Mean nerve fiber immunofluorescence intensity was 150.3\u2009\u00b1\u200912.5 SD in the patient group compared to 139.3\u2009\u00b1\u20098.5 SD in the control group (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01).

At logistic regression analysis, nerve fiber immunofluorescence intensity showed no significant correlation to age, menopausal age, parity, body mass index (BMI), prolapse quantification, or any specific self\u2010reported anorectal symptom. Increased nerve fiber immunofluorescence intensity was correlated to increased perineal descent (OR 1.3, 95% CI 1.1\u20132.1) although not to the size of the rectocele (OR 0.5, 95% CI 0.9\u20131.2).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results show that rectocele may be associated with increased rectovaginal innervation, suggestive of reinnervation of the rectovaginal wall. Nerve fiber density correlated poorly with findings at clinical and radiological examination.
