1, the phimosis standard phimosis refers to the male after puberty, in the state of penile erection, the foreskin still cover the urethral opening in terms of. If the foreskin recedes from the urethral opening or the head of the penis extends out of the opening of the foreskin in the erect state, it should not be regarded as phimosis. The difference between long foreskin and long foreskin is in the word “over”, long foreskin does not necessarily need surgery, long foreskin is the need for surgical removal. 2, who want to do circumcision The indications for circumcision surgery are circumcision, recurrent phimosis, adherence to the tighter phimosis, narrowing of the opening of the foreskin and circumcision cysts. It is especially important to point out that patients with recurrent inflammation of the foreskin, circumcision cysts, tightly adherent prepuce with circumcision stenosis should be treated with early surgery regardless of their age. 3, types of circumcision circumcision is one of the simplest urological surgery. Surgical methods are commonly used instrument excision, the advantage is that the cutting edge is neat, only a small amount of bleeding, fast healing; laser knife excision, bleeding little or no bleeding, but the healing is delayed; electro-knife excision, ligature ring excision, anastomosis excision and so on. Regardless of the method used to remove the foreskin, the inner and outer foreskin plates must be sutured for healing. Several surgical methods have their own advantages and disadvantages, as long as the doctor who performs the surgery is skilled, which method can be used. 4, the foreskin scale male from birth to old have trace or small amount of foreskin secretion, youth period foreskin secretion more, into the middle and old age after reducing. Circumcision secretion is the normal secretion of male foreskin, not carcinogenic, otherwise “Creator” in the creation of mankind, why should the male foreskin in the long foreskin gland? Is it just to get penile cancer? Because the foreskin secretion contains lipoprotein substances, in the foreskin cavity when the accumulation of too much, will be subject to some enzymes and the human body resident bacterial decomposition, the formation of a kind of white material like dregs and a special smell and annoying, which is what people usually call the foreskin scale. Men do not have to worry about the foreskin scale, as long as the appropriate time to wash, maintain hygiene can be, do not have to eliminate the foreskin scale and cut the foreskin is not too long. 5, the best time to circumcise the circumcision of infants or children, as long as it does not affect urination, there is no need to prematurely do circumcision. Because the children’s penis has a development process, childhood, most children outdoor activities more, the penis by the trauma of the opportunity is also more, premature removal of the foreskin will lose the role of protection of the glans. Generally speaking, the foreskin will not affect the development of the penis, and it is most appropriate to remove the excessively long foreskin when the male sexual development is mature. Therefore, even if the foreskin is too long, it is ideal to remove it after puberty or before marriage. However, if the foreskin is obvious, in order not to affect the development of the penis, it is best to choose to deal with the foreskin before puberty is the most appropriate (11-13 years old). 6, whether circumcision can treat premature ejaculation in the circumcision 3 months follow-up found that the patient just after surgery exposed glans is particularly sensitive, in general life activities due to the friction of clothing and pants and make the penis erection, must stop the activity, can gradually subside. This phenomenon is most obvious at the beginning of the postoperative period, with the prolongation of time, and gradually reduce. This is due to the long foreskin for a long time to cover the glans and the coronal margin, its stimulation is less, the sensitivity is particularly high, the stimulation valve is particularly low, easy to form premature ejaculation. When circumcision, the glans penis and the coronal margin of the penis long-term exposure, long-term friction stimulation by clothing, repeated erection, fading, erection, and this stimulus are below the threshold, so that its sensitivity is reduced to break the original conditioned reflex, and gradually improve the trigger ejaculation center threshold, delay the emergence of ejaculation, prolong the time of intercourse, so in a sense, circumcision has a certain premature ejaculation So in a sense, circumcision has a certain therapeutic effect on premature ejaculation.
