Children over 3 years old whose foreskin mouth is narrow and still cannot be turned up. 4. Patients with inflammatory adhesions between foreskin and penis head, which are difficult to separate by manipulation. Difficult. There are many benefits of circumcision, such as facilitating the development of children’s penis, improving the quality of adult male sex life, preventing the incidence of penile cancer, avoiding cross-infection between husband and wife, reducing the incidence of cervical cancer in the spouse, and preventing complications such as urinary tract infection or prostatitis.
