Female pelvic organ prolapse is a complex mechanism combining the mechanical behavior of the tissues involved and their geometry defects. The developed approach consists in generating a parametric FE model of the whole pelvic system to analyze the influence of this material and geometric combination on median cystocele prolapse occurrence. In accordance with epidemiological and anatomical literature, the results of the numerical approach proposed show that the geometrical aspects have a stronger influence than material properties. The fascia between the bladder and vagina and paravaginal ligaments are the most important anatomical structures inducing the amplitude of cystocele prolapse. This FE model has also allowed studying the coupled effect, showing a significant influence of the fascia size. The study allows highlighting the origins of the median cystocele prolapse and responds to this major issue of mobility occurrence.
