In men, after puberty, all or most of the glans is exposed. If the glans cannot be exposed and the foreskin still wraps all or most of the glans, but the foreskin can be turned up or the foreskin can be turned up to reveal the glans after erection, it is called prepuce. The foreskin is genetically inherited and should be distinguished from the prepuce, which means that the foreskin covers the entire glans and cannot be flipped up and down, and the opening of the foreskin is very small. But regardless of circumcision or prepuce, there are certain harmful effects on the human body.
1, hinder the development of the penis, affecting sex life. The development of the penis will be affected by the circumference of the penis head during adolescence because the head of the penis is tightly wrapped by the foreskin and does not receive external stimulation. Adults will be due to the foreskin is too long or prepuce, foreskin tightly stuck in the coronal groove, become foreskin embedded. In serious cases, the glans will be edema or even glans necrosis due to poor blood flow.
2. Inflammation of the penis. When the foreskin is too long or circumcised, the sebaceous gland secretions within the foreskin cannot be discharged, and gradually form a foreskin scale. The foreskin scale is suitable for bacterial growth, so it can cause inflammation of the penis head and foreskin. The germs can also cause urinary tract infections through the urethra.
3, premature ejaculation. As the glans mucosa is hidden under the foreskin, the friction on the glans is reduced, making the glans mucosa nerve sensation too sensitive. When the glans is exposed after erection during sex, it will trigger premature ejaculation due to the sensitive nerves of the glans mucosa when it is rubbed and stimulated by the vagina.
4. Risk of cancer. Circumcision and prepuce have the possibility of inducing penile cancer.
