Varicocele is an abnormal enlargement of the vein that is in the scrotum draining the testicles.
The varicocels affect 15-20% of men, usually between 15-30 years old. Development after the age of 40 is extremely rare.
Upward flow of blood in the veins is ensured by small one-way valves that prevent backflow. The formation of varicocele is typically related to defective valves or to vein compression of a nearby structure. You may feel pain within the scrotum, heaviness in the testicle, atrophy of the testicle(s) often accompanied by a feeling of a bag of worms- symptoms that may influence your sexual life as well as your normal erection process.
Varicocele can be most reliably diagnosed by Ultrasonography that will demonstrate back-flow in the spermatic veins
There are several treatments:
Surgery called Varicocelectomy is often performed
Using a method named The Gat-Goren nonsurgical method, a Fluid injected through a catheter selectively closes the malfunctioning veins, making possible the testicular tissues to recover and begin to produce normal sperm in normal amounts.
In Embolization method, the doctor can obstruct the veins so that the increased pressure that comes from the abdomen is no longer transmitted to the testicles, through a small flexible catheter. The risks compared to those of the surgery are minimal.Embolization is an effective treatment for varicoceles that appear after they have been once surgically fixed.
Medical treatment with L-carnitine has some beneficial effect, but is less effective than surgery.
