Introduction Women’s sexual pain disorders include dyspareunia and vaginismus and there is need for state-of-the-art information in this area. Aim To update the scientific evidence published in 2004, from the 2nd International Consultation on Sexual Medicine pertaining to the diagnosis and treatment of women’s sexual pain disorders. Methods An expert committee, invited from six countries by the 3rd International Consultation, was comprised of eight researchers and clinicians from biological and social science disciplines, for the purpose of reviewing and grading the scientific evidence on nosology, etiology, diagnosis, and treatment of women’s sexual pain disorders. Main Outcome Measure Expert opinion was based on grading of evidence-based medical literature, extensive internal committee discussion, public presentation, and debate. Results A comprehensive assessment of medical, sexual, and psychosocial history is recommended for diagnosis and management. Indications for general and focused pelvic genital examination are identified. Evidence-based recommendations for assessment of women’s sexual pain disorders are reviewed. An evidence-based approach to management of these disorders is provided. Conclusions Continued efforts are warranted to conduct research and scientific reporting on the optimal assessment and management of women’s sexual pain disorders, including multidisciplinary approaches.

Women with vulvar vestibulitis syndrome (VVS) suffer from severe pain and discomfort in the area around the introitus at almost any stimulus that causes pressure within the vestibule. In spite of the severe sensory symptoms present in these women, the influence of the peripheral nerves in the vulvar vestibulum has not been clarified before. In this study the nerve supply in the vestibular mucosa in women with VVS and in healthy women free from vulvar symptoms has been revealed by PGP 9.5 immunohistochemistry. The results show a significant increase in the number of intraepithelial nerve endings in women with VVS, indicating an alteration in the nerve supply in the afflicted area.

Vulvar vestibulitis syndrome (VVS) is a long lasting disorder of superficial dyspareunia in young women. Quantitative sensory testing, including mechanical and temperature pain thresholds and warm/cold difference limen (WCL), was performed in the vestibular mucosa in 22 women (mean age 25.0 years) with vestibulitis and 20 control subjects (mean age 25.6 years). The tests were carried out on days 7-11 of the menstrual cycle. Patients had allodynia to mechanical testing with von Frey filaments, 14.3+/-3.1mN in the symptomatic posterior area as compared with 158+/-33.5mN in healthy subjects, P<0.0001. The pain threshold to heat was 38.6+/-0.6 degrees C in patients and 43.8+/-0.8 degrees C in controls, P<0.0001. In addition, pain threshold to cold was 21.6+/-1.2 degrees C in patients whereas cooling down to 6 degrees C was usually not painful in controls. WCL was 4.9+/-0.5 degrees C in patients and 9.6+/-1.5 degrees C in healthy subjects, P<0.01. The results are compatible with the hypothesis that patients with VVS have an increased innervation and/or sensitization of thermoreceptors and nociceptors in their vestibular mucosa.
