? The decision of male circumcision varies from person to person. If the foreskin does not cause trouble during sexual behavior, there is no need for surgery. Too long foreskin usually means that the glans penis is completely wrapped under the skin when the penis is weak, but after the penis is erect, the glans penis is still invisible. In this case, it is necessary to find a doctor in Xi 'an andrology hospital to remove the long foreskin. ? Circumcision is to avoid the harm of long foreskin. The harm of too long foreskin is: 1, which hinders the development of penis and affects the harmony of sexual life; 2, make the penis inflamed: there are rich sebaceous glands in the foreskin, which can secrete a lot of sebum. Skin scales are suitable for bacterial growth, so it will cause inflammation of the penis head and foreskin. 3, damage to renal function: due to penis inflammation, it can cause urethral orifice or anterior urethra stenosis, resulting in dysuria. Long-term dysuria will damage the function of the kidney. 4, there is a risk of cancer: the foreskin is too long and phimosis may induce penile cancer.
