Overview

The testicles are two glands inside the scrotum (a sac of loose skin below the penis). The testicles make sperm and the hormone testosterone.

Testicular cancer is the most common cancer in men 15-34 years of age. The two main types of testicular tumors are seminoma and nonseminoma. Nonseminomas tend to grow and spread more quickly than seminomas.

The most common sign of testicular cancer is a lump or swelling in the testicle. Most testicular cancers can be cured, even if they are diagnosed at an advanced stage.

Treatment for testicular cancer can cause infertility by decreasing the amount of sperm made by the body. Men who want to have children may want to use sperm banking to store sperm before they begin treatment.
