What are the testicles?
The testicles produce several male hormones, including testosterone and sperm. The hormones control the development of the reproductive organs, as well as other male characteristics - body and facial hair, low voice, and wide shoulders.
What is testicular cancer?
Cancer that develops in a testicle is called testicular cancer.
When testicular cancer spreads, the cancer cells are carried by blood or by lymph, an almost colorless fluid produced by tissues all over the body. The fluid passes through lymph nodes, which filter out bacteria and other abnormal substances such as cancer cells
The testicles are the male sex glands and are part of the male reproductive system. Testicles are also called testes or gonads. They are located behind the penis in a pouch of skin called the scrotum.
