Abstract

OBJECTIVE: This scoping review aims to evaluate recent studies that examine the relationship between dyspareunia and neurophysiologic factors, and to synthesize their results as it pertains to the development and treatment of introital/vulvar dyspareunia and deep dyspareunia DATA SOURCES: A comprehensive search was conducted in PubMed (NLM), Embase (Elsevier), CINAHL (EBSCOhost), Web of Science (Clarivate), Psycinfo (ProQuest), and Cochrane Library (Wiley) to find peer reviewed studies written in English published in 2000 or later that discussed how neurophysiology is related to dyspareunia. Search terms: dyspareunia; painful intercourse; genito-pelvic pain; penetration disorder; neuropsychology; central nervous system sensitization; neur; central sensitization. METHODS OF STUDY SELECTION: A total of 1101 studies were screened and 108 were included in the review. Abstract and full text screening were performed by 4 authors. Articles were also excluded if they did not include an objective diagnostic tool or objective treatment outcome of dyspareunia. We included original peer-reviewed published research in the form of randomized control trials, cohort studies, case control studies, case series of greater than 20 participants, and systematic reviews. INTEGRATION AND RESULTS: Multiple study types were noted: 22 randomized control trials, 9 prospective cohort studies, 3 retrospective cohort studies, 30 case control, 16 case series, 17 cross-sectional, and 11 systematic reviews. Of these articles, 72 focused on introital/superficial dyspareunia, 23 focused on deep dyspareunia, and 13 on both. Data was synthesized in text and table format, separated by type of dyspareunia (introital vs deep) and either etiology/diagnosis or treatment. CONCLUSION: There are complex neurophysiologic mechanisms that influence both introital and deep dyspareunia, highlighting the roles of peripheral and central sensitization, nerve fiber density, and neuroplasticity in this condition. There are several promising treatments, including TENS, botulinum toxin A, physical therapy, and various multimodal approaches; but further research is needed to establish standardized therapeutic guidelines.
