The prostate gland controls the flow of urine and adds fluid to semen. Prostate enlargement, or benign prostatic hyperplasia (BPH), and other problems like prostatitis become more common as men age. Prostate symptoms may include a burning sensation when urinating, inability to urinate or frequent urination. Prostatitis and enlarged prostate treatment may include medication, TURP, prostate surgery and natural remedies like saw palmetto.
