VARICOCELE AND MALE FERTILITY: WHAT EVERY MAN SHOULD KNOW

INTRODUCTION

A varicocele is one of the most common and most treatable causes of male infertility. It affects approximately 15% of all men and is found in up to 40% of men being evaluated for primary infertility. Among men with secondary infertility (those who have previously fathered a child but later experience infertility), the prevalence may be even higher.

Despite its frequency, many men have never heard of a varicocele until they begin investigating fertility problems. Others discover it accidentally during a routine physical examination or after noticing enlarged veins in the scrotum.

Not every man with a varicocele becomes infertile, and not every varicocele requires treatment. However, in selected men, a varicocele can reduce sperm production, impair sperm function, damage sperm DNA, and lower testosterone production, ultimately reducing the chances of natural conception.

Fortunately, advances in microsurgical techniques and interventional radiology have made treatment safer and more effective than ever before. For appropriately selected patients, repairing a varicocele may improve semen quality, increase the likelihood of natural pregnancy, and enhance the success of assisted reproductive treatments.

This comprehensive guide explains what a varicocele is, why it affects fertility, how it is diagnosed, available treatment options, and what couples can realistically expect after treatment.

WHAT IS A VARICOCELE?

A varicocele is an abnormal enlargement and twisting of the veins within the pampiniform venous plexus, a network of veins responsible for draining blood from the testes.

It is similar to varicose veins that develop in the legs.

Normally, tiny valves inside these veins prevent blood from flowing backward. When these valves become weak or fail to function properly, blood pools within the veins, causing them to enlarge.

Over time, this abnormal pooling of blood may interfere with the normal environment required for healthy sperm production.

WHY DOES A VARICOCELE USUALLY OCCUR ON THE LEFT SIDE?

Approximately 80–90% of varicoceles occur on the left side.

This is largely due to differences in venous anatomy.

The left testicular vein drains into the left renal vein at a right angle before reaching the inferior vena cava, creating relatively higher venous pressure.

By contrast, the right testicular vein drains more directly into the inferior vena cava, making abnormal blood pooling less common.

Some men develop:

• Left-sided varicoceles.
• Bilateral (both-sided) varicoceles.
• Rarely, isolated right-sided varicoceles.

A new-onset isolated right-sided varicocele, particularly in older men, may warrant additional evaluation to exclude uncommon underlying causes of venous obstruction.

HOW COMMON IS A VARICOCELE?

Varicoceles are common.

Research suggests they occur in:

• Approximately 15% of the general male population.
• Around 35–40% of men with primary infertility.
• Up to 70–80% of men with secondary infertility in some studies.

However, many men with varicoceles remain fertile throughout life.

The presence of a varicocele alone does not automatically mean infertility.

HOW DOES A VARICOCELE AFFECT FERTILITY?

Healthy sperm production requires the testes to remain 2–4°C cooler than normal body temperature.

The pampiniform venous plexus acts as a natural cooling system by allowing heat exchange between incoming arterial blood and outgoing venous blood.

A varicocele disrupts this cooling mechanism.

Several mechanisms may contribute to reduced fertility.

INCREASED TESTICULAR TEMPERATURE

This is the most widely accepted explanation.

Blood pooling around the testes increases local temperature.

Even a small rise in temperature may impair:

• Sperm production.
• Sperm maturation.
• Sperm motility.
• Testicular enzyme activity.

Over time, prolonged heat exposure may reduce overall semen quality.

OXIDATIVE STRESS

A varicocele increases the production of reactive oxygen species (ROS).

In small amounts, ROS are important for normal sperm function.

However, excessive ROS may:

• Damage sperm cell membranes.
• Reduce sperm motility.
• Fragment sperm DNA.
• Increase abnormal sperm morphology.
• Reduce fertilization potential.

Oxidative stress is considered one of the major pathways through which varicoceles impair fertility.

REDUCED OXYGEN SUPPLY

Poor venous drainage may reduce efficient blood circulation within the testes.

Reduced oxygen delivery can impair the function of the sperm-producing cells and negatively affect spermatogenesis.

ACCUMULATION OF HARMFUL METABOLITES

Abnormal venous drainage may allow waste products and potentially harmful substances to accumulate within the testicular environment.

These substances may interfere with normal cellular function and contribute to progressive testicular damage.

HORMONAL CHANGES

The testes produce both sperm and testosterone.

