• Evaluation for obstructive causes
• Genetic testing in selected patients
• Discussion of fertility treatment options

The goal is not simply to label a semen report as “normal” or “abnormal.”

Instead, our doctors aim to understand why a semen abnormality may be present and how it affects the couple’s fertility plan.

If the semen analysis shows an abnormality, our doctor will explain what it means, whether further testing is required and which treatment options may be appropriate.

Final Thoughts

Semen analysis plays a central role in the evaluation of male infertility. It provides important information about semen volume, sperm concentration, total sperm number, motility and morphology and can help doctors decide whether further investigation is necessary.

However, patients should not treat the report as a simple fertility score.

A single abnormal result does not automatically mean permanent infertility, and a normal report does not guarantee that a couple will conceive. Doctors need to consider the male partner’s medical and reproductive history, physical findings and other investigations while evaluating both partners.

The WHO 6th edition semen manual provides standardized laboratory methods to improve the quality and consistency of semen examination, while current male-infertility guidelines emphasize semen analysis as an important component of a broader male reproductive evaluation.

If you and your partner are experiencing difficulty conceiving, an appropriately performed semen analysis can provide an important starting point for understanding male reproductive health and planning the next steps.

At Jyoti Hospital, Gurugram, a comprehensive evaluation can help identify potential causes of male infertility and guide you toward appropriate management or fertility treatment.
