The prostate gland weighs approximately 20 g in the normal adult. It encircles the bladder neck and urethra, and comprises five lobes: a posterior, middle, and anterior lobe and two lateral lobes. In the course of development the five become fused into three distinct lobes—two major lateral lobes and one fused small median and posterior lobe.
