What Is The Prostate Gland?

The first step toward understanding how the prostate affects your health is to learn what the prostate is and how it functions.

The prostate gland makes up an important component of the human male reproductive system. So let’s take a deeper look at this gland with some facts you’re likely not familiar with.

A normal prostate gland is approximately 1½ inches long and weighs about an ounce.

The prostate gland is about the size of a walnut and surrounds the neck of a man’s bladder and urethra.  It is made up of three lobes: a center lobe with one lobe on each side.

The prostate gland is dependent on testosterone for it to function.

Prostate gland secretions comprise a large portion of seminal fluid and proper function of the gland is crucial to sexual capability in men.

Semen is produced by both the prostate gland and the seminal vesicles, a pair of glands attached to the prostate.

It completely surrounds the urethra, which is the tube that takes urine and sexual fluids through the penis and out of the body.

The prostate gland is also responsible for sealing off the entry from the bladder into the urethra with the help of a muscle called a sphincter. This prevents the flow of urine during sexual intercourse.

The prostate also filters and removes toxins for protection of the sperm, which enhances the chance of impregnation and ensures that men seed with the optimum quality of sperm.
