The statement that male sterilization is not recommended does not exist. Male ligation refers to the ligation of the male vas deferens. The vas deferens is the tube that carries sperm outside the body. The main purpose of ligation is for contraception. Aside from the fact that it can lead to male infertility, male ligation is a safe and highly effective means of contraception. Ligation only blocks the sperm output channel and does not affect testicular sperm production or androgens, or the action of androgens, and therefore does not affect health or sexual function. The vast majority of men do not have any discomfort after the operation. Individuals may have complications such as localized pain in the scrotum and epididymal stasis; the ligation procedure may also cause bleeding, infection, pain, swelling, etc. However, all of the above conditions can be relieved after active treatment and the prognosis is good. Male ligation should go to a regular hospital for the procedure, and any adverse reactions after the procedure should go to the hospital in time and be treated under the guidance of the doctor.
