It is like an elastic hammock that supports the uterus, bladder and other pelvic organs. Pregnancy, childbirth, and age are all reasons that cause this hammock to become loose, resulting in symptoms such as stress urinary incontinence when laughing or coughing, and vaginal relaxation. Similarly, when muscle tension is high, it becomes very tight, and pelvic floor spasm, dyspareunia, and dysuria are common symptoms. Pelvic floor dysfunction is a common and highly prevalent disease for women, and has become one of the chronic diseases that threaten women's health and quality of life.
