The gonadal veins are paired structures that drain the gonads in males and females. In males it is called the testicular vein (or internal spermatic vein) and in females it is called the ovarian vein. the right gonadal vein drains directly into the inferior vena cava. In medicine, gonadal vein refers to the blood vessel that carries blood away from the gonad (testis, ovary) toward the heart. The testicular vein--midway between the internal inguinal ring and the lower pole of the kidney--divides into the medial and lateral branch to form a delta. The medial branch communicates with the ureteral and contralateral veins; there, it terminates in the left renal vein or inferior vena cava on the right side. The right testicular vein attaches to the inferior vena cava. The left vein drains into the left renal vein. The left testicle is bigger than the right one; therefore, the left vein is longer than the right. This causes the blood to gather, leading to dilated (expanded) veins in the scrotum.

Gonadal dysgenesis. It is the defective development of the gonads in an embryo, with reproductive tissue replaced with functionless, fibrous tissue, termed streak gonads.

Nutcracker syndrome is a vascular compression disorder that refers to the compression of the left renal vein most commonly between the superior mesenteric artery (SMA) and aorta, although other variations can exist 1.

The great saphenous vein is a large venous blood vessel running near the inside surface of the leg from the ankle to the groin. It arises from the dorsal venous arch at the top (dorsum) of the foot and drains into the femoral vein, the main deep vein for the leg.

https://en.wikipedia.org/wiki/Internal_iliac_vein

The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.

https://en.wikipedia.org/wiki/Iliac_vein

In human anatomy, iliac vein refers to several anatomical structures located in the pelvis: Common iliac vein, formed by the external and internal iliac veins, drains into the inferior vena cava.

The pampiniform plexus is a loose network of small veins found within the male spermatic cord. The veins of the plexus ascend along the spermatic cord at the front of the ductus deferens. The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood.

External iliac vein. The external iliac vein (latin: vena iliaca externa) is a large vein formed by the femoral vein. The external iliac vein receives the inferior epigastric vein and the deep circumflex iliac vein. The external iliac veins drain blood from the muscles and skin in the lower abdominal wall.

The typical patient with ovarian vein thrombosis (ie, thrombophlebitis) presents with pelvic pain, fever, and a right-sided abdominal mass. The combination of anticoagulant and intravenous (IV) antibiotic therapy is the treatment of choice.

https://en.wikipedia.org/wiki/Common_iliac_vein

The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, forming the inferior vena cava. They drain blood from the pelvis and lower limbs.

https://en.wikipedia.org/wiki/Renal_vein

The anterior surfaces of the kidneys, showing the areas of contact of neighboring viscera. The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood filtered by the kidney.

Hepatic veins. Medically reviewed by Healthline's Medical Network on November 4, 2014. The hepatic veins carry oxygen-depleted blood from the liver to the inferior vena cava. They also transport blood that has been drained from the colon, pancreas, small intestine, and the stomach, and cleaned by the liver.

The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart. They're similar to arteries but not as strong or as thick. Unlike arteries, veins contain valves that ensure blood flows in only one direction.

The femoral artery starts in the lower abdomen and goes through the thigh, which is how blood is circulated through the legs. It ends around the back of the knee, as the artery then becomes a popliteal artery.
