This is what I have slightly, not life threating but needs attention in the future.Maybe you may have same thing, they call it a bag of worms or speghetti around the left nut.
Varicocele is a mass of enlarged veins that develops in the spermatic cord, which leads from the testes (testicles) up through the inguinal canal (passageway in the lower abdominal wall) to the circulatory system. The spermatic cord is made up of blood vessels, lymphatic vessels, nerves, and the vas deferens (duct that carries sperm from the body). If the valves that regulate bloodflow from these veins become defective, blood does not circulate out of the testicles efficiently, which causes swelling in the veins above and behind the testicles.
A varicocele can develop in one testicle or both, but in about 85% of cases it develops in the left testicle. The left spermatic vein drains into the renal vein between the superior mesenteric artery and the aorta; these two arteries can compress the renal vein and thus impede bloodflow from the spermatic vein. The right spermatic vein drains into the vena cava (the vein that returns blood to the heart) and develops varicocele less often. A unilateral (one-sided) varicocele can affect either testicle.
Because of the impaired circulation of blood created by a varicocele, the blood does not cool as it does in a normal vein. The increased temperature of the blood raises the temperature of the testes, which is believed to contribute to infertility, as heat can damage or destroy sperm. The raised temperature may also impede production of new, healthy sperm.
Incidence and Prevalence
Between 10% and 20% of men past puberty have a varicocele; the sudden appearance of varicocele in an older man may indicate a renal tumor blocking the spermatic vein. Many men with varicocele do not have symptoms and do not experience infertility. Between 20% and 40% of all infertile males have varicocele. Among men with secondary infertility — those who have fathered a child but are no longer able to do so — the prevalence of varicocele is as high as 80%.
Causes
A varicocele develops when the valve that regulates bloodflow from the vein into the main circulatory system becomes damaged or defective. Inefficient blood flow causes dilation (enlargement) of the vein.
Signs and Symptoms
Most men who have a varicocele have no symptoms. Asymptomatic (symptom-free) cases are often diagnosed during a routine physical examination. Signs and symptoms may include the following:
Ache in the testicle
Atrophy (shrinkage) of the testicle(s)
Feeling of heaviness in the testicle(s)
Infertility
Palpably (evident to the touch) enlarged vein
Visibly enlarged vein
Recurrent or constant discomfort or pain in the genital region should be reported to a urologist or primary care physician to determine the cause.
