How is varicocele caused?

Patient's question:

My profession requires long hours in front of the computer. Recently, I've been experiencing a heavy and distending sensation in my scrotum, with pain radiating to my abdomen and groin. After a thorough examination at the hospital, I was diagnosed with varicocele. It is said that this condition can lead to infertility, and I'm very worried! The help I'm seeking: How is varicocele caused?

Doctor's answer:

Varicocele Causes
Traditional Chinese Medicine believes that varicocele is caused by kidney deficiency, blood deficiency, cold coagulating blood, and external invasion of cold and dampness. This leads to the left spermatic vein being compressed by the sigmoid colon, as it is excessively long and lacks valves. Additionally, the internal spermatic artery crosses over the renal artery, and attention should be paid to varicocele or abdominal tumors, which may obstruct blood flow, causing blood clots to accumulate. This results in a heavy, distended scrotum and the exposure of varicose veins, resembling earthworms.
The above is a suggestion for this issue. It is hoped that it will be helpful to you. Wishing you a speedy recovery!
