Preface: Young couples do not like to have children too early, so many people choose condoms or medication to prevent pregnancy, and they are very resistant to male sterilization, fearing that it will do harm to men. Male sterilization is usually a vasectomy. The section of the vas deferens in the scrotum is relatively free, it is easy to feel through a layer of skin, and it is as thick as a matchstick when touched, it is a hard and tough tube. So, is there any harm in ligation for men? The effect of localized pain of ligation on sexual physiological reflexes Sexual function is a complex physiological process, in which not only the synergistic effect of a sound nervous system, endocrine system and reproductive system, but also the tacit cooperation of husband and wife are required. After vasectomy, there is no effect on pituitary function and testosterone production, either in the near or distant future. The presence of semen agglutination antibodies in the body also does not harm the health. The psychological impact of male ligation There are many reasons why ligation causes psychosexual disorders, the more common is to mistake ligation for castration; there are also some people who are relieved of the pressure of fear of pregnancy after ligation, overindulgence, and after a period of time produce sexual life disorders. Some people have neurosis and should not undergo ligation, and postoperative sexual problems are more common. Very few couples lose the risk of a possible pregnancy after ligation and instead feel that their sex life has lost its excitement. Where does a man’s sperm go when he is ligated? Male ligation is a very simple and safe procedure that works on the principle of cutting off or blocking the channels through which sperm are expelled from the body so that sperm production is not affected. As the transportation pipeline is cut off, the sperms cannot be exported, so they accumulate in the testicles and are reabsorbed without the slightest damage to the testicles. After ligation, there is still a normal ejaculation process during sexual intercourse and the same ejaculation pleasure can be felt, except that the semen does not contain sperm. The sperm production function of the testes is not affected and they still have the ability to produce sperm normally. Therefore, male ligation is not harmful to health and there is no need to worry too much. What if a man wants to regain his fertility after ligation? Male ligation surgery is to cut off the vas deferens, the tube that carries sperm from the testicles to the penis, so that the sperm cannot enter the semen and leave the body. Therefore, a man cannot have children after a vasectomy, but he can have a vasectomy if he wants to have children. Some people worry that they will not ejaculate after vasectomy, which will affect sexual pleasure, and there are also a few people who will experience different degrees of sexual dysfunction such as premature ejaculation after sterilization. Experts say that this is mainly a psychological reason, because you can ejaculate as usual after vasectomy, only that there are no sperms in the semen. Will ligation damage the testicles? Ligation does not damage the testicles, the testicular seminiferous tubules and interstitial cells can still continue to produce sperm and secrete sex hormones to maintain the normal sexual function of men, and to maintain the secondary sexual characteristics of men. Therefore, men who want to undergo vasectomy do not have to worry about the loss of sexual ability as well as premature ejaculation and impotence after vasectomy. Sexual pleasure will also not be affected after ligation because semen is a mixture of spermatozoa and seminal plasma, of which the seminal plasma secreted by the prostate, seminal vesicles and urethral bulbourethral glands accounts for 98% of the total volume. After vasectomy, it only cuts off the channel of sperm discharge, while the output of seminal plasma is still unobstructed.
