Having difficulty conceiving can be emotionally challenging for both partners. Although fertility is often associated primarily with women, male factors contribute to infertility in a substantial proportion of couples.

Male infertility refers to a man’s reduced ability to contribute to conception. It can occur because the testicles produce too few sperm, sperm do not function properly, sperm cannot reach the semen, or other reproductive, hormonal, sexual or medical problems interfere with conception.

Importantly, infertility is a couple’s health issue. A problem in the male partner may contribute to difficulty conceiving, but doctors should evaluate both partners rather than assuming that infertility comes from one person.

At Jyoti Hospital, Gurugram, our urology team can evaluate men who have difficulty conceiving and identify potentially treatable causes. Depending on the findings, treatment may include lifestyle changes, medicines for selected conditions, treatment of varicocele or obstruction, surgical procedures, sperm-retrieval techniques or assisted reproductive methods.

What Is Male Infertility?

Male infertility means that a man has a reduced ability to contribute to conception.

Our doctors generally consider infertility when a couple has regular unprotected sexual intercourse without achieving pregnancy over an appropriate period. The exact evaluation pathway can vary according to the couple’s age, medical history and individual circumstances.

Male infertility can result from problems involving:

• Sperm production
• Sperm count
• Sperm movement
• Sperm shape and function
• Sperm transport
• Hormonal regulation
• Testicular function
• Ejaculation
• Sexual function
• Genetic factors
• Previous infections, injuries or surgeries

Some men have more than one contributing factor.

A man can also have no obvious symptoms apart from difficulty achieving pregnancy.

How Common Is Male Factor Infertility?

Infertility affects couples worldwide and can result from male factors, female factors, a combination of both, or sometimes no clearly identifiable cause.

For this reason, doctors should evaluate both partners rather than automatically attributing infertility to the woman.

A semen analysis provides important information about the male partner, but it cannot independently confirm whether a man is fertile or infertile. The WHO emphasizes that fertility depends on multiple factors affecting both partners.

What Causes Male Infertility?

Male infertility can develop because of problems with sperm production, sperm transport, hormones, sexual function or the reproductive organs.

Some causes are reversible or treatable, while others may require assisted reproductive techniques.

1. Problems With Sperm Production

The testicles produce sperm through a complex process called spermatogenesis.

Several conditions can interfere with this process, including:

• Testicular disorders
• Genetic abnormalities
• Hormonal disorders
• Infections
• Previous testicular injury
• Exposure to certain medicines or toxins
• Excessive heat exposure
• Chemotherapy or radiation
• Certain chronic illnesses

These problems can reduce sperm production or result in poor sperm quality.

2. Varicocele

A varicocele is an enlargement of veins around the testicle.

It resembles varicose veins and commonly develops on one side, although it can affect both sides.

Some men with varicocele have no symptoms. Others may experience:

• A dragging or aching sensation
• Scrotal discomfort
• Visible or enlarged veins
• Testicular size differences
• Abnormal semen parameters

Varicocele can affect testicular function in some men and may contribute to infertility.

However, not every varicocele requires treatment.

Our doctors consider factors such as physical examination findings, semen analysis, symptoms, testicular size and the couple’s fertility situation before recommending treatment.

3. Hormonal Problems

Sperm production depends on a carefully regulated hormonal system involving the:

• Hypothalamus
• Pituitary gland
• Testicles

Problems affecting this system can reduce sperm production.

Possible causes include:

• Pituitary disorders
• Low or abnormal gonadotropin production
• Certain thyroid disorders
• High prolactin levels
• Other endocrine conditions

Hormonal evaluation becomes particularly important when semen analysis shows very low sperm production or when the patient has symptoms suggesting a hormonal disorder.

4. Testosterone Problems

Testosterone plays an important role in male sexual health, but taking testosterone does not treat male infertility.

In fact, external testosterone can suppress the hormonal signals that stimulate sperm production and may significantly reduce sperm production.

Men who are trying to conceive should therefore not start testosterone replacement therapy without discussing fertility with a qualified doctor.

If low testosterone and infertility occur together, doctors can investigate the underlying cause and consider fertility-preserving treatment when appropriate.

5. Blockage of the Reproductive Tract

Sperm must travel from the testicles through a series of ducts before leaving the body during ejaculation.

A blockage can prevent sperm from reaching the semen.

Possible causes include:

• Previous infections
• Surgery
• Injury
• Congenital abnormalities
• Scarring
• Previous vasectomy

A man may continue to produce sperm normally inside the testicles while having very few or no sperm in the semen because of an obstruction.

This condition is called obstructive azoospermia.

