The prostate is part of the male reproductive system. It is a walnut-sized and shaped gland located below the bladder and in front of the rectum and surrounds the urethra (a tube-like structure that carries urine form the bladder out through the penis).
Reproductive System and the Prostate
The main function of the prostate is to produce ejaculatory fluid. It secretes seminal fluid, a milky substance that combines with sperm to form semen. The fluids help the movement and nourish the sperm by keeping it liquid and preventing it from becoming too sticky. During sexual climax, muscles in the prostate propel the semen through the urethra and out through the penis.
Urinary System and the Prostate
Although the prostate gland is not a major component of the urinary system, it can cause urinary discomfort, especially when it becomes enlarged. Urine is produced by the kidneys, which continuously filter the blood and remove impurities, toxins, waste products, unneeded nutrients and extra water. Since the blood is being filtered and purified all the time, urine is also produced around the clock. Each kidney is connected to the bladder by a narrow muscular pipe called the urether. Once formed, the urine flows from the kidneys to the bladder. This process continues until the bladder becomes full, at which time it sends a message to the brain, which in turn informs you that it is time to go to the bathroom to urinate.
Men are more likely to get urinary tract infections when they have an enlarged prostate gland.
