All the procedures involve occlusion of the testicular veins or pampiniform plexus.
Pathophysiology of varicocele Proposed Details mechanism Hyperthermia The scrotal position of the testicle allows for heat exchange between the pampiniform venous plexus and testicular artery regulating optimal temperature for spermatogenesis.
The fine network of the testicular veins in the pampiniform plexus evaluated by this study agrees with that described by different authors in bovines (HESS et al.
Functional arterio-venous anastomoses between the testicular artery and the pampiniform plexus in the spermatic cord of rams.
A peculiar case of bilateral, spontaneous thromboses of the pampiniform
Varicocele is an abnormal enlargement and tortuosity of the pampiniform plexus of veins in the spermatic cord.
The largest vein diameter and reversal blood flow of pampiniform plexus of veins were measured.
A further exception is epididymo-orchitis complicated by testicular infarction, which probably arises as a consequence of edema compromising venous drainage leading to thrombosis of the pampiniform
The spermatic cord also contains the testicular, cremasteric, and deferential arteries, pampiniform plexus, nerves, and lymphatics.
Varicocele represents abnormal dilatation and tortuosity of the veins of the pampiniform plexus within the spermatic cord, caused by incompetent valves in the internal spermatic vein.
Varicocele is defined as the dilatation of the pampiniform
plexus of veins surrounding the testis.
1] Consisting of a dilated and tortuous conglomeration of refluxing pampiniform
plexus veins, varicoceles are present in 15% of the general population, about 35% of men with primary infertility and 80% of those with secondary infertility.
