"Prolonged foreskin is a very common andrology disease. Many men do not understand the dangers of overlong foreskin, or are unwilling to go to the hospital for examination due to reasons such as shyness and face saving, leading to diseases such as balanitis.". Some experts have pointed out that excessive foreskin may induce the generation of cancer.
"After puberty, a normal male has all or most of his glans exposed. If his glans cannot be exposed, the foreskin still covers all or most of his glans, but he can turn the foreskin up with his hand or turn the foreskin up after erection to reveal his glans, which is called excessive foreskin.".
There are four major hazards to an excessively long foreskin:
1. Causes penis inflammation: The sebaceous glands within the foreskin can secrete a large amount of sebum. If the foreskin is too long and is not discharged in a timely manner, the sebum and sediment in the urine form a cheesy, odorous foreskin scale that is suitable for bacterial growth and can cause inflammation of the penis and foreskin. Germs can also cause urinary tract infections through the urethra.
2. Impact on penis development: When young, the penis is wrapped and not stimulated, affecting development. When it becomes phimosis or incarceration in adulthood, it will be painful. In severe cases, the blood flow may be impeded and edema may occur, and even glans necrosis may occur.
3. Damage to renal function: Inflammation of the penis can cause stricture of the urethral orifice or anterior urethra, causing difficulty in urination. If urination is difficult for a long time, the function of the kidneys will be impaired.
4. Harmful to female reproductive health: Modern scientific research has shown that foreskin scaling is a carcinogen. According to surveys, 85% to 95% of patients with penile cancer have phimosis or excessive foreskin. "Prolonged phimosis and foreskin not only affect one's health, but also can bring foreskin dirt into the vagina to stimulate the uterus and induce cervical cancer if one sleeps with his wife.".
