Spermatocele ligation usually has no obvious harm, but may be accompanied by complications such as vascular damage, testicular atrophy scrotal edema, infertility and so on. 1. Damage to the arterial vessels in the spermatic cord, which will seriously affect the blood supply to the testicles, thus resulting in testicular atrophy. 2. Combined local infection after the operation, triggering inflammatory reaction and causing scrotal edema and testicular syringomyelia. 3. Intraoperative laceration of the vas deferens or poor prognosis after the operation, resulting in damage to the vas deferens that prevents semen from passing through normally, thus causing infertility in the patient. In the case of spermatic vein ligation, it may be due to incomplete surgical ligation or the existence of lateral circulation not ligated, resulting in the re-vascularization of varicose after the operation. Therefore, it is necessary to strictly control the indications, go to regular hospitals for surgical treatment, and avoid physical exercise and sexual life in the short term.
