Mesovarium

The mesovarium is a part of the broad ligament of the uterus, which is a peritoneal fold that attaches the ovary to the posterior layer of the broad ligament. It serves as a conduit for the blood vessels, nerves, and lymphatics that supply the ovary.

Anatomy

The mesovarium is a short, almost horizontal peritoneal fold. It extends from the hilum of the ovary to the posterior layer of the broad ligament. The hilum is the point where the vessels and nerves enter and leave the ovary. The mesovarium is continuous with the mesosalpinx and the mesometrium, which are other parts of the broad ligament.

Function

The primary function of the mesovarium is to support the ovary and maintain its position within the pelvic cavity. It also provides a pathway for the ovarian artery, ovarian vein, and the ovarian nerve plexus to reach the ovary. Additionally, the mesovarium contains lymphatic vessels that drain lymph from the ovary to the para-aortic lymph nodes.

Clinical Significance

The mesovarium can be involved in various gynecological conditions. For instance, ovarian torsion can occur when the ovary twists around the mesovarium, cutting off its blood supply. This is a medical emergency that requires prompt intervention. Additionally, mesovarian cysts can develop, which may require surgical removal if symptomatic.
