The normal pelvic organs in women, such as the bladder in front of the uterus, the rectum behind it, the vagina attached to it below, and the ureters on either side, that is, the surrounding pelvic organs and some of the fascia and muscles attached to it so that it can remain in such a position and not prolapse. Because there are no bones or skeletal muscles in the pelvic floor, it relies entirely on the cross action between the muscles to keep it in this state, so that it is located at the level of the sciatic spine at the external cervical opening, and does not prolapse down along the vagina. During labor, especially after a birth injury, the tension of the muscles and fascia decreases, especially when some injury occurs, such as a laceration injury, and its support is weakened, and some pelvic prolapse or anterior and posterior vaginal wall bulging, vaginal laxity, and other pelvic floor dysfunction can occur. By doing anal retraction, which is often called Kegel exercise, you can exercise the muscles of the anorectal muscle and increase its contraction force, and this also does not have to spend any money, and can be done anytime, anywhere, 2-3 times a day, each time in about 5-15 minutes can be. Repeated exercise can improve the contraction force of the anorectal muscles, increase the tension of the pelvic floor, reduce the occurrence of pelvic floor dysfunction disease, reduce urinary leakage, but also reduce the problem of gas, defecation difficulties, but also on the improvement of women’s sex life, to improve the quality of sexual life.
