Anatomy of the Prostate Gland

Facts about the prostate gland:

The prostate gland is about the size of a walnut and surrounds the neck of a man's bladder and urethra - the tube that carries urine from the bladder. It is partly muscular and partly glandular, with ducts opening into the prostatic portion of the urethra. It is made up of three lobes: a center lobe with one lobe on each side.

Function of the prostate gland:

As part of the male reproductive system, the prostate gland's primary function is to secrete a slightly alkaline fluid that forms part of the seminal fluid, a fluid that carries sperm. During male climax (orgasm), the muscular glands of the prostate help to propel the prostate fluid, in addition to sperm that was produced in the testicles, into the urethra. The semen then leaves the body out through the tip of the penis during ejaculation.
