Male Infertility in India: Causes, Signs & Which Tests Help Diagnose It

Infertility is often considered a women's health issue, but male health can also play a major role in a couple's ability to conceive. In fact, male factors contribute to a significant proportion of infertility cases worldwide. Yet, many men hesitate to discuss fertility problems because of embarrassment, social pressure, or a lack of awareness.

In India, conversations about infertility can be particularly difficult because of the importance often placed on parenthood and family expectations. Men may avoid seeking medical help, assuming that fertility problems will resolve on their own. However, understanding the causes and getting the right tests can help identify the problem early.

Male infertility does not always cause noticeable physical symptoms. Some men may have a low sperm count or problems with sperm movement without experiencing any changes in their daily lives. This is why medical evaluation is important when a couple has difficulty conceiving.

What Is Male Infertility?

Male infertility refers to a man's reduced ability to contribute to a pregnancy. It can happen when the body does not produce enough healthy sperm, sperm cannot move properly, or sperm cannot reach the female reproductive tract.

For a pregnancy to occur naturally, the testicles need to produce sperm, the sperm must mature and move effectively, and the reproductive system must allow them to travel during ejaculation.

Problems with any of these processes can affect fertility.

Doctors generally consider an infertility evaluation when a couple has been unable to conceive after 12 months of regular, unprotected sexual intercourse. If the female partner is 35 or older, evaluation is usually recommended after six months. Earlier assessment may be appropriate when either partner has known fertility risk factors.

It is also important to remember that infertility does not mean a man can never have children. Many causes can be treated or managed, depending on the underlying problem.

How Common Is Male Infertility in India?

Male infertility is an important reproductive health concern in India, although exact estimates vary between studies and populations.

Several factors can make it difficult to understand the full extent of the problem. Many men do not undergo fertility testing, and social stigma can prevent couples from seeking help.

Another common misconception is that fertility problems are always caused by women. In reality, infertility may be related to the male partner, the female partner, both partners, or unexplained factors.

A fertility evaluation should therefore consider both partners rather than placing the responsibility on one person.

Greater awareness can help men understand that fertility is a health concern, not a measure of masculinity. Getting tested is a practical step towards understanding the problem and choosing the right treatment.

What Are the Common Male Infertility Causes?

Male infertility can develop because of medical conditions, hormonal changes, lifestyle habits, or problems affecting the reproductive system. Identifying the cause helps doctors recommend suitable treatment.

1. Low Sperm Count

A low sperm count means that the semen contains fewer sperm than expected. This can reduce the chances of sperm reaching and fertilising an egg.

Low sperm count may occur because of hormonal problems, testicular conditions, certain infections, or exposure to harmful substances.

However, a low sperm count does not automatically mean that natural conception is impossible. The chances of pregnancy also depend on sperm movement, sperm shape, and other fertility factors.

A sperm count test, usually performed as part of a semen analysis, helps assess the number of sperm present in a semen sample.

2. Poor Sperm Movement

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

When a large proportion of sperm move poorly or cannot move forward effectively, fertilisation may become more difficult.

Poor sperm movement can be associated with infections, oxidative stress, certain medical conditions, and lifestyle factors.

A semen analysis measures sperm motility along with other important characteristics.

3. Abnormal Sperm Shape

Sperm morphology refers to the size and shape of sperm. Sperm with an abnormal shape may have difficulty moving effectively or fertilising an egg.

However, some sperm in a healthy sample will naturally have an abnormal shape. Doctors do not diagnose infertility based on morphology alone. They interpret this result alongside sperm count, motility, medical history, and other findings.

4. Hormonal Imbalances

Hormones play an important role in sperm production. The brain releases signals that help regulate the testicles and support normal reproductive function.

Conditions affecting testosterone or other reproductive hormones can interfere with sperm production.

Possible causes include problems with the pituitary gland, certain genetic conditions, and the use of external testosterone or anabolic steroids.

Men experiencing fertility difficulties may need blood tests to check hormone levels, depending on their symptoms and semen analysis results.

5. Varicocele

A varicocele is an enlargement of the veins inside the scrotum, the pouch of skin that holds the testicles.

It can affect testicular temperature and may be associated with reduced sperm quality in some men. However, not every varicocele causes infertility.

A doctor may identify a varicocele during a physical examination. An ultrasound may be recommended in selected cases.

6. Infections and Reproductive Tract Problems

Certain infections can affect sperm production or damage parts of the reproductive system. In some cases, inflammation or scarring can block the passage through which sperm travel.

