The prostate is a gland that produces fluid (semen) in which sperm swim.
The prostate cannot be seen or felt outside of the body becasue it lies between the penis and the bladder. A doctor can feel the prostate when doing a Digital Rectal Examination (DRE)
It is normally the size of a walnut and looks similar to a ring donut. The shape allows a tube to run through it. This tube (The Uretha) allows urine to pass from the bladder throuhg the penis to outside of the body.
