Anatomy of the Prostate Gland

Facts about the prostate gland:

Prostate anatomy

The prostate is a sex gland in men. It is about the size of a walnut, and surrounds the neck of the 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.

The prostate gland secretes a slightly alkaline fluid that forms part of the seminal fluid, a fluid that carries sperm.
