G-Spot Variations Affect Orgasmic Ability
Study finds that: “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.”

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.
