The rate among Hispanic men lies between those of blacks and whites. Testicular cancer is 3 to 17 times more likely to develop in these men. Testicles are male reproductive organs. They produce and store sperm. They also produce testosterone, a hormone that causes such male traits as facial hair and lower voice pitch.
Testicles are smooth, oval-shaped, and somewhat firm to the touch.
They are below the penis in a sac of skin called the scrotum. The testicles normally descend into the scrotum before birth. Parents should have their infant sons examined by a doctor to be sure that the testicles have properly descended. If they have not, this can be easily corrected with surgery. Fifteen years ago, testicular cancer was often fatal because it spread quickly to vital organs such as the lungs.
