Male infertility can result from impaired sperm production, poor sperm quality, or a problem that prevents sperm from reaching and fertilizing the egg.
Treatment for male infertility varies according to the underlying cause. Mild cases may improve through medical guidance, lifestyle changes, or medication, while severe male infertility may require advanced surgical procedures or assisted reproductive technologies.
Modern medical techniques have helped many couples achieve their dream of parenthood, even in complex cases such as azoospermia, commonly known as a zero sperm count.
In this article, we explain the causes, symptoms, diagnosis, and treatment of male infertility, as well as the advanced technologies available at Dr. Mohamed Wael Ragab Clinics.
What Causes Male Infertility?
Most cases of male infertility are associated with a medical condition that affects the number, quality, movement, or function of sperm in the semen. This may reduce the likelihood of fertilizing an egg and achieving pregnancy.
Common sperm-related causes of male infertility include:
- Low sperm count or complete absence of sperm.
- Poor sperm motility.
- Increased sperm abnormalities.
- A high percentage of dead sperm.
- Increased sperm DNA fragmentation.
The testicles may produce fewer sperm or sperm of lower quality due to impaired testicular function. In other cases, the testicles may function normally, but an obstruction within the male reproductive tract prevents sperm from appearing in the ejaculated semen.
Ejaculatory disorders, including anejaculation and retrograde ejaculation, may also contribute to male infertility.
The most important medical conditions and risk factors associated with male infertility include the following.
Varicocele
A varicocele is one of the most common causes of male infertility. It consists of enlarged and irregular veins within the scrotum caused by abnormal blood accumulation and impaired venous drainage from the testicle.
Varicoceles may negatively affect sperm count and quality through several mechanisms, including increased scrotal temperature and oxidative stress.
Undescended Testicle
An undescended testicle occurs when one or both testicles fail to move into the scrotum.
Because the scrotum provides the lower temperature required for normal testicular development and sperm production, an undescended testicle may impair testicular function and reduce fertility.
Hormonal Disorders
Male infertility may result from hormonal abnormalities, including:
- Low testosterone levels.
- Reduced secretion of follicle-stimulating hormone, or FSH.
- Reduced secretion of luteinizing hormone, or LH.
- Elevated prolactin levels.
- Pituitary gland disorders.
- Hyperthyroidism.
These hormonal imbalances may interfere with normal testicular function and sperm production.
Azoospermia
Azoospermia is the complete absence of sperm from the ejaculate. It may be caused by an obstruction in the reproductive tract or by impaired sperm production within the testicles.
When no sperm are present in the semen, natural conception is not possible. However, advanced sperm retrieval techniques may allow sperm to be collected directly from the testicle or epididymis for use in intracytoplasmic sperm injection, or ICSI.
Immune Disorders
In some men, the immune system may produce antisperm antibodies that mistakenly attack sperm cells.
These antibodies may interfere with sperm movement, function, and the ability to fertilize an egg.
Genetic Abnormalities
Certain genetic and chromosomal conditions may affect male fertility, including:
- Klinefelter syndrome.
- Kallmann syndrome.
- Y-chromosome microdeletions.
- Abnormalities affecting the azoospermia factor, or AZF, regions.
Genetic testing may be particularly important in men with severe oligospermia or non-obstructive azoospermia.
Chronic Infections
Chronic prostatitis may negatively affect semen quality and sperm function.
Chronic infections affecting the testicle or epididymis may also impair sperm production and quality. In some cases, inflammation can cause scar tissue that blocks the reproductive tract and prevents sperm from entering the semen.
Retrograde Ejaculation
Retrograde ejaculation occurs when semen flows backward into the bladder instead of leaving the body through the urethra during ejaculation.
This may result in a very low semen volume or a complete absence of visible ejaculate, making natural conception difficult.
Possible causes include:
- Diabetes.
- Pelvic surgery.
- Nerve damage.
- Certain medications.
- Some surgical treatments for benign prostatic hyperplasia.
Medications and Hormonal Products
Certain medications and substances may reduce male fertility or increase the risk of infertility, including:
- Testosterone replacement therapy.
