In the case of circumcision, circumcision can be performed at an age greater than 3 years old because male children before the age of 3 years old are physiologically circumcised and do not need special treatment during this period as long as they do not cause obvious local symptoms of infection. If you have premature ejaculation, circumcision can be performed, or if you are overcircumcised, if you have recurrent local symptoms of infection and if there is an increase in prepuce or odor and a secondary urinary tract infection, you can be circumcised to prevent this disease from happening again. Therefore, circumcision can be performed at the age of 3 years old, after the period of physiological circumcision, or when the body has uncomfortable symptoms and for the treatment of specific diseases, such as premature ejaculation, circumcision can be performed, after which the sensitivity of the human body will decrease due to the nerve sensitivity caused by circumcision, thus being able to relieve the symptoms of premature ejaculation.
