Understanding When an Operation Is Really Needed

A diagnosis of varicocele often creates an immediate question in a man's mind: “Do I need surgery?”

The answer is not the same for every patient.

Varicocele is an enlargement of veins around the testicle, most commonly on the left side. Some men have a varicocele for years without significant symptoms or fertility problems, while others may experience discomfort, reduced testicular development, abnormal semen parameters, or difficulty achieving pregnancy. Mayo Clinic notes that many varicoceles require no treatment at all, while surgery may become relevant in selected patients with infertility, persistent pain, abnormal sperm findings, or impaired testicular development. Mayo Clinic

This is why the question should not simply be “Varicocele—surgery or no surgery?” The more useful question is:

“Is this varicocele actually causing a clinically important problem that is likely to benefit from treatment?”

In our latest Saira Health Care educational video, we discuss this important question in detail.

What Is a Varicocele?

A varicocele is an abnormal enlargement of veins within the scrotum that drain blood from the testicle.

It is somewhat similar in principle to varicose veins in the legs. When the valves or drainage system in these veins do not function efficiently, blood can pool and the veins may become enlarged.

Varicocele is more common on the left side because of differences in the anatomy of the testicular venous system. It may develop gradually and frequently produces no symptoms.

When symptoms do occur, a man may notice a dull or aching discomfort, a feeling of heaviness, enlarged veins above the testicle, differences in testicular size, or fertility problems. Importantly, however, not every man with a varicocele is infertile and not every varicocele causes pain. Mayo Clinic

Does Every Varicocele Need Surgery?

No.

This is the most important message for patients.

A varicocele detected during an examination or ultrasound does not automatically create an indication for surgery.

Many varicoceles can simply be observed, particularly when the patient has no significant pain, no fertility concern, no evidence of impaired testicular development, and no clinically important abnormality in semen parameters.

Current AUA/ASRM male-infertility guidance specifically recommends against varicocelectomy for a nonpalpable varicocele detected only by imaging. In other words, finding a very small “subclinical” varicocele on ultrasound is not, by itself, a reason for an operation. ASRM

European guidance similarly reports that randomized studies have not shown a meaningful fertility benefit from treating subclinical varicocele or treating men who primarily have normal semen parameters. Uroweb

Therefore, surgery should be a clinical decision, not an automatic response to the word “varicocele” appearing on an ultrasound report.

When May Varicocele Surgery Be Considered?

For an adult man, the decision generally depends upon the combination of physical examination, symptoms, fertility goals, semen analysis and other reproductive findings.

Current AUA/ASRM guidance states that surgical varicocelectomy should be considered in men who are attempting to conceive, have a palpable varicocele, infertility, and abnormal semen parameters, with separate considerations applying to azoospermic patients. ASRM

Situations in which treatment may therefore be considered include:

• A clinically detectable varicocele in a man experiencing infertility together with abnormal semen parameters.
• Persistent testicular pain or discomfort that is reasonably attributed to the varicocele and has not improved with conservative measures.
• Evidence of impaired testicular growth or significant testicular asymmetry, particularly in adolescents or young men.
• Selected fertility situations in which a reproductive specialist believes repairing a clinically significant varicocele may improve the couple's overall fertility strategy.
• Selected men with other fertility abnormalities after complete counselling about the expected benefits, limitations, treatment delay and alternatives.

The final decision must be individualized.

Varicocele and Male Infertility

Varicocele is one of the recognized potentially correctable conditions associated with male infertility.

Possible mechanisms include increased testicular temperature, altered blood flow, oxidative stress and changes in the environment required for normal sperm production.

However, the presence of a varicocele does not prove that it is the cause of infertility.

A couple may have several fertility factors at the same time. For example, the male partner may have a varicocele and the female partner may have an age-related decline in ovarian reserve or another reproductive condition.

European guidance therefore emphasizes evaluating both partners, because the female partner's age and ovarian reserve can influence whether waiting for improvement after varicocele treatment is reasonable or whether assisted reproductive treatment may need to proceed sooner. Uroweb

This is especially important because varicocele surgery is not an instant fertility treatment.

Can Surgery Improve Sperm Count?

In appropriately selected infertile men with a clinical varicocele and abnormal semen parameters, treatment can improve semen findings in some patients.

The European Association of Urology reports evidence of improvement in sperm concentration and other semen parameters following varicocele repair in selected men. It also notes that improvement may take up to approximately two spermatogenic cycles, and spontaneous pregnancies after repair are commonly reported during the following months rather than immediately after treatment. Uroweb

This means that couples should consider the time factor before surgery.

For a younger couple without an urgent female fertility issue, waiting for potential improvement may sometimes be reasonable.

For a couple in which the female partner has reduced ovarian reserve or advancing reproductive age, delaying assisted reproduction for several months may have different implications.

The correct decision therefore belongs to the couple's complete fertility plan, not only to the man's ultrasound report.

What If My Semen Analysis Is Normal?

