There are two types of testicular exams: one done by a health care provider and a testicular self-exam which a boy or man can do on himself, or have his partner do for him. During a testicular exam, a health care provider visually and manually checks the scrotum—the loose bag of skin which holds the testes—and penis for lumps or growths on the skin. The purpose of a testicular exam is to have a male familiarize himself with his body, so if there are lumps, bumps or warts, he can have them checked out by his health care provider. Some medical professionals recommend that guys perform monthly testicular self-exams. Early detection is the best way to improve the chances of survival if the abnormality is found to be cancerous.