Some men with large or long-standing varicoceles experience impaired function of Leydig cells, the cells responsible for testosterone production.

Reduced testosterone may contribute to:

• Decreased libido.
• Reduced energy.
• Erectile dysfunction.
• Impaired sperm production.

Not every man with a varicocele develops low testosterone, but the risk appears to increase with larger or longstanding varicoceles.

DAMAGE TO SPERM DNA

Modern fertility research has shown that men with clinically significant varicoceles are more likely to have increased sperm DNA fragmentation.

DNA damage may contribute to:

• Reduced fertilization rates.
• Poor embryo development.
• Recurrent miscarriage.
• Lower pregnancy rates.
• Reduced live birth rates in some couples.

Successful treatment may reduce DNA fragmentation in selected men.

WHO IS MOST AT RISK?

Certain men are more likely to develop a varicocele or experience fertility problems related to it.

Risk factors include:

• Family history of varicocele.
• Adolescence and young adulthood.
• Tall body stature (reported in some studies).
• Occupations involving prolonged standing.
• Heavy physical exertion.
• Existing infertility.

Having one or more of these risk factors does not necessarily mean that a man will become infertile, but it may justify closer evaluation if fertility problems arise.

CAN A VARICOCELE GET WORSE OVER TIME?

In some men, yes.

Although many varicoceles remain stable for years, others may gradually enlarge and lead to:

• Progressive decline in sperm quality.
• Testicular shrinkage (testicular atrophy).
• Chronic scrotal discomfort.
• Declining testosterone production.

Regular follow-up may be recommended for men with known varicoceles, particularly adolescents with evidence of reduced testicular growth or adults planning future fertility.

EARLY RECOGNITION IS IMPORTANT

Because many men have no symptoms, a varicocele may go unnoticed until fertility testing is performed.

Early recognition allows timely evaluation and helps determine whether observation, lifestyle modification, or treatment is the most appropriate course of action.

SYMPTOMS OF A VARICOCELE

One of the unique features of a varicocele is that many men experience no symptoms at all. In fact, a significant number of varicoceles are discovered incidentally during routine medical examinations, infertility evaluations, military or sports medical screenings, or investigations for unrelated conditions.

When symptoms do occur, they often develop gradually and may worsen over time.

Common symptoms include:

• A dull aching pain in the scrotum.
• A feeling of heaviness or dragging in the scrotum.
• Enlarged or visibly swollen veins.
• A "bag of worms" sensation above the testicle.
• One testicle appearing smaller than the other.
• Infertility.
• Occasionally, reduced testosterone-related symptoms such as decreased libido or fatigue.

Symptoms frequently worsen after prolonged standing, strenuous physical activity, or at the end of the day, and they often improve when lying down.

SCROTAL PAIN

Pain associated with a varicocele is usually different from the sudden severe pain seen with conditions such as testicular torsion.

Typical characteristics include:

• Dull ache.
• Mild to moderate discomfort.
• Feeling of pressure.
• Heaviness.
• Discomfort after prolonged standing.
• Relief when lying down.

Severe, sudden scrotal pain is not typical of a varicocele and requires urgent medical evaluation to exclude emergencies such as testicular torsion.

TESTICULAR ATROPHY

A longstanding or large varicocele may contribute to testicular atrophy, meaning shrinkage of the affected testicle.

This occurs because prolonged impairment of blood flow, increased temperature, and oxidative stress may gradually damage the sperm-producing tissue.

In adolescents, differences in testicular size may influence decisions regarding treatment because continued growth of the testes is important for future fertility.

INFERTILITY MAY BE THE ONLY SIGN

Many men with varicoceles have:

• No pain.
• Normal erections.
• Normal ejaculation.
• Normal sexual desire.

Their only indication of a problem is difficulty achieving pregnancy with their partner.

This is why fertility evaluation should include examination of the male partner even when he feels completely healthy.

HOW DO DOCTORS GRADE A VARICOCELE?

Varicoceles are commonly classified into three clinical grades based on physical examination.

GRADE I VARICOCELE

A Grade I varicocele is:

• Small.
• Not visible.
• Not felt at rest.

It becomes detectable only when the patient performs a Valsalva maneuver—bearing down as though trying to exhale with the mouth and nose closed—which temporarily increases pressure within the abdominal veins.

GRADE II VARICOCELE

A Grade II varicocele is:

• Not usually visible.
• Easily felt during physical examination without requiring a Valsalva maneuver.

