What is vaginal laxity: normal vagina is 2.5cm in diameter, 8cm long and can accommodate two fingers under laxity. There are many muscles and ligaments around the vagina to keep it under certain tension, and many folds in the mucous membrane of the vaginal wall to increase friction during sex. If the muscles are weakened, the muscles are torn, the ligaments are relaxed or the mucosal folds are reduced, the friction is weakened during sex and the pleasure is reduced or even disappeared for both men and women, which reduces the quality of life for both partners. This condition mostly occurs after vaginal delivery, after multiple deliveries or when the muscles around the vagina are torn or thinned due to the large fetal head, or when the vaginal lateral sutures are not fully and completely sutured, resulting in a wide and loose vaginal opening and a decrease in the contraction force of the vaginal mucosa, muscles and other soft tissues, as well as vaginal lacerations, old perineal tears and poor wound healing after lateral perineal incision. What is vaginal rejuvenation: Vaginal rejuvenation is a less complicated surgery that involves refolding and suturing the lax or torn muscles at the back wall of the vagina, reducing the diameter of the vagina and trimming the vaginal mucosa as appropriate to achieve a tightening effect. Pre- and post-operative precautions: No special preparation is needed before surgery. After surgery, keep the perineum clean, use PP powder to take a sitz bath, and prohibit sexual life for one month.
