What is the prostate gland?

Mark S. Litwin, MD
The prostate gland is one of the male reproductive organs, and is located deep in the male pelvis. (Women do not have a prostate gland.) The prostate gland's primary function is to play a role in reproduction and in sexual function.
The prostate is one of the male sex glands and is located just below the bladder (the organ that collects and empties urine) and in front of the rectum (the lower part of the intestine). The prostate is about the size of a walnut. It surrounds part of the urethra, the tube that carries urine from the bladder to the outside of the body. The prostate makes fluid that becomes part of the semen, the white fluid that contains sperm.

The prostate gland is a male sex gland. It needs male hormones, primarily testosterone, to function. It is about the size of a walnut and is located in front of the rectum, behind the base of the penis and directly under the bladder. It is found only in men, and its function is to produce a thick fluid that is part of semen, that helps protect and nourish sperm cells and enables sperm to be released during ejaculation. The prostate surrounds the upper part of the urethra, the tube that empties urine from the bladder. Nerves involved in causing an erection of the penis are located adjacent to the prostate. This makes men who undergo prostate treatment susceptible to erectile problems, or impotence, as a result of damage to these nerves.

The prostate is a walnut-sized gland that sits below the bladder and in front of the rectum and helps produce the fluid that creates semen. Prostate cancer, which affects about 1 in 6 men, is one of the most common male cancers. It’s critical that men get checked annually starting around 40 years old and definitely by the time they reach 50.
