Uterosacral ligament

Uterosacral Ligament

The Uterosacral Ligament (also known as the sacrouterine ligament) is a part of the female reproductive system that provides support to the uterus. It is a fibrous cord that extends from the cervix and posterior part of the uterus to the sacrum, the triangular bone at the base of the spine.

Anatomy

The uterosacral ligament is a paired structure, with one ligament on each side of the uterus. Each ligament is approximately 5 cm long and is composed of smooth muscle, connective tissue, and nerve fibers. The ligaments are located in the posterior leaf of the broad ligament, a fold of peritoneum that supports the uterus, fallopian tubes, and ovaries.

Function

The primary function of the uterosacral ligament is to provide support to the uterus and help maintain its position within the pelvis. It also plays a role in sexual function, as it contains nerve fibers that contribute to sexual arousal and orgasm.

Clinical Significance

Damage or weakening of the uterosacral ligament can lead to pelvic organ prolapse, a condition in which the uterus, bladder, or rectum descends into the vagina. This can occur as a result of childbirth, aging, or other factors. Surgical procedures to repair or reinforce the uterosacral ligament can help treat pelvic organ prolapse.

Etymology

The term "uterosacral" is derived from "uterus," the Latin word for womb, and "sacral," which refers to the sacrum, the bone to which the ligament is attached.
