Although men in their twenties can suffer from BPH, it usually surfaces later in life. by age 70, more than 40% of men will have enlargement of the prostate that can be felt during a physical examination.
The prostate grows in two different ways. In one type of growth, cells multiply around the urethra and squeeze it, much like you can squeeze a straw. The second type of growth is middle-lobe prostate growth in which cells grow into the urethra and the bladder outlet area.If the prostate enlarges outward, a man probably won't know he has BPH (unless it grows upward and pushes into the bladder). But if it swells inward, squeezing the urethra which passes through the center of the gland, he will know there's a problem.
