The prostate is a small gland approximately the shape and size of a walnut. The prostate is part of the male reproductive tract. It creates fluid that combines with sperm to generate semen. This prostate gland consists of two lobes that are enclosed by an outer layer of tissue. The prostate sits right in front of the rectum and just below the bladder, where urine is stored. The prostate also surrounds the urethra, the canal through which urine passes out of the human body.

Causes
Currently the enlargement of the prostate gland isn’t something that requires any specific occasion, or to say it does not demand any cause. When the testosterone levels rise during puberty the gland that was once tiny during birth begins to grow quickly. It starts doubling in size from the age of 20.
Development slows down to the next two decades and the prostate usually does not cause problems for several years. Less than 10 percent of 30-year-old men have an enlarged prostate. When a man reaches his 40s, the prostate goes through another growth spurt. Half all men have an enlarged prostate by the time they reach age 60, and by age 85, 90% of men have an enlarged prostate.
During puberty, the prostate expands evenly. The augmentation that occurs in the second half of daily life, however, is concentrated in the part of the gland next to the urethra. Since the gland gets bigger, it interferes with the flow of urine from the bladder. That makes the bladder function more difficult to empty pee. Over time, the problem worsens, and eventually not all of the urine can be emptied. The bladder wall can also become thickened, which can result in muscle spasms.
