Statua che rappresenta l'eiaculazione femminile da un antico tempio Hindu situato in Karnataka, India, c. 1200 C.E.

Lo Squirting (letteralmente Spruzzare) si riferisce all'espulsione di una notevole quantità di liquido chiaro, o di una piccola quantità di liquido bianco e denso, sempre dall'uretra. Esso avviene durante l'orgasmo oppure nelle immediate vicinanze.

L'eiaculazione femminile è quasi sempre raggiunta tramite la stimolazione del Punto G, posto sulla parete anteriore della vagina.

[modifica] La natura dell'ejaculazione femminile

L'ejaculazione femminile non è un concetto nuovo. Il filosofo greco Aristotele ha notato la sua esistenza, Galen (secondo secolo) ha descritto la prostata femminile, l'anatomista italiano Renaldus Columbus fece riferimento all'ejaculazione femminile mentre spiegava il funzionamento della clitoride e nel 17esimo secolo, l'anatomista olandese Regnier de Graaf scrisse un libro sull'anatomia femminile parlando di "rushing out" e "coming in one gush" di fluidi femminili durante l'eccitazione sessuale. ^[1]

Poi fino agli anni 80 l'ejaculazione femminile è stata largamente ignorata dalla comunità medica. L'argomento è riemerso con la pubblicazione del libro best seller "The G-Spot" dei dottori Ladas, Whipple e Perry. Il libro non solo conferma la validità del Punto G ma brought female ejaculation to the forefront of women's sexual health inside the medical community.

While many in the medical and scientific communities are now acknowledging the existence of female ejaculation, there remains a large void when it comes to solid scientific data explaining the process of ejaculation in females or the source of the fluid itself.

Studies have been done by Dr. Beverly Whipple, Dr. John Perry, Dr. Gary Schuback, Dr. Milan Zaviacic and Dr. Cabello Santamaria but their findings are limited. While current information offers no solid information about the source of the fluid, chemical analysis performed on the fluid by a number of teams has revealed that it is not urine (the levels of creatinine and urea are too low).

[modifica] Ricerca

Parecchi studi sono stati realizzati sul liquido espulso durante l'eiaculazione femminile per determinarne la composizione chimica. Attraverso le analisi chimiche, è stato rilevato che il liquido in questione contiene:

glucosio (uno zucchero naturale) e fruttosio (un altro zucchero naturale, che può essre trovato anche nel liquido prostatico dello sperma)
antigene prostatico specifico (PSA), il liquido prodotto dagli uomini che serve a mantenere fluido il seme dopo l'eiaculazione, prodotto dalla prostata, mentre nelle donne si crede sia prodotto dalle ghiandole di Skene.
bassissime quantità di creatina ed urea (le due principali chemical markers dell'urina, trovabili in alte quantità dalle analisi delle urine appena prima e appena dopo l'eiaculazione.^[2]

In 1997 Dr. F Cabello Santamaria analyzed urine for PSA using Microparticle Enzyme Immunoassy and found that 75 percent of the samples showed a concentration of PSA in post-orgasmic urine samples which was not present in pre-orgasmic urine samples. The fluid collected at the point of orgasm (distinct from the urine samples) showed the presence of PSA in 100 percent of samples.^[3]

In 2002, Emanuele Jannini of L'Aquila University in Italy offered one explanation for this phenomenon, as well as for the frequent denials of its existence:

Skene's gland openings are usually the size of pinholes, and vary in size from one woman to another, to the point where they appear to be missing entirely in some women. If Skene's glands are the cause of female ejaculation, this may explain the observed absence of this phenomenon in many women.

Retrograde ejaculation, where the fluid travels up the urethra towards the bladder could also possibly account for the absence otherwise observed.

[modifica] The 'female prostate' and female ejaculation

Women do not have an exact equivalent of the male prostate gland, an essential part of the male reproductive system. They do, however, have structures which are homologous to the male prostate, this meaning that they have developed from the same embryonic tissue. (The testicles of the male and the ovaries of the female are also homologous.) These are called para-urethral glands or Skene’s glands – although the term ‘Skene’s glands’ is often reserved for the two para-urethral glands closest to the opening of the urethra. They are there because, for the first weeks in development, the male and female embryo are not yet differentiated.

