It is possible for a man to regain his fertility after a ligation, which usually requires a vasectomy reversal, but some people may experience a failed reversal. If a man wants to regain his fertility after a ligation, it depends on whether there are adhesions at the site of the ligation and how well the testicles have recovered their ability to produce sperm. If the adhesions at the ligation site are severe, the vasectomy may fail even if the vasectomy is performed. However, if there is no adhesion at the ligation site, and the vas deferens is able to reach a smooth state after surgical recanalization, the effect of recanalization is achieved, and as long as the spermatogenesis of the testes is normal, fertility can be successfully restored. In addition, if a man has inflammation of the genitourinary system before the surgery, such as scrotal inflammation, eczema, lymphedema, etc., he can not do vasectomy, and needs to be cured before the surgery, and it is best for a man’s vasectomy to be performed within 5 years after the ligation, otherwise the success rate is very low. If the patient has the need, it is recommended to go to the regular hospital for relevant consultation and examination.
