Abstract
Background Dyspareunia and restriction of sexual activity are often reported by patients with chronic pelvic pain, but less is known about which conditions or factors contribute most to these symptoms. Methods This is a cross-sectional study of consecutive new patients who presented to a chronic pelvic pain and endometriosis referral clinic between January 2013 and December 2015. Patients completed a detailed questionnaire prior to their first visit and underwent a comprehensive standardised pelvic examination at their first visit. Patients were grouped according to description of sexual activity as 'normal activity without pain', 'normal activity but painful', 'severely restricted by pain', or 'absent due to pain.' Primary outcome was restriction of sexual activity due to pain. Multinomial logistic regression was performed with 'normal activity without pain' group as reference category and adjusted for age, depression, history of endometriosis, and pelvic myofascial pain. Results Over half of the 187 patients with chronic pelvic pain described severely restricted (n =75, 40.1%) or absent (n =21, 11.2%) sexual activity due to pain. Pelvic myofascial pain was highly prevalent in this population and pelvic myofascial tenderness score was associated with higher odds of sexual activity that was severely restricted by pain (OR 1.05, 95% CI 1.01-1.09, P =0.006) or absent due to pain (OR 1.09, 95% CI 1.04-1.13, P Conclusion Dyspareunia and sexual dysfunction are highly prevalent among patients with chronic pelvic pain, and pelvic myofascial pain is strongly associated with restriction of sexual activity due to pain.
