The mesovarium is a fold of the broad ligament of the uterus that attaches to the ovaries. It plays a role in supporting the ovaries, providing them with blood supply, and helping maintain their position in the pelvic cavity. While “mesovarium dysfunction” is not a widely recognized or commonly used medical term, some women may experience issues related to the structures and functions the mesovarium is involved in. This can include problems with blood flow, nerve supply, inflammation, or the overall support of the ovary.

Mesovarium Dysfunction can be understood as an umbrella term describing any structural, functional, or inflammatory problem affecting the mesovarium or the surrounding tissues. These problems may include:

Impaired blood flow to or from the ovary
Nerve-related issues affecting ovarian sensations and functions
Structural abnormalities that compromise the support or position of the ovary
Inflammatory or infectious processes that involve the mesovarium’s tissues

Because the mesovarium is closely tied to the ovaries, any dysfunction here may influence ovarian function and could lead to pelvic pain or other gynecological symptoms.

Pathophysiology (How Mesovarium Dysfunction Develops)

The pathophysiology of mesovarium dysfunction involves understanding how any disruption in blood supply, nerve pathways, inflammation, or structural support can lead to symptoms. Here is a simplified overview:

Blood flow issues: The mesovarium contains blood vessels that supply the ovaries. Reduced blood flow due to narrowing, twisting (torsion), or blockage can lead to ovarian pain or compromised ovarian function.
Nerve supply dysfunction: Nerves running through or near the mesovarium can be irritated by inflammation, compression, or scar tissue, leading to pain or abnormal sensations.
Structural problems: The mesovarium helps hold the ovaries in place. If ligaments become weak or overextended, the ovary’s position might be disturbed, possibly causing pelvic discomfort or an increased risk of ovarian torsion.
Inflammation or infection: Pelvic inflammatory disease (PID), endometriosis, or other inflammatory conditions can affect the mesovarium, leading to swelling and pain. Prolonged inflammation may result in scar tissue formation or adhesions.

When these factors interfere with normal ovarian function, it can lead to pelvic pain, reproductive challenges, or hormonal imbalances.

Structure of the Mesovarium

The mesovarium is one part of the broad ligament, which is divided into three main sections:

Mesometrium: The largest portion of the broad ligament, covering the uterus.
Mesosalpinx: The fold of the broad ligament that encloses the fallopian tubes.
Mesovarium: The portion of the broad ligament that connects to the ovary.

Key features of the mesovarium’s structure include:

A thin, double-layered peritoneal fold extending from the posterior layer of the broad ligament to the ovary.
It contains blood vessels, lymph vessels, and nerves supplying the ovary.
It helps maintain the position of the ovary within the pelvic cavity.

Blood Supply

The ovarian artery and the uterine artery are primarily responsible for supplying blood to the ovary and its surrounding structures, including the mesovarium.

Ovarian artery:
- Arises from the abdominal aorta.
- Travels through the suspensory ligament of the ovary (infundibulopelvic ligament) and then branches into vessels that enter the mesovarium.
- Supplies oxygen-rich blood to the ovary.
Uterine artery:
- Branches from the internal iliac artery.
- Sends smaller branches toward the ovary through the broad ligament.
- May also contribute to the blood supply of the mesovarium region.
Venous drainage:
- Ovarian veins drain the blood from the ovaries back toward the heart.
- The right ovarian vein drains directly into the inferior vena cava, while the left ovarian vein drains into the left renal vein.
- Proper venous drainage is essential to avoid congestion in the ovarian tissues.

Nerve Supply

Nerves supplying the ovary and the mesovarium typically arise from the ovarian plexus and the uterine plexus, which in turn receive fibers from the sympathetic and parasympathetic nervous systems.

Sympathetic fibers:
- Originate from the T10–T11 spinal segments.
- Regulate blood vessel constriction and other autonomic functions within the ovary.
Parasympathetic fibers:
- Arise from the pelvic splanchnic nerves (S2–S4).
- Contribute to regulating blood flow and some aspects of ovarian function.
Sensory innervation:
- Carries pain and other sensation signals from the ovary and mesovarium to the spinal cord.
- Dysfunction or irritation of these nerves can lead to pelvic pain or discomfort.

Functions of the Mesovarium

The mesovarium has several important roles in female pelvic health:

Support: Helps keep the ovary in its correct position within the pelvic cavity.
Pathway for blood vessels and nerves: Acts as a conduit for arteries, veins, lymphatic vessels, and nerves to reach the ovary.
Protection: Because it is a fold of peritoneum, it provides some degree of shielding from infections and friction.
Coordination with other pelvic organs: Works alongside other ligaments (such as the ovarian ligament and suspensory ligament) to maintain the integrity of the reproductive system.

Types of Mesovarium Dysfunction

Mesovarium dysfunction can vary depending on the underlying cause and how it affects the tissues. Some examples include:

Inflammatory mesovarium dysfunction: Caused by infections or conditions like PID.
Structural mesovarium dysfunction: Related to weakened ligaments or abnormal anatomical variations.
Vascular mesovarium dysfunction: Stemming from blood flow issues such as torsion or vascular compression.
Neurological mesovarium dysfunction: Involving nerve compression or nerve inflammation.
Endometriotic mesovarium dysfunction: Occurs when endometrial-like tissue grows in or around the mesovarium.
Adhesive mesovarium dysfunction: Scar tissue or adhesions limiting normal movement and function.

These “types” are not official medical labels but rather helpful ways to categorize the underlying issues that could affect the mesovarium.

Possible Causes of Mesovarium Dysfunction

Pelvic Inflammatory Disease (PID): Infections in the reproductive tract that inflame surrounding structures.
Endometriosis: Endometrial-like tissue growing on or near the mesovarium.
Ovarian Torsion: Twisting of the ovarian ligament and mesovarium, cutting off blood supply.
Adhesions: Scar tissue formation after surgery, infection, or endometriosis.
