Hello, phimosis prepuce is a common phenomenon among male friends. This situation will have a bad influence on men's sexual life and physical health, so we should pay attention to it and have a clear understanding of its harmfulness in time. For this problem, phimosis will cause phimosis incarceration, that is, when the phimosis mouth is not very small, the penis will erect and the glans penis will sometimes be exposed, but the narrow foreskin will be stuck in the coronal groove of the penis like a ring. Local blood circulation is blocked, which will lead to the occurrence of foreskin incarceration, and some distal tissues of foreskin incarceration will be ischemic and necrotic, leading to serious consequences. It is recommended to go to a regular specialist hospital, check according to the doctor's advice, and don't treat blindly. I wish you health.