If a man has a varicocele but his semen parameters are normal, he has no significant discomfort, and there is no evidence of testicular damage, surgery is generally much less likely to provide a clear benefit.

The EAU evidence review reports no demonstrated advantage of treating men with subclinical varicocele or populations consisting mainly of men with normal semen parameters. Uroweb

This is why performing surgery “just because varicocele is present” may expose some men to unnecessary treatment.

Observation and periodic clinical review may be more appropriate.

What If the Varicocele Was Found Only on Ultrasound?

This situation is extremely common.

A patient undergoes Doppler ultrasound for mild discomfort or another reason and receives a report mentioning a “small varicocele.”

He may immediately become worried that surgery is necessary.

But a varicocele detected only on imaging and not palpable during proper physical examination is generally described as subclinical.

AUA/ASRM guidance explicitly advises clinicians not to recommend varicocelectomy for nonpalpable varicoceles detected solely by imaging. ASRM

Therefore:

Ultrasound finding alone ≠ automatic surgery.

The result must be correlated with examination, symptoms and fertility findings.

Why Physical Examination Matters

Varicocele is fundamentally a clinical diagnosis.

A healthcare professional generally examines the patient while standing and may ask him to perform a Valsalva maneuver—bearing down in a way that increases abdominal pressure—to make enlarged veins easier to detect.

Ultrasound can help when examination is uncertain, confirm anatomy, characterize the varicocele, or exclude other conditions. Mayo Clinic

But ultrasound should complement the clinical examination rather than automatically determine whether an operation is needed.

Varicocele Grades: Does a Higher Grade Automatically Mean Surgery?

Clinical varicoceles are sometimes categorized according to how easily the enlarged veins can be detected during examination.

A higher grade may represent a more obvious varicocele, but grade alone should not determine treatment.

Two men may both have the same grade of varicocele and yet need completely different management.

One may have normal semen analysis, no pain and no current fertility difficulty.

The other may have persistent infertility and repeatedly abnormal semen parameters.

Therefore, treatment decisions should consider the patient, not merely the grade.

Varicocele and Testicular Pain

Varicocele can sometimes cause a dull, aching or dragging discomfort.

Pain may become more noticeable after prolonged standing, exercise or toward the end of the day and may improve after lying down. Mayo Clinic

But testicular pain can also result from many other conditions.

For this reason, a man with scrotal pain should not automatically assume that the varicocele seen on ultrasound is responsible.

Doctors may need to exclude other possible causes before recommending varicocele surgery for pain.

Mayo Clinic also cautions that when surgery is performed primarily for pain, the pain may sometimes persist, change in character or even worsen. Mayo Clinic

Therefore, careful counselling before surgery is important.

What If the Varicocele Causes Only Mild Discomfort?

When fertility is not affected and discomfort is minor, conservative measures may sometimes be sufficient.

These can include appropriate scrotal support, modifying activities that clearly aggravate discomfort and, where medically appropriate, simple pain-relieving medicines under professional guidance.

Mayo Clinic similarly notes that men with mild discomfort who do not have fertility problems may sometimes manage symptoms conservatively. Mayo Clinic

If pain persists, worsens or changes significantly, medical reassessment is appropriate.

Varicocele in Adolescents and Young Men

Management in adolescents requires particular care because unnecessary surgery should be avoided.

The EAU guideline notes a significant risk of overtreatment because many adolescents with varicocele will later achieve normal fertility.

Preventive treatment is generally considered when there is documented deterioration in testicular growth on serial examination or Doppler ultrasound and/or abnormal semen findings when semen analysis is appropriate. Uroweb

Simply discovering a varicocele in a teenager does not automatically mean he requires surgery.

Monitoring testicular development may be appropriate in many cases.

What About Varicocele With Azoospermia?

Azoospermia means that no sperm are found in the ejaculate after appropriate laboratory examination.

This situation requires a much more detailed fertility evaluation.

For men with non-obstructive azoospermia (NOA) and a clinical varicocele, some studies have reported that sperm may appear in the ejaculate after varicocele treatment or that sperm-retrieval outcomes may improve.

However, the quality of this evidence is limited.

The EAU specifically states that available evidence is of low quality and that the risks and potential benefits should be fully discussed with men who have NOA and a clinically significant varicocele. Uroweb

AUA/ASRM guidance is similarly cautious and states that couples should be informed that there is no definitive evidence supporting varicocele repair before assisted reproductive treatment in men with clinical varicocele and NOA. ASRM

Therefore, a man with zero sperm plus varicocele should not automatically undergo surgery.

He requires proper evaluation of the cause of azoospermia first.

Is Varicocele Surgery a Guaranteed Cure for Infertility?

No.

Varicocele repair may improve semen parameters or fertility outcomes in appropriately selected men, but it does not guarantee:

pregnancy,

normal sperm count,

normal sperm motility,

restoration of fertility,

or avoidance of IVF/ICSI.

Infertility is influenced by both partners and often involves several biological factors.

Therefore, surgery should be offered with realistic expectations rather than guarantees.

How Is Varicocele Surgery Performed?

