The epididymis is a small, coiled tube found at the back of each testicle (testis) within the male reproductive system. It plays a crucial role in collecting, storing, and transporting sperm. The epididymis has three main parts:
- Head (caput) – The top part of the epididymis.
- Body (corpus) – The middle section.
- Tail (cauda) – The lower end that connects to the vas deferens.
A tumor in the head of the epididymis refers to an abnormal growth (either benign or malignant) located specifically in the upper section of the epididymis. Tumors in this region can be rare compared to other testicular or scrotal abnormalities, but they can still cause discomfort, pain, or other symptoms.
This guide will help you understand what epididymis head tumors are, why they happen, how they’re diagnosed, and the various treatment and prevention options.
Pathophysiology of the Epididymis
1. Structure
- Location: The epididymis is situated behind each testicle. The head of the epididymis is the widened, upper portion that sits close to the top of the testicle.
- Coiled Tubule: It’s made up of a tightly coiled duct (ductus epididymis). If stretched out, this duct can be many meters long.
- Epithelial Lining: The inner lining of the epididymis contains special cells that help nourish and protect sperm while they mature.
- Three Parts:
- Head (caput): Receives immature sperm from the testis.
- Body (corpus): Where sperm start to mature and gain motility (movement ability).
- Tail (cauda): Stores mature sperm until they are ready for ejaculation.
2. Blood Supply
- Testicular Artery: Primarily supplies blood to the testicle and branches to the epididymis.
- Cremasteric Artery: Can also supply some blood to the epididymis.
- Venous Drainage: Drains into the pampiniform plexus, which eventually carries blood into the testicular vein. Proper blood flow is critical for sperm health.
3. Nerve Supply
- Sympathetic Fibers: Arise from the testicular plexus, traveling along with blood vessels.
- Parasympathetic Fibers: Contribute to the regulation of smooth muscle contraction within the epididymis, helping in the movement of sperm.
- Sensory Innervation: Helps signal pain or discomfort if there is inflammation or a tumor.
4. Functions of the Epididymis
- Sperm Maturation: Newly produced sperm from the testis enter the epididymis where they mature and acquire the ability to move (motility).
- Storage: Stores mature sperm until they’re ready to be ejaculated.
- Transportation: Transports sperm from the testis to the vas deferens.
- Protection and Nourishment: Creates a specialized environment that keeps sperm healthy.
Types of Head of Epididymis Tumors
- Adenomatoid Tumor (benign): These are the most common benign tumors of the epididymis. They rarely spread but can cause a painless lump.
- Leiomyoma (benign): Originates from smooth muscle cells; uncommon but typically not cancerous.
- Cystadenoma (benign): Involves fluid-filled sacs that can develop in glandular tissue.
- Papillary Cystadenoma (benign): More specific type of cystic tumor, often associated with hereditary conditions like von Hippel-Lindau disease.
- Fibroma (benign): Tumor of fibrous tissue, very rare in the epididymis but possible.
- Lipoma (benign): Tumor consisting of fatty tissue; again, quite rare in the epididymis.
- Malignant Tumors (rare): Can include sarcomas, metastases from other cancers, or very rare primary carcinomas.
Benign tumors are far more common than malignant ones in the epididymis. However, any noticeable lump or swelling should be evaluated by a healthcare professional to rule out malignancy or other causes.
Causes or Risk Factors
- Genetic Predisposition: Some benign tumors, like papillary cystadenomas, can be linked to hereditary conditions (e.g., von Hippel-Lindau disease).
- Age: Middle-aged or older men might have a slightly higher risk for epididymal growths.
- Chronic Infections: Long-standing infections or inflammation (e.g., epididymo-orchitis) could theoretically contribute to tissue changes.
- Hormonal Imbalances: Abnormal hormone levels might influence the growth of certain tissues.
- Congenital Abnormalities: Born with structural variations in the reproductive tract that increase tumor risk.
- Occupational Exposures: Exposure to certain chemicals or radiation (though rare for epididymal tumors, this is a general risk factor for cancers).
- Testicular Trauma: A history of significant trauma or injury could alter local tissue responses and lead to growths.
