The ovarian ligament (also called the utero-ovarian ligament or proper ovarian ligament) is a fibrous ligament that connects the ovary to the lateral surface of the

uterus The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The ...

Structure

The ovarian ligament is composed of muscular and fibrous tissue; it extends from the uterine extremity of the ovary to the lateral aspect of the

uterine tube The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uteru ...

rather than a fibrous ligament. Specifically, it is located in the

parametrium The parametrium is the fibrous and fatty connective tissue that surrounds the uterus. This tissue separates the supravaginal portion of the cervix from the bladder. The parametrium lies in front of the cervix and extends laterally between the lay ...

Development

Embryologically, each ovary (which forms from the gonadal ridge) is connected to a band of mesoderm, the

gubernaculum The paired gubernacula (from Ancient Greek κυβερνάω = pilot, steer) also called the caudal genital ligament, are embryonic structures which begin as undifferentiated mesenchyme attaching to the caudal end of the gonads (testes in mal ...

. This strip of mesoderm remains in connection with the ovary throughout its development, and eventually spans this distance by attachment within the

labia majora The labia majora (singular: ''labium majus'') are two prominent longitudinal cutaneous folds that extend downward and backward from the mons pubis to the perineum. Together with the labia minora they form the labia of the vulva. The labia majo ...

. During the latter parts of urogenital development, the gubernaculum forms a long fibrous band of connective tissue stretching from the ovary to the uterus, and then continuing into the labia majora. This connective tissue span, the remnant of the gubernaculum is separated into two parts anatomically in the adult; the length between the ovary and the uterus termed the ovarian ligament, and the longer stretch between the uterus and the labia majora, the round ligament of uterus.

Function

The ovarian ligament anchors to the

ovaries The ovary is an organ in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it may become fertilized by a sperm. There is an ovary () found on each side of the body. T ...

uterine horn The uterine horns (cornua of uterus) are the points in the upper uterus where the fallopian tubes exit to meet the ovaries. They are one of the points of attachment for the round ligament of uterus (the other being the mons pubis). They also provi ...

Clinical significance

The ovarian ligament may be stretched by particularly large ovarian cancers and other masses.

History

The ovarian ligament is present in other
