An internal diameter of 0.33 centimeters in the left varicocele is usually abnormal. The internal diameter of the spermatic vein is usually less than 0.18 centimeters. If the examination reveals that the internal diameter of the left spermatic vein reaches 0.33 centimeters, it may be a manifestation of moderate varicose veins, with the possibility of symptoms of pubic distension and pain, and the quality of sperms may also be affected. When the left varicocele reaches 0.33 cm, you need to pay attention to avoid sitting for a long time, and avoid eating spicy and stimulating foods such as chili peppers, onions, etc. Normally, you can do some outdoor activities to promote the return of blood in the spermatic vein, and if the varicocele continues to aggravate, you need to undergo a local surgery to repair the varicocele tissues. Varicose veins on the left side of the spermatic cord can have a certain impact on reproductive health, and need to take effective treatment measures as soon as possible to actively intervene, to follow the doctor’s instructions for the correct treatment and develop good living habits, in order to slowly return to normal.
