Testicular Lump Symptoms

A testicular lump is an abnormal mass that forms in the testicles. The testicles (also known as testes) are the round, egg shaped male reproductive organs that hang behind the penis. The testicles are encased by a sac of skin called the scrotum, and the main function of this system is the production of sperm and testosterone, a hormone important for male sexual and reproductive development.

See this image for a visual representation of the testicle and scrotum, and its spatial relationship to the penis here.

Testicular lumps can often be painless and without symptoms.

But sometimes, in addition to the palpable mass, you may experience:

Lumps of the testes are always abnormal and should always be followed-up by a doctor. Even if you do not experience any testicular lump symptoms, it is still important to make an appointment with your doctor because sometimes testicular lumps can signal serious, underlying medical problems.

Testicular Lump Causes Overview

The causes of testicular lumps can range from benign to malignant conditions, thus medical follow-up is always necessary in order to find the exact cause. The scrotum not only contains the testicles but also the various arteries, vessels and nerves that supply the testicles. The scrotum is also attached to the abdomen by a structure called the inguinal canal. The inguinal canal contains the spermatic cord, a structure that contains a bundle of nerves, ducts, and blood vessels. Complications in any of these components can cause testicular lumps.

Inflammatory causes:

  • Infection: Bacteria can easily infect the testicles (orchitis) and other structures encased in the scrotum. Infections often cause pain and generalized swelling. The swelling can often manifest as a testicular lump. This lump can be tender but not hard to the touch.
  • Fluid build-up: When blood, sperm fluid or generalized fluid accumulates in the scrotum, the scrotum enlarges and swelling results. A lump filled with blood is a hematocele; a lump filled with sperm fluid is a spermatocele; and a lump filled with generalized fluid is a hydrocele. These types of lumps are often painless and can make the affected scrotum feel heavier than the other. Veins to the scrotum can also become enlarged, especially after puberty when blood flow to the testicles increases. This type of lump (varicocele) often has a "bag of worms" appearance – see this photo for a visual representation.

Structural causes:

  • Torsion: Torsion occurs when the testicle rotates around the spermatic cord. This condition can result in a lump because the twisting can block blood flow to the scrotum. This blockage will result in buildup and swelling that can appear as a testicular lump. Torsion is extremely painful and extremely dangerous. If you experience sudden , severe pain in the testicle area, call 911 and go to the emergency room immediately.
  • Hernia: Hernias occur when fatty or intestinal tissues protrude through a weakness in the abdominal wall close to or through the inguinal canal. Hernias that protrude through the inguinal canal are called inguinal hernias. Because the inguinal canal is in direct communication with the scrotum, these hernias can appear as protruding bulges in that area. This bulge will feel hard and solid. Sometimes the bulge can increase in size when a person stands up or coughs. At other times, this lump can be pushed back up into the abdomen.

Systemic causes

  • Lumps in the testicle can signal malignant and non-malignant types of cancer. These lumps often feel hard, solid and fixed in place. Testicular cancers are rare but easily treatable. A physician can diagnose if your lump is cancer; thus, it is very important to make an appointment with your doctor as soon as you notice any testicular lump symptoms.

A.I. Health Assistant Causes for Testicular Lump

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced testicular lump. This list does not constitute medical advice.

  1. 1.Testicular Cancer

    Testicular cancer is a condition where cells inside the testicle begin to grow out of control, forming a lump (called a tumor). These cells may spread (metastasize) to other parts of the body.

    Outlook is better than most cancers, and your ability to have sex or have children will not be affected.

    Rarity:
    Rare
    Top Symptoms:
    testicular lump, spontaneous testicle pain, hard testicle lump, swelling of one ear
    Urgency:
    Primary care doctor
  2. 2.Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling.

    With prompt treatment, it is unlikely there will be any permanent damage. It is important to get to the hospital within 6 hours of the start of pain to make sure the testicle can be saved.

    Rarity:
    Rare
    Top Symptoms:
    testicle pain, nausea, pain in one testicle, vomiting, testicular swelling
    Symptoms that always occur with testicular torsion:
    testicle pain
    Urgency:
    Hospital emergency room
  3. 3.Genital Warts

    Genital warts are one of the most common sexually transmitted infections. It is caused by infection by Human Papilloma Virus (HPV). While it cannot be cured, treatment may help.