- Anabolic steroids.
- Anti-androgen medications.
- Chemotherapy.
- Some hormonal treatments.
Taking external testosterone can suppress the hormonal signals required for the testicles to produce sperm. Men who are planning to conceive should not start or stop hormonal therapy without consulting a qualified physician.
Environmental and Lifestyle Factors
Male fertility may also be affected by several environmental and lifestyle factors, including:
- Increasing age.
- Obesity.
- Smoking.
- Physical inactivity.
- Repeated exposure to high temperatures.
- Exposure to radiation.
- Exposure to toxic chemicals.
- Wearing excessively tight clothing.
- Poor nutrition.
- Chronic stress.
Approximately 10% to 20% of male infertility cases may be classified as unexplained or idiopathic infertility. In these cases, the man may experience difficulty achieving pregnancy despite apparently normal routine test results.
Symptoms of Male Infertility
Male infertility does not always cause obvious symptoms. Many men only discover a fertility problem after undergoing a semen analysis or other investigations following delayed conception.
However, some medical conditions associated with infertility may cause symptoms such as:
- Erectile dysfunction.
- Testicular pain or swelling.
- Reduced sexual desire.
- Low semen volume.
- Difficulty ejaculating.
- Complete absence of ejaculation.
Possible Signs of Male Infertility Before Marriage
In addition to the symptoms mentioned above, certain physical signs may indicate the need for a fertility or hormonal assessment before marriage.
These signs may include:
- Gynecomastia.
- An undescended testicle.
- An unusually small penis.
- Small, atrophic, or shrunken testicles.
- Reduced facial or body hair.
- Delayed or absent secondary male sexual characteristics.
- Lack of voice deepening.
- Reduced muscle development.
These findings do not automatically confirm infertility. However, anyone who notices such signs should consider undergoing a medical evaluation and appropriate premarital testing to assess hormonal and reproductive health.
How Is Male Infertility Diagnosed?
A fertility evaluation is generally recommended when pregnancy has not occurred after 12 months of regular, unprotected intercourse.
Both partners should usually be evaluated because infertility may involve male factors, female factors, or a combination of both.
The investigations required to diagnose male infertility depend on the physician’s assessment of the individual case.
Medical History and Physical Examination
The physician reviews the patient’s medical and reproductive history and performs a physical examination.
The evaluation may include:
- Examining the testicles and scrotum.
- Looking for signs of varicocele.
- Assessing possible signs of low testosterone.
- Reviewing chronic medical conditions.
- Discussing previous surgeries or injuries.
- Reviewing current medications and supplements.
- Asking about lifestyle and occupational exposures.
- Evaluating sexual and ejaculatory function.
Semen Analysis
Semen analysis is one of the most important tests used to evaluate male fertility.
It provides information about:
- Sperm concentration.
- Total sperm count.
- Sperm motility.
- Sperm morphology.
- Semen volume.
- Semen liquefaction and viscosity.
- Other characteristics of the seminal fluid.
Because semen parameters can vary, the physician may request more than one semen sample before reaching a final conclusion.
Scrotal Ultrasound
A scrotal ultrasound can help identify varicoceles, testicular abnormalities, masses, or other structural problems.
It may also help determine the size and severity of a varicocele, allowing the physician to select the most appropriate treatment.
Hormonal Testing
Blood tests may be used to measure hormones involved in sperm production and male reproductive function, including:
- Testosterone.
- Follicle-stimulating hormone, or FSH.
- Luteinizing hormone, or LH.
- Prolactin.
- Thyroid hormones.
Hormonal results may help determine whether infertility is related to the testicles, pituitary gland, hypothalamus, or another endocrine disorder.
Antisperm Antibody Testing
Antisperm antibody testing may be requested in selected cases to determine whether the immune system is producing antibodies that interfere with sperm movement or function.
Sperm DNA Fragmentation Testing
A sperm DNA fragmentation test measures the percentage of damaged or fragmented genetic material within sperm cells.
Higher levels of sperm DNA fragmentation may be associated with:
- Reduced fertility.
