Inferior. Except for a variable layer of endopelvic fascia, the neck of the bladder rests directly on the pelvic floor muscles (e.g., levator ani) in females, whereas in males the prostate gland is interposed between them. In the male, the internal urethral orifice lies about 1 or 2 cm superior to, and 2 cm posterior to, the subpubic angle. In the female, the position of the urethral orifice is slightly more inferior. In the newborn, the bladder is more abdominal than pelvic in position, and the urethral orifice may be situated as far superiorly as the pubic crest.

LIGAMENTOUS ATTACHMENTS

The inferior, subperitoneal aspect of the bladder is connected to the pubis by two ligaments originating in the prostatic fascia in males and vesical fascia in females.
