Prostate Peripheral Zone Dysfunction refers to issues or problems affecting the outer part (peripheral zone) of the prostate gland. The prostate is a small gland located just below the bladder in men, and it plays a critical role in reproductive health. Dysfunction in the peripheral zone of the prostate can lead to several medical issues, ranging from benign conditions to serious diseases like prostate cancer.
Pathophysiology (Structure, Blood, Nerve Supply)
The prostate is divided into different zones. The peripheral zone is the largest part and is located towards the outer part of the prostate. It’s crucial in producing and secreting prostate fluid, which forms part of semen.
- Structure: The peripheral zone surrounds the other zones and accounts for most prostate tissue. It contains a large number of glandular tissues responsible for producing prostate secretions.
- Blood Supply: The prostate is primarily supplied by the prostatic arteries, which branch off from the internal iliac arteries.
- Nerve Supply: The prostate receives nerve fibers from the pelvic plexus, which controls functions like ejaculation and urination.
When there is dysfunction in this zone, it can affect the secretion process and lead to various health problems.
Types of Prostate Peripheral Zone Dysfunction
- Benign Prostatic Hyperplasia (BPH): Enlargement of the prostate that is common with age.
- Prostatitis: Inflammation of the prostate due to infection or other causes.
- Prostate Cancer: Malignant growth in the prostate, often affecting the peripheral zone.
- Prostate Atrophy: Shrinking or wasting of prostate tissue.
- Prostate Stones: Hardened deposits that form inside the prostate.
- Prostate Calcification: The buildup of calcium in prostate tissue.
- Fibrosis of the Peripheral Zone: Scarring of prostate tissue leading to dysfunction.
