Measurement of the Thickness of the Urethrovaginal Space in Women with or without Vaginal Orgasm

Abstract

Introduction. The physiology and anatomy of female sexual function are poorly understood. The differences in sexual function among women may be partly attributed to anatomical factors. Aim. The purpose of this study was to use ultrasonography to evaluate the anatomical variability of the urethrovaginal space in women with and without vaginal orgasm. Methods. Twenty healthy, neurologically intact volunteers were recruited from a population of women who were a part of a previous published study. All women underwent a complete urodynamic evaluation and those with clinical and urodynamic urinary incontinence, idiopathic detrusor overactivity, or micturition disorders, as well as postmenopausal women and those with sexual dysfunction were excluded. The reported experience of vaginal orgasm was investigated. Main Outcome Measure. The urethrovaginal space thickness as measured by ultrasound was chosen as the indicator of urogenital anatomical variability. Designated evaluators carried out the measurements in a blinded fashion. Results. The urethrovaginal space and distal, middle, and proximal urethrovaginal segments were thinner in women without vaginal orgasm. A direct correlation between the presence of vaginal orgasm and the thickness of urethrovaginal space was found. Women with a thicker urethrovaginal space were more likely to experience vaginal orgasm (r = 0.884; P = 0.015). A direct and significant correlation between the thickness of each urethrovaginal segment and the presence of vaginal orgasm was found, with the best correlation observed for the distal segment (r = 0.863; P < 0.0001). Interobserver agreement between the designated evaluators was excellent (r = 0.87; P < 0.001). Conclusions. The measurement of the space within the anterior vaginal wall by ultrasonography is a simple tool to explore anatomical variability of the human clitoris-urethrovaginal complex, also known as the G-spot, which can be correlated to the ability to experience the vaginally activated orgasm.

Les explorations physiologiques de la réponse sexuelle chez la femme

“…Battaglia et al (2010), Buisson et al (2008), Foldès et Buisson (2009), Gravina et al (2008) sont autant d'auteurs qui ont contribué à l'avancement de nos connaissances sur l'anatomie fonctionnelle et tridimensionnelle du clitoris. Ces études ont montré que le clitoris ne se limitait pas à son gland, mais comportait un corps (coude), des tissus ischiocaverneux qui se prolongent (comme chez l'homme) en piliers (crura) latéraux, et des tissus bulbospongieux qui longent la vulve, entre le complexe urétral et vaginal.…”

Le point G ou l’absence de médecine sexuelle féminine

“…L'orgasme vaginal étant défini comme un orgasme survenant lors de la pénétration sans stimulation concomitante du clitoris externe. Bien que la série de cas soit petite, et que la cause de cette variation demeure peu claire, une différence anatomique marquant deux types d'orgasme a été scientifiquement prouvée [11]. En 2007, Wimpissinger et al décrivent en échographie une structure pouvant correspondre à une prostate féminine mais il semble y avoir eu une confusion avec l'échogénicité du sphincter externe de l'urètre [12].…”
