Benign prostatic hyperplasia (BPH): The enlargement of the prostate gland is benign prostatic hyperplasia (BPH). It is a non-cancerous growth of the prostate gland caused due to overproduction of dihydrotestosterone hormone in men. After age 50, most men develop an enlarged prostate gland putting pressure on the urinary bladder. It leads to restricted or obstructed urine flow, an urge to urinate frequently (especially at night), and a feeling of not emptying the urinary bladder.
