A varicocele is one of the most common causes of male infertility and testicular discomfort, affecting about 15% of all men and up to 40% of men evaluated for infertility. It refers to an abnormal enlargement of the veins within the scrotum (the loose pouch of skin that holds the testicles), similar to varicose veins that occur in the legs.
While some men with varicocele may experience no symptoms, others may suffer from dull pain, heaviness, or fertility issues due to reduced sperm quality. Fortunately, advancements in medical and surgical techniques have made varicocele treatment highly effective and minimally invasive.
This article explores everything you need to know about varicocele treatment, including its causes, symptoms, diagnosis, medical and surgical options, recovery, and success rates.
What Is a Varicocele?
A varicocele is the enlargement of the pampiniform plexus, a network of veins that drain the testicles. These veins normally help regulate testicular temperature — which must be slightly lower than body temperature for optimal sperm production. When these veins become enlarged, blood flow is impaired, leading to increased scrotal temperature and oxidative stress. Over time, this can affect testicular function and sperm production.
Varicoceles are more common on the left side due to the anatomical differences in how the left testicular vein drains into the left renal vein, which has higher pressure compared to the right side. However, in some cases, varicoceles can be bilateral (affecting both sides).
Causes of Varicocele
The exact cause of varicoceles is not always clear, but several factors contribute to their formation:
Valve Malfunction in Veins:
Veins in the scrotum have one-way valves that allow blood to flow from the testicles toward the heart. When these valves fail, blood flows backward (reflux), causing pooling and vein enlargement.
Anatomical Factors:
The left testicular vein drains into the left renal vein at a perpendicular angle, creating more pressure and making the left side more prone to varicocele.
Increased Abdominal Pressure:
Activities or conditions that increase abdominal pressure, such as heavy lifting, chronic constipation, or obesity, may contribute to varicocele formation.
Genetic Predisposition:
Some men may have a genetic weakness in their vein walls or valves, making them more susceptible.
Symptoms of Varicocele
Many men with varicocele have no symptoms, and the condition is often discovered during a routine physical examination or infertility evaluation. However, when symptoms occur, they may include:
A dull, aching pain in the scrotum
A feeling of heaviness or dragging sensation in the testicle
Visible or palpable enlarged veins ("bag of worms" appearance)
Swelling or asymmetry in the scrotum
Testicular atrophy (shrinkage of the affected testicle)
Reduced sperm count, motility, or quality
Infertility or difficulty conceiving
Pain typically worsens with prolonged standing, physical exertion, or heat exposure and improves when lying down.
Diagnosis of Varicocele
Diagnosis involves a combination of physical examination and imaging tests:
- Physical Examination
The doctor will examine the scrotum while the patient is standing and may ask him to perform the Valsalva maneuver (taking a deep breath and bearing down) to make the varicocele more prominent. Varicoceles are classified based on their size and visibility:
Grade I: Small, palpable only during Valsalva maneuver
Grade II: Moderate, palpable without Valsalva maneuver
Grade III: Large, visible through the scrotal skin
- Scrotal Ultrasound
A Doppler ultrasound is often used to confirm the diagnosis and assess the severity. It measures blood flow and vein diameter. Ultrasound can also help rule out other causes of scrotal swelling or pain.
- Semen Analysis
In men concerned about fertility, semen analysis helps evaluate sperm count, motility, and morphology (shape). Varicoceles often lead to abnormal sperm parameters.
When Does a Varicocele Need Treatment?
Not all varicoceles require treatment. Many men live with small, asymptomatic varicoceles without any problems. However, treatment is recommended in the following situations:
Infertility:
When a man with a palpable varicocele has abnormal semen analysis and infertility, treatment can significantly improve sperm quality and chances of conception.
Testicular Atrophy:
If the affected testicle shows signs of shrinkage compared to the other side, treatment can help prevent further damage.
Pain or Discomfort:
Persistent or severe pain not relieved by conservative measures warrants surgical correction.
Abnormal Testosterone Levels:
In some cases, varicocele repair can improve testosterone production.
Treatment Options for Varicocele
Varicocele treatment focuses on blocking the affected veins to redirect blood flow through normal veins, relieving pressure, and restoring proper testicular function. Treatment can be surgical or non-surgical, depending on severity, symptoms, and patient preference.
- Conservative Management
For men with mild or asymptomatic varicoceles, observation and lifestyle modifications may be enough. Conservative approaches include:
Avoiding heavy lifting and prolonged standing
Wearing supportive underwear or an athletic supporter to relieve discomfort
Using pain relievers (NSAIDs like ibuprofen) for occasional pain
Regular follow-ups to monitor testicular size and function
However, conservative management will not cure varicocele — it only helps manage symptoms.
