Department of Psychology, McGill University, Montreal, Quebec, Canada.Journal of Sex and Marital Therapy (Impact Factor: 1.27). 03/2012; 38(2):128-50. DOI: 10.1080/0092623X.2011.569641
This study investigated the clinical attributes of postmenopausal dyspareunia. The authors obtained a systematic description of pain symptomatology from 182 postmenopausal dyspareunia sufferers using a structured interview, quantitative sensory testing, a standardized pain measure, and gynecological examination. The authors conducted a cluster analysis to examine whether sufferers could be categorized using clinical pain and gynecological factors. The authors delineated 6 subgroups, each exhibiting distinct combinations of pain and gynecological characteristics. The results support the hypothesis that, similarly to premenopausal dyspareunia, postmenopausal dyspareunia is a heterogeneous condition.

ABSTRACT: Introduction. Although dyspareunia experienced after menopause is widely attributed to declining estrogen levels and vulvovaginal atrophy, critical reviews of the literature have suggested that these factors are incomplete as explanatory mechanisms. Little is known about psychosocial factors that may also be implicated in postmenopausal dyspareunic pain. Aim. To determine the extent to which levels of estrogens and progesterone, vulvovaginal atrophy, cognitive-emotional factors, and dyadic adjustment are predictive of postmenopausal dyspareunic pain intensity. Methods. A total of 182 postmenopausal dyspareunia sufferers underwent a structured interview concerning sociodemographic status as well as medical and pain histories, gynecological examination, cytological evaluation, a blood draw, and answered a series of self-report questionnaires. Given the large number of genital and pelvic pain variables measured, a principal components analysis was undertaken to identify a smaller number of components representing meaningful dimensions of genital and pelvic pain. Main Outcome Measures. Pain severity ratings during intercourse were obtained using the McGill Pain Questionnaire. Pain ratings were also obtained during gynecological assessment. Serum estrone, estradiol, and progesterone levels were measured via immunoassay. The Vaginal Atrophy Index and maturation value were used to determine vulvovaginal atrophy severity. Participants completed the Pain Catastrophizing Scale, State-Trait Anxiety Inventory, The Beck Depression Inventory-II, and Dyadic Adjustment Scale. Results. Hormone levels were not found to be consistent predictors of pain severity. Maturation value and cognitive-emotional variables (e.g., catastrophization, depression, anxiety) were significant predictors of vestibular pain, which affected over 90% of our sample. Relationship adjustment variables were inversely associated with pain severity within several genital locations. Conclusions. Results suggest that the traditional hypoestrogen and vulvovaginal atrophy conceptualization of postmenopausal dyspareunia is an insufficient explanatory model, and that pain is also influenced by cognitive, affective, and dyadic factors.

ABSTRACT: To assess whether premenopausal and postmenopausal vestibulodynia have different histologic features. We conducted a retrospective analysis of vestibulectomy specimens from 21 women with postmenopausal vestibulodynia and compared them with 88 premenopausal patients (42 primary, 46 secondary). Women with primary vestibulodynia experienced pain at first introital touch and women with secondary vestibulodynia experienced pain after an interval of painless intercourse. Clinical records established the type of vestibulodynia, duration of symptoms, and hormone status. Tissues were stained for inflammation, nerves, mast cells, estrogen receptor α, and progesterone receptor. Histologic findings in the postmenopausal patients were compared with primary and secondary premenopausal patients using proportional odds logistic regression and analysis of variance. Seventy-one percent (15/21) of postmenopausal women reported vestibular dyspareunia related to a drop in estrogen either with menopause (13/21) or previously, postpartum (2/21). Eighty-six percent (18/21) of postmenopausal patients were using local or systemic estrogen but pain persisted. Compared with premenopausal primary and secondary vestibular biopsies, postmenopausal tissues had more lymphocytes (unadjusted odds ratio [OR] 9.0, 95% confidence interval [CI] 2.8-33.3; adjusted OR for parity and duration of symptoms 9.1, 95% CI 2.6-31.9; unadjusted OR 6.2, 95% CI 1.9-20.0; adjusted OR 6.6, 95% CI 2.0-21.9, respectively) and mast cells (mean 36 compared with 28 and 36 compared with 26, respectively). There was significantly less neural hyperplasia and progesterone receptor expression in postmenopausal biopsies compared with primary cases but less progesterone receptor and similar neural hyperplasia compared with premenopausal secondary cases. Estrogen receptor α did not vary among groups. Premenopausal and postmenopausal vestibulodynia share histologic features of neurogenic inflammation but differ strikingly in degree. When estrogen supplement does not alleviate symptoms of postmenopausal dyspareunia, vestibulodynia should be considered. LEVEL OF EVIDENCE:: II.Obstetrics and Gynecology 10/2013; 122(4):787-793.

ABSTRACT: To locate sites of genital tenderness in breast cancer survivors not using estrogen who experience dyspareunia and to test the hypothesis that tenderness is limited to the vulvar vestibule rather than the vagina and is reversed by topical anesthetic. Postmenopausal survivors of breast cancer with moderate and severe dyspareunia were recruited for an examination including randomization to a double-blind intervention using topical aqueous 4% lidocaine or normal saline for 3 minutes to the areas found to be tender. Comparisons of changes in patients' reported numerical rating scale values were made with the Wilcoxon rank-sum test with significance set at P<.05. Forty-nine patients aged 37-69 years (mean 55.6±8.6 years) had a median coital pain score of 8 (interquartile range 7-9, scale 0-10). On examination, all women had tenderness in the vulvar vestibule (worst site 4 o'clock median 6, 4-7). In addition, one had significant vaginal mucosal tenderness and two had pelvic floor myalgia. All had vulvovaginal atrophy with 86% having no intravaginal discharge. Aqueous lidocaine 4% reduced the vestibular tenderness of all painful sites. For example, pain at the worst site changed from a median of 5 (4-7) to 0 (0-1) as compared with saline placebo, which changed the worst site score from 6 (4-7) to 4 (3-6) (P<.001). After lidocaine application, speculum placement was nontender in the 47 without either myalgia or vaginal mucosal tenderness. In breast cancer survivors with dyspareunia, exquisite sensitivity was vestibular and reversible with aqueous lidocaine. Vaginal tenderness was rare despite severe atrophy.
