Lymphovascular Supply

The blood supply to the ovary is from the ovarian artery, a branch of the aorta. This courses along the surface of the ovary and anastomoses with the ovarian branch of the uterine artery. Subsidiary branches enter the ovarian hilus and then travel through the medulla and cortex, anastomosing to form capillary channels. Veins accompany the arteries and in the hilum form a plexus which drains into the ovarian vein. The ovarian veins course along the surface of the ovaries, the right draining into the inferior vena cava and the left into the left renal vein.

The ovarian lymphatics originate with the theca layers of the follicles and course through the ovarian stroma to form a hilar plexus. Eventually they accompany the ovarian vessels to drain into the upper para-aortic lymph nodes at the level of the lower pole of the kidney.
