Suspensory ligament of the ovary
Encyclopedia
The suspensory ligament of the ovary, also infundibulopelvic ligament (commonly abbreviated IP ligament or simply IP), is a fold of peritoneum

Ovary
The ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system. Ovaries in anatomically female individuals are analogous to testes in anatomically male individuals, in that they are both gonads and endocrine glands.-Human anatomy:Ovaries...

 to the wall of the pelvis.

Some sources consider it a part of the broad ligament of uterus while other sources just consider it a "termination" of the ligament.

The suspensory ligament is directed upward over the iliac vessels.

It contains the ovarian artery
Ovarian artery
In human anatomy, the ovarian artery is a blood vessel that supplies oxygenated blood to the ovary. It arises from the abdominal aorta below the renal artery, and does not pass out of the abdominal cavity. It can be found in the suspensory ligament of the ovary, anterior to the ovarian vein and...

Composition

The suspensory ligament of the ovary is one continuous tissue that connects the ovary to the wall of the pelvis. There are separate names for the two regions of this tissue.
  • In the anterior region, the suspensory ligament is attached to the wall of the pelvis via a continuous tissue called peritoneum.
  • In the more posterior region, the suspensory ligament is attached to the ovary via a continuous tissue called the broad ligament.


In sum, the suspensory ligament consists of a single connective tissue from that has different regional notations, the peritoneum and the broad ligament.

Peritoneal relationship

; in females, this region of the peritoneum is referred to as the 'broad ligament'.

Development

The suspensory ligament originates from the mesonephros
Mesonephros
The mesonephros is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals. The mesonephros is included in the Wolffian body after Caspar Friedrich Wolff who described it in 1759...