GRADE III VARICOCELE

A Grade III varicocele is:

• Large.
• Easily visible.
• Easily felt.

The enlarged veins often resemble a "bag of worms," which is considered the classic clinical description.

SUBCLINICAL VARICOCELE

Some men have a subclinical varicocele, meaning it cannot be detected during physical examination but is identified on ultrasound.

Current evidence generally does not support surgical repair of isolated subclinical varicoceles in infertile men because clear improvements in fertility outcomes have not been consistently demonstrated.

HOW IS A VARICOCELE DIAGNOSED?

Diagnosis begins with a thorough medical history and physical examination.

Additional investigations may be recommended depending on symptoms, fertility concerns, and examination findings.

The evaluation aims to determine:

• Whether a varicocele is present.
• Its severity.
• Whether it is affecting fertility or testicular function.
• Whether another condition is contributing to infertility.

MEDICAL HISTORY

Your healthcare provider may ask about:

• Duration of infertility.
• Previous pregnancies.
• Scrotal pain.
• Previous scrotal injuries.
• Childhood undescended testes.
• Previous infections.
• Surgery involving the groin or scrotum.
• Occupational exposures.
• Lifestyle factors.
• Sexual function.
• Current medications.

A detailed history helps identify additional factors that may influence fertility.

PHYSICAL EXAMINATION

Physical examination remains the cornerstone of diagnosis.

The examination is usually performed:

• While standing.
• Occasionally while lying down.
• With and without the Valsalva maneuver.

The doctor evaluates:

• Testicular size.
• Consistency of the testes.
• Presence of enlarged veins.
• Tenderness.
• Signs of testicular atrophy.
• Associated scrotal abnormalities.

Experienced clinicians can diagnose most clinically significant varicoceles through physical examination alone.

SCROTAL ULTRASOUND

When the diagnosis is uncertain or further evaluation is needed, a scrotal ultrasound with color Doppler imaging may be performed.

Ultrasound helps assess:

• Diameter of the veins.
• Blood flow direction.
• Venous reflux.
• Testicular size.
• Testicular blood supply.
• Other scrotal abnormalities.

Color Doppler ultrasound is particularly useful for confirming clinically suspected varicoceles and excluding alternative diagnoses such as hydroceles, epididymal cysts, or testicular masses.

SEMEN ANALYSIS

For men being evaluated for infertility, a semen analysis is one of the most important investigations.

Typical abnormalities associated with clinically significant varicoceles may include:

• Reduced sperm concentration.
• Poor sperm motility.
• Increased abnormal sperm morphology.
• Elevated sperm DNA fragmentation.
• Reduced total motile sperm count.

Because semen quality varies naturally, at least two semen analyses obtained several weeks apart are often recommended before making treatment decisions.

HORMONE TESTING

Hormonal evaluation is not required for every man with a varicocele.

However, it may be recommended when there are symptoms or signs of hormonal dysfunction, abnormal semen analysis results, or testicular atrophy.

Tests may include:

• Total testosterone.
• Follicle-stimulating hormone (FSH).
• Luteinizing hormone (LH).
• Prolactin.
• Thyroid-stimulating hormone (TSH), when clinically indicated.

These investigations help identify coexisting endocrine disorders that may contribute to infertility.

WHO SHOULD RECEIVE TREATMENT?

Treatment is not necessary for every varicocele.

Current clinical guidelines generally recommend considering treatment for men who have:

• A clinically palpable varicocele.
• Infertility.
• At least one abnormal semen parameter.
• A female partner with reasonable fertility potential or a treatable fertility condition.

Treatment may also be appropriate for men with:

• Persistent scrotal pain that does not respond to conservative measures.
• Progressive testicular shrinkage, particularly in adolescents.
• Selected men with low testosterone and a clinically significant varicocele, although this should be individualized.

WHO MAY BE OBSERVED WITHOUT SURGERY?

Observation rather than immediate treatment is often appropriate for:

• Men with normal semen analysis and no fertility concerns.
• Men without symptoms.
• Men with subclinical varicoceles detected only on ultrasound.
• Older men who are not planning future fertility and have no discomfort.

These individuals may simply require periodic follow-up, particularly if future fertility becomes a consideration.

THE IMPORTANCE OF INDIVIDUALIZED DECISION-MAKING

The decision to treat a varicocele should always be individualized.

