The authors write of a “urethrovaginal space”, but this term is incorrect from a scientific point of view, and it’s not used in anatomy.

The authors write “The urethrovaginal space (where the Halban’s fascia runs) seems critical, being constituted of fibro-connective tissue and …”, but the anterior vaginal wall is separated from posterior urethral wall by the urethro-vaginal septum, and the anatomy of these structures is always described in anatomy textbooks. The size of urethro-vaginal septum is variable (5-12 mm) and the size of the muscular fibers present in the anterior vaginal wall and in the posterior urethral wall are variable. One “vaginal” orgasm at least once in the past month (in women that reported at least two acts of sexual intercourse per week…) it is not a significative difference with women without “vaginal” orgasm. Besides the authors write “By vaginal orgasm we mean the orgasm experienced after direct stimulation of the anterior vaginal wall by penetration”: but the authors do not write what was the position of coitus and how many women had masturbation.

The authors write of Grafenberg and of G-spot, but Grafenberg in 1950, hasn’t discovered any G-spot. Sexologists and people who believe in a “vaginal spot” should not use Grafenberg’s name yet.

The authors write “human clitoris-urethrovaginal complex, also known as the G-spot”, but this definition is incorrect: the G-spot (that currently is only an hypothesis) of Ladas, Whipple, and Perry is the Skene’s glands (i.e. female prostate, that is not embryological remnant).

The authors write “The close physical proximity of the urethra and the clitoris to the anterior vaginal wall suggests an association between these anatomical structures and sexual function” and “The presence of pseudocavernous tissue (clitoral bulb) in the anterior vaginal mucosa is a frequent but not universal finding (86%)”, but there’s no part of the vaginal wall adhereing to the clitoris, in the anterior vaginal mucosa there isn’t a pseudocavernous tissue and the bulbs don’t develop from the phallus, they don’t belong to the clitoris: the term clitoral bulb isn’t used in anatomy.
Urethrovaginal space, clitoral bulb, human clitoris-urethrovaginal complex, periurethral glans, G-spot, they are not terms used in anatomy.

The measurement by ultrasonography of the “space” within the anterior vaginal wall (that has no function in female sexuality, and what would be the normal measures of this “space”?…) is incorrect from a scientific point of view. Gravina et al.’s article increases the confusion on this topic (i.e. female orgasm) in sexologists and in women.
From sexologists it’s important to spread people scientific notions and the use of a correct scientific terminology describing female sexual anatomy and physiology.
