Testicular self-examination is an examination of the testicles. The testicles (also called the testes) are the male reproductive organs that produce sperm and the hormone testosterone. They are located in the scrotum under the penis.
Perform this test during or after a shower. This way, the scrotal skin is warm and relaxed. It's best to do the test while standing.
A testicular self-exam is done to check for testicular cancer. Normal testicles contain blood vessels and other structures that can make the exam confusing. Performing a self-exam monthly allows you to become familiar with your normal anatomy. Then if you notice any changes from the previous exam, you'll know to contact your doctor.
You should perform a testicular self-exam every month if you have or have had any of the following risk factors:
Each testicle should feel firm, but not rock hard. One testicle may or may not be lower or slightly larger than the other.
Always ask your doctor if you have any doubts or questions.
If you find a small hard lump (like a pea), have an enlarged testicle, or notice any other concerning differences from your last self-exam, see your doctor as soon as you can.
Consult your doctor if:
Sudden, severe (acute) pain in the scrotum or testicle is an emergency. If you experience such pain, seek immediate medical attention.
A lump on the testicle is often the first sign of testicular cancer. Therefore, if you find a lump, see a doctor immediately. Keep in mind that some cases of testicular cancer do not show symptoms until they reach an advanced stage.
