Enlarged Prostate (BPH)

What is the prostate?

The prostate is a gland in the male reproductive system. It lies just below the bladder. It makes fluid that is part of semen.

What is an enlarged prostate (BPH)?

An enlarged prostate is when your prostate gland becomes larger than normal. It's also called benign prostatic hyperplasia or BPH for short. Benign means not cancer. And hyperplasia means too much cell growth. BPH isn't cancer and it doesn't increase your risk of getting prostate cancer.

Usually, the prostate gland continues to grow during adult life. That's why BPH is the most common prostate condition in people over age 50. As the prostate gets bigger, it may press against the bladder and pinch the urethra. This can slow or block the flow of urine out of your bladder.

Over time, the bladder muscle may become weak from trying to pass urine through a narrow urethra. When this happens, your bladder may not empty completely when you urinate. A narrowed urethra and weak bladder cause many of the urinary problems you may have with BPH.

Researchers aren't sure why the prostate keeps growing. Some researchers think changes in hormones with aging may cause the prostate to get bigger.
