INTRODUCTION: Diagnosis and treatment of female sexual dysfunction (FSD) are currently based on subjective female reports and physical examination. The GenitoSensory Analyzer (GSA) is a quantitative sensory testing tool designed to quantify vibratory and thermal sensation in the vagina and clitoris in a reproducible manner, and may therefore contribute to the diagnosis and management of FSD. AIM: To address the question of whether women with arousal and/or orgasmic sexual disorders have genital sensory abnormalities as measured by the GSA. MAIN OUTCOME MEASURES: Thresholds for warm, cold, and vibratory sensation at predetermined points in the vaginal wall and clitoris. METHODS: Female subjects complaining of arousal and/or orgasmic sexual disorders for more than 6 months were evaluated using a questionnaire based on the female sexual function index (FSFI). Women with a desire disorder, pain disorder, vulvar vestibulitis syndrome, or acute vaginal or/and introital infection were excluded. The GSA device measured thresholds for warm, cold, and vibratory sensation at predetermined points in the vaginal wall and clitoris. Eight measurements were obtained, and deviations from previously published normative values were identified. RESULTS: Twenty-eight women (age 40.4 +/- 13 years) complaining of arousal and/or orgasmic FSD comprised the study cohort. Twenty-five of them (89%) had at least one pathologic genitor-sensory threshold on GSA testing and 19 (68%) had >3 pathologic thresholds. Pathologic GSA results were associated with lower arousal scores on the FSFI questionnaire, older age, and menopausal status. CONCLUSIONS: Most of the study women had at least one genitor-sensory pathology on GSA testing, indicating a possible organic component in their disorder. Our findings support the incorporation of the GSA as a quantitative tool in the assessment and diagnosis of patients with FSD.