The basic aim of varicocele repair is to interrupt abnormal venous drainage so that blood is redirected through healthier veins.

Several techniques exist.

Microsurgical Varicocelectomy

This is performed using magnification to identify and close abnormal veins while attempting to preserve important arteries, lymphatic vessels and other structures.

Current EAU guidance reports that microsurgical repair generally has lower recurrence and complication rates than several other surgical techniques, although it requires specific microsurgical expertise. Uroweb

Laparoscopic Varicocelectomy

In laparoscopic surgery, instruments and a camera are inserted through small abdominal incisions to access and ligate the affected veins.

This remains a possible technique in appropriate situations.

Varicocele Embolization

Embolization is a minimally invasive radiological alternative rather than conventional open surgery.

A radiologist guides a catheter through the venous system and blocks the abnormal vein using coils or another embolizing material.

Mayo Clinic notes that embolization generally involves a relatively short recovery period. Mayo Clinic

The best technique depends upon anatomy, available expertise, previous procedures and the individual patient's circumstances.

What Are the Possible Risks of Surgery?

Although varicocele repair is commonly performed, no surgical procedure is completely risk-free.

Possible complications include recurrence or persistence of the varicocele, hydrocele or fluid accumulation around the testicle, infection, bleeding or hematoma, arterial injury, and persistent or altered pain.

Mayo Clinic specifically lists hydrocele, recurrence, infection, arterial damage, chronic testicular pain and hematoma among potential complications. Mayo Clinic

This is another reason surgery should be performed when there is a meaningful expected benefit rather than simply because a varicocele exists.

How Soon Can Sperm Improve After Surgery?

Sperm production takes time.

Patients should not expect a semen analysis performed a few days or weeks after surgery to show the final effect.

European guidance notes that improvement in semen parameters may take approximately two spermatogenic cycles, while spontaneous pregnancies after treatment may occur over the following six to twelve months. Uroweb

Follow-up semen analysis is therefore generally performed at clinically appropriate intervals.

Surgery or IVF/ICSI: Which Should Come First?

There is no universal answer.

The decision can depend on:

the man's semen findings,

the severity of the varicocele,

the duration of infertility,

previous fertility treatment,

the female partner's age,

her ovarian reserve,

other female fertility factors,

and how quickly the couple needs to proceed toward pregnancy.

A varicocele operation can potentially improve male fertility, but treatment requires recovery and time for sperm production to change.

If the female partner has significantly reduced ovarian reserve or age-related fertility concerns, waiting several months may not always be the best reproductive strategy.

The EAU specifically emphasizes considering the female partner's age and ovarian reserve when choosing between varicocele intervention and assisted reproductive approaches. Uroweb

This is why infertility should always be approached as a couple's evaluation.

When Might Surgery Not Be Necessary?

Surgery is often unnecessary when a man has an imaging-only subclinical varicocele, normal semen parameters without another significant indication, no fertility concern, minimal or no symptoms, and no evidence of impaired testicular development.

The key principle is:

Presence of varicocele does not equal need for surgery.

Current guidelines support treatment primarily when there is a clinically meaningful indication rather than treating every detected vein enlargement. ASRM

Do Medicines Cure Varicocele?

Medicines do not physically close or remove enlarged varicocele veins in the same way that surgery or embolization does.

Medical treatment may sometimes be used to address symptoms or associated health factors, but patients should be cautious about claims that any tablet, herbal product or supplement can guarantee permanent disappearance of a clinically significant varicocele.

At the same time, not every patient requires correction of the veins.

A man who does not have a surgical indication may be managed conservatively and monitored according to his individual circumstances.

This is an important distinction between managing a patient and promising to “remove” a varicocele.

What Tests Should Be Done Before Deciding?

A responsible decision about varicocele surgery may involve a detailed reproductive and medical history, examination by an appropriately qualified clinician, semen analysis—often repeated when abnormal—assessment of testicular size, and selected hormone or imaging studies when clinically indicated.

For an infertile couple, evaluation of the female partner should occur simultaneously.

The AUA/ASRM guideline recommends a reproductive history and one or more semen analyses in the initial male fertility evaluation and specialist assessment when abnormal semen findings are present. ASRM

The purpose is to answer a much more meaningful question than simply:

“Is varicocele present?”

The real question is:

“Is this varicocele clinically important for this particular patient?”

Saira Health Care's Message to Patients

At Saira Health Care, we encourage men to avoid both extremes.

Do not ignore persistent pain, testicular changes or infertility.

But also do not assume that every varicocele requires immediate surgery.

The appropriate pathway is:

Confirm the Diagnosis → Assess Symptoms → Evaluate Fertility → Perform Semen Analysis When Appropriate → Examine Testicular Health → Consider Both Partners → Decide Whether Intervention Offers Meaningful Benefit

A patient with a small asymptomatic varicocele and normal fertility should not necessarily be managed in the same way as a man with a palpable clinical varicocele, infertility and repeatedly abnormal semen parameters.

Treatment should always be individualized.
