Ligation for men will not cause any significant health effects. Ligation surgery is only a minimally invasive procedure, in which the vas deferens is ligated under local anesthesia, blocking the sperm from exiting the body through the vas deferens, thus achieving the purpose of contraception. However, there may also be problems such as post-operative infections, recurrent problems and failure to produce competent sperm. Minimally invasive surgery is shorter and less invasive, postoperative recovery is quicker, and there are fewer postoperative complications. 1. Post-operative infection: If there is obvious swelling in the scrotum after the surgery, there may be an infection, but this phenomenon is relatively rare, and after a few days of rest after the follow-up treatment, it can return to normal, and will not have a great impact on the patient. However, it may have a certain impact on the patient’s psychology, so that the patient has sexual dysfunction or premature ejaculation. It is necessary to have timely psychological counseling with the patient to eliminate the patient’s psychological barriers. 2. Problems of recanalization: if there is a request to have children again after vasectomy, it is necessary to restore the semen to the normal condition after vasectomy to have children again, but the surgery has a certain risk of failure, such as after the surgery, local scar formation still leads to obstructive azoospermia can not give birth to a child again, and vasectomy can not be 100% successful recanalization. 3. Unable to produce qualified sperm: and ligation for a long time, even if the restoration of the testicles can not produce qualified sperm. After the ligation, patients should not overwork, pay attention to rest, and should not have sex within 15 days to avoid wound disintegration. In addition, patients also need to pay attention to personal hygiene, do not wear tight pants, and change underwear to prevent infection.
