Which veins drain the reproductive organs?

The veins draining the reproductive organs are the gonadal veins. They carry blood from the ovaries or testes into the systemic venous circulation—typically the right gonadal vein drains into the inferior vena cava, while the left gonadal vein drains into the left renal vein. This is different from the other vessels listed: the azygos vein mainly drains the thorax and some posterior abdominal wall regions; the saphenous vein is a superficial vein of the leg; and the hepatic portal vein carries blood from the abdominal viscera to the liver as part of the portal system, not directly back to the heart from the gonads.
