-Your son's foreskin should be cut off in order to facilitate hygiene.
My experience as a pediatrician has convinced me that circumcision makes the penis dirtier, a fact that was confirmed by a study recently published in the British Journal of Urology.1 For at least a week after circumcision, the baby is left with a large open wound that is in almost constant contact with urine and feces--hardly a hygienic advantage. Additionally, throughout life the circumcised penis is open and exposed to dirt and contaminants of all kinds. The wrinkles and folds that often form around the circumcision scar frequently harbor dirt and germs.
Thanks to the foreskin, the intact penis is protected from dirt and contamination. While this important protective function is extremely useful while the baby is in diapers, the foreskin provides protection to the glans and urinary opening for a lifetime. At all ages, the foreskin keeps the glans safe, soft, and clean.
Throughout childhood, there is no need to wash underneath the foreskin. Mothers used to be advised to retract the foreskin and wash beneath it every day. This was very bad advice indeed. When the foreskin becomes fully retractable, usually by the end of puberty, your son can retract it and rinse his glans with warm water while he is in the shower."
And...
"-Your son's foreskin is red, inflamed, itching, and uncomfortable. It has an infection and needs to be cut off.
Sometimes the tip of the foreskin does become reddened. During the diaper-wearing years, this is usually ammoniacal dermatitis, commonly known as diaper rash. When normal skin bacteria and feces react with urine, they produce ammonia, which burns the skin and causes inflammation and discomfort. If the foreskin were amputated, the inflammation would be on the glans itself and could enter the urethra. When the foreskin becomes reddened, it is doing its job of protecting the glans and urinary meatus.
Circumcision will have no effect on diaper rash. Change your baby's diapers more frequently and use a barrier cream until the rash clears. Harsh bath soaps can also cause inflammation of the foreskin. Use only the gentlest and purest of soap on your child's tender skin. Resist the temptation to give your child bubble baths, because these are harmful to the skin. Never use soap to wash the inner foreskin because it is mucous membrane, just like the inner lining of the eyelid.
Foreskin infections are extremely rare, but if they occur, one of the many simple treatment options is antibiotic ointment along with bacterial replacement therapy (Acidophilus culture). We don't amputate body parts because of an infection. Most infections of the foreskin are actually caused by washing the foreskin with soap. Leave the foreskin alone, remembering that it doesn't need any special washing, and infections will be unlikely to occur. "