6. Infections

Certain infections can affect the male reproductive system and potentially interfere with fertility.

Depending on the infection, inflammation or scarring may affect sperm production or sperm transport.

Examples can include infections involving:

• Testicles
• Epididymis
• Prostate
• Seminal tract

Our doctors may investigate infection when symptoms, examination findings or medical history suggest it.

7. Genetic Causes

Genetic factors can affect sperm production, testicular development or the structure of the reproductive tract.

These genetic factors become particularly important in men with:

• Severe reduction in sperm count
• Very low sperm production
• Azoospermia
• Certain testicular abnormalities
• Specific physical findings

Depending on the clinical situation, doctors may recommend genetic testing.

Genetic counselling can also become important when a genetic abnormality may affect reproductive planning or could potentially be passed to a child.

8. Testicular Injury

The testicles are vulnerable to trauma.

Significant injury can affect sperm production, particularly if it damages testicular tissue.

Previous surgery or treatment involving the testicles can also influence fertility.

Tell our doctor about any history of:

• Testicular trauma
• Testicular surgery
• Hernia surgery
• Testicular torsion
• Undescended testicle
• Cancer treatment

9. Undescended Testicle

Normally, the testicles descend into the scrotum before birth.

An undescended testicle can affect future fertility, particularly when the condition remains untreated.

Men who had an undescended testicle during childhood may have an increased risk of reduced sperm production later in life.

10. Medicines and Medical Treatments

Some medicines and treatments can affect sperm production or sexual function.

These may include:

• Testosterone and anabolic steroids
• Certain chemotherapy medicines
• Some hormonal medicines
• Certain other prescription drugs

Cancer treatments such as chemotherapy and radiation can significantly affect fertility.

Men who may undergo fertility-affecting treatment should discuss sperm banking or fertility preservation with their healthcare team before treatment whenever appropriate.

11. Lifestyle and Environmental Factors

Several lifestyle and environmental factors may negatively affect reproductive health.

These can include:

• Smoking
• Excessive alcohol consumption
• Recreational drug use
• Anabolic steroid use
• Obesity
• Poor diet
• Physical inactivity
• Severe psychological stress
• Sleep problems
• Exposure to certain chemicals
• Excessive heat exposure

Not every lifestyle factor causes infertility by itself, but improving overall health can support reproductive health and may benefit men who are trying to conceive.

Can Stress Cause Male Infertility?

Psychological stress does not always directly cause infertility, but significant stress can affect several factors related to conception.

For example, stress may contribute to:

• Reduced sexual desire
• Erectile difficulties
• Ejaculatory problems
• Poor sleep
• Unhealthy lifestyle habits

These factors can make conception more difficult.

If stress, anxiety or relationship difficulties are affecting sexual function or fertility, addressing them forms an important part of comprehensive care.

What Are the Symptoms of Male Infertility?

Male infertility often has no obvious symptoms.

A man may feel completely healthy and still have an abnormal semen analysis.

The most obvious sign is: Difficulty achieving pregnancy despite regular unprotected sexual intercourse.

Some men may also experience symptoms that suggest an underlying cause, such as:

• Erectile difficulties
• Reduced sexual desire
• Ejaculation problems
• Testicular pain
• Testicular swelling
• A lump in the scrotum
• Small or asymmetrical testicles
• Reduced facial or body hair
• Breast enlargement
• Symptoms of hormonal problems

If these symptoms occur alongside difficulty conceiving, a medical evaluation becomes particularly important.

When Should a Man Seek an Infertility Evaluation?

A couple should not necessarily wait for years before seeking medical advice.

The appropriate timing depends on factors such as the female partner’s age, duration of attempts to conceive, previous pregnancies and medical history.

Men should consider earlier evaluation when they have:

• Previous testicular surgery
• Testicular trauma
• Undescended testicle
• Varicocele
• Previous chemotherapy or radiation
• Sexual or ejaculation problems
• Previous infertility
• Known hormonal disorders
• Recurrent genital infections
• A history of vasectomy
• Other conditions that may affect fertility

At Jyoti Hospital, our urology team can evaluate these factors and determine the appropriate next steps.

How Is Male Infertility Diagnosed?

Doctors usually begin with a detailed medical and reproductive history followed by a physical examination.

The evaluation may include:

• Medical history
• Sexual history
• Reproductive history
• Medication review
• Lifestyle assessment
• Physical examination
• Semen analysis
• Hormonal testing when indicated
• Scrotal ultrasound in selected cases
• Genetic testing in selected patients
• Additional investigations based on the findings

The evaluation should remain individualised rather than giving every patient the same set of tests.

