Primary varicocele. Most varicoceles are primary and result from incompetent or congenitally absent valves in the testicular vein (internal spermatic vein). The left testis is affected much more commonly (≈85%) than the right. This may be due to the shorter course of the right testicular vein and its oblique insertion into the IVC which ...Testicular torsion is defined as a twisting of the spermatic cord structures (see the image below), followed by venous congestion, loss of arterial inflow, and subsequent ischemia of the ipsilateral testis. This is considered a urologic emergency; it necessitates expeditious diagnosis and treatment to preserve testicular vitality.An overactive muscle causes a testicle to become a retractile testicle. The cremaster muscle is a thin pouch-like muscle in which a testicle rests. When the cremaster muscle contracts, it pulls the testicle up toward the body. The cremaster reflex can be stimulated by rubbing a nerve on the inner thigh and by emotion, such as fear and laughter.However, in patients referred for ultrasound for the investigation of conditions such as subfertility, cryptorchidism or a previous history of testicular cancer, which already increases the risk of testicular cancer, the presence of TM further increased the risk of testicular cancer with an estimated risk ratio of 8.5. 28 In another series of testicular …Testicular torsion occurs when a testis torts on the spermatic cord resulting in the cutting off of blood supply.
