Wimpissinger et al.  wrote: ‘Female ejaculation is defined as an emission of fluid during orgasm [Gräfenberg 1950; Darling et al. 1990] … According to the definition used in the present study, all of the women who participated in the online survey were able to ejaculate … As female ejaculation could not be clinically proven in the participants of the study, the terminology of “perceived female ejaculation” was used where applicable’.
The 1950 article by Gräfenberg  the term ‘female ejaculation’ does not appear. Gräfenberg reported: ‘Sometimes the mucus is produced so abundantly and makes the vulva slippery that the female partner is inclined to compare it with the ejaculation of the male. Occasionally the production of fluids is so profuse that a large towel has to be spread under the woman to prevent the bedsheets getting soiled. This convulsory expulsion of fluids occurs always at the acme of the orgasm … Involuntary expulsion of urine is reported in sex literature. In the cases observed by us, the fluid was examined and it had no urinary character. I am inclined to believe that “urine” reported to be expelled during female orgasm is not urine, but only secretions of the intraurethral glands correlated with the erotogenic zone along the urethra in the anterior vaginal wall’.
Besides if female ejaculation is defined as an emission of fluid only during orgasm, why have Wimpissinger et al. written in the Online Questionnaire ‘Female ejaculation – in the context of this study – denotes fluid expulsions during intercourse or at orgasm'? In addition, Wimpissinger et al.  wrote ‘The instrument used to obtain data – an online survey of healthy women experiencing ejaculation – was a strength as well as a limitation of the study’.
Wimpissinger et al.  wrote ‘The concept of vaginal versus clitoral orgasm has not been scientifically established’.
The female vagina has little sensitivity and the vaginal orgasm does not have any scientific basis: the vaginal orgasm does not exist [3, 4].
Wimpissinger et al. wrote  ‘This finding adds to the discussion concerning the anterior vaginal wall and the possible role of urethrovaginal thickness in female sexual function [Jannini et al. 2010; Gravina et al. 2008]. There has been no indication of the fact that the stimulation of a presumed G-spot was an exclusive trigger for ejaculation’.
Gravina et al.  in 2008 wrote ‘The urethrovaginal space (where the Halban's fascia runs) seems critical, being constituted of fibroconnective tissue and large numbers of blood vessels, glands, muscular fibers, and nerve endings’.
Puppo  in 2012 wrote ‘Urethrovaginal space is an incorrect term from a scientific point of view; the anterior vaginal wall is separated from the posterior urethral wall by the urethrovaginal septum. In addition, Halban's fascia, a layer of dense connective situated in the bladder-vaginal septum, does not correspond to the male corpus spongiosum as some sexologists believe: this assumption has no embryological and anatomical support’. Besides, Gravina et al.  reported that they made an echography of the G-spot, but in their article there is no picture that shows a G-spot!
The G-spot has become the centre of a multimillion dollar business. All published scientific data indicates that the G-spot does not exist. The supposed G-spot should not be linked with Gräfenberg's name and the G-spot amplification is an unnecessary and inefficacious medical procedure [3, 4, 6-8].
In the vaginal vestibule, the external orifice of the urethra with the paraurethral (Skene's) ducts opening on both sides is seen. Their length is 0.5–3 cm and they are found, in women, with the intraurethral (Skene's) glands considered by some as the ‘female prostate’. The secretion of these glands is expelled through the urethral meatus or through the orifices of the paraurethral ducts into the vaginal vestibule, which corresponds to the dorsal wall of the male cavernosa urethra (while the labia minora correspond to the ventral wall) [3, 7].
Another misused term that is claimed to have originated from Gräfenberg's 1950 article is ‘female ejaculation’ . Studies by Shafik et al.  revealed ‘Opinions vary over whether female ejaculation exists or not. We investigated the hypothesis that female orgasm is not associated with ejaculation. Thirty-eight healthy women were studied. The female orgasm was not associated with the appearance of fluid coming out of the vagina or urethra’.
Wimpissinger et al.  wrote ‘Fluid emission usually occurs during orgasm’. From a physiological point of view the term ‘female emission’ is more accurate than female ejaculation (in a few women there is a powerful expulsion of this fluid); female prostate secretion during orgasm corresponds to the emission phase of male ejaculation (i.e. the emission of seminal liquid that is ejected out in the prostatic urethra). The lack of the ejaculation phase in the female could explain why women do not have a refractory period and are able to have multiple orgasms [3, 7].
Clitoral/vaginal/uterine orgasm, G- /A- /C- /U- /K- /O- /DVZ-spot orgasm, female ejaculation, G-spot amplification, persistent genital arousal disorder, clitoral bulbs, clitoral or clitoris-urethra-vaginal complex, internal clitoris, periurethral glans, urethrovaginal space, genitosensory component of the vagus nerve, are terms that must not be used by gynaecologists, sexologists, sexual medicine experts, women and the mass-media. The claims that were made in numerous articles that have been written by Addiego, Whipple, Perry, Jannini, Buisson, O'Connell, Brody, Ostrzenski, and others, have no scientific basis [3, 7, 8].
The use of such unscientifically based terms by researchers and scientists serves as the fuel for the evolution of myths, which are then amplified by mass-media and become popular and well accepted ones. Some medical professionals take advantage of these myths and of the expectations (or the distress) of women influenced by the myth for their own personal benefit. I warn colleagues to maintain a high level of professionalism and not to be tempted by non-medical considerations .
