Why does BPH (benign prostatic hyperplasia) occur?

Why does BPH occur?
It is important to note that there are several different reasons why the prostate can enlarge including bacterial infection resulting in bacterial prostatitis. Make sure that you understand and have successfully identified the reasons behind your prostate condition before you attempt any treatment.
The prostate is a small gland that encompasses the narrow part of the urinary bladder and urethra in men. Its major function is to manufacture and secrete seminal fluid which forms a substantial part of ejaculate. Unlike the rest of the body, the prostate undergoes two separate growth spurts at different times in the male’s life. In early puberty, the prostate doubles in size and then once again at around the age of 25, it starts to grow again, continually growing at a slower rate as the man ages.
When the prostate becomes enlarged, the prostate acts as a clamp on the neck of the urinary bladder which then creates issues with urination such as frequency, strength and duration.
BPH can raise PSA (prostate-specific antigen) levels two to three times higher than the normal level (0-4). An increased PSA level does not indicate cancer, but the higher the PSA level, the higher the chance of having cancer.
