Over 95% of testicular cancer originates from the germ cells (the cells that produce sperm) of the testes; other types of testicular cancer arise from the other cells found in the testes. Although it represents less than one percent of cancers in men, testicular cancer is the leading cause of cancer in men aged 15 to 40. The cure rate is one of the highest of all cancers: the cure rate for all types and stages of testicular cancer combined is more than 90%; the most common treatment is the removal of the affected testicle. Testicular self-exams, as well as an annual doctor's exam are important to early diagnosis.

The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction . These organs are located on the outside of the body and within the pelvis.

The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant.

The corresponding system in females is the female reproductive system.