    Infection with HPV cannot be cured, but the warts themselves can be removed surgically or sometimes resolve themselves in a matter of weeks.

    Rarity:
    Uncommon
    Top Symptoms:
    small groin lump, skin-colored groin bump, marble sized groin lump, painless groin lump, scaly groin bump
    Symptoms that always occur with genital warts:
    scaly groin bump
    Urgency:
    Primary care doctor
  4. 4.Intermittent Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling. In the case of intermittent testicular torsion, the testicle de-rotates itself and symptoms resolve.

    Symptoms resolve within a few days

    Rarity:
    Rare
    Top Symptoms:
    nausea, testicle pain that comes and goes, vomiting, pain in one testicle, testicular swelling
    Symptoms that always occur with intermittent testicular torsion:
    testicle pain that comes and goes
    Urgency:
    Primary care doctor

  5. 5.Non - Hodgkin Lymphoma

    Non-Hodgkin lymphoma is a cancer of the lymphatic system, which is part of the immune system. Cells in the lymph nodes or bone marrow grow abnormally and may spread beyond the lymphatic system.

    Curable but survival rates are variable depending on the subtype.

    Rarity:
    Ultra rare
    Top Symptoms:
    fatigue, loss of appetite, abdominal pain (stomach ache), fever, shortness of breath
    Symptoms that never occur with non-hodgkin lymphoma:
    neck lump that comes and goes, shrinking neck bump, armpit lump that comes and goes, shrinking armpit lump, groin lump that comes and goes, shrinking groin lump
    Urgency:
    Primary care doctor
  6. 6.Non - Serious Testicle Injury

    Being struck in the testicles is very common, and despite the intense pain that follows, rarely requires professional medical care.

    Your testicle pain should resolve in 5-15 minutes. If it lasts for an hour or more, consider a visit to an urgent care center.

    Rarity:
    Rare
    Top Symptoms:
    testicle pain from an injury, testicle injury
    Symptoms that always occur with non-serious testicle injury:
    testicle injury
    Urgency:
    Self-treatment
  7. 7.Orchitis

    Orchitis occurs when one or both testicles are inflamed. This is often caused by sexually transmitted infections like gonorrhea or chlamydia. More rarely, orchitis is caused by a virus.

    Most people begin to feel better in a few days although it may take up to a month for the tenderness to fully disappear.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous testicle pain, fever, tender testicular swelling, muscle aches, new headache
    Urgency:
    Primary care doctor
  8. 8.Groin Hernia

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. With age, the supportive tissues that keep organs within the abdomen become weaker, and the risk for a hernia increases. Groin hernias, called inguinal hernias, are the most common type. They often result due to muscle straining, such as during heavy lifting.

    Groin hernias are not a life-threatening condition. Approximately one third of patients report chronic groin pain 1 year or longer after a hernia repair, but it is likely to dissipate over time. A hernia may recur, although the causes of this are highly variable, and depend on the degree of abdominal wall weakness and the technique of repair.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in the lower right abdomen, pain in the lower left abdomen, groin pain, testicle pain, groin lump
    Urgency:
    Primary care doctor

Testicular Lump Treatments and Relief

Treatment for your testicular lump will be dependent on the cause.

But there are general testicular lump treatments and medications your doctor may suggest including:

  • Pain medication: Pain and lumps caused by swelling often go hand-in-hand. Your doctor may prescribe over the counter pain medications to combat these testicular lump symptoms.
  • Antibiotics: If your symptoms are due to infectious causes. Your doctor will prescribe antibiotics to fight the infection and provide you with relief.
  • Surgery: Testicular torsion requires immediate surgery in order to untwist the spermatic cord and restore blood flow to the testes. Hernias and cancers are also treated using surgery.

Questions Your Doctor May Ask About Testicular Lump

  • Q.Does the bump feel like an area of thickened skin?
  • Q.Do you notice anything going on with your testicles or scrotum?
  • Q.Please say more about the bump on your testicle. Do you feel pain when you touch the bump?
  • Q.Lie down on your right side and have someone press deeply under your left rib cage (on the border between the back and stomach). Do you feel a large lump right below your lowest left rib that isn't normally there?
