Contents and zones of the prostate gland; Peripheral zone, central zone, Transitional zone, Anterior

prostate gland is a vital male reproductive organ located below the bladder and surrounding the urethra. It produces seminal fluid, which nourishes and transports sperm. Anatomically, the prostate is divided into distinct zones based on histological and functional characteristics: Zones of the Prostate Gland: Peripheral Zone (PZ): The largest zone, making up about 70% of the prostate in young men. Located at the posterior and lateral aspects of the gland. Most prostate cancers originate in this zone. Readily accessible during a digital rectal exam (DRE). Central Zone (CZ): Constitutes about 25% of the prostate. Surrounds the ejaculatory ducts. Relatively resistant to pathological changes like cancer. Transitional Zone (TZ): Smallest zone in young men but enlarges with age, contributing to benign prostatic hyperplasia (BPH). Surrounds the proximal urethra. Anterior Fibromuscular Zone (AFMZ): Located anteriorly, it primarily consists of fibrous and muscular tissue. Does not typically contain glandular tissue, making it less involved in most prostatic diseases #Prostate
