We can sometimes see that a man's foreskin can't be turned over, not only naturally, but also by hand. This situation has existed for a long time, and the glans penis is not exposed, which also affects the beauty of the penis and affects sexual life. So what's wrong with men's foreskin not turning over? Pay attention to the phenomenon that the male foreskin can't be turned over, because your situation is either too long foreskin or phimosis. Excessive prepuce and phimosis are common phenomena, and phimosis is more harmful than excessive prepuce. Generally, children have phimosis, which will lead to foreskin inversion. However, with the increase of age, some people's penile erection will gradually be absorbed, but some people's phimosis will not disappear, so it will be solved by surgery. The harm of the foreskin not being turned over to men: 1, without ejaculation, the foreskin not being turned over. In this case, because the glans penis is over-protected by the skin, the rich nerve conduction stimulation and stimulation excitement of the glans penis disappear, and the stimulation intensity needed to stimulate ejaculation cannot be achieved in sexual life, so it is easy not to ejaculate. 2, make the penis inflamed: there are rich sebaceous glands in the foreskin, which can secrete a lot of sebum. After a long time, it will form "scale". Skin scales are suitable for bacterial growth, so it will cause inflammation of the penis head and foreskin. Bacteria can also cause urinary tract infection through urethra. 3, affecting the normal development of the glans penis: the foreskin can not be turned over to affect the normal development of the glans penis, and there will be serious glans deformity. 4, damage to renal function: due to inflammation of the penis, it can cause urethral orifice or anterior urethra stenosis, resulting in dysuria. Long-term dysuria will damage the function of the kidney. 5, carcinogenicity: potential dangers Many studies have shown that male skin scales (residual urine crystals) are one of the important reasons for male penile cancer and female cervical cancer.
