The foreskin is the layer of skin that surrounds the outside of the penis. Turning over the foreskin, it can be seen that the ring-shaped narrowing area behind the glans is called the coronal groove. "There are many sebaceous glands in the skin near the coronal sulcus, which secrete a smelly secretion in the form of yellowish white mud called" foreskin scaling. "".
Phimosis refers to the fact that the opening of the foreskin is too small to allow the foreskin to turn up and reveal the penis head; "Long foreskin means that the foreskin covers all of the penis, while the foreskin opening is not small and can be turned up to reveal the penis.". Long foreskin in infants and young children is often physiological, and it is only after puberty that the glans penis still cannot be exposed that it can be called phimosis or excessive foreskin.
"When phimosis or foreskin is too long, the secretion of the sebaceous glands within the foreskin cannot be discharged, and strange odor of foreskin scale gradually forms.". Scald on the foreskin is suitable for bacterial growth and can cause inflammation of the penis and foreskin. Inflammation that occurs at the urethral orifice can cause narrowing of the urethral orifice after healing, causing difficulty in urination. Prolonged stimulation of the penis by foreskin scale can also lead to penis cancer. It is reported that about 85% - 95% of patients with penile cancer have a history of phimosis or redundant foreskin. In addition, it is also extremely unfavorable for women. The husband's foreskin is too long, and the foreskin dirt enters the female reproductive tract, causing multiple long-term chronic irritation of the cervix, which may induce cervical cancer. Medical experts investigated Jews. Among the people who removed the foreskin after the birth of male babies, the incidence rate of cervical cancer in women was extremely low. Some people investigated residents on Peiji Island in the South Pacific Ocean and found that the incidence rate of cervical cancer in the former was 8 times higher than that in the latter through a comparative analysis of the wives of those who had not undergone circumcision and those who had undergone circumcision.
If phimosis is is not treated in a timely manner, the penis head will be locked tightly by the foreskin for a long time, resulting in poor development of the penis after puberty, and also affecting sexual life.
"If the phimosis and foreskin are too long and cannot be restored due to forced inversion, it can cause incarceration of the foreskin, and in severe cases, it can cause glans necrosis.".
Teenagers with phimosis or excessive foreskin should undergo circumcision as soon as possible. For non inflamed foreskin that is too long, as long as the foreskin is often turned upside down and cleaned, surgery may not be necessary.
