Introduction and hypothesis Vaginal bulging is considered the key symptom for genital organ prolapse. The aim was to investigate the age-related prevalence and frequency of symptomatic pelvic organ prolapse (sPOP) and other pelvic floor symptoms in nonpregnant nullipara aged 25–64 years.

Women with sPOP were younger ( p
