Surgery for men with ligation usually refers to bilateral vasectomy, which is used for family planning purposes by ligating both vas deferens to make it difficult for sperm to be transported. The procedure involves locating both vas deferens under local anesthesia, severing them and ligating each of the two severed ends. One severed end may also be encased in soft tissue under the skin to reduce the likelihood of recirculation. Generally, there is no need for special supervision after the operation, protect the wound and leave the hospital on the same day if there is no abnormal symptom, and semen analysis should be carried out as prescribed by the doctor within 3 months after discharge to confirm whether there is any complication as well as whether there is any presence of spermatozoa. After the operation, you should rest in bed for at least 1 day, reduce activities, keep the wound clean and dry, etc., so as to promote the early recovery of the wound.
