After a man is ligated, some will regain their fertility and some will not. Vasectomy usually refers to vasectomy surgery. After the surgery, sperms cannot be discharged normally, which will make men lose their fertility, and it is an effective form of contraception, which can provide long-term contraception and is relatively safe and effective. When a man has fertility requirements at a later stage, he can also consider undergoing vasectomy. If the vasectomy goes smoothly, the man will regain his fertility after a successful operation; however, there is a certain chance of failure in this kind of operation, after which the vas deferens can not be unblocked, and the man’s fertility can not be restored. Therefore, men need to consider all factors before undergoing ligation surgery, and should not blindly undergo ligation surgery.
