Anatomy of the Ovary
The ovary is an elliptic paired organ, each located within close proximity to the central uterus. Although its size may vary depending on the number of follicles housed within it at one time, the adult ovary surfaces approximately 3-5cm in length, 1.5-3cm width, 0.6-1.5cm thickness and around 5-8g in weight. Its pale pink exterior is held within the pelvic girdle by three main structures; the mesovarium, ovarian ligament and suspensory ligament. The mesovarium is responsible for the attachment of the ventral ovary to the dorsal aspect of the broad ligament which it lies anterior to. Medially, the ovarian ligament maintains the ovaries proximity to the uterus anchoring each to either side. Finally, the suspensory ligament holds each of the ovaries superior aspect to the lateral pelvic wall.

Upon dissection, the ovary can be seen to maintain zones; an outer cortex, inner medulla and hilus. Most distally, the outermost layer of the ovary is delicate and thin, often exposing visible structures within deeper layers, this is because the superficial cortex houses considerably more dense and fibrotic tissues than other zones. Additionally, its thought that the outer surface becomes considerably more fibrotic with maturation and age. Follicles and their associated structures, such as the corpus luteum and follicular cysts are found to reside in the cortex and medulla.

Blood supply
The ovarian hilus is important for the blood supply of the ovary. It is where the suspensory ligament attaches to the ovarian surface and the main source of blood and nerve supply to the ovary. The main blood supply is composed of the ovarian artery, a branch of the aorta that runs parallel to the suspensory ligament and additionally a branch of the uterine artery that it combines with before anastomosis occurs. Alongside the ovarian arteries, the ovarian veins run with the right draining into the inferior vena cava and the left into the left renal vein.
