Structure

The ovarian arteries are paired structures that arise from the abdominal aorta, usually at the level of L2. After emerging from the aorta, the artery travels within the
suspensory ligament of the ovary 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 ...

Anastamoses

The ovarian artery may anastamose with the uterine artery in the broad ligament. This is thus an anastamosis between the abdominal aorta and the anterior internal iliac artery.


Branches

Small branches are given to the

Variance

In 20%, they arise from the renal arteries (inferior polar). Uncommonly they may arise from adrenal, lumbar, or internal iliac arteries.Chiva, L. M., & Magrina, J. (2018).

Function

The ovarian artery supplies blood to the
ovary The ovary () is a gonad in the female reproductive system that produces ova; when released, an ovum travels through the fallopian tube/ oviduct into the uterus. There is an ovary on the left and the right side of the body. The ovaries are end ...
and
uterus The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, f ...
. The ovarian arteries swell during pregnancy, in order to increase the uterine blood supply.
