By Mayo Clinic staffThe prostate gland is the male organ that produces semen, the milky-colored fluid that nourishes and transports sperm during ejaculation. It sits beneath your bladder and surrounds your urethra — the tube that drains urine from your bladder. When it becomes enlarged, the prostate can put pressure on your urethra and cause difficulty urinating.
Most men have a period of prostate growth in their mid- to late 40s. At this time, cells in the central portion reproduce more rapidly, resulting in prostate gland enlargement. As tissues in the area enlarge, they often compress the urethra and partially block urine flow. Benign prostatic hyperplasia (BPH) is the medical term for prostate gland enlargement.
Treatment of prostate gland enlargement depends on your signs and symptoms and may include medications, surgery or nonsurgical therapies. Prostate gland enlargement is not related to the development of prostate cancer.
