Mild varicose veins of the left spermatic cord cannot be cured spontaneously; mild varicose veins can be treated conservatively, while moderate to severe varicose veins can only be cured by surgical methods at present. Varicocele is a tortuous dilatation of the spermatic vein, which occurs in young and middle-aged men and is more common on the left side, accounting for 77%-92%. The main danger is that it leads to male infertility, but usually the symptoms are not obvious and are only detected during physical examination. If there is no scrotal enlargement, swelling, or hidden pain, it can be observed first without special treatment. However, if symptoms of scrotal swelling and pain occur and semen quality is not a problem, patients can relieve pain by applying local cold compresses, wearing tight pants, wearing scrotal braces, and if necessary, taking medications such as ibuprofen. If the symptoms are more serious and affect male fertility, high spermatic vein ligation surgery is needed in time. Patients should pay attention to control smoking and alcohol, eat a light diet, and reduce prolonged standing, sit-ups, heavy lifting, push-ups and other exercises that may increase abdominal pressure.
