Male infertility refers to male reproductive factors that may reduce the likelihood of achieving pregnancy. These factors may involve sperm production, sperm movement, sperm function, reproductive hormones or blockages affecting sperm transport.
Fertility difficulties can involve male factors, female factors or a combination of both. Therefore, evaluating both partners is an important part of fertility assessment.
Dr. Prakash Sankapal, a urologist in Navi Mumbai , provides urology consultations at NewEra Hospitals, Vashi, and JP Kidney Care, Ulwe. Male infertility evaluation may involve medical history, clinical examination and appropriate investigations.
What Is Male Infertility?
Male infertility is a condition in which male reproductive factors may contribute to difficulty achieving pregnancy. It may be associated with abnormal sperm production, impaired sperm function, hormonal conditions or obstruction within the reproductive tract.
Infertility is commonly evaluated when pregnancy has not occurred after 12 months of regular unprotected sexual intercourse.
Earlier assessment may be appropriate when the female partner is aged 35 or older, or when either partner has known fertility-related risk factors.
Important: An abnormal semen analysis does not automatically establish permanent infertility. Results must be interpreted alongside medical history, examination and other relevant findings.
What Causes Infertility in Men?
Male infertility may result from several medical, genetic, hormonal or lifestyle factors. In some individuals, no clear cause is identified.
1. Problems with Sperm Production
Some men produce fewer sperm than expected or have abnormalities affecting sperm movement or shape. These changes may influence reproductive potential.
2. Varicocele
A varicocele is an enlargement of veins around the testicle. It may be associated with impaired sperm production or semen abnormalities in selected individuals.
Not every varicocele causes infertility or requires treatment.
3. Hormonal Conditions
Abnormalities involving the hypothalamus, pituitary gland or testes may interfere with sperm production.
Hormonal assessment may be indicated when clinical findings suggest endocrine dysfunction.
4. Reproductive Tract Obstruction
A blockage involving the epididymis, vas deferens or ejaculatory ducts may prevent sperm from reaching the semen.
Obstruction may be congenital or associated with infection, injury or previous procedures.
5. Genetic Conditions
Certain chromosomal or genetic conditions, including Klinefelter syndrome and selected Y-chromosome abnormalities, can affect sperm production.
Genetic testing may be considered for specific semen abnormalities and clinical findings.
6. Infection or Inflammation
Some infections or inflammatory conditions involving reproductive structures may affect fertility.
Assessment and treatment depend on the identified cause rather than infertility symptoms alone.
7. Lifestyle and Medical Factors
Smoking, excessive alcohol consumption, obesity, anabolic steroid use, certain medicines and environmental exposures may affect reproductive health.
The strength of evidence varies between individual risk factors.
What Are the Symptoms of Male Infertility?
The main indication of possible infertility is difficulty achieving pregnancy with a partner. Many men have no obvious physical symptoms.
Some individuals may experience associated symptoms:
- Difficulty conceiving after regular unprotected intercourse.
- Problems with ejaculation or unusually low semen volume.
- Reduced sexual desire.
- Erectile difficulties.
- Pain, swelling or a lump in the testicular area.
- Changes in testicular size.
- Reduced facial or body hair associated with certain hormonal conditions.
- Abnormal semen analysis results.
These findings do not independently confirm infertility and may have different medical causes.
When Should a Man Seek Fertility Evaluation?
Fertility evaluation may be appropriate when pregnancy has not occurred within the expected timeframe or when known reproductive concerns are present.
- No pregnancy after 12 months of regular unprotected intercourse.
- No pregnancy after 6 months when the female partner is aged 35 or older.
- A previous abnormal semen analysis.
- Known history of undescended testes, testicular injury or reproductive surgery.
- Previous cancer treatment that may affect fertility.
- Suspected hormonal or genetic abnormalities.
- Persistent sexual or ejaculation difficulties.
Medical note: A new testicular lump, sudden severe testicular pain or significant swelling should be evaluated promptly. Sudden severe pain requires emergency assessment.
How Is Male Infertility Diagnosed?
Evaluation begins with reproductive history, medical history and clinical examination. Investigations are selected according to individual findings.
1. Medical and Reproductive History
The clinician reviews the duration of fertility difficulties, previous pregnancies, sexual and ejaculation history, childhood conditions, previous operations, medicines and lifestyle factors.
2. Physical Examination
Examination may include assessment of the testes, scrotum, vas deferens and possible varicocele, according to clinical need.
3. Semen Analysis
Semen analysis evaluates parameters including sperm concentration, total sperm number, motility and morphology.
Because semen parameters can vary, repeat testing may be recommended, particularly when an initial result is abnormal.
4. Hormonal Assessment
Blood tests for follicle-stimulating hormone (FSH), testosterone and other hormones may be considered when clinically indicated.
5. Scrotal Ultrasound
Ultrasound may help evaluate selected testicular or scrotal abnormalities. It is not routinely required for every patient.
6. Genetic Testing
Karyotyping, Y-chromosome microdeletion analysis or other genetic tests may be recommended for selected patients, depending on semen findings and clinical assessment.
7. Additional Investigations
Selected patients may require further reproductive tract imaging, infection assessment or other specialised tests. These are not necessary for everyone.
The AUA/ASRM guidelines for male infertility evaluation recommend assessment of both partners and an initial male reproductive history with semen analysis.
What Does a Semen Analysis Report Show?
