Male Infertility

Comprehensive Evaluation and Personalised Care for Male Fertility

Male infertility is a condition in which factors related to a man’s reproductive health reduce the likelihood of achieving a pregnancy with his partner. It may be associated with low sperm production, poor sperm movement, abnormal sperm shape, blockages in the reproductive tract, hormonal imbalances, or difficulties with sexual function.

Infertility is a shared reproductive health concern, and male factors contribute to some or all of the difficulty conceiving in a substantial proportion of couples. It is important to evaluate both partners rather than assuming the problem lies with one person.

At Dr. Amarjeet’s gynaecology practice, fertility assessment can help couples understand possible contributing factors, explore appropriate investigations, and plan the next steps in their journey towards parenthood.

What Is Male Infertility?

Male infertility refers to reduced reproductive potential due to problems affecting sperm production, sperm function, sperm transport, or ejaculation.

Healthy male fertility depends on several processes working together:

  • The testes must produce sperm.

  • The body must produce appropriate reproductive hormones.

  • Sperm must mature and develop the ability to move.

  • The reproductive ducts must allow sperm to travel into the semen.

  • Ejaculation must deliver semen into the female reproductive tract.

  • Sperm must be able to reach and fertilise an egg.

A problem at any stage can affect fertility. However, an abnormal test result does not automatically mean that natural conception is impossible. Many contributing factors can be managed, and assisted reproductive techniques may offer additional options.

What Are the Signs and Symptoms of Male Infertility?

Male infertility often has no obvious symptoms. Many men discover a possible fertility concern only when a couple has difficulty conceiving.

Depending on the underlying cause, possible signs may include:

  • Difficulty achieving a pregnancy after regular, unprotected intercourse

  • Reduced sexual desire

  • Difficulty achieving or maintaining an erection

  • Problems with ejaculation

  • Pain, swelling, or a lump in the testicle

  • A history of undescended testicles or testicular injury

  • Previous infections or surgery involving the reproductive system

  • Symptoms associated with hormonal imbalance, such as reduced facial hair or changes in muscle mass

These symptoms do not necessarily indicate infertility, but they may warrant medical assessment. Sudden, severe testicular pain requires urgent medical attention.

Common Causes of Male Infertility

Male infertility can result from several medical, hormonal, genetic, structural, and lifestyle-related factors. In some cases, more than one factor may be present.

1. Low Sperm Count

Low sperm count, also called oligozoospermia, means the semen contains fewer sperm than expected.

A lower sperm count may reduce the likelihood of sperm reaching and fertilising an egg. Possible causes include hormonal problems, varicocele, certain infections, genetic conditions, testicular damage, and exposure to specific medicines or toxins.

The significance of a low sperm count depends on the complete semen analysis and the couple’s overall fertility assessment.

2. Poor Sperm Motility

Sperm motility refers to the ability of sperm to move effectively. Progressive movement is important because sperm need to travel through the female reproductive tract to reach the egg.

Reduced motility, known as asthenozoospermia, may be associated with infections, varicocele, oxidative stress, certain medical conditions, or other factors. A semen analysis helps assess sperm movement.

3. Abnormal Sperm Morphology

Sperm morphology describes the size and shape of sperm. Changes in sperm shape may affect the ability of sperm to function normally.

An abnormal morphology result should not be interpreted in isolation. Fertility depends on multiple semen parameters and other factors, and a morphology result alone cannot reliably predict whether natural conception will occur.

4. Varicocele

A varicocele is an enlargement of veins within the scrotum, similar to varicose veins. It can increase the temperature around the testicles and may affect sperm production or function in some men.

Not every varicocele causes infertility or requires treatment. A specialist may recommend treatment in selected cases, particularly when there are fertility concerns and abnormal semen parameters.

5. Hormonal Imbalances

Hormones such as follicle-stimulating hormone (FSH), luteinising hormone (LH), and testosterone play important roles in sperm production and sexual function.

Hormonal disorders may affect sperm production, libido, erections, or other aspects of reproductive health. Evaluation can help identify whether a hormonal condition is contributing to infertility.

6. Blockages in the Reproductive Tract

Blockages in the tubes that transport sperm may prevent sperm from entering the semen. These may occur due to previous infections, surgery, injury, congenital conditions, or other causes.

A man may produce sperm normally but have very few or no sperm in the semen because of an obstruction. Further testing may help distinguish obstructive causes from problems with sperm production.

7. Genetic Conditions

Certain genetic conditions can affect testicular development, sperm production, or the reproductive ducts.

Genetic evaluation may be considered when sperm counts are extremely low or sperm are absent from the semen, depending on the clinical findings. The results can guide treatment planning and help identify possible implications for offspring.

