Some men can regain their fertility after a ligation with a vasectomy, but their success rate is low. Male ligation usually refers to vasectomy surgery. After the ligation, as the ureter is disconnected, sperms cannot be discharged, which will make men lose their fertility. If a man has fertility requirements, he can undergo vasectomy. After successful vasectomy, sperms can be discharged normally, which may restore male fertility to normal. However, it should be noted that the success rate of vasectomy is low. Besides, if the sperms are normal, the man can have fertility through other means, such as in vitro fertilization (IVF).