- Poor embryo development.
- Lower assisted reproduction success rates.
- An increased risk of early miscarriage.
The clinical significance of the result should always be interpreted alongside the semen analysis, medical history, and other fertility investigations.
Genetic Testing
Genetic testing may be recommended in men with azoospermia, severe oligospermia, or suspected hereditary conditions.
Testing may include:
- Karyotype analysis.
- Y-chromosome microdeletion testing.
- AZF region analysis.
- Other genetic tests selected according to the individual case.
Genetic counseling may also be recommended before treatment or assisted reproduction.
Can Male Infertility Be Treated?
Yes. Many cases of male infertility can be treated by correcting the underlying cause, improving sperm quality, surgically retrieving sperm, or using assisted reproductive technologies.
According to the StatPearls classification cited in the source material:
- Approximately 18% of male infertility cases may be directly treatable, such as certain cases involving varicocele.
- Approximately 70% may require assisted reproductive technologies, including cases involving significant sperm abnormalities.
- Approximately 12% may not currently be treatable, including some cases of Sertoli cell-only syndrome.
The treatment plan and probability of success vary according to the cause of infertility, testicular function, genetic findings, the female partner’s fertility, and previous treatment history.
Male Infertility Treatment Options
Treatment is selected according to the underlying cause and may include lifestyle changes, medications, hormonal therapy, surgery, sperm retrieval, or assisted reproduction.
Lifestyle Improvement
A healthier lifestyle may improve male reproductive health and support sperm production.
Recommended changes may include:
- Reducing psychological stress.
- Stopping smoking.
- Achieving a healthy body weight.
- Getting adequate sleep.
- Stopping anabolic steroid use under medical supervision.
- Increasing physical activity.
- Exercising regularly without overtraining.
- Following a balanced diet rich in natural antioxidants.
- Avoiding repeated exposure to excessive heat.
- Avoiding unnecessarily tight clothing.
Lifestyle improvement may support fertility, but it does not replace medical treatment when a structural, hormonal, genetic, or severe testicular problem is present.
Antioxidant Supplements
Antioxidants may help reduce oxidative stress, support testicular function, and improve certain sperm parameters in selected patients.
Common antioxidant supplements used in male fertility care include:
- Zinc.
- L-carnitine.
- Coenzyme Q10.
- Vitamin E.
- Vitamin C.
- Folic acid.
- Selenium.
- N-acetylcysteine.
Antioxidant treatment may be helpful alongside lifestyle changes in mild cases. However, supplements should only be taken in the doses recommended by a physician.
Excessive or inappropriate antioxidant use may produce unwanted effects and does not guarantee improved fertility.
Hormonal Therapy
Some cases of male infertility require hormonal treatment to stimulate testicular function and support sperm production.
Depending on the diagnosis, treatment may include:
- Clomiphene citrate.
- Tamoxifen.
- Aromatase inhibitors.
- Human chorionic gonadotropin, or hCG.
- Other gonadotropin treatments when medically indicated.
Hormonal therapy should only be prescribed after appropriate testing because the correct treatment depends on the specific hormonal abnormality.
Varicocele Treatment
Not every varicocele causes infertility or requires treatment.
However, a clinically significant varicocele may affect semen analysis results, testicular function, or sperm quality, particularly when associated with abnormal semen parameters or testicular discomfort.
Treatment options may include:
- Laparoscopic varicocele repair.
- Interventional radiology embolization.
- Microsurgical varicocelectomy.
Dr. Mohamed Wael Ragab has extensive experience in microsurgical varicocele repair.
Microsurgical varicocelectomy is widely used because its enhanced surgical precision helps identify and preserve important structures surrounding the affected veins. It may also be associated with a lower recurrence rate than some other approaches when performed by an experienced microsurgeon.
Treatment of Obstructive Azoospermia
In obstructive azoospermia, the testicles may continue producing sperm, but an obstruction prevents sperm from reaching the ejaculate.
Treatment may involve surgically repairing the obstruction and restoring continuity within the reproductive tract.
