Varicocele is the obstruction of venous reflux or valve failure in the spermatic cord that causes blood reflux and stagnation, resulting in tortuous expansion of the tracheal veins, the incidence of which is 10-15% in the male population. Patients with varicocele have distended scrotum when standing, with a feeling of heaviness and swelling, which may radiate to the lower abdomen, groin or lumbar region, aggravated when walking and working, and relieved after lying down and resting. During physical examination, varicose veins can be seen or felt in the scrotum as a mass of earthworms. In some patients, although there are no signs of varicocele, the lesions can be detected by ultrasound examination. Varicocele causes pathological changes in the testis, with delamination of the spermatogenic epithelium of the varicocele, disorganization and progressive reduction of spermatocytes and spermatocytes, reduction in the number of spermatozoa, and increase in the number of acromegalic, amorphous or immature spermatozoa. The main treatment for varicocele is high spermatic vein ligation. The rate of semen quality improvement after spermatozoal vein surgery can be 50-80%, and varicocele with infertility or semen abnormalities is an indication for surgery regardless of the severity of symptoms. Since the older the age, the longer the course of the disease, the greater the testicular damage. Some people even advocate that if varicocele is found in adolescence, it should be treated with surgery early so as not to affect future fertility. According to the patient’s specific situation, we can carry out inguinal, retroperitoneal and laparoscopic surgery respectively, with good results. Many patients have improved the quality of their semen after surgery and have fulfilled their dream of becoming a father.
