Local foreskin infections (balanoposthitis) can occur at any age in uncircumcised males, but is most common at age 2-5 years, an age when the foreskin has often not yet completely separated, and cannot be fully retracted, and genital cleanliness is more difficult to accomplish. In addition between 0.5% and 1% of boys will never be able to retract their foreskin due to a pinpoint opening at the end (phimosis) and will have to be circumcised at a later date when the procedure is more complex and difficult, and about 10 times more expensive. Newborn circumcision leads to improved genital hygiene throughout life, but most importantly in infancy, early childhood and old age when personal hygiene may be inadequate. Uncircumcised males are more likely to develop a wide variety of skin disorders including psoriasis, lichen planus, and seborrhei eczema.
