Spermatocele

Name: Spermatocele
Creator: Dr. Marinos Vasilas

My Clinical Approach

For spermatocele I follow a conservative approach. I do not operate on asymptomatic spermatoceles, especially in young patients who wish to father children, due to the risk of epididymal injury.

I always confirm the diagnosis with ultrasound and rule out other pathology (testicular cyst, tumor, hydrocele).

When we choose surgery, I use microsurgical technique with high magnification to protect the epididymal ducts.

What is Spermatocele?

Spermatocele is a cyst that forms in the head of the epididymis and contains clear fluid with sperm. It differs from a simple epididymal cyst only in content.

Frequency: 30% of men on ultrasound
Usually asymptomatic
Size: from a few millimeters to several centimeters
Often bilateral
Not associated with cancer
Usually does not affect fertility

Differential Diagnosis from Hydrocele

• Located above/behind the testis
• Distinct and separate from the testis
• Clear fluid with sperm
• Usually small (<2 cm)

Hydrocele

• Surrounds the testis
• Testis cannot be palpated separately
• Serous fluid
• Can become large

Symptoms

Usually asymptomatic (incidental finding)
Painless mass above the testis
Sensation of heaviness (in large ones)
Rarely mild pain
Cosmetic concern
Palpable on self-examination

Diagnosis

Clinical examination: smooth, mobile mass separate from the testis
Transillumination: positive
Scrotal ultrasound (confirmatory)
• Anechoic cyst with thin walls
• Located in the epididymal head
• Normal testis
No blood tests required

Treatment

Observation (most common option)

For asymptomatic spermatoceles. Annual ultrasound size monitoring.

Spermatocelectomy

• Meticulous cyst removal without rupture
• Microsurgical technique (epididymal duct protection)
• Scrotal approach 3-4 cm
• Duration: 30-45 minutes
• Recurrence: 5-15%

Sclerotherapy (selected)

Aspiration + injection of sclerosing agent (polidocanol, tetracycline). High recurrence 30-50%.

Caution in young patients: surgical removal may cause obstruction of epididymal ducts and infertility. We discuss thoroughly before deciding.

Recovery

Same-day discharge
Ice packs first 24 hours
Scrotal support (special underwear)
Return to light activities in 3-7 days
Return to work in 1 week
Sports activities in 3-4 weeks
Sexual activity in 2-3 weeks

Fertility & Complications

Hematoma: 2-5%
Wound infection: 1-2%
Recurrence: 5-15%
Epididymal duct obstruction: 1-3%
Infertility (bilateral procedure): <5%
Chronic pain: <3%
Testicular injury: rare

Frequently Asked Questions (FAQ)

Does spermatocele affect fertility?

Spermatocele usually does not affect fertility. However, surgical removal (spermatocelectomy) carries a risk of epididymal duct injury and obstruction; therefore caution is required in young patients who wish to father children.

How is it differentiated from hydrocele?

Spermatocele is an epididymal cyst with sperm content, located separately from the testis (above/behind it). Hydrocele surrounds the testis. Ultrasound easily distinguishes them.

When is surgery needed?

Only when it causes symptoms: pain, bothersome size, cosmetic concern. Small asymptomatic spermatoceles are observed.

Is spermatocele cancer?

No, it is a benign cystic lesion. It does not progress to cancer. However, every newly palpated scrotal mass should be evaluated with ultrasound.

How long is recovery?

Return to light activities in 3-7 days, work in 1 week, sports in 3-4 weeks.