When reconstruction is not possible or is unlikely to be successful, sperm may be retrieved directly from the testicle or epididymis and used for assisted reproduction.
Microdissection Testicular Sperm Extraction: Micro-TESE
Microdissection testicular sperm extraction, commonly known as Micro-TESE, is an advanced surgical technique used to search for and retrieve sperm directly from testicular tissue.
It is particularly important in the treatment of non-obstructive azoospermia, where sperm production may occur only in very small and scattered areas within the testicle.
During Micro-TESE, the surgeon uses a high-powered operating microscope to identify enlarged or more promising seminiferous tubules that may contain sperm-producing activity.
The retrieved tissue is carefully examined in the laboratory to search for viable sperm.
When sperm are successfully retrieved, they may be used for intracytoplasmic sperm injection to fertilize the female partner’s eggs and create embryos.
The success rate of Micro-TESE varies according to several factors, including:
- The underlying cause of azoospermia.
- Testicular histology.
- Hormonal results.
- Genetic findings.
- Previous testicular procedures.
- The experience of the surgical and laboratory teams.
Dr. Mohamed Wael Ragab performs Micro-TESE using an advanced German approach designed to allow a comprehensive and precise examination of testicular tissue.
The clinics also use modern artificial intelligence technologies, including Sperm Search AI, to support the laboratory search for rare sperm cells and improve the efficiency of sperm identification in complex cases.
Intracytoplasmic Sperm Injection: ICSI
Intracytoplasmic sperm injection is an assisted fertilization technique in which a single sperm cell is injected directly into an egg.
The procedure generally involves:
- Stimulating the ovaries to produce multiple eggs.
- Retrieving mature eggs.
- Selecting suitable sperm.
- Injecting one sperm into each mature egg.
- Monitoring embryo development in the laboratory.
- Selecting the most suitable embryo or embryos.
- Transferring the selected embryo into the uterus.
Sperm quality is one of several factors that may affect fertilization, embryo development, and the overall success of ICSI.
Dr. Mohamed Wael Ragab Clinics use advanced sperm preparation and selection technologies, including MACS and ZyMōt.
These techniques may help select sperm with more favorable characteristics and reduce the use of sperm showing certain abnormalities that could negatively affect fertilization or embryo quality.
The appropriate sperm selection method is determined according to the semen analysis, sperm DNA fragmentation results, previous ICSI outcomes, and the physician’s assessment.

Frequently Asked Questions About Male Infertility
What Are the Most Difficult Types of Male Infertility to Treat?
Non-obstructive azoospermia is considered one of the most challenging forms of male infertility.
In these cases, sperm production may be extremely limited and may occur only in small, isolated areas of the testicle.
However, Micro-TESE, advanced embryology laboratory techniques, and artificial intelligence-assisted sperm search technologies have created new possibilities for sperm retrieval in selected men with non-obstructive azoospermia.
The chances of finding sperm depend on the underlying cause, genetic findings, hormonal status, testicular condition, and previous treatment history.
Does Male Infertility Mean a Man Has Erectile Dysfunction?
No. Male infertility does not necessarily mean that a man has erectile dysfunction.
A man may have normal sexual desire, erections, ejaculation, and sexual performance while still having a problem with sperm count, quality, movement, or production.
However, certain medical conditions may cause both infertility and sexual dysfunction. Examples include severe hormonal disorders and some genetic conditions, such as Klinefelter syndrome.
Can Pregnancy Occur When the Male Partner Is Infertile?
Yes. Pregnancy may still be possible in many cases of male infertility.
Treatment may involve:
- Correcting the underlying medical cause.
- Hormonal treatment.
- Varicocele repair.
- Surgical reconstruction of an obstruction.
- Surgical sperm retrieval.
- Intrauterine insemination in selected cases.
- In vitro fertilization.
- Intracytoplasmic sperm injection.
The most appropriate option depends on the diagnosis and the fertility evaluation of both partners.
Some severe forms of male infertility may remain difficult or impossible to treat with currently available techniques. A complete evaluation is therefore necessary to determine realistic treatment options and expected outcomes.
