★ small foreskin, can have a big role – born me “material” must be useful foreskin has a specific role, so, in the long process of human evolution has not degraded. The role of the foreskin is to protect the penis: the foreskin can be well attached to the head of the penis to play a role in sheltering the glans; in infancy can prevent the delicate urethral skin and diapers from direct friction damage, protect the penis from feces and ammonia pollution, but also to help prevent the invasion of pathogenic microorganisms. It can be said that the foreskin is the gatekeeper, to protect “me” and “you”. Foreskin role two, harmonious sex life: in sexual physiology, foreskin contains rich nerves, is the original source of excitement necessary for male adult sex; in the sex life, with the prevention of mucosal friction damage and painful intercourse, reduce the loss of vaginal secretions, stimulate the G-spot and other roles, help female spouses to achieve orgasm; in the process of sex, foreskin can protect the coronal groove from over-stimulation, to avoid In the process of sex, the foreskin can protect the coronal sulcus from excessive stimulation to avoid premature ejaculation. The foreskin is a small “tool”, and the price of “love” is even higher. ★Cut? To cut or not to cut? –The circumcision of children after the age of 5, if it still persists, can hinder the development of the penis, the foreskin secretion of the foreskin deposited in the foreskin cavity for a long time, can not be cleaned, long-term stimulation can cause inflammation of the foreskin and penis head, serious can also be due to The inflammation can cause adhesion of the foreskin and penis head, repeated infections induce urethritis, and even narrowing of the urethra, which will affect the discharge of urine and semen even after surgery. Therefore, any circumcision should be done. Circumcision can reduce male circumcision glansitis, foreskin stones and long-term or recurrent urinary tract infections; it can reduce the occurrence of penile cancer; it can reduce gynecological diseases of sexual partners after marriage, such as vaginitis, cervicitis, cervical erosion and cervical cancer; it can reduce the occurrence of sexual contact diseases, such as urethritis, genital warts and herpes. Most circumcised people, it is easy to turn up the foreskin by hand and expose the urethral opening and the entire penis head, if you can often pay attention to foreskin hygiene, no inflammation such as glansitis and urinary tract infections occur, it is not necessary to surgically remove the foreskin, such as every time you take a shower to turn up the foreskin and clean the inside and outside of the foreskin; if the cleanliness and hygiene is not enough, or more secretion of foreskin scale leads to frequent inflammation of the foreskin, surgery to remove the foreskin can “once and for all” to avoid trouble. If you need to be cut, you need to be cut! –Circumcision is “healthier”. For prepuce that still exists before puberty, it has been reported that 95% of children can be cured through the combination of external medication and foreskin traction. For children who have had infections, you can try to repeatedly turn up the foreskin and expand the foreskin opening first, and those who have been infected more than 3 times should be treated surgically. If the foreskin is still present at puberty, surgery is recommended to prevent it from affecting penile development. Although the foreskin can be turned over, but the outer foreskin is tight, the foreskin is difficult to retreat, adults are prone to foreskin imbedding during sex, requiring surgery. If the foreskin is embedded, you should go to the hospital in time for emergency treatment, so that you can get emergency treatment such as manual reset or dorsal penile stenosis ring incision, and then elective surgical treatment. The foreskin can be turned up, but there are tight adhesions between the foreskin and the head of the penis, resulting in the inability to forcibly turn up the foreskin. If the foreskin glansitis (left 1 below) occurs, do not flip and wash the foreskin in the acute stage, you can apply antibiotics appropriately, disinfectant solution repeatedly soak daily, recurrence of the author should be treated surgically after the inflammation subsides. The actual fact that you can’t cut, you must not cut! –The majority of children under 5 years of age are not operated on for circumcision. In addition to the fact that most of them can heal on their own, an important reason is the difficulty of choosing anesthesia. The risk of accidental general anesthesia is also a risk. For small penis, it is important to ask the doctor to check and exclude occult penis (4 on the left in the figure below), because children with occult penis should never be circumcised, and the foreskin is an important resource for the patient for future surgical treatment of the disease; for children with circumcision, before doing circumcision, some with hypospadias (5 on the left in the figure below) are not easily detected, and if found before or during surgery, the removal of foreskin should be terminated immediately. These are not a problem in experienced urologists. ★ At what age is it good to cut? –When to operate for pediatric circumcision and phimosis? There are still different understandings in domestic and international academic circles. Most domestic scholars and urologists do not advocate premature circumcision in childhood. Because of the pain and surgical complications associated with pediatric circumcision, simpler and more effective treatment methods are usually adopted, such as prepuce separation and expansion, without trimming the foreskin, separating the adhesions and removing the prepuce to ensure the normal development of the pediatric penis, and then circumcision after adulthood depending on the length of the foreskin. The best age for surgery is inconsistently reported, with some suggesting 5 to 7 years old, others suggesting 10 to 15 years old, and others suggesting that correction of circumcision should wait until the patient’s foreskin is mature (mostly at 17 years old) before proceeding. Clinically, doctors will decide whether surgery is necessary now based on the individual child’s condition.
