According to pop q, i have stage 2 cystocele that is contained inside.how will estrogen cream help this not progress further?

Topical estrogen: cream can often improve some symptoms due to pelvic organ prolapse with resulting incontinence by returning estrogen to the surrounding tissues resulting in less dryness and irritation. But it does not/can not actually change the mechanical progression of prolapse. A stage 2 cystocele may be improved with pelvic floor exercises, especially using biofeedback, or a pessary. Surgery may be needed.