A semen analysis is an important investigation in male fertility evaluation. It provides information about several sperm and semen characteristics.
| Parameter | What It Indicates |
|---|---|
| Semen Volume | Amount of semen produced during ejaculation. |
| Sperm Concentration | Number of sperm per millilitre of semen. |
| Total Sperm Number | Estimated total number of sperm in the ejaculate. |
| Motility | Proportion of sperm demonstrating movement. |
| Morphology | Proportion of sperm with assessed normal shape. |
| Vitality | Proportion of living sperm, assessed when indicated. |
Important: Semen reference values are not absolute boundaries between fertility and infertility. A clinician must interpret results alongside the couple’s reproductive history and other findings.
What Are the Treatment Options for Male Infertility?
Treatment depends on the identified cause, test results, reproductive goals and the fertility assessment of both partners.
Not every condition can be reversed, and no single treatment is suitable for everyone.
1. Lifestyle and Health Measures
Appropriate measures may include smoking cessation, weight management, reducing excessive alcohol consumption and reviewing medications that could affect fertility.
Benefits vary, and lifestyle changes do not correct every underlying fertility problem.
2. Management of Hormonal Disorders
Selected hormonal conditions may be treated using medicines prescribed according to the diagnosed endocrine abnormality.
Testosterone replacement should not be used as a fertility treatment in men trying to conceive, because external testosterone may suppress sperm production.
3. Varicocele Repair
Varicocele repair may be considered in selected men with a palpable varicocele, infertility and abnormal semen parameters.
Surgery is not indicated for all varicoceles and does not guarantee pregnancy.
4. Treatment of Reproductive Tract Obstruction
Selected blockages may be managed through reconstructive procedures or sperm retrieval, depending on the location and cause of obstruction.
The suitability of surgery depends on individual findings.
5. Sperm Retrieval Procedures
Surgical sperm retrieval may be considered for selected patients when sperm are absent from ejaculated semen.
Techniques may include testicular sperm extraction or other methods, depending on the diagnosis. Sperm retrieval is not successful in every individual.
6. Assisted Reproductive Technologies
Assisted reproductive technologies may include intrauterine insemination (IUI), in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) in suitable circumstances.
These approaches require fertility specialist assessment and depend on both partners’ reproductive factors.
Important: Fertility treatment does not guarantee pregnancy or a live birth. Expected benefits, limitations, possible risks and alternatives should be discussed based on individual findings.
Comparing Male Infertility Management Options
Management approaches address different causes of infertility.
| Management | General Consideration |
|---|---|
| Lifestyle Measures | Address potentially modifiable risk factors. |
| Hormonal Treatment | For selected diagnosed hormonal conditions. |
| Varicocele Repair | Selected patients with clinically relevant varicocele. |
| Reconstructive Surgery | Certain reproductive tract obstructions. |
| Sperm Retrieval | Selected patients with azoospermia. |
| IUI / IVF / ICSI | Assisted reproduction according to the couple’s clinical circumstances. |
Decisions may involve collaboration between a urologist, reproductive medicine specialist and other relevant healthcare professionals.
What Is Azoospermia?
Azoospermia refers to the absence of sperm in the ejaculated semen after appropriate laboratory examination.
It may be associated with obstruction of the reproductive tract or impaired sperm production.
Further evaluation may include physical examination, hormone tests, repeat semen analysis and selected genetic investigations.
Treatment options depend on the underlying diagnosis. Some men may be considered for reconstructive treatment or sperm retrieval, while other cases may have limited available interventions.
Can Varicocele Cause Male Infertility?
Varicocele is an enlargement of veins within the scrotum. In some men, it is associated with impaired semen quality or fertility difficulties.
A varicocele does not always lead to infertility, and many affected men do not require treatment.
Clinical significance is assessed according to examination findings, semen analysis, reproductive history and the couple’s circumstances.
What Are the Risks and Limitations of Treatment?
The potential risks depend on the treatment being considered.
- Surgical complications such as bleeding, infection or pain.
- Recurrence or persistence of certain conditions after treatment.
- Failure to retrieve sperm during a sperm retrieval procedure.
- Hormonal medication side effects.
- Fertility outcomes that remain uncertain despite treatment.
- Psychological, emotional or financial burdens associated with prolonged fertility care.
Appropriate counselling should address likely benefits, treatment limitations, alternatives and follow-up requirements.

Frequently Asked Questions About Male Infertility
Male infertility involves reproductive factors that may reduce the likelihood of achieving pregnancy. These may affect sperm production, sperm function or sperm transport.
Causes may include sperm production problems, varicocele, hormonal abnormalities, reproductive tract obstruction, genetic conditions or certain lifestyle and medical factors.
Yes. Many men have no noticeable symptoms, and difficulty achieving pregnancy may be the first indication of a fertility problem.
Evaluation may include semen analysis, reproductive history, physical examination and selected hormone or genetic tests. Additional investigations depend on clinical findings.
Low sperm count may reduce the likelihood of conception. However, sperm count alone cannot reliably predict fertility. Other semen parameters and both partners’ clinical factors matter.
Yes. Varicocele may be associated with impaired semen quality in selected men. Not every varicocele causes infertility or requires treatment.
Azoospermia means no sperm are found in the ejaculated semen after appropriate laboratory examination. It may result from obstruction or impaired sperm production.
No. Some causes may be treated or managed, while others cannot be reversed. Assisted reproductive options may be considered in selected circumstances. Pregnancy is not guaranteed.
Yes. Fertility difficulties may involve male factors, female factors or both. Concurrent evaluation is recommended to guide decisions appropriately.
