Pampiniform plexus

Last revised by Yvette Mellam on 10 Oct 2023

The pampiniform plexus (plural: plexuses) is the venous network of approximately 10 veins draining the testis and epididymis in males, and the ovary in females.

In males, the plexus surrounds the testicular artery in the spermatic cord and lies anterior to the ductus deferens. Each network coalesces to form the testicular (internal spermatic) veins.

Along with the cremaster and dartos muscles, the pampiniform plexus contributes to the testicular thermoregulatory system.

In females, the plexus draining the ovary is found within the broad ligament adjacent to the ovary and fallopian tube. Each network coalesces to form a singular ovarian vein for each ovary.