What Is a Semen Analysis?

A semen analysis is one of the most important initial tests in male infertility.

It evaluates characteristics of the semen and sperm, which may include:

• Semen volume
• Sperm concentration
• Total sperm number
• Sperm motility
• Sperm morphology
• Other semen characteristics

The WHO’s sixth edition laboratory manual provides standardized methods for semen examination and processing and emphasizes quality control and standardized laboratory procedures.

However, a semen analysis does not by itself determine whether a man is fertile or infertile.

Semen parameters can vary between samples, and fertility depends on several factors involving both partners.

Does One Abnormal Semen Analysis Mean Infertility?

Not necessarily. Semen parameters can vary over time.

If a semen analysis produces abnormal results, our doctor may recommend repeating the test under appropriate laboratory conditions.

Doctors then interpret the results alongside:

• Medical history
• Physical examination
• Previous fertility
• Partner’s fertility evaluation
• Other test results

This approach provides a more meaningful assessment than focusing on a single number.

What Do Sperm Count, Motility and Morphology Mean?

Sperm Count

Sperm count refers to the number of sperm present in a semen sample.

A lower sperm concentration can reduce the probability of conception, although sperm count alone does not determine fertility.

Sperm Motility

Motility describes how sperm move.

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

Sperm Morphology

Morphology describes the size and shape of sperm.

A semen report may describe the percentage of sperm with normal morphology.

Our doctors interpret morphology alongside other semen parameters rather than using it as an isolated measure of fertility.

What Is Azoospermia?

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

It does not necessarily mean that the testicles produce no sperm.

Our doctors broadly consider two important categories:

Obstructive Azoospermia

The testicles may produce sperm, but a blockage prevents sperm from reaching the semen.

Non-Obstructive Azoospermia

The testicles produce very little or no sperm because of impaired sperm production.

The distinction matters because treatment options differ.

Some men with azoospermia may still have sperm that doctors can retrieve directly from the testicle or epididymis for use in assisted reproduction.

What Is Oligospermia?

Oligospermia refers to a lower-than-expected sperm concentration.

The severity can vary.

Some men with mildly reduced sperm concentration may conceive naturally, while severe abnormalities may require more extensive evaluation or assisted reproductive treatment.

Our doctors interpret semen results using appropriate laboratory reference standards rather than assuming that one parameter alone predicts fertility.

What Blood Tests Are Used in Male Infertility?

Our doctors may recommend hormonal testing when semen analysis or clinical findings suggest an endocrine problem.

Depending on the situation, tests may include:

• Follicle-stimulating hormone (FSH)
• Luteinizing hormone (LH)
• Testosterone
• Prolactin
• Thyroid-related tests
• Other hormonal investigations when appropriate

Not every man needs every hormone test.

Our doctors select investigations based on symptoms, examination findings and semen-analysis results.

What Is the Role of Scrotal Ultrasound?

A scrotal ultrasound can help our doctors evaluate the testicles and surrounding structures.

It may help identify:

• Varicocele
• Testicular masses
• Testicular size differences
• Certain structural abnormalities
• Other scrotal conditions

Our doctors do not necessarily require an ultrasound for every man with infertility. They recommend it when clinical findings or the medical history make imaging appropriate.

When Is Genetic Testing Needed?

Our doctors may consider genetic testing in men with severe sperm-production problems, particularly when sperm counts are extremely low or absent.

Depending on the clinical situation, testing may include:

• Karyotyping
• Y-chromosome microdeletion testing
• CFTR-related testing in selected men with suspected congenital absence of the vas deferens

The exact tests depend on the clinical findings.

Genetic counselling can help explain the results and their potential implications for assisted reproduction and offspring.

How Is Male Infertility Treated?

Treatment depends entirely on the underlying cause.

Our doctors use:

• Lifestyle modification
• Medical treatment
• Hormonal treatment for selected endocrine disorders
• Varicocele treatment
• Surgery for certain obstructions
• Sperm-retrieval procedures
• Assisted reproductive techniques
• Fertility preservation

The goal is not simply to improve a semen report. The goal is to help the couple achieve pregnancy safely and efficiently while addressing any underlying medical problem.

Treatment for Hormonal Male Infertility

Some hormonal disorders can interfere with sperm production.

When infertility results from a specific hormonal deficiency, doctors may use hormone-based treatment to stimulate the body’s own sperm production.

Treatment depends on the underlying disorder.

This is different from giving testosterone replacement.

Testosterone replacement can suppress sperm production and should not be used as a fertility treatment.

Men who have low testosterone and are trying to conceive should discuss fertility-preserving options with a qualified urologist or reproductive specialist.