- Surgical Treatment (Varicocelectomy)
Varicocelectomy is the most common and effective treatment for symptomatic or fertility-related varicoceles. It involves ligating (tying off) the enlarged veins to prevent reflux. There are several surgical techniques available:
a. Open Surgery (Microsurgical Varicocelectomy)
Procedure:
The surgeon makes a small incision in the lower abdomen or groin and uses a microscope to identify and tie off the dilated veins while preserving arteries and lymphatic vessels.
Advantages:
Highest success rate
Lowest recurrence and complication rates
Often performed as an outpatient procedure
Recovery:
Most patients return to normal activity within 2–3 days and resume exercise within 1–2 weeks.
b. Laparoscopic Varicocelectomy
Procedure:
Small incisions are made in the abdomen to insert a laparoscope and surgical instruments. The affected veins are clipped or sealed.
Advantages:
Useful for bilateral varicoceles
Faster recovery than open surgery
Disadvantages:
Requires general anesthesia
Slightly higher complication risk than microsurgery
c. Subinguinal Varicocelectomy
Procedure:
Similar to open surgery but performed below the groin crease with minimal tissue disruption.
Advantages:
Minimally invasive
Less postoperative pain and faster recovery
Commonly performed using microsurgical techniques
- Non-Surgical Treatment (Percutaneous Embolization)
Varicocele embolization is a minimally invasive procedure performed by an interventional radiologist. It involves inserting a thin catheter into a vein in the groin or neck and guiding it to the affected testicular vein under imaging guidance. Coils, balloons, or a sclerosing agent are then used to block blood flow through the varicose veins.
Advantages:
No incisions or stitches
Local anesthesia only
Quick recovery (usually back to work the next day)
Low risk of infection
Disadvantages:
Slightly higher recurrence rate than microsurgery
Requires radiological expertise
May not be suitable if veins are too small or twisted for catheter access
Recovery After Varicocele Treatment
Recovery depends on the type of treatment performed. In most cases, patients can resume normal activities within a few days. Here’s a general recovery timeline:
First 24–48 hours: Mild pain and swelling; managed with ice packs and pain relievers.
First week: Avoid strenuous activity, heavy lifting, and sexual intercourse.
1–2 weeks: Most patients can return to full normal activity.
3 months: Follow-up semen analysis to check sperm improvement.
Most men experience significant symptom relief and improved sperm quality within 3 to 6 months post-treatment.
Possible Complications
Although rare, some complications can occur after varicocele treatment:
Mild scrotal pain or swelling
Hydrocele formation (fluid accumulation around the testicle)
Infection at the incision site
Testicular artery injury (extremely rare with microsurgery)
Recurrence of varicocele
Microsurgical techniques have the lowest complication rate and are preferred for long-term success.
Varicocele and Fertility
Varicoceles are a leading cause of male infertility. The condition can negatively affect sperm count, motility, and morphology, as well as increase DNA fragmentation due to oxidative stress.
Treating varicocele has shown significant improvements in:
Sperm concentration
Sperm motility
Morphology (normal-shaped sperm)
Testosterone levels
Pregnancy rates (natural and assisted conception)
According to studies, pregnancy rates after varicocele repair range from 30% to 50% within one year — especially when female partners are under 35 years of age.
Prevention and Lifestyle Management
While not all varicoceles can be prevented, maintaining good vascular health and lifestyle habits may reduce the risk or slow progression:
Maintain a healthy weight
Avoid excessive heat exposure (hot tubs, tight clothing)
Exercise regularly but avoid overexertion
Manage constipation to reduce intra-abdominal pressure
Avoid smoking and alcohol abuse
Prognosis and Long-Term Outlook
The prognosis after varicocele treatment is excellent. Most patients experience complete pain relief and improved fertility outcomes. Microsurgical varicocelectomy has a success rate exceeding 90%, and recurrence is uncommon.
Testosterone levels often improve, and testicular size may recover over time, particularly in adolescents. Regular follow-up with semen analysis and testicular examinations ensures long-term success.
Conclusion
Varicocele is a common yet treatable condition that can impact male fertility and testicular health. Whether managed through microsurgical varicocelectomy or minimally invasive embolization, modern treatment options offer high success rates with minimal risks.
Early diagnosis and timely intervention are crucial — especially for men experiencing pain, testicular shrinkage, or fertility issues. With proper medical guidance, most men can achieve significant improvement in both comfort and reproductive outcomes.
If you suspect you have symptoms of a varicocele or are facing difficulties with fertility, consulting a qualified urologist or andrologist is the best first step toward effective treatment and recovery.
