How long is the foreskin?

It is said that the foreskin is too long, so what is the foreskin too long? Experts say that the so-called redundant prepuce is a kind of male genital malformation. This kind of man's penis is wrapped in foreskin, and the glans penis is not exposed under normal circumstances. Some men can turn the foreskin back with the help of other places. So when it comes to this long problem, how long is the foreskin, which is considered to be beyond the normal value, and should it be called too long? Let's have a look. What is the normal foreskin length? Experts say that there is really no clear definition of the foreskin length of orthography. As long as the foreskin does not wrap the glans penis, the glans penis can be exposed normally, which does not affect the sexual life and feelings of men, and belongs to the normal foreskin length range. Generally speaking, men, especially men before the age of 7, have a long foreskin, covering the entire penis head and urethral orifice. With the development of youth, the size and length of penis are increasing, and the foreskin will shrink back, exposing the penis head and urethral orifice outside the foreskin. If the foreskin mouth is narrow after adulthood, or the foreskin and the penis head are still adhered, the foreskin can not be turned up, exposing the urethral orifice or penis head, which is medically called phimosis; If the foreskin can show the glans, but the foreskin mouth is small and does not cover the external urethral orifice, it is said that the foreskin is too long. What are the hazards of long foreskin? 1, hiding evils and accommodating filth, prone to urogenital inflammation: there are rich sebaceous glands in the foreskin and a lot of secretions. The foreskin prevents secretion from being discharged, accumulates into scales, and is parasitic with many pathogenic bacteria. Bacterial invasion of urethra can cause urinary tract infection, dermatitis, balanitis and urethritis, and increase the infection rate of genital warts, herpes and other sexually transmitted diseases. 2, hinder the development of penis, affect the harmony of sexual life: in adolescence, because the penis head is firmly wrapped by the foreskin, it can not be stimulated by the outside world, and the development of the penis head is greatly constrained. Adults will affect their normal sexual life because their foreskin is too long or phimosis. Especially for men whose foreskin is too small, it can't be recovered when the foreskin is turned up, and the foreskin is firmly stuck in the coronal groove, resulting in incarcerated phimosis, which is not very painful. 3, leading to impotence, premature ejaculation, male infertility and other diseases: because the glans mucosa is usually stimulated less, the nerve feeling of the glans mucosa is too sensitive, and the friction between the glans and the vagina is vented when sexual life is on the verge, causing pain. It will also reduce sperm vitality and semen viscosity due to premature ejaculation, inflammation, impotence and non-ejaculation, leading to infertility. 4. Endangering women's reproductive health and disease rehabilitation: male skin scales are an important cause of female cervical cancer. The skin is covered with all kinds of bacteria. After being brought into the vagina during sexual life, it causes repeated infection of gynecological diseases in women, stimulates the uterus and induces cervical cancer, which is an important reason for the malignant transformation of female cervix.
