Pelvic outlet

Pelvic outlet is the lower opening of the pelvis. The pelvic outlet is larger in females than in males, which allows for childbirth. The size and shape of the pelvic outlet can affect the process of childbirth.

Anatomy

The pelvic outlet is bounded by the pubic arch in front, the ischial tuberosities laterally, and the coccyx (tailbone) at the back. The pelvic outlet is the lower part of the pelvic cavity, which is the space enclosed by the pelvis. The pelvic cavity contains and protects the urinary bladder, rectum, and in females, the uterus and ovaries.

Clinical significance

The size and shape of the pelvic outlet can affect the process of childbirth. A small or irregularly shaped pelvic outlet can cause difficulties during childbirth, such as dystocia (difficult labor). In such cases, medical intervention may be necessary, such as a cesarean section.

Etymology

The term "pelvic outlet" comes from the Latin pelvis, meaning "basin", and the Old French outlet, meaning "a way out".
