The symptoms of varicocele vary depending on the severity of the condition. Clinically, most patients with varicocele do not present distinct symptoms, or may not exhibit any symptoms at all, and the condition is often discovered during physical examinations. However, a small number of varicocele patients do exhibit clearly discernible symptoms, primarily presenting as discomfort or a heavy feeling in the scrotum on the affected side, especially after prolonged walking. Pain symptoms tend to worsen after such activities, but alleviate or even disappear after lying down and resting. These patients may also experience abnormal semen quality. For such cases, early surgical treatment is generally necessary. The surgery mainly involves high ligation of the spermatic vein, which helps relieve symptoms and is beneficial for the recovery of semen quality.
