The Male Reproductive System

Abstract

This organ surrounds the urethra as it leaves the bladder and this part is called the prostatic urethra. The prostate has been described as being the shape and size of a chestnut. Most of it lies behind the urethra only a small rim of tissue lying in front. Above is the neck of the bladder, below the tip rests on the external sphincter of the bladder. On either side are the fibres of muscles which run from the pubis to the rectum, in front lies the symphysis pubis and behind the rectum. The prostate can be palpated on rectal examination. A median groove divides it into right and left lobes. A further median lobe is marked off by the two ejaculatory ducts which open into the prostatic urethra.
