The prostate gland is an accessory, unpaired sex gland of males that surrounds the urethra as it leaves the bladder. The prostate is an aggregation of 30 to 50 branched tubuloalveolar glands that secrete a milky fluid rich in citric acid and acid phosphatase. Grossly, the prostate gland has five lobes and is about one and a half inches in diameter. It is surrounded by a fibromuscular capsule. | The prostate gland is an accessory, unpaired sex gland of males that surrounds the urethra as it leaves the bladder.

For most of its length the penile urethra is lined by non-secreting columnar epithelium into which small mucus glands embedded in the corpus spongiosum drain. Within the glans penis, however, the urethra dilates (navicular fossa) and becomes lined by non-keratinizing stratified squamous epithelium identical to that covering the glans. | For most of its length the penile urethra is lined by non-secreting columnar epithelium into which small mucus glands embedded in the corpus spongiosum drain.
