What is phimosis? "The foreskin completely covers the head of the penis and cannot be turned up to the coronal groove of the penis, which is called phimosis.". It can be divided into:
（1） Physiological phimosis: There is slight adhesion between the inner surface of the foreskin and the surface of the glans in newborns, which prevents the foreskin from turning over to the coronal groove. This type of phimosis is called physiological phimosis. Within 2-3 years after birth, it disappears naturally as epithelial adhesions are absorbed.
（2） Genuine phimosis: Refers to a person whose foreskin cannot be turned over to the coronal groove after the age of three. Sometimes the opening of the foreskin is as small as the tip of a needle, which hinders the development of the penis. During urination, urine accumulates within the foreskin, causing the foreskin to expand as a ball. "This type of phimosis requires circumcision before the age of 9, otherwise it can easily lead to foreskin balanitis and urethral stricture.". Accumulation of foreskin scaling can form foreskin scaling stones, and long-term stimulation can induce canceration. Chronic dysuria can affect renal function. Children can cause frequent urination and bedwetting at night.
（3） Secondary phimosis: In cases where the foreskin is too long, scar formation at the foreskin opening due to trauma and infection can result in narrowing of the foreskin opening, and the foreskin cannot be turned up. This phimosis is called secondary phimosis and requires circumcision.
"People with long foreskin or phimosis can easily cause inflammation of the foreskin or glans, leading to foreskin and glans inflammation.". However, we must pay attention to exclude diseases such as penis cancer and diabetes.