Blockages may also occur because of congenital conditions or previous surgery.

Depending on the cause, treatment may involve medication, surgery, or assisted reproductive techniques.

7. Lifestyle and Environmental Factors

Daily habits can influence reproductive health. Some factors associated with poorer sperm quality include:

• Smoking and tobacco use.
• Heavy alcohol consumption.
• Use of recreational drugs or anabolic steroids.
• Obesity and low levels of physical activity.
• Frequent exposure to excessive heat around the testicles.
• Poorly controlled diabetes and certain other chronic conditions.
• Exposure to specific industrial chemicals, pesticides, or other reproductive toxins.

These factors do not affect every man in the same way. Improving lifestyle habits may support reproductive health, but lifestyle changes alone cannot correct every cause of infertility.

8. Age and Medical Treatments

Although male fertility does not stop at a specific age, sperm quality and reproductive outcomes can change as men grow older.

Some medical treatments, including chemotherapy and radiation therapy, can damage sperm production. Certain medicines and previous surgeries may also affect fertility.

Men planning to undergo treatments that could affect fertility should discuss sperm preservation with their doctor beforehand whenever possible.

What Are the Male Infertility Symptoms?

One of the biggest challenges with male infertility is that many men have no obvious symptoms. They may feel healthy and experience no problems during sexual activity, even when sperm production or quality is affected.

Difficulty conceiving is often the first sign that leads a couple to seek medical advice.

However, some male infertility symptoms may point towards an underlying health condition.

Possible Signs to Watch For

• Difficulty achieving a pregnancy: If a couple has been trying to conceive without success, a fertility evaluation may help identify possible causes.
• Changes in sexual function: Erectile difficulties, reduced sexual desire, or problems with ejaculation may sometimes be associated with hormonal or reproductive health conditions.
• Pain or swelling in the testicles: Persistent pain, swelling, a lump, or a feeling of heaviness in the scrotum should be assessed by a healthcare professional.
• Reduced facial or body hair: In some cases, reduced body hair or other changes in sexual development may be associated with hormonal problems.
• A history of testicular problems: Previous undescended testicles, testicular injury, surgery, or certain infections may increase the risk of fertility difficulties.

These signs do not confirm infertility on their own. Likewise, having none of them does not guarantee normal fertility.

If you notice persistent testicular pain or a lump, seek medical assessment. Sudden, severe testicular pain requires emergency care.

Which Tests Help Diagnose Male Infertility?

The right infertility test for men depends on symptoms, medical history, physical examination findings, and how long the couple has been trying to conceive.

Doctors often begin with a semen analysis and recommend additional investigations when needed.

1. Semen Analysis: The Main Initial Test

Semen analysis is generally the first test used to assess male fertility. It examines a semen sample to understand several important characteristics.

These include:

• Sperm concentration: The number of sperm per millilitre of semen.
• Total sperm number: The total number of sperm in the entire sample.
• Sperm motility: How well the sperm move.
• Sperm morphology: The percentage of sperm with a typical shape.
• Semen volume: The amount of semen produced.
• Other characteristics: Depending on the laboratory, the assessment may include pH and signs of inflammation.

The results help doctors understand whether sperm-related factors may be contributing to difficulty conceiving.

A semen analysis is not a complete measure of fertility. Even a result within the laboratory's reference range cannot guarantee pregnancy, and an abnormal result does not automatically mean that pregnancy is impossible.

If the first result is abnormal, the doctor may recommend repeating the test because semen quality can vary over time.

2. Sperm Count Test

A sperm count test measures the number of sperm in a semen sample. It is one of the most commonly discussed investigations when couples are concerned about male fertility.

The test is usually included in a complete semen analysis rather than performed as a separate investigation.

For context, the World Health Organization's sixth-edition semen laboratory manual reports a lower fifth-percentile reference value of approximately 16 million sperm per millilitre and 39 million sperm per ejaculate among men whose partners conceived within 12 months.

These values are reference points, not strict boundaries between fertile and infertile men. A doctor must interpret the complete report alongside the individual's medical history and other test results.

3. Hormone Blood Tests

If semen analysis results are abnormal or the doctor suspects a hormonal problem, blood tests may be recommended.

Depending on the clinical situation, these may include:

• FSH (follicle-stimulating hormone): Helps assess signals involved in sperm production.
• LH (luteinising hormone): Helps regulate testosterone production.
• Total testosterone: Measures the main male sex hormone in the blood.
• Prolactin: May be checked when symptoms or other findings suggest elevated levels.

