The effects of ligation on men mainly include the following two aspects. First, the effect of local pain of male ligation on sexual physiological reflexes. Sexual function is a complex physiological process in which not only the synergy of a sound nervous system, endocrine system and reproductive system, but also the tacit cooperation between husband and wife. Vasectomy does not affect pituitary function and testosterone production after vasectomy, whether in the near or distant future. The presence of semen agglutination antibodies in the body will not harm the health either. The surgical trauma of epididymal stasis, paraphimosis and painful vasectomy all manifest with local pain. The pain inhibits the penile erection center through reflex, while the pain can be accompanied by unpleasant or hurtful feelings such as uneasiness and terror, which in turn deepen this will and lead to penile erection disorder. In addition, if the local pain is not obvious enough, but in the climax of sexual life, the strong contraction of the local muscles will also be painful, which is called ejaculation pain. Second, the psychological impact of male ligation. There are many reasons why ligation causes psychosexual disorder, and sometimes it may produce sexual life disorder. Some people themselves have neurosis, not suitable for ligation, post-operative sexual problems are more common.
