The prostate is bounded laterally by which structure?

Understanding how the prostate sits in the pelvic space helps explain its borders. The prostate lies just below the bladder and in front of the rectum, embedded in the pelvic floor. Its lateral edges are defined by the muscles of the pelvic floor, specifically the levator ani, which form the side walls of this region. The rectum lies behind the gland, the bladder sits above and in front, and the urogenital diaphragm lies more inferiorly, contributing to the floor rather than the side walls. Because of this arrangement, the levator ani is the structure that truly forms the lateral boundary of the prostate.