Factors considered include:

• Age.
• Fertility goals.
• Severity of the varicocele.
• Semen analysis results.
• Symptoms.
• Testicular size.
• Female partner's age and fertility status.
• Overall reproductive plan.

A careful discussion with a urologist or fertility specialist helps determine whether treatment is likely to provide meaningful benefit.

TREATMENT OF VARICOCELE

Not every man with a varicocele requires treatment. The decision to treat depends on several factors, including the severity of symptoms, fertility goals, semen analysis results, testicular size, and the fertility status of the female partner.

For men with infertility, persistent pain, progressive testicular shrinkage, or abnormal semen parameters, treatment may improve reproductive outcomes and quality of life.

The primary goal of treatment is to interrupt the abnormal veins, thereby eliminating backward blood flow (venous reflux), reducing testicular temperature, improving blood circulation, and creating a healthier environment for sperm production.

Several treatment options are available.

MICROSURGICAL VARICOCELECTOMY

Microsurgical varicocelectomy is widely regarded as the preferred surgical technique for most men with clinically significant varicoceles because it offers excellent success rates with relatively low complication and recurrence rates.

The procedure is usually performed through a small incision in the groin or just below it using a high-powered operating microscope.

The microscope allows the surgeon to:

• Clearly identify enlarged veins.
• Preserve the testicular artery.
• Protect lymphatic vessels.
• Avoid injury to the vas deferens.
• Reduce the risk of complications.

Because of this enhanced visualization, microsurgical repair is associated with better outcomes than many traditional techniques.

BENEFITS OF MICROSURGICAL REPAIR

Compared with older surgical approaches, microsurgical varicocelectomy generally offers:

• Lower recurrence rates.
• Lower risk of hydrocele formation.
• Better preservation of testicular blood supply.
• Faster recovery.
• Improved semen parameters in appropriately selected patients.
• Better postoperative comfort.

For these reasons, many fertility specialists consider it the gold standard for varicocele repair.

LAPAROSCOPIC VARICOCELECTOMY

Laparoscopic surgery is another option, although it is used less frequently than microsurgical repair for routine varicocele treatment.

During laparoscopic surgery:

• Small incisions are made in the abdomen.
• A camera is inserted.
• Specialized instruments are used to clip or divide the affected veins.

Potential advantages include:

• Treatment of bilateral varicoceles through the same procedure.
• Good visualization of abdominal structures.

However, because it involves entering the abdominal cavity, laparoscopic surgery may carry risks associated with minimally invasive abdominal procedures and is generally reserved for selected cases.

PERCUTANEOUS VARICOCELE EMBOLIZATION

Percutaneous embolization is a minimally invasive procedure performed by an interventional radiologist.

Instead of making a surgical incision, a small catheter is inserted into a vein, usually in the groin or neck, and guided to the abnormal testicular vein using imaging guidance.

Tiny coils or a special embolic agent are then placed inside the vein to block abnormal blood flow.

ADVANTAGES OF EMBOLIZATION

Potential benefits include:

• No surgical incision in the scrotum.
• Short recovery period.
• Less postoperative discomfort for some patients.
• Return to normal activities relatively quickly.

However, embolization may not be technically possible in every patient, and availability depends on local expertise.

CONSERVATIVE MANAGEMENT

Men who do not require immediate surgery may be managed conservatively.

This may include:

• Observation with periodic follow-up.
• Repeat semen analyses when fertility is desired.
• Pain management when necessary.
• Scrotal support during physical activity.
• Avoiding prolonged standing if symptoms worsen.
• Lifestyle modifications that support reproductive health.

Observation is appropriate for many men with normal semen analyses and no fertility concerns.

WHAT HAPPENS AFTER SURGERY?

Most varicocele repairs are performed as day-case procedures, meaning patients usually return home on the same day.

After surgery, mild discomfort, swelling, or bruising around the incision site is common and generally improves within a few days.

Patients are typically advised to:

• Keep the surgical area clean and dry.
• Wear supportive underwear or an athletic supporter if recommended.
• Avoid strenuous exercise for several weeks.
• Avoid heavy lifting during the early recovery period.
• Resume sexual activity only after receiving clearance from their surgeon.

Most men return to office-based work within several days, while physically demanding jobs may require a longer recovery period.

WHEN DOES SPERM QUALITY IMPROVE?

One of the most important questions couples ask is:

"How soon will fertility improve?"

Because sperm require approximately 70–90 days to develop, improvements are not immediate.

Most studies show that semen parameters begin to improve within three to six months after successful repair.

