🎧MSRA Podcast:Spermatocele – Clear, Painless & Often Missed

In this focused deepdive, we unpack everything you need to know about spermatoceles, also known as spermaticcysts — benign scrotal swellings that often go undetected until they'respotted by chance. Whether you're prepping for the MSRA or simply buildingclinical confidence, this is your concise, high-yield audio guide to masteringthe essentials.

🧠What You’ll Learn:

✅Definition

• A spermatocele is a benign, fluid-filled cyst that arises from the epididymis

• Typically containsmilky fluid and sperm

• Most are painless, soft, and distinct from the testicle

🧠 Tip: Think "sperm in a cell" → spermatocele.

⚠️Causes & RiskFactors

• Often due to epididymal duct obstruction

• Possibly linkedto:

 – Past scrotal surgery

 – Epididymitis or prior infection

 – Congenital abnormalities

 – Conditions like cystic fibrosis

🧠 Mnemonic: SCI-U

– Surgery

– Congenital / CF

– Inflammation

– Uncertain cause

🔬Pathophysiology

• Duct blockagecauses backflow of fluid + sperm

• Gradualaccumulation forms the cyst

• Can enlarge slowly but often asymptomatic

📋DifferentialDiagnoses

• 🧪 Hydrocele

• 🧬 Epididymal cyst (non-sperm)

• 🩸 Varicocele (bag of worms)

• ⚠️ Testicular tumour (must not be missed)

🧠 Mnemonic: HEVT – Hydrocele,Epididymal cyst, Varicocele, Tumour

📊Epidemiology

• Common, especiallyin middle-aged men

• Often foundincidentally on exam or imaging

• UK-specificprevalence unclear, but frequently encountered

🩺Clinical Features

• Usually asymptomatic

• May present as painless swelling or feeling of heaviness

• Located behind/above the testicle, in theepididymis

• Transilluminates on exam

🧠 Tip: Cystic = translucent; Solid = opaque

🧪Diagnosis

• Clinical exam + transillumination suggestive

• Confirmed by scrotal ultrasound:

 – Showswell-defined, hypoechoic, cystic lesion

 – Located in epididymal head

• Ultrasound rulesout tumour or other pathology

💉Management

• Asymptomatic → observe(no treatment needed)

• Symptomatic (pain/discomfort):

 – Consider spermatocelectomy (surgical excision)

 – ⚠️Risk to fertility if epididymal damage occurs

• Not first-line:

 – Aspiration

 – Sclerotherapy

  (both have higherrecurrence rates)

🧠 Younger men should be counselled on fertility riskbefore surgery

📉Complications (Rare)

• Infection or abscess formation

• Recurrence (post-surgery)

• Fertility issues if epididymal damage occurs

• Psychosocialdiscomfort due to lump

📈Prognosis

• Excellent

• Most remain stableor resolve

• Surgery typicallyresolves symptoms if needed

• Recurrence andserious complications are uncommon

💡Final Takeaway

Most spermatocelesare harmless and often go unnoticed — but regular testicular self-examination is vital. It improves self-awarenessand may aid early detection of more serious conditions like testicular cancer.
