Intersystemic arterial anastomoses in testicles.
Anastomoses between three main vessels of the testes (testicular, cremasteric, and efferent duct arteries) at the level of the inguinal and scrotal parts of the spermatic cord are extremely rare. The role of these anastomoses in the maintenance of collateral circulation is negligible. A complex anatomical formation located near epididymis-efferent duct connection, where the three vessels are anastomosed (intersystemic junction of testicular arteries), is highly prevalent. This formation is presented by two morphological variants: closed and open vascular rings (semiring).
