Doctor's Notes on Testicle Infection (Epididymitis)

A testicular self-examination (TSE) is used to help detect testicular cancer, the most common solid tumor found in males age 20-34 years. The best time to examine testicles is during or after a shower or bath because the warm water allows the scrotum to relax and the testicles to the dropdown. It is recommended that young men examine themselves once a month. A doctor can instruct you on the correct way to do a testicular self-examination. If you find a lump, contact a doctor for an evaluation.

Symptoms of testicular cancer include

  • a small, painless lump in a testicle,
  • a feeling of heaviness in the testicle,
  • enlarging male breasts or breast tenderness,
  • testicle enlargement,
  • a new collection of fluid or blood in the scrotum around the testicle, or
  • testicular pain.

What is the Treatment for a Testicular Lump Found on Testicular Self-Examination?

If a testicular lump or mass is found on testicular self-examination, see your doctor. You will most likely be sent to a urologist for an evaluation. An ultrasound may be ordered to better indicate the type of lump. Most lumps are benign and do not need any specific treatment. 

Treatment for a testicular lump depends on the type of lump. 

  • Hydroceles are fluid-filled cysts on the testicle 
    • Large hydroceles may need to be drained or surgically removed, but most times do not require treatment
  • Epididymitis is an infection of the sperm storage area adjacent to the testicle and when enlarged feels like a lump
  • Treatment for testicular cancer usually includes surgery to remove the tumor, often followed by chemotherapy
