About 165 Victorian males are diagnosed with this cancer each year. In most cases, testicular cancer is curable. The testicles (testes) are two small, oval-shaped organs located behind the penis in a skin sack called the scrotum. They are part of the male reproductive system. Sperm and sex hormones are made by the testicles.
Testicles are parts that are found on the bodies of male creatures. Male mammals, including men, have two testicles, supported in a sac of skin below the penis called the scrotum. Along with the penis, testicles are called reproductory organs or sex organs. Only males have testicles; females have ovaries. Testicles are a type of organ called glands. Like other glands, testicles make chemical substances, called hormones that keep the body working.
