How is the zonal anatomy of prostate?

3 Main Zones (central, transition and peripheral zone) Transition (glandular portion of prostate, in direct contact w/urethra, BPH born in this area periurethral, rarely prostate cancer) Central (Non glandular portion surrounds transition zone, dense stroma and transition zone, rarely cause of cancer but important role in BPH develops at age 40 in man) Peripheral Zone (Posterior prostate, in contact with rectum, 80% of gland volume and its the area of prostate cancer) + we can add anterior zone closest to abdomen, non-glandular fibromusclar tissue.
