Male sterilization is actually a contraceptive method. If a man still wants to have a child after sterilization, he can actually do it through surgery, such as vasectomy reversal, and the success rate of this surgery is actually relatively high. 1. The vas deferens is relatively free in the scrotum and can be easily touched through a layer of skin. It feels like a matchstick. It is a hard and tough tube. It is accompanied by a bundle of soft tissue, which contains veins, arteries, and nerve fibers, collectively known as the spermatic cord in medicine. During the operation, only the vas deferens is ligated, while the blood vessels and nerves are kept intact. During the operation, the doctor uses the thumb and index finger of the left hand to pinch the vas deferens through the scrotal skin and slowly squeeze the tube under the skin, paying special attention not to pinch the contents of the spermatic cord. After injecting anesthetic into the local skin, the doctor uses a knife to cut a small incision of about half a centimeter in the skin, and then ties the two ends with silk thread. 2. Male sterilization is a permanent contraceptive method. The principle of contraception is to cut off the vas deferens that transports sperm from the testicles to the penis, so that sperm cannot enter the semen and is excreted from the body. This permanent contraceptive method is only suitable for couples who do not want to have children again. After a male sterilization operation, it will not immediately produce permanent contraceptive effects, so other reliable contraceptive measures must be used after the operation. Only after two sperm tests have been performed, it can be proved that there is no sperm at all, and then contraceptive measures can be abandoned. In very rare cases, the opened vas deferens will be reopened, thus restoring fertility. Generally, minor complications caused by the operation include wound swelling and pain. 3. If a man has undergone a vasectomy in the past and current conditions and policies allow him to have children again, he can undergo a vasectomy reversal, which has a high success rate. |
