People with grade 1 to 3 varicocele should consult a doctor in a timely manner. Depending on the severity of the symptoms and the presence or absence of sperm abnormality, regular follow-up, conservative or surgical treatments such as high spermatic vein ligation may be chosen as prescribed by the doctor. If the symptoms are mild, you can choose to wear tight underwear or use scrotal braces. Mild patients with normal semen analysis should also be followed up regularly with routine semen analysis and testicular ultrasound every one to two years. If symptoms are severe and accompanied by sperm abnormalities, or if adolescent varicocele is accompanied by a reduction in testicular size, surgical treatment should be chosen. Currently, there are open surgery, laparoscopic high spermatic vein ligation and microscopic high spermatic vein ligation, of which microscopic high spermatic vein ligation is the preferred surgical method. With surgical treatment, some patients can improve sperm quality and restore fertility. If secondary varicocele is caused by compression of the spermatic vein by renal tumor or retroperitoneal tumor, or obstruction of venous return by cancerous embolus in renal vein or inferior vena cava, the primary disease should be treated actively, and the patient can have surgical treatments, such as tumor curettage and cancerous embolus removal. Grade 1-3 varicocele should be treated promptly and in accordance with medical advice.