Treatment for Varicocele

Not every varicocele requires treatment.

Our doctors consider varicocele repair when appropriate, particularly when there is:

• A clinically significant varicocele
• Abnormal semen parameters
• Otherwise unexplained infertility
• Appropriate reproductive circumstances

Treatment can involve surgical repair or microsurgical techniques.

The decision should remain individualised after evaluation of both partners.

Treatment for Obstructive Infertility

If sperm production remains intact but a blockage prevents sperm from reaching the semen, doctors may consider:

• Surgical reconstruction
• Microsurgical procedures
• Sperm retrieval
• Assisted reproduction

The best approach depends on the location and cause of the obstruction, the couple’s fertility goals and the female partner’s reproductive factors.

What Is Sperm Retrieval?

Some men have no sperm in the ejaculate but still produce sperm within the testicles.

Our doctors retrieve sperm directly from the reproductive tract or testicular tissue using techniques such as:

• Percutaneous epididymal sperm aspiration
• Testicular sperm aspiration
• Testicular sperm extraction
• Microsurgical testicular sperm extraction in selected cases

The appropriate technique depends on whether the patient has obstructive or non-obstructive azoospermia and other clinical factors.

Retrieved sperm can sometimes be used with intracytoplasmic sperm injection (ICSI) as part of assisted reproduction.

What Are IVF and ICSI?

In Vitro Fertilisation (IVF)

IVF involves fertilising an egg with sperm in a laboratory and subsequently transferring an embryo into the uterus.

Intracytoplasmic Sperm Injection (ICSI)

ICSI involves injecting a single sperm directly into an egg.

Our doctors consider ICSI when male-factor infertility significantly affects the likelihood of fertilisation, including situations where only a small number of sperm are available.

Assisted reproductive treatment should be selected according to the couple’s specific circumstances rather than automatically using IVF or ICSI for every male infertility case.

Can Male Infertility Be Treated Without Surgery?

Yes, depending on the cause.

Some men may benefit from:

• Treatment of hormonal disorders
• Management of infections when present
• Medication changes
• Lifestyle modifications
• Treatment of erectile or ejaculatory disorders
• Fertility-preserving hormonal therapy in selected conditions

However, some causes require surgery or sperm retrieval.

The treatment plan should therefore begin with identifying the underlying cause.

Can Lifestyle Changes Improve Male Fertility?

Lifestyle changes can support overall reproductive health and may improve some fertility-related factors.

Consider:

• Maintain a Healthy Weight
  • Excess body weight can affect hormonal balance and reproductive health.
• Exercise Regularly
  • Moderate physical activity supports cardiovascular and metabolic health.
  • Avoid excessive training that leads to exhaustion, poor nutrition or hormonal disturbances.
• Stop Smoking
  • Smoking can negatively affect overall health and may adversely affect sperm quality.
• Limit Alcohol
  • Excessive alcohol consumption can negatively affect reproductive and general health.
• Avoid Recreational Drugs
  • Some recreational drugs can interfere with reproductive function.
• Avoid Anabolic Steroids
  • Anabolic steroids can suppress natural testosterone production and sperm production.
• Eat a Balanced Diet
  • Prioritise:
    • Fruits
    • Vegetables
    • Whole grains
    • Protein
    • Healthy fats
    • Nuts and seeds
    • Adequate micronutrients
• Sleep Well
  • Consistent, adequate sleep supports overall hormonal and metabolic health.
• Manage Stress
  • Long-term stress can affect sexual function, sleep and lifestyle habits.

Does Heat Affect Sperm Production?

The testicles function best at a temperature slightly below core body temperature.

Excessive or prolonged heat exposure may affect sperm production in some men.

If you are undergoing fertility evaluation, discuss occupational or lifestyle exposures involving substantial heat with our doctor.

However, do not assume that every exposure to warmth causes infertility.

Our doctors consider the overall clinical picture.

Can Tight Underwear Cause Infertility?

There is no strong basis for telling every man that tight underwear causes infertility.

Temperature can influence sperm production, but everyday clothing choices alone are not usually the primary cause of male infertility.

Men should focus on established health factors such as smoking, anabolic steroid use, excessive alcohol consumption, obesity, medical conditions and appropriate treatment of reproductive disorders.

Can Masturbation Cause Male Infertility?

No. Normal masturbation does not cause permanent male infertility.

Frequent ejaculation may temporarily alter semen volume or sperm concentration in a particular sample, but it does not generally cause permanent infertility.

If you are undergoing semen analysis, follow the laboratory’s instructions regarding the recommended period of abstinence before providing the sample.

