The Prostate Gland – The Function And Facts About 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 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.
One of the most important prostate functions is the secretion of alkaline fluid that adds to the bulk of the semen. Semen is a mixture of fluid from three accessory male sex glands i.e. seminal vesicles, bulbourethral and prostate; semen is discharged during ejaculation in men and contains sperms. 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.
Facts about the prostate gland
- Prostate gland secretions comprise a large portion of seminal fluid and proper function of the gland is crucial to sexual capability in men.
- The prostate gland contains five areas, or zones. The peripheral zone is the largest segment, containing about 75% of the glands in the prostate. Most prostate cancer occurs in the peripheral zone and is the site where most needle biopsies are taken.
- The prostate gland is dependent on testosterone for it to function.
- 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 contains muscles which help in expelling the semen out of the penis during sexual intercourse.
- Semen is produced by both the prostate gland and the seminal vesicles, a pair of glands attached to the prostate.
- 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.
- A normal prostate gland is approximately 1½ inches long and weighs about an ounce.
- 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.
