How to Do a Testicular Self-Exam (Slideshow)

Testicular self-exams (TSE) can help you check for things like cancer. Although testicular cancer is rare in teenage guys, overall it is the most common cancer in males between the ages of 15 and 35.

It's important to try to do a TSE every month so you can become familiar with the normal size and shape of your testicles, making it easier to tell if something feels different in the future.
