Project Description

This illustration depicts the vasculature of the testes. The inset, top right, provides an overview showing of the origin of the testicular arteries from the aorta and their course towards the testes. The main illustration shows the vasculature of the testes in more detail with the testes sectioned to show a lateral superior view. The testicular a. (shown black in both figures for emphasis) is the primary blood supply for the testes. It divides into 2-4 capsular arteries at the mediastinum of the testes that pierce through the visceral layer of tunica vaginalis. They then give off a centripetal aa. that feed each lobule in the testes.  The 3 different layers of the spermatic cord are depicted in the upper left of the main image. The illustration also shows two areas where anastomoses occur at the head and the tail of the epididymis to provide collateral circulation to the testes.
