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
that extends out from the ovary
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.

, ovarian plexus
, and lymphatic vessels.
In sum, the suspensory ligament consists of a single connective tissue from that has different regional notations, the peritoneum and the broad ligament.
One must understand that most of the abdominal cavity is lined by a double-membranous sac called peritoneum
. The interior is called the peritoneal cavity, this is the location of all 'intra-peritoneal' organs (disambiguation: retro-peritoneal organs ). The most inferior extent of the peritoneum covers the pelvic inlet
; in females, this region of the peritoneum is referred to as the 'broad ligament'.

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...

It contains the ovarian arteryOvarian 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...

Ovarian vein
The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery...

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.

Development
The suspensory ligament originates from the mesonephrosMesonephros
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...
