What is a normal foreskin?
The skin over the tip of penis normally folds on itself as a sleeve and attaches to the head of penis. This extra skin is called foreskin. In newborn babies the under surface of the foreskin is fused to the head of penis. Because of this in 95% of newborn babies the foreskin can not be pulled back.
This is referred to as ‘physiological phimosis’ or ‘non retractile foreskin’. However as they get older it separates slowly; by 5 years of age, 50% of boys have a foreskin that can be pulled back; and by 15 years almost 90% have normal adult pattern.
