Circumcision is a relatively common male reproductive deformity disease, bringing a great impact on men, seriously affecting the happiness of men’s lives. But if you say how much harm it does to men, I believe we are not very clear, let’s take a look: 1, impede penis development, affecting the harmony of the sexual life of couples: the prepuce will affect the growth and development of the penis, men in adolescence because the penis head is tightly wrapped by the foreskin, there is no way to get the outside world should be stimulated, the development of the penis head is greatly constrained, resulting in the development of sexual organs The circumference of the crown of the head of the penis after maturity is obviously small, affecting sexual pleasure. 2, easy to cause foreskin embedded: penis erection foreskin turned up after can not turn down, glans will be because of poor blood flow and edema, serious may lead to glans necrosis. 3, leading to inflammation of the penis: there are abundant sebaceous glands in the foreskin, which can secrete a large amount of sebum, the foreskin is too long so that the secretions of the sebaceous glands in the foreskin can not be discharged, it will become foreskin scale, foreskin scale is suitable for bacterial growth, so it will cause the head of the penis and foreskin inflammation, germs through the urethra can also cause urinary tract infection, inflammation in the urethra, after healing can cause the urethral opening narrow, causing urination difficulties for patients. 4.Risk of cancer: Circumcision and prepuce may induce penile cancer, and also affect women’s health. A large amount of bacteria from prepuce may be brought into women’s vagina and cause infection during sex, and the long-term stimulation of prepuce is also one of the factors leading to cervical cancer in women. 5. Damage to the function of kidney: Due to the inflammation of penis, it can cause the narrowing of urethra or front urethra, which will cause the patient to have difficulty in urination and lead to long-term difficulty in urination, so the function of kidney will be damaged.