Maximum improvement may continue for 6 to 12 months in some men.

Repeat semen analyses are commonly performed at regular intervals to monitor progress.

DOES VARICOCELE REPAIR IMPROVE PREGNANCY RATES?

For appropriately selected infertile men with:

• A clinically palpable varicocele.
• Abnormal semen analysis.
• A female partner with reasonable fertility potential,

repair may increase the likelihood of:

• Improved semen quality.
• Natural conception.
• Better outcomes with assisted reproductive techniques.

However, pregnancy depends on many additional factors, including:

• Female age.
• Egg quality.
• Ovulation.
• Fallopian tube function.
• Uterine health.
• Timing of intercourse.

Therefore, surgery cannot guarantee pregnancy.

CAN VARICOCELE REPAIR IMPROVE TESTOSTERONE?

Emerging evidence suggests that some men experience modest improvements in testosterone levels following successful varicocele repair, particularly those with clinically significant varicoceles and lower testosterone before surgery.

Potential benefits may include:

• Improved energy levels.
• Better libido.
• Enhanced sexual well-being.
• Improved overall quality of life.

Not every patient experiences hormonal improvement, and testosterone should be reassessed after recovery if clinically indicated.

POSSIBLE COMPLICATIONS

Varicocele repair is generally safe when performed by experienced surgeons.

Nevertheless, as with any medical procedure, complications can occur.

Possible complications include:

• Bleeding.
• Infection.
• Persistent pain.
• Hydrocele (fluid collection around the testicle).
• Injury to the testicular artery.
• Injury to surrounding structures.
• Recurrence of the varicocele.
• Persistent infertility despite technically successful surgery.

Fortunately, serious complications are uncommon, particularly with microsurgical techniques.

RECURRENCE OF VARICOCELE

Although treatment is usually successful, a varicocele may occasionally recur.

Recurrence rates vary depending on:

• Surgical technique.
• Surgeon experience.
• Individual anatomy.

Microsurgical repair generally has the lowest recurrence rates among commonly used techniques.

If recurrence occurs, further evaluation is needed to determine whether additional treatment is appropriate.

LIFESTYLE MEASURES AFTER TREATMENT

Successful surgery should be accompanied by healthy lifestyle habits that support sperm production and overall reproductive health.

Recommended measures include:

• Stopping smoking.
• Limiting alcohol consumption.
• Maintaining a healthy body weight.
• Eating a balanced Mediterranean-style diet.
• Exercising regularly.
• Sleeping 7–9 hours each night.
• Managing chronic medical conditions effectively.
• Avoiding anabolic steroids and recreational drugs.
• Reducing prolonged exposure to excessive heat, such as frequent hot tubs and saunas.

These measures help optimize fertility while supporting long-term health.

FOLLOW-UP IS ESSENTIAL

Regular follow-up allows healthcare providers to monitor:

• Recovery from surgery.
• Improvement in semen parameters.
• Resolution of pain.
• Testicular growth in adolescents.
• Hormone levels when indicated.
• Progress toward pregnancy.

Couples should maintain realistic expectations and continue working closely with their fertility specialist throughout the recovery period.

FREQUENTLY ASKED QUESTIONS (FAQs)

What is a varicocele?

A varicocele is an enlargement of the veins within the scrotum caused by abnormal blood flow through the pampiniform venous plexus. It is similar to varicose veins in the legs and is one of the most common treatable causes of male infertility.

Does every varicocele cause infertility?

No.

Most men with a varicocele are able to father children naturally and never develop fertility problems.

A varicocele only becomes clinically significant when it contributes to:

• Abnormal semen parameters.
• Testicular shrinkage.
• Persistent scrotal pain.
• Reduced testosterone production in some men.
• Difficulty achieving pregnancy.

Many men with small varicoceles require no treatment.

Can a varicocele disappear on its own?

No.

A varicocele usually does not resolve spontaneously.

Once the abnormal veins have developed, they generally remain unless treated surgically or by embolization.

However, many stable, asymptomatic varicoceles simply require observation rather than intervention.

Does a varicocele always need surgery?

No.

Treatment depends on the individual's circumstances.

Surgery is generally considered when a man has:

• A clinically palpable varicocele.
• Infertility.
• At least one abnormal semen parameter.
• Persistent scrotal pain despite conservative management.
• Progressive testicular shrinkage, particularly in adolescents.