8. Infections and Inflammation

Some infections affecting the reproductive tract may contribute to inflammation, obstruction, or changes in semen quality. Sexually transmitted infections may also affect reproductive health.

Testing and treatment depend on the suspected infection and clinical findings. Antibiotics are not routinely beneficial for every abnormal semen result and should be used when medically indicated.

9. Erectile or Ejaculatory Problems

Difficulty achieving an erection, premature or delayed ejaculation, or an inability to ejaculate into the vagina can make conception more difficult even when sperm production is normal.

These concerns may have physical, hormonal, medication-related, or psychological causes. Many can be evaluated and treated with appropriate medical support.

10. Lifestyle and Environmental Factors

Certain lifestyle and environmental factors may affect sperm quality and reproductive health, including:

  • Smoking and tobacco use

  • Heavy alcohol consumption

  • Anabolic steroids or non-prescribed testosterone use

  • Recreational drug use

  • Obesity and metabolic health problems

  • Significant heat exposure to the testes

  • Exposure to certain workplace chemicals, pesticides, or heavy metals

  • Poorly controlled chronic medical conditions

  • Certain prescription medicines or cancer treatments

The impact varies between individuals. Reviewing these factors with a healthcare professional can help identify changes that may support fertility.

How Is Male Infertility Diagnosed?

Male infertility assessment usually begins with a medical history, physical examination, and semen analysis. Further tests are selected according to the results and any suspected underlying cause.

1. Medical and Reproductive History

The clinician may ask about:

  • How long the couple has been trying to conceive

  • Previous pregnancies with the current or previous partner

  • Previous testicular conditions, injuries, infections, or surgeries

  • Sexual function and ejaculation

  • Medicines, supplements, testosterone, or steroid use

  • Lifestyle habits and workplace exposures

  • Family history of reproductive or genetic conditions

A confidential, respectful consultation helps identify relevant factors and determine which investigations may be needed.

2. Semen Analysis

Semen analysis is one of the most important initial investigations for male fertility. A laboratory examines a semen sample to assess several parameters.

These commonly include:

  • Semen volume: The amount of fluid in the sample.

  • Sperm concentration: The number of sperm per unit of semen.

  • Total sperm number: The total number of sperm in the sample.

  • Sperm motility: The proportion of sperm that move, including progressive movement.

  • Sperm morphology: The proportion of sperm with typical shape.

  • Other findings: Depending on the laboratory, these may include pH or signs of inflammation.

Semen parameters can vary from one sample to another. If the initial result is abnormal, a repeat analysis may be recommended under appropriate collection conditions.

A semen analysis provides useful information, but no single parameter can fully determine a man’s fertility.

3. Physical Examination

A clinician may examine the testes, epididymides, and other reproductive structures to look for signs such as varicocele, testicular abnormalities, or possible obstruction.

The examination is guided by the patient’s history and initial test results.

4. Hormonal Blood Tests

Hormonal tests may be recommended when sperm production is significantly reduced, sperm are absent, sexual symptoms are present, or a hormonal condition is suspected.

Depending on the situation, tests may include testosterone, FSH, LH, and other hormones when indicated.

5. Genetic Testing

Genetic tests may be advised for selected men with severe sperm production problems or absent sperm in the semen. The exact tests depend on the clinical findings and relevant medical guidelines.

Genetic counselling may be helpful when an inherited condition is identified or suspected.

6. Imaging and Additional Investigations

Scrotal ultrasound, specialised reproductive imaging, or other investigations may be recommended when examination findings suggest a structural problem.

Additional tests may be appropriate in selected cases, such as suspected obstruction or ejaculatory dysfunction. These investigations are not necessary for every patient.

Treatment Options for Male Infertility

Treatment depends on the underlying cause, the severity of the fertility problem, the health of both partners, and the couple’s reproductive goals.

1. Lifestyle Modification

Lifestyle changes may support reproductive health, particularly when modifiable risk factors are present.

Helpful measures may include:

  • Stopping smoking and tobacco use

  • Avoiding anabolic steroids and non-prescribed testosterone

  • Limiting alcohol and avoiding recreational drugs

  • Maintaining a healthy weight

  • Eating a balanced diet with adequate nutrients

  • Exercising regularly and getting sufficient sleep

  • Managing chronic conditions with medical support

  • Reducing avoidable exposure to reproductive toxins

Sperm development takes approximately three months, so improvements in some semen parameters may take time. Lifestyle changes cannot correct every cause of infertility.

2. Medical Treatment

Medical treatment may be appropriate for specific underlying conditions, such as certain hormonal disorders or confirmed infections.

The treatment must be selected according to the diagnosis. Taking supplements, antibiotics, or hormonal medicines without medical guidance may be ineffective or harmful.

3. Hormonal Treatment

In selected men, specialist-directed hormonal treatment can help when a specific hormonal disorder is affecting sperm production.

