When couples face fertility challenges, male factors are involved nearly 40% of the time. One of the most common yet overlooked causes is varicocele—a condition that affects the veins in the scrotum and can have a significant impact on male fertility.

But what exactly is a varicocele? How does it affect sperm health? And when should you consider treatment? Let’s explore this often-misunderstood condition and its role in male reproductive health.

What Is a Varicocele?

A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins that occur in the legs. These veins are part of the spermatic cord, which helps transport blood to and from the testicles.

Varicoceles occur when valves inside these veins don’t function properly, causing blood to pool and veins to dilate. This can raise the temperature in the scrotum and impair testicular function, key factors that affect fertility.

How Common Is Varicocele?

Varicoceles are relatively common and affect about 15% of all men. However, the incidence is much higher in men dealing with fertility problems—up to 40% of men with infertility have a varicocele.

Interestingly, varicoceles usually develop during puberty and are more common on the left side due to anatomical differences.

How Does Varicocele Impact Fertility?

Here’s how a varicocele can interfere with male fertility:

• Elevated testicular temperature: A varicocele can cause poor blood drainage, increasing the heat in the scrotum and reducing sperm production and quality.
• Oxidative stress: Increased levels of reactive oxygen species can damage sperm DNA.
• Low testosterone production: In some men, varicoceles impair hormone production, affecting libido and overall fertility.
• Poor sperm parameters: Men with varicoceles often have lower sperm count, reduced motility (movement), and abnormal morphology (shape).

Not all varicoceles cause infertility, but when they do, treatment can significantly improve the chances of conception.

Symptoms of a Varicocele

In many cases, varicoceles don’t cause noticeable symptoms. However, some men may experience:

• A dull ache or discomfort in the scrotum, especially after standing or exercising
• A feeling of heaviness in the testicles
• Visible or enlarged veins in the scrotum
• Shrinking of the affected testicle
• Difficulty in conceiving despite trying for a year or more

If you’re experiencing any of these symptoms, it’s best to get evaluated by a urologist.

How Is Varicocele Diagnosed?

A varicocele is often detected during a physical examination. Your doctor may also recommend:

• Scrotal ultrasound – to confirm the diagnosis and assess the size of the veins
• Semen analysis – to evaluate sperm count, motility, and morphology
• Hormone tests – to check testosterone and FSH levels if fertility is a concern

When to Treat a Varicocele?

Treatment is typically recommended in the following situations:

• If there is documented infertility and abnormal semen analysis
• Presence of testicular pain or discomfort
• Evidence of testicular shrinkage
• Elevated scrotal temperature affecting sperm health
• In adolescents with progressive testicular atrophy

Treatment Options for Varicocele

The most common treatment for varicocele is varicocelectomy—a surgical procedure to tie off the affected veins, redirecting blood flow to normal veins.

Minimally invasive techniques include:

• Microsurgical varicocelectomy – high success rate and low recurrence
• Laparoscopic surgery – useful for bilateral varicoceles
• Percutaneous embolization – a non-surgical, catheter-based procedure

These treatments can improve sperm quality and increase the chances of natural conception or success with assisted reproductive techniques.

Frequently Asked Questions (FAQs)

1. Can a varicocele cause permanent infertility?

Not always. Early diagnosis and treatment can restore fertility in many men. However, delayed intervention may lower the chances.

2. Does varicocele surgery guarantee pregnancy?

It significantly improves sperm parameters in most men, but success also depends on other fertility factors in both partners.

3. Is varicocele surgery painful?

Modern surgical methods are minimally invasive. Most men experience mild discomfort and recover within a few days.

4. Can I prevent varicocele from developing?

There is no guaranteed prevention. However, early detection through routine exams can help avoid long-term effects on fertility.

5. Is treatment necessary if I have no symptoms?

If you’re not planning to have children and have no symptoms, treatment may not be necessary. However, for couples trying to conceive, it’s worth addressing.
