It surrounds the neck of the bladder and the urethra, a small tubular structure that drains urine from the bladder to the penis. The prostate gland is a common site of disorders in the male genitourinary system. As men age, their prostate gland often enlarges. This condition is referred to as Benign Prostate Hypertrophy or BPH.
