T01-O-09 In vivo measurement of the human G-spot - 27/06/08
Résumé |
The purpose of this study was to use ultrasonography to evaluate the anatomical variability of the urethrovaginal space (G-spot) in women with and without vaginal orgasm.
20 healthy, neurologically intact volunteers were recruited. All women underwent a complete urodynamic evaluation and those with clinical and urodynamic urinary incontinence, idiopathic detrusor overactivity, or micturition disorders, as well as post-menopausal women and those with sexual dysfunction were excluded. The reported experience of vaginal orgasm with or without orgasmic ejaculation was investigated. 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.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 / female ejaculation was found, with the best correlation observed for the distal segment (r=0.863; p<0.0001). Inter-observer agreement between the designated evaluators was excellent (r= 0.87; p<0.001). 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 G spot, which can be correlated to the ability to experience the vaginal orgasm.
