About 316 million women suffer from genital prolapse worldwide. Based solely on patient symptoms, the prevalence of pelvic organ prolapse (POP) is 3–6%; however, it rises up to 50% if based on clinical examination because most of the mild cases are asymptomatic. According to the Women's Health Initiative (WHI) in the United States, 40% of women have some degree of POP with 14% having uterine prolapse. The incidence of POP surgery varies from 1.5–1.8 per 1000‐woman years with peak age at 60–69. The probability of having a surgical correction for POP by age 80 is estimated to be one in five.

Based on the WHI data, incidence of stage 1–3 prolapse is estimated to be 9.3 per 100 woman‐years for cystocele, 5.7 per 100 woman‐years for rectocele, and 1.5 per100 woman‐years for uterine prolapse. Prolapse progression ranged from 1.9% for uterine prolapse, to 9.5% for cystocele, and 14% for rectocele. Older, parous women are more likely to develop new or progressive prolapse.

In the United States, POP is thought to be the leading cause of more than 300 000 surgical procedures per year with 25% undergoing reoperations at a total cost of more than one billion dollars annually. The estimated direct annual cost of ambulatory care utilisation for pelvic floor disorders during a nine‐year period (1996–2005) increased by 40% and, if extrapolated to POP surgery, the total annual cost would be over 1.4 billion.
