It is possible for a man to regain his fertility after a vasectomy, but this usually requires surgery and may also require assisted reproductive technology. If a man wants to have children after a vasectomy, he needs to undergo surgical treatment, such as microscopic vasectomy-vasectomy anastomosis, which cuts off the originally ligated vas deferens and then anastomoses the severed ends under the microscope. Of course, even if the vasectomy reset is successful, whether or not fertility can be restored depends on whether or not the quality of one’s own semen is qualified. If the quality of semen is good, fertility can be restored, but if there is poor semen quality, fertility may be affected, and assisted reproduction technology may even be needed to help complete fertility.
