Testicular self-exam is an examination of the testicles that you do on yourself.
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.
You can do this test during or after a shower. This way, the scrotal skin is warm and relaxed. It is best to do the test while standing.
A testicular self-exam may be done to check for testicular cancer.
Testicles have blood vessels and other structures that can make the exam confusing. If you notice any lumps or changes in a testicle, contact your health care provider right away.
Doctors may recommend that you do a testicular self-exam every month if you have any of the following risk factors:
Some, but not all expert organizations, recommend self-exam if you are a teenager or young adult (to about 35 years old). It is not clear that performing this exam when you have no symptoms would decrease the risk of dying from testicular cancer.
Each testicle should feel firm, but not rock hard. One testicle may be lower or slightly larger than the other.
Talk to your health care provider if you have questions.
If you find a small, hard lump (like a pea), have an enlarged testicle, or notice any other differences that do not seem normal, see your health care provider right away.
Call your health care provider if:
Sudden, severe (acute) pain in the scrotum or testicle that lasts for more than a few minutes is an emergency. If you have this type of pain, seek medical attention right away.
A lump in the testicle is often the first sign of testicular cancer. If you find a lump, see a health care provider right away. Most testicular cancers are very treatable. Keep in mind that some cases of testicular cancer do not show symptoms until they reach an advanced stage.