- Previous Tumors: History of testicular or scrotal tumors may predispose one to new growths.
- Chronic Inflammation: Conditions like autoimmune disorders that affect the reproductive tract.
- Smoking: Known to increase general cancer risk; may have some influence on scrotal or testicular region.
- Obesity: Associated with hormonal fluctuations that might promote abnormal tissue growth.
- Poor Scrotal Support: Chronic irritation or micro-trauma from sports or inadequate protective gear.
- Uncontrolled Diabetes: Can impair blood flow and immune function, although it’s not a direct cause, it may contribute to abnormal growths.
- High-Fat Diet: May contribute to hormone imbalances and obesity, indirectly raising risk.
- Chronic Stress: Affects immune responses; prolonged stress might create an environment for tumor growth.
- Unprotected Sexual Activities: May increase the risk of infections that cause epididymal irritation over time.
- Use of Anabolic Steroids: Can cause hormonal shifts and possibly influence growth in the reproductive tract.
- Varicoceles: Abnormal veins in the scrotum can affect temperature regulation and blood flow, potentially impacting tissue health.
- Hydrocele: Fluid accumulation around the testicle that might affect local tissue environment.
- Idiopathic: In many cases, no specific cause is identified; the tumor arises for unknown reasons.
Common Symptoms
- Scrotal Lump: A palpable lump or swelling in the upper part of the testis area.
- Painless Swelling: Many epididymal tumors are painless at first.
- Mild Discomfort: A dull ache or sense of heaviness in the scrotum.
- Sharp Pain: Less common, but malignant tumors or larger growths can cause pain.
- Scrotal Redness: If inflammation accompanies the tumor.
- Swelling of the Testicle: General enlargement of the scrotal contents.
- Tenderness: Some tumors might become tender if they press on nearby structures.
- Changes in Scrotal Skin: Very rare, but lumps might cause skin changes.
- Abnormal Testicular Position: The epididymis might feel more prominent or be displaced.
- Fluid Accumulation: Sometimes a secondary hydrocele develops around the tumor.
- Fever or Chills: If there’s an infection or inflammation involved.
- Pain During Intercourse: Pressure in the scrotum might increase discomfort.
- Pain During Ejaculation: If the tumor blocks or irritates ducts.
- Back or Groin Pain: Larger tumors or metastases (in rare malignant cases) might cause referred pain.
- Feeling of “Pulling”: A sensation of being pulled inside the scrotum.
- Sensation of Fullness: Some men notice a fullness or bulge in the scrotum.
- Weight or Dragging Sensation: A feeling that the scrotum is heavier than usual.
- Enlarged Lymph Nodes: In malignant cases, nearby lymph nodes may become enlarged.

- General Malaise: Overall feeling of being unwell if the body is fighting inflammation or cancer.
Diagnostic Tests
Healthcare professionals use multiple steps to diagnose a suspected epididymal tumor:
- Physical Examination: Palpation of the scrotum to detect lumps, swelling, or pain.
- Medical History: Discussion of symptoms, onset, and family history.
- Scrotal Ultrasound: The most common imaging test to visualize lumps, fluid collection, or solid masses.
- Transillumination Test: Shining a light through the scrotum to check if the lump is solid or fluid-filled.
- Blood Tests:
- Complete Blood Count (CBC): Checks for signs of infection or anemia.
- Serum Tumor Markers: Such as alpha-fetoprotein (AFP), beta-hCG, and lactate dehydrogenase (LDH) if cancer is suspected.
- Urinalysis: Looks for signs of infection or blood in urine.
- MRI: May be used if ultrasound is inconclusive or more detailed imaging is needed.
- CT Scan: Often used to check for spread (metastasis) if malignancy is suspected.
- Fine Needle Aspiration (FNA): Uses a thin needle to collect cells from the lump.
- Biopsy: A more involved tissue sample procedure to determine if the tumor is benign or malignant.
- Hormone Level Tests: Check testosterone, estrogen, and other hormones.
- Physical Self-Exam Review: A demonstration on how to check lumps at home.
- Scrotal Thermography: Rarely used, measures heat differences in the scrotum.
