The Prostate Gland
The prostate gland is a firm, round body about the size of a chestnut, and it lies directly below the bladder. It is traversed by the urethra as well as the two ejaculatory ducts described earlier. The prostate constantly produces secretions. Some of these are passed off with the urine. Others make up the greater portion of the semen. In some older men, the prostate gland enlarges, causing pressure on the enclosed part of the urethra and thus making urination difficult. In these cases, surgery may become necessary.
