The incidences and prevalence of POP is difficult to determine, since many women do not seek medical advice and treatment for the condition. It has been estimated that half of women who have given birth lose some of the pelvic floor support, resulting in some degree of prolapse. Of these 10-20% will seek medical help. About 10% of all women will at one point in life undergo surgery for a prolapse condition. The incidence of POP requiring surgery after a hysterectomy is 3.6% per 1,000 women per year in the UK.
