Outside the male penis head, there is a double-fold penis skin, which is called foreskin. When the foreskin is turned over, it can be seen that the ring-shaped shrinking part behind the glans is called the coronal groove. There are many sebaceous glands in the skin near the coronal groove, which secrete a smelly secretion in the form of yellow and white mud, called "prepuce scale".
A man, especially before the age of 7, has a relatively long foreskin, covering the entire penis and the external orifice of the urethra. Later, with the development of youth, the volume and length of the penis will increase, and the foreskin will shrink back, exposing the penis head and urethral orifice outside the foreskin. If, in adulthood, the prepuce mouth is narrow, or the prepuce still adheres to the penis head, the prepuce cannot turn up and expose the urethral orifice or penis head, which is called phimosis in medicine; If the foreskin can turn up and reveal the glans, but the foreskin mouth is very small, covering the outside of the urethra, it is said that the foreskin is too long.
Among the adult men in China, 29% have long foreskin and 9% have phimosis.
Some people believe that phimosis and long foreskin do not hinder sexual life and fertility, so they are not a genital disease. In fact, this view is not scientific. Because, whether phimosis or foreskin is too long, it is harmful to human body.
(1) Obstruct the development of penis and affect the harmony of sexual life: phimosis will affect the growth and development of penis. In adolescence, because the penis head is tightly wrapped by the foreskin and cannot be stimulated by the outside world, the development of the penis head is greatly constrained, resulting in a significantly smaller circumference of the crown of the penis head after the maturity of sexual organs, affecting sexual pleasure. Adults will affect their normal sexual life due to long foreskin or phimosis. Especially for men with too small foreskin diameter, the foreskin can not be recovered, and the foreskin is tightly stuck in the coronary groove, forming embedded phimosis, which is not very painful. In severe cases, the glans will have edema due to poor blood flow, and even glans necrosis may occur.
(2) Inflammation of penis: there are abundant sebaceous glands in the foreskin, which can secrete a large amount of sebum. When the phimosis or foreskin is too long, the secretion of sebaceous glands in the foreskin can not be discharged, and the sediment in sebum and urine can form a cheese-like and smelly "foreskin scale". The foreskin scale is suitable for bacterial growth, so it can cause inflammation of the penis and foreskin. Bacteria can also cause urinary tract infection through the urethra. Inflammation at the urethral orifice can cause the urethral orifice to be narrow after healing, resulting in difficulty in urination.
(3) Damage to renal function: inflammation of the penis can cause urethral orifice or anterior urethral stricture, resulting in difficulty in urination. If urination is difficult for a long time, the function of the kidney will be damaged.
(4) There is a risk of cancer: the foreskin is too long and phimosis may induce penis cancer. Modern scientific research shows that foreskin scaling is a carcinogen. According to the survey, 85% - 95% of patients with penile cancer have phimosis or long foreskin. The phimosis and foreskin are too long, which not only affect your health, but also bring the foreskin dirt into the vagina, stimulate the uterus and induce cervical cancer if you sleep with your wife.
Therefore, men with phimosis and long foreskin should go to the hospital for surgery as soon as possible. Perform circumcision. For the long, non-inflammatory prepuce, as long as the prepuce is often turned up and cleaned, surgery is not necessary.
If there is inflammation that cannot be operated as soon as possible, the vulva should also be kept clean, and the penis should be cleaned once a day. Do not turn the foreskin with your hands, do not smear drugs indiscriminately, and do not believe in any "folk prescription". Please go to the hospital in time to ask the doctor for treatment, and then operate after the inflammation disappears.