Important: Testosterone replacement therapy can suppress sperm production and may cause a marked reduction or complete absence of sperm in the semen. Men who wish to conceive should discuss fertility-preserving alternatives with a specialist before starting testosterone or anabolic steroids.

4. Varicocele Treatment

Surgical or other specialist treatment of a varicocele may be considered in selected men with infertility and abnormal semen parameters. The decision depends on the clinical examination, fertility history, and the expected benefits and risks.

Treatment is not routinely required for every varicocele.

5. Surgical Treatment for Obstruction

When sperm transport is blocked, surgery may sometimes repair the obstruction or allow sperm to be retrieved for assisted reproduction.

The appropriate approach depends on the location and cause of the blockage, the condition of the reproductive structures, and the couple’s fertility goals.

6. Sperm Retrieval Techniques

When sperm are absent from the ejaculate, specialists may sometimes retrieve sperm directly from the epididymis or testicle.

This may be considered for selected obstructive or non-obstructive causes of azoospermia. Success depends on the underlying condition and the procedure used.

7. Assisted Reproductive Techniques

If natural conception is unlikely or previous treatment has not been successful, assisted reproductive techniques may be considered.

Intrauterine Insemination (IUI): Prepared sperm are placed inside the uterus around the time of ovulation. IUI may be appropriate in selected cases with sufficient usable sperm and other favourable fertility factors.

In Vitro Fertilisation (IVF): Eggs are collected and fertilised with sperm in a laboratory. An embryo may then be transferred into the uterus.

Intracytoplasmic Sperm Injection (ICSI): A single sperm is injected directly into an egg during IVF. ICSI is often considered in cases of significant male-factor infertility or when surgically retrieved sperm are used.

The most appropriate method depends on semen findings, the female partner’s age and reproductive health, previous treatment, and the couple’s preferences.

Can Male Infertility Be Prevented?

Not all causes of male infertility can be prevented, particularly genetic or congenital conditions. However, certain steps may help protect reproductive health:

  • Avoid smoking, tobacco, anabolic steroids, and non-prescribed testosterone.

  • Seek timely treatment for relevant reproductive infections.

  • Use protective equipment when required for workplace chemical exposure.

  • Manage chronic health conditions.

  • Discuss fertility preservation before chemotherapy, radiotherapy, or other treatments that may affect sperm production.

  • Seek medical assessment for testicular pain, swelling, lumps, or changes in sexual function.

Early evaluation may help identify treatable conditions and avoid unnecessary delays in fertility care.

When Should a Couple Seek Fertility Evaluation?

A fertility assessment is generally recommended when pregnancy has not occurred after:

  • 12 months of regular, unprotected intercourse if the female partner is under 35.

  • 6 months if the female partner is 35 or older.

Earlier assessment may be appropriate when either partner has known reproductive conditions, previous fertility problems, irregular or absent periods, a history of testicular disease, sexual dysfunction, or other relevant risk factors.

Both partners should ideally be evaluated in parallel so that the couple can receive a coordinated treatment plan.

Frequently Asked Questions

1. Can a man with a low sperm count father a child?

Yes, natural conception may still be possible in some cases. The likelihood depends on the sperm count, motility, other semen parameters, and the fertility of both partners. Treatment or assisted reproduction may improve the available options.

2. Does a normal semen analysis guarantee fertility?

No. A normal result is reassuring but does not guarantee conception. Fertility also depends on factors such as sperm function, timing of intercourse, the female partner’s reproductive health, and other individual circumstances.

3. Can stress cause male infertility?

Stress may affect sexual desire, erectile function, sleep, and lifestyle habits. Its direct effect on sperm quality varies, and persistent fertility problems should be medically evaluated rather than attributed to stress alone.

4. Can diet and supplements improve sperm quality?

A balanced diet and healthy lifestyle support general health, but no supplement is guaranteed to improve fertility. Supplements may not help when a specific medical or structural cause is present. Discuss any product with your healthcare professional before taking it.

5. Is male infertility always permanent?

No. Some causes are treatable or reversible, while others require assisted reproductive techniques. Outcomes depend on the underlying diagnosis and the health of both partners.

6. Can testosterone treatment affect fertility?

Yes. Testosterone taken from outside the body can suppress the hormonal signals needed for sperm production. Men planning to conceive should seek specialist advice before starting or continuing testosterone therapy.

7. What happens if no sperm are found in the semen?

This condition is called azoospermia. Further evaluation can help determine whether sperm production is impaired or sperm transport is blocked. In selected cases, treatment or surgical sperm retrieval may be possible.

8. Should both partners undergo fertility testing?

Yes. Infertility can involve male factors, female factors, both, or an unexplained combination. Evaluating both partners helps avoid delays and supports better-informed treatment decisions.
