In China, a country with a feudal history thousands of years ago, the hymen carried much happiness and remorse for women, representing not only purity and fidelity, but also morality and worldliness. For a variety of reasons, a woman who has a broken hymen can cause psychological barriers. Men who feel that their sexual spouse is not seeing red for the first time can also develop psychological barriers. As a result, young women will have multiple reasons for their desire for hymen repair. But does the hymen only serve this purpose and no other function? What is the function of the hymen? The hymen is the membranous tissue of the external vaginal opening and is rich in blood and nerves. The hymen of a young woman has a specific physiological function. If the labia majora and labia minora are the two barriers that protect a woman’s urethra and vagina, then the hymen is the most triple and tightest barrier that protects a woman’s vagina. Under normal conditions, the left and right halves of the ring-shaped hymen are always closed like lips, unaffected by the opening and opening of the legs. Therefore, no impure water from the outside can enter the vagina when a woman is swimming or taking a bath. Menstrual blood and vaginal secretions can only flow out of the body through the hymenopore in one direction. The hymen can only be slightly opened with the help of the hand. Therefore, the previous view that the hymen has no physiological function is wrong. Especially for prepubescent women, the reproductive organs are not yet well developed and the mucous membrane of the vagina is weaker and less acidic, thus unable to stop the invasion of bacteria. The hymen is thicker at this time and takes on this role to protect the female reproductive system. What is the whole process of hymenoplasty? The hymen can be broken after sex in mature women, or it can be broken without having sex, for example, if the hymen is hit during strenuous exercise. The process of hymen repair surgery is generally divided into the following aspects: Pre-operative 1, hymen repair surgery before a comprehensive gynecological examination, if women have vaginitis or sexually transmitted diseases, must be treated first, must wait for the completion of inflammation to eliminate a moment to carry out this surgery to ensure the normal operation. The best time for hymen repair surgery: hymen repair surgery should avoid the menstrual period, surgery is generally scheduled three days after the menstrual period to ten days before the menstrual period is better, that is, any day between three days after the menstrual period to ten days before the menstrual period can be scheduled hymen repair surgery. In surgery, hymenoplasty is a cosmetic surgical procedure to restore or recreate a new hymen that has been damaged. Hymenoplasty is a delicate plastic surgery. The basic principles are minimally invasive incision, bloodless operation, anatomical repositioning, fine suturing, and scarless post-operation. The entire procedure is safe, efficient and private. The hymen can be broken in one place or, more commonly, in multiple places. In most cases, the breakage is relatively regular, but in a few cases, the breakage is severe and the shape is extremely irregular, which can cause some difficulties in the repair surgery and can only be repaired by reconstructive methods. At present, we have achieved perfect results with minimally invasive fine surgery techniques to repair the hymen. Usually the vulva and vaginal opening are disinfected with 0.1% Neosporin or iodophor disinfectant, anesthetized with 1% lidocaine local infiltration, the hymen is cut out with small ophthalmic scissors to create a neat wound edge, and sutured with nylon thread or absorbable sutures so that the hymen is left with only a small finger hole, and a little antibiotic ointment is applied after surgery. For those who have more sexual intercourse, the surgery is a little more complicated, requiring a labia minora flap on the side or both sides of the vaginal opening to narrow the opening. Regardless of the method, the patient is basically painless during the surgery, and the surgically reconstructed hymen is usually restored to its original state in one to two months. However, it is forbidden to ride a bicycle or ride with exaggerated movements during this period to avoid re-tearing. After surgery 1, oral antibiotics to prevent infection after hymenoplasty. Take a sitz bath with 1/5000 of potassium permanganate solution twice a day for 7 days. 2, do not take aspirin and anti-inflammatory substances, do not smoke. 3.Minimize activities within one week after surgery, and avoid strenuous exercise within one month after surgery. 4.Avoid squatting as much as possible within half a month after surgery, and do not separate your legs too much. Try to reduce activities and avoid cycling and other activities that increase tension in the perineum. Finally, the author believes that although hymenoplasty has certain medical ethical and moral controversies, it can still restore women’s self-confidence and self-esteem to a certain extent, and the psychotherapeutic effect of hymenoplasty is greater than the role of the surgery itself.
