The so -called foreskin refers to the two layers of skin in the inside and outside of the penis head. After entering the adolescence, the penis develops extremely rapidly.The mature penis should be stout, the head swells, and the glans are all naked. The foreskin is late to the penis body, but it is connected to the glans with the penis below the penis.Therefore, in addition to the increase in the entire volume, the main is the exposure of the glans.The phimosis is a narrow foreskin or a foreskin sticking to the penis head, so that the foreskin cannot be revealed to expose the penis head.The foreskin is too long covers all the penis head and urethral mouth, but it can still be turned up.
Excessive foreskin is extremely harmful to the body and is easy to accumulate under the foreskin of tofu -like foreskin dirt composed of sebaceous gland secretions and epithelium dandruff.Generally white and smell.Too long and foreskin can make the foreskin stacked under the skin.Foreskin stacked accumulation of bacterial infections, causing penile foreskinitis.Inflammatory adhesion can affect the loose foreskin, form a secondary phimosis, and even cause the urethral external stenosis.
Excessive foreskin is the "sickness" of penile cancer.The biggest risk of foreskin dirt may be that the penile head can cancer. In addition, the recurrence of the penis head foreskinitis is also an important factor that causes penile cancer.The stimulation of dirt such as bacteria, viruses, and falling epithelial cells in the long -term penile foreskin will increase the pathogenesis of penile cancer.In our country, the incidence of penile cancer is quite high, accounting for about half of the male urogenital tumor.More than 90%of penile cancer occurs in people with too long foreskin.The age of onset was earlier than most cancer.It can occur even before 20 years old.Because the foreskin is too common among men, and many people lack physiological hygiene knowledge, they do not pay attention to often opening foreskin and cleaning, which increases the incidence of penile cancer.
