one of a pair of veins that emerge from convoluted plexuses in the broad ligament near the ovaries and the uterine tubes. The veins from each plexus ascend and unite to form single veins. The right ovarian vein opens into the inferior vena cava and the left ovarian vein into the renal vein. In some individuals the ovarian veins contain valves and greatly enlarge during pregnancy. Compare testicular vein.
In females, any of the veins that accompany the ovarian artery and that drain the ovary and Fallopian tube. Outside the broad ligament, the ovarian veins collect into two veins on each side of the body. These veins accompany the ovarian artery and merge into a single vein; the right ovarian vein then empties into the inferior cava (below the renal vein), while the left ovarian vein empties into the left renal vein.