The size and structure of the para-urethral glands varies, it seems relatively considerably, from woman to woman. The fluid they produce is similar to that produced by the male prostate and, as in the male, passes into the urethra – and in some cases may pass into the vagina. The glands fill with fluid during sexual arousal and may be felt through the vaginal wall. The swelling of the tissue surrounding the urethra may be a combination of the glands filling with fluid and of the swelling of the woman’s erectile tissue, the corpus spongiosum, which latter, in the male, gives a man his erection. Swelling of the non-visible part of the clitoris will also be evident.

It is, it seems, the rhythmic contractions of pelvic muscle during orgasm which expel the accumulated fluid as at least one constituent of female ejaculation. The amount of fluid released can be considerable, through repeated filling and emptying of the glands during orgasm.^[4]

[modifica] Medical Contradictions

Misinformation about female ejaculation can lead to misdiagnosis of underlying medical conditions or wrong diagnosis where no medical condition exists.

Current studies verify that female ejaculate is expelled through the urethra yet many continue to believe that the fluid leaves the body through the vagina. Expulsion of copious amounts of fluid from the vagina is called profuse vaginal discharge and can have several different causes:

physiological discharge - an abundant amount of discharge with no underlying medical disorder;

infection or sexually transmitted disease - presents with typical symptoms including itch, odor and / or redness; or

a sexually transmitted infection such as Trichomonas Vaginalis which will often present without typical symptoms.^[5]

For this reason it is important that any female who experiences abnormal amounts of vaginal discharge undergo a physical examination to rule out underlying medical conditions.

In other cases women who may not be properly educated about female ejaculation will assume to be suffering from urinary stress incontinence and will seek medical intervention. Treatment for urinary stress incontinence will often involve the use of medications or surgery, both unnecessary and dangerous if the source of the fluid leakage is female ejaculation.

Prior to seeking medical intervention these women should try to determine whether the fluid is female ejaculate or urine.

[modifica] Female transsexual ejaculation

Female ejaculation in post-operative transsexual women has also been reported. The source of this fluid would most likely be the prostate gland, which is not removed during neovaginoplasty.Template:Fact

[modifica] Pornography

In some pornographic movies, women are shown ejaculating a clear or milky fluid. The validity of pornography as a source of evidence is, however, suspect, as there is a strong incentive to generate dramatic visual effects, with no implication or assurance of accurate recording of real events. Allegedly, some of this is done through trick editing or by filling the vagina with fluids from external sources; with the camera on, the woman can then expel the fluid. In other cases, the fluid is clearly seen as coming from her urethra, at high velocity. It is possible that urination is sometimes used in this context to provide the illusion of a female ejaculation.

Studies by Gwendolyn Kelly Boyer indicate that the white fluid may be semen from former sexual encounters that has not exited the vagina. According to her theory, the male who has sex with the female before she has a chance to dispel the semen from previous encounters, may cause strong enough contractions during orgasm to force the fluid through the vaginal opening. This does not occur in many women because some women are unable to achieve orgasm during regular intercourse.Template:Fact In addition, some women have been found to achieve ejaculation through stimulation without a sexual partner.

[modifica] Famous female ejaculators in adult film

In the pornographic film industry, Cytherea is generally acknowledged to be the "squirt queen", due to her particularly intense and voluminous ejaculations. Other famed ejaculators include Debi Diamond, Flower Tucci, Tianna Lynn, Dasha, Daphne Rosen, Fallon, Alisha Klass, Missy Monroe, Lily Thai, Nikki Charm, Annie Cruz, Nici Sterling, Sarah Jane Hamilton, and Ariana Jollee. Outside the realm of pornography, author and sexologist Carol Queen has produced an instructional video (starring herself) that purports to teach female ejaculation to women not previously able to achieve it. Sex Educator Dr. Susan Block has produced an instructional video called "Dr. Suzy's Squirt Salon" featuring G-Spot Female Ejaculation Expert Deborah Sundahl teaching her to squirt, as well as demonstrations from voluminous ejaculator Annie Body and Tantric ejaculatrix Leila Swan, and extreme close-up footage of the G-Spot before, after and during ejaculation.Template:Fact

[modifica] British film censorship

In the United Kingdom, the British Board of Film Classification denies the existence of the phenomenon of female ejaculation, regarding it instead as urination during sex, thus banning its depiction under its rules. These dictate the removal of anything that could be successfully prosecuted under Section 2 of the Obscene Publications Act, the current interpretation of which includes the depiction of urolagnia.[1]
