In medicine, gonadal vein refers to the blood vessel that carries blood away from the gonad (testis, ovary) toward the heart. These are different arteries in women ( ovarian vein ) and men ( testicular vein ), but share the same embryological origin.
Since the left gonadal vein drains via the left renal vein, it can also result in left testicular pain [7] in men or left lower quadrant pain in women, especially during intercourse and during menstruation. [8] Occasionally, the gonadal vein swelling may lead to ovarian vein syndrome in women.
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. It can be found in the suspensory ligament of the ovary. [1]
The straight angle between the ovarian vein (or testicular vein in males in the case of varicocoele) and the renal vein has been proposed as a cause of decreased blood return. [citation needed] A related diagnosis is nutcracker syndrome where the left renal vein is described as being compressed between the aorta and the superior mesenteric ...
The term gonadal artery is a generic term for a paired artery, with one typically arising from the abdominal aorta for each gonad. [1] Specifically, it can refer to: the testicular artery in males; the ovarian artery in females
XY complete gonadal dysgenesis, also known as Swyer syndrome, is a type of defect hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal vulvas , [ 1 ] the person has underdeveloped gonads, fibrous tissue termed " streak gonads ", and if left untreated, will not experience puberty .
On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. [1] On the left, they drain into the renal vein which in turn drains into the inferior vena cava. [1] By contrast, all the lumbar veins and hepatic veins usually drain directly into the inferior vena cava. [1]
This triangle contains external iliac artery and vein, the deep circumflex iliac vein, the genital branch of genitofemoral nerve and hidden by fascia, the femoral nerve. It bears significance in laparoscopic repair of groin hernia. Surgical staples are avoided here. Similarly, the Triangle of Pain is an important landmark in laproscopic surgery.
