This article is missing information about pampiniform plexus in female - the origin of the ovarian veins. Please expand the article to include this information. Further details may exist on the talk page.(November 2010)
In females, the pampiniform plexus drains the ovaries. The right ovary drains from the plexus to the ovarian vein and then to the inferior vena cava. However, the left ovary drains from the plexus to the left ovarian vein, and from there drains to the left renal vein before emptying into the inferior vena cava.
In addition to its function in venous return from the testes, the pampiniform plexus also plays a role in the temperature regulation of the testes. It acts as a heat exchanger, cooling blood in adjacent arteries. An abnormal enlargement of the pampiniform plexus is a medical condition called varicocele.
