sudden testicular

Overview

Sudden pain in one or both testicles (the male sex organs that make sperm). It can happen quickly and may come with swelling, tenderness, or a change in how the testicle feels. It is a symptom, not a disease itself.

It is not one of the most common symptoms men have, but it is a reason some men go to the emergency room. Knowing the warning signs can help you act quickly.

It can affect boys and men of any age. Testicular torsion is most common in teenagers and young men, while infections are more common in sexually active men, but anyone can be affected.

Symptoms

Common symptoms

• Sudden, sharp pain in one or both testicles
• Swelling or redness of the scrotum (the sac that holds the testicles)
• Tenderness when the testicle is touched
• Nausea or vomiting
• Pain in the lower belly or groin
• A testicle that hangs higher than usual

Symptoms in children

• A baby who cries suddenly and is hard to comfort
• A boy who says his testicle or belly hurts
• Swelling or redness in the scrotum
• Vomiting
• The scrotum looks larger on one side

Symptoms in older adults

• Pain that starts slowly or suddenly
• A heavy or dragging feeling in the scrotum
• Pain with urination or a need to urinate often
• Fever or chills
• A lump or hard area in the testicle

Causes

Main causes

• Testicular torsion – the spermatic cord twists, cutting off blood flow. This is a medical emergency.
• Epididymitis – swelling of the tube that carries sperm, often from a bacterial infection.
• Trauma – a direct hit or injury to the testicles.
• Inguinal hernia – a part of the intestine pushes into the scrotum.
• Testicular cancer – usually causes a painless lump, but can also cause pain or swelling.
• A kidney stone – a stone in the urinary tract can cause pain that travels to the testicle.

Risk factors

• Being a teenager or young adult (for torsion)
• A previous torsion that went away on its own (this can mean a higher risk of it returning)
• Physical activity or sports that involve the groin
• Sexually transmitted infections (for epididymitis)
• A family history of testicular problems (rare)

When to see a doctor

See a doctor urgently if:

• If you have sudden, severe testicle pain, go to an emergency room right away. Do not wait.
• If you have pain with nausea, vomiting, or a swollen, red scrotum, call your local emergency number now.
• If you had an injury to the testicle and the pain is getting worse, get emergency care.

Book a routine appointment if:

• If you feel a painless lump or a change in the size of a testicle, make a doctor's appointment within a few days.
• If you have mild pain that comes and goes, or pain with urination, see a doctor soon.
• If you have a fever or discharge, see a doctor.

Diagnosis

Your doctor will ask about your symptoms and check the area by physical exam. They will look for swelling, tenderness, and how the testicle sits. This is often the fastest way to guide next steps.

Tests that may be done

• Urine test – to check for a urinary tract infection or sexually transmitted infection.
• Blood tests – to look for signs of infection or other problems.
• Ultrasound – a painless test that uses sound waves to see blood flow to the testicle. This is the main test for torsion.
• Emergency surgery – if ultrasound is not possible or the doctor is still worried about torsion, surgery may be done to check the testicle directly.

What to expect at your appointment

If you go to an emergency room, doctors will act quickly. If torsion is found, you will have surgery right away. If the cause is an infection, you may get antibiotics and advice on relieving pain. In many cases, you will feel better within a few days.

Treatment

Treatment depends on the cause. Testicular torsion needs emergency surgery to untwist the cord and restore blood flow. An infection is treated with antibiotics and rest. An injury may only need supportive care. If cancer is found, treatment will be planned by specialists and often involves surgery to remove the affected testicle, and sometimes additional therapies.

Self-care at home

• Rest and avoid strenuous activity until a doctor says it is safe.
• Wear supportive underwear or a towel to support the scrotum.
• Use a cold pack wrapped in a cloth on the area for short periods to help with swelling.
• Ask your doctor or pharmacist what pain relief, if any, is right for you.

Medical treatments

Your doctor may prescribe antibiotics if an infection is the cause. They may recommend an anti-inflammatory medicine to reduce swelling. For testicular torsion, surgery is the only way to fix it. If the testicle is damaged beyond repair, it may be removed to prevent further problems. For cancer, your care team will explain the best options, which may include surgery, radiation, or chemotherapy.

When is surgery considered?

Surgery is needed for testicular torsion, and it works best within 6 hours of the pain starting. Surgery may also be needed for a severe hernia, some injuries, or to remove a testicle affected by cancer.

Living with this condition

After treatment, you can usually return to your normal routine, but you may need to avoid sports or heavy lifting for a few weeks. Follow your doctor's instructions about rest, wound care, and when it is safe to be active again.

Lifestyle tips

• Wear a protective cup during contact sports.
• Wear supportive underwear during exercise.
• Do a monthly self-check so you notice changes early.

Diet and exercise

Eat a healthy, balanced diet to help your body heal. Once your doctor says it is safe, light exercise like walking can be good. Avoid intense exercise until fully recovered.

Mental health and emotional wellbeing

Testicle pain can cause fear and anxiety. You may worry about your health, your fertility, or your body. These feelings are normal. It can help to talk to someone you trust, or to a counselor. Remember that even serious causes can often be treated successfully.

Prevention

Not all causes can be prevented, but you can lower your risk of injury by wearing protective gear during sports. Regular self-checks help you notice lumps or changes early, which can improve outcomes if cancer is found.

Vaccines

There is no vaccine for testicular pain itself, but some infections that can affect the testicles, like mumps, can be prevented with routine childhood vaccines. Ask your doctor if your vaccinations are up to date.

Screening programmes

There is no routine screening test for testicular cancer in men without symptoms. The best practice is to be familiar with how your testicles normally feel and see a doctor if you notice any lump, swelling, or change.

Complications

If left untreated

• Loss of the testicle if torsion is not treated quickly
• Long-term pain or reduced fertility
• Spread of infection to other parts of the body
• If cancer is the cause, delay in diagnosis may reduce treatment options

Long-term outlook

With prompt care, most causes of sudden testicular pain can be treated successfully. Even testicular cancer has a high cure rate, especially when caught early. You will likely return to your daily life and remain healthy. Your doctor will help you through each step.
