The Prostate

The prostate is a small gland about the size and shape of a walnut. It is located under the bladder, in front of the rectum, and surrounds part of the urethra (the tube that empties urine from the bladder). If the prostate grows too large, the flow of urine can be slowed or stopped. The prostate makes, stores, and secretes fluid that forms part of the semen in which sperm are transported.