Does Erectile Dysfunction Cause Male Infertility?

Erectile dysfunction and infertility are different conditions, although they can occur together.

A man with erectile dysfunction may have difficulty having intercourse sufficient for conception.

However, a man can have normal erections and still have severe sperm abnormalities.

Similarly, some men with infertility have normal sexual function.

Our doctors therefore evaluate sexual function and reproductive function separately while considering how they interact.

Does Age Affect Male Fertility?

Male fertility can change with age.

As men grow older, some semen parameters may change and certain reproductive risks can increase.

However, men do not experience an abrupt end to fertility comparable to menopause.

Age should therefore be considered as one part of an overall fertility assessment.

Male Infertility and Cancer Treatment

Cancer treatment can affect sperm production.

Chemotherapy, radiation and some surgeries can damage reproductive function.

Men who have been diagnosed with cancer and may undergo fertility-affecting treatment should discuss fertility preservation before treatment begins whenever possible.

Sperm cryopreservation can provide an opportunity to preserve reproductive potential for future use.

What Is Sperm Freezing?

Sperm cryopreservation, commonly called sperm freezing, stores sperm at extremely low temperatures for potential future use.

Our doctors recommend sperm banking before:

• Chemotherapy
• Radiation
• Certain testicular surgeries
• Treatments likely to affect sperm production
• Some fertility-related procedures

Men may also consider sperm preservation in selected personal or medical circumstances.

Can Male Infertility Be Prevented?

Not every cause of male infertility can be prevented.

Genetic conditions, congenital abnormalities and some medical disorders cannot always be avoided.

However, you can support reproductive health by:

• Avoiding anabolic steroids
• Avoiding smoking
• Limiting excessive alcohol
• Maintaining a healthy body weight
• Exercising regularly
• Eating a balanced diet
• Managing chronic diseases
• Treating reproductive infections appropriately
• Avoiding unnecessary exposure to reproductive toxins
• Protecting the testicles from significant injury
• Discussing fertility preservation before cancer treatment

Early medical evaluation can also help identify potentially treatable causes.

When Should You See a Urologist?

You should consider a fertility evaluation if:

• You and your partner have been trying to conceive without success
• You have had a previous fertility problem
• You have a history of undescended testicle
• You have had testicular surgery or trauma
• You have a known or suspected varicocele
• You have experienced recurrent genital infections
• You have sexual or ejaculation problems
• You have used anabolic steroids or testosterone
• You have undergone chemotherapy or radiation
• You have very low or absent sperm on a previous semen analysis
• You have concerns about your fertility

You do not need to feel embarrassed about seeking help. Male infertility is a medical condition, and many causes can be investigated and treated.

How Jyoti Hospital Can Help With Male Infertility

At Jyoti Hospital, Gurugram, our urology team takes a structured approach to evaluating male infertility.

Depending on your history and examination, your evaluation may include:

• Detailed medical and reproductive history
• Sexual and ejaculation assessment
• Physical examination
• Semen analysis
• Hormonal evaluation when indicated
• Scrotal examination
• Ultrasound when clinically appropriate
• Evaluation for varicocele
• Assessment for obstruction
• Genetic testing in selected cases
• Evaluation of lifestyle and medication-related factors

Once we identify the likely cause, our team can discuss appropriate treatment options.

Depending on the situation, treatment may involve medical management, correction of an underlying condition, varicocele treatment, surgery, sperm retrieval or referral for assisted reproductive techniques.

Most importantly, we recognise that infertility affects both partners. Appropriate coordination with the female partner’s fertility evaluation can help the couple choose the most suitable treatment pathway.

Final Thoughts

Male infertility can result from problems involving sperm production, sperm quality, hormones, reproductive-tract function, sexual function or other medical conditions.

Because many men experience no symptoms, difficulty achieving pregnancy may be the first indication of an underlying reproductive problem.

The evaluation usually begins with a detailed medical history, physical examination and semen analysis. Doctors may then recommend hormonal tests, ultrasound, genetic testing or other investigations depending on the findings.

Treatment depends on the underlying cause. Some men benefit from lifestyle changes or medical treatment, while others may require varicocele repair, treatment of an obstruction, sperm retrieval or assisted reproductive techniques such as IVF or ICSI.

Importantly, male infertility is not the same as permanent sterility. Many causes can be treated, managed or overcome with appropriate fertility treatment.

At Jyoti Hospital, Gurugram, our urology team can help evaluate male infertility, identify potentially treatable causes and guide couples toward an appropriate treatment pathway.

If you and your partner are having difficulty conceiving, seeking medical advice early can help you understand the cause and avoid unnecessary delays.