Men with normal semen analyses, no symptoms, and no fertility concerns are often managed conservatively.

Which operation is best?

For most men, microsurgical varicocelectomy is considered the preferred surgical technique because it offers:

• High success rates.
• Low recurrence rates.
• Low complication rates.
• Better preservation of arteries and lymphatic vessels.

Percutaneous embolization is another effective option in selected patients, particularly where expertise is available.

The best treatment should be individualized after discussion with a urologist or fertility specialist.

How long does recovery take?

Recovery varies depending on the treatment performed.

Most men:

• Return home the same day.
• Resume light daily activities within a few days.
• Return to office work within several days.
• Resume strenuous physical activity after several weeks, according to their surgeon's advice.

Complete internal healing takes longer than the visible skin incision.

When will sperm improve after surgery?

Because sperm development takes approximately 70–90 days, semen quality usually does not improve immediately.

Most men begin showing measurable improvement within 3–6 months, although continued improvement may occur for up to 12 months.

Regular follow-up semen analyses help monitor recovery.

Will surgery guarantee pregnancy?

No.

Varicocele repair may improve sperm quality and increase the likelihood of natural conception in appropriately selected men, but pregnancy depends on many additional factors, including:

• Female age.
• Egg quality.
• Ovulation.
• Fallopian tube patency.
• Uterine health.
• Frequency and timing of intercourse.
• Other male fertility factors.

Some couples may still require assisted reproductive technologies such as IUI, IVF, or ICSI after surgery.

Can a varicocele return after treatment?

Yes, although recurrence is uncommon when surgery is performed by experienced surgeons using microsurgical techniques.

The risk of recurrence depends on:

• Surgical method.
• Individual anatomy.
• Completeness of vein ligation or embolization.
• Surgeon experience.

If symptoms or infertility persist after treatment, reassessment may be necessary.

Can a varicocele reduce testosterone?

Yes.

Some men with clinically significant varicoceles have lower testosterone levels because the condition may impair the function of the Leydig cells that produce testosterone.

Research suggests that testosterone levels may improve after successful repair in selected patients, although not every man experiences this benefit.

Should adolescents with varicoceles be treated?

Not all adolescents require surgery.

Treatment is generally considered when there is:

• Progressive testicular shrinkage.
• Persistent pain.
• Significant differences in testicular size.
• Abnormal semen analysis in older adolescents, where testing is appropriate.

Regular follow-up is important because early intervention may help preserve future fertility in selected cases.

FINAL EVIDENCE-BASED VERDICT

Varicocele is one of the most common identifiable and potentially treatable causes of male infertility. It can impair fertility through several mechanisms, including increased scrotal temperature, oxidative stress, reduced oxygen delivery, hormonal disruption, and sperm DNA damage. However, the presence of a varicocele alone does not mean that a man is infertile or requires treatment.

Current clinical evidence supports treatment for carefully selected men with a clinically palpable varicocele, abnormal semen parameters, infertility, persistent pain, or progressive testicular atrophy. In these individuals, repair may improve semen quality, reduce sperm DNA fragmentation, increase the chances of natural conception, and improve the success of assisted reproductive treatments.

Microsurgical varicocelectomy remains the preferred treatment for most patients because of its excellent success profile and low complication rate. Percutaneous embolization is an effective alternative in appropriate circumstances. Decisions regarding treatment should always be individualized and made in consultation with a healthcare professional experienced in male reproductive medicine.

PRACTICAL RECOMMENDATIONS FOR MEN WITH A VARICOCELE

If you have been diagnosed with a varicocele and hope to father children, consider the following evidence-based recommendations:

• Arrange a comprehensive evaluation with a urologist or fertility specialist.
• Obtain at least two semen analyses if fertility is a concern.
• Consider hormone testing if symptoms of low testosterone are present.
• Maintain a healthy body weight.
• Follow a Mediterranean-style diet rich in fruits, vegetables, whole grains, legumes, fish, nuts, and healthy fats.
• Stop smoking and avoid vaping.
• Limit alcohol consumption.
• Avoid anabolic steroids and recreational drugs.
• Exercise regularly while avoiding excessive heat exposure to the scrotum.
• Wear supportive underwear if recommended for comfort.
• Attend scheduled follow-up appointments after treatment.
• Discuss fertility treatment options early if pregnancy has not occurred despite appropriate management.

KEY TAKEAWAYS

• Varicocele is one of the most common treatable causes of male infertility.