Not every man needs all these tests. The doctor selects the relevant investigations based on the initial findings.

4. Scrotal Ultrasound

A scrotal ultrasound uses sound waves to examine the testicles and surrounding structures.

It may help identify a varicocele, certain testicular abnormalities, or other structural problems.

This test is not routinely required for every man with infertility. It is generally recommended when the physical examination or medical history suggests that imaging would be useful.

5. Genetic Tests

Genetic testing may be advised in men with very low sperm counts or no sperm in the semen, particularly when a genetic cause is suspected.

Depending on the findings, tests may include a karyotype or Y-chromosome microdeletion analysis. Testing for specific gene changes may also be considered in selected cases.

These investigations can help explain sperm production problems and guide treatment decisions.

6. Other Tests, When Needed

Some men may need additional tests based on their symptoms and initial results. These can include urine testing after ejaculation when retrograde ejaculation is suspected, selected infection tests, or specialised sperm function tests.

Advanced sperm DNA fragmentation testing is not a routine first-line test for every man. It may be considered in specific situations after discussion with a fertility specialist.

The key is to avoid ordering every available test without a clear reason. A doctor can help determine which investigations are appropriate.

How to Prepare for a Sperm Count Test

Following the laboratory's instructions is important for obtaining a useful semen analysis result.

Here are some common preparation steps:

• Follow the recommended abstinence period: Laboratories commonly request two to seven days without ejaculation before sample collection.
• Use the approved collection method: Collect the sample in the sterile container provided or approved by the laboratory.
• Avoid ordinary lubricants: These may affect sperm movement or damage sperm unless the laboratory specifically approves them.
• Collect the complete sample: Tell the laboratory if any portion is missed.
• Follow transport instructions: If the sample is collected at home, confirm whether home collection is permitted and how quickly it must reach the laboratory.
• Share relevant medical information: Inform your doctor about medicines, supplements, recent illnesses, or previous reproductive health problems.

Do not stop prescribed medicines without medical advice.

If a result is abnormal, do not panic. Your doctor may recommend repeating the test under appropriate conditions before deciding what to do next.

Can Male Infertility Be Treated?

Treatment depends on the underlying cause, the severity of the problem, and the fertility needs of both partners.

Some men may benefit from treating a hormonal disorder, managing an infection, or undergoing surgery for a suitable varicocele or reproductive tract blockage.

Lifestyle changes, such as stopping smoking, limiting alcohol, maintaining a healthy weight, exercising regularly, and managing chronic health conditions, may also support reproductive health.

In selected cases, fertility specialists may recommend assisted reproductive techniques such as intrauterine insemination, in vitro fertilisation (IVF), or intracytoplasmic sperm injection (ICSI).

When sperm production is severely affected, sperm retrieval procedures may be considered.

Treatment is not the same for everyone, and improvement may take several months because sperm production takes time. Testosterone treatment should not be started casually by men trying to conceive because external testosterone can suppress sperm production.

If you and your partner have been trying to conceive without success, consider seeking medical advice rather than relying on supplements or home remedies. An appropriate infertility test for men can help guide the next steps.

When Should You See a Doctor?

Consider consulting a healthcare professional if:

• You have been trying to conceive for 12 months without success, or six months if your female partner is 35 or older.
• You have a history of testicular injury, undescended testicles, or reproductive surgery.
• You have persistent erectile or ejaculation difficulties.
• You notice testicular pain, swelling, or a lump.
• You have previously received chemotherapy or radiation therapy.
• You have been told that your sperm count is low or your semen analysis is abnormal.

Do not wait for visible male infertility symptoms before seeking advice if you have known risk factors.

Early evaluation can help identify treatable conditions, clarify the available options, and reduce unnecessary uncertainty.

Conclusion

Male infertility is a medical concern that deserves attention, understanding, and timely care. It can result from low sperm count, poor sperm movement, hormonal imbalances, reproductive tract problems, lifestyle factors, or other underlying conditions.

The good news is that an evaluation can often help identify the possible cause and guide the next steps. A semen analysis, which usually includes a sperm count test, is an important starting point for many men.

Most importantly, fertility problems should not be treated as a source of shame. Both partners deserve appropriate medical evaluation and support.

If you are concerned about your reproductive health, speak with a qualified healthcare professional and explore suitable testing options. With the right information and guidance, you can make informed decisions about your fertility and future family plans.
