What are the pros and cons of circumcision?

Circumcision is extremely controversial. I am against circumcision and other sorts of body modifications like piercings for infants who do not yet have the ability to voice out their decision. I gave birth to my daughter, but it does not give me the right to pierce her ears or modify her body without her expressed permission and intent. Medical professionals neither encourage or discourage routine circumcision for newborn males, so I would prefer not to do it. Instead, when I have a son in future, I would take extra care to clean his penis and teach him how to clean his own penis when he is able to do so. http://www.medicinenet.com/circumcision_the_medical_pros_and_cons/article.htm
