Physiology of female ejaculation-The science behind female ejaculation | The Independent

Their origins, quantity, compositions, and expulsion mechanisms depend on anatomical and pathophysiological dispositions and the degree of sexual arousal. These are natural sexual responses but may also represent symptoms of urinary incontinence. AIM: The study aims to clarify the etiology of fluid leakage at orgasm, distinguish between associated physiological sexual responses, and differentiate these phenomena from symptoms of illness. Both phenomena may occur simultaneously. CI is divided into penetration and orgasmic forms.

However, modern researchers have built upon the experiments of historically well-known sex researchers to explain the phenomenon known as female ejaculation.

  • A shared paradigm has been created that includes any fluid expulsion during sexual activities with the name of "female ejaculation.
  • Ejaculation , the release of sperm cells and seminal plasma from the male reproductive system.
  • The physiology of arousal in the male is elicited in numerous ways.

Fair warning, this article will make reference to squirting, gushing and the G-spot. Many of you may be surprised to learn that females are capable of ejaculation, however, the phenomena has been written about from as early as 4 Century China, where the liquids excreted during orgasm were believed to be imbued with mystical and healthful properties. As it turns out, during orgasm some women per cent experience the involuntary emission of fluid ranging from 30 to mL.

This has become known colloquially as squirting, though this usually refers to a larger amount of liquid being excreted. In , psychologist Havelock Ellis proposed that female ejaculation was analogous to semen and originated from the Bartholin glands two pea-sized glands responsible for secreting mucous which lubricates the vagina. This landmark study demonstrated a clear difference between the liquid excreted during orgasm and urine, a finding that was later confirmed by several independent scientific studies.

Yet the scientific community remains divided, some questioning the very existence of the G-spot while others question the vast differences in the amount of fluid expressed by women.

Some women report very little liquid mL resembling watered-down milk, while others express far greater volume. This has led some researchers to maintain that squirting is actually an involuntary emission of urine, or hyper lubrication. A recent study published out of Le Chesnay, France conducted by Samuel Salama and his colleagues sought to lay these questions to rest by combining ultra-sound imaging with chemical analysis of higher volume female ejaculate.

The researchers recruited seven women who self-reported that they squirted the equivalent to a glass of water during orgasm, enough to noticeably wet the bed-sheets. The women provided a urine sample, and then underwent an ultrasound that confirmed that their bladders were indeed empty. The women then, either with the help of their partner or alone, began sexual stimulation and once sufficiently aroused underwent a second ultrasound.

At this point, the women returned to the task at hand until they achieved orgasm and ejaculation. A sample of the ejaculate was collected and the final ultrasound performed. However, the second ultrasound, conducted when the women were close to orgasm, showed significant bladder filling. This suggested that female ejaculation, at least for these women, was largely urine. Biochemical analysis of the fluid showed that this was definitely the case for two of the women in the study.

Yes and no. However, there does appear to be evidence that a smaller volume of fluid is actually female prostate secretion due to mechanical stimulation of the G-spot. Further, it is unknown conclusively whether these two forms of excretion are mutually exclusive, or whether there is some overlap as suggested by the presence of PSA in the urine of women in this study.

Likely, women who are capable of ejaculation naturally vary in the amount of fluid they excrete. The implications for personal and sexual health are also unclear. An international survey of women who were capable of ejaculating found that four of five reported that squirting was enriching to their sexual lives. However, this included any volume of fluid emission.

The only clear conclusion that the researchers draw from this latest study is a recommendation to urinate frequently before and during sexual activity if squirting presents a problem. Other than that, stay hydrated and have fun.

Female ejaculation comes in two forms, scientists find | New Scientist

Female ejaculation is characterized as an expulsion of fluid from or near the vagina during or before an orgasm. It is also known colloquially as squirting or gushing , [1] although these are considered to be different phenomena in some research publications. There have been few studies on female ejaculation. The reasons for the interest in female ejaculation have been questioned by feminist writers. In the 16th century, the Dutch physician Laevinius Lemnius , referred to how a woman "draws forth the man's seed and casts her own with it".

In the 17th century, the Dutch anatomist Reinier de Graaf wrote an influential treatise on the reproductive organs Concerning the Generative Organs of Women which is much cited in the literature on this topic. De Graaf discussed the original controversy but supported the Aristotelian view. In the lower part, near the outlet of the urinary passage, this membrane is pierced by large ducts, or lacunae, through which pituito-serous matter occasionally discharges in considerable quantities.

Between this very thin membrane and the fleshy fibres we have just described there is, along the whole duct of the urethra, a whitish membranous substance about one finger-breadth thick which completely surrounds the urethral canal The substance could be called quite aptly the female 'prostatae' or 'corpus glandulosum', 'glandulous body' He identified [XIII] the various controversies regarding the ejaculate and its origin, but stated he believed that this fluid "which rushes out with such impetus during venereal combat or libidinous imagining" was derived from a number of sources, including the vagina, urinary tract, cervix and uterus.

He appears to identify Skene's ducts , when he writes [XIII: ] "those [ducts] which are visible around the orifice of the neck of the vagina and the outlet of the urinary passage receive their fluid from the female 'parastatae', or rather the thick membranous body around the urinary passage.

Krafft-Ebing's study of sexual perversion, Psychopathia Sexualis , describes female ejaculation under the heading "Congenital Sexual Inversion in Women" as a perversion related to neurasthenia and homosexuality. It is also described by Freud in pathological terms in his study of Dora , where he relates it to hysteria. The pride taken by women in the appearance of their genitals is quite a special feature of their vanity; and disorders of genitals which they think calculated to inspire feelings of repugnance or even disgust have an incredible power of humiliating them, of lowering their self-esteem, and of making them irritable, sensitive, and distrustful.

An abnormal secretion of the mucous membrane of the vagina is looked upon as source of disgust. Thus we find Almeda Sperry writing to Emma Goldman in , about the "rhythmic spurt of your love juices".

Certainly van de Velde was well aware of the varied experiences of women. It appears that the majority of laymen believe that something is forcibly squirted or propelled or extruded , or expelled from the woman's body in orgasm, and should so happen normally, as in the man's case. Finally it is just as certain that such an 'ejaculation' does not take place in many women of sexually normal functions, as that it does take place in others.

In , Huffman, an American gynaecologist, published his studies of the prostatic tissue in women together with a historical account and detailed drawings. The urethra might well be compared to a tree about which and growing outward from its base are numerous stunted branches, the paraurethral ducts and glands. An erotic zone always could be demonstrated on the anterior wall of the vagina along the course of the urethra In the course of sexual stimulation , the female urethra begins to enlarge and can be felt easily.

It swells out greatly at the end of orgasm Occasionally the production of fluids is If there is the opportunity to observe the orgasm of such women, one can see that large quantities of a clear transparent fluid are expelled not from the vulva, but out of the urethra in gushes. At first I thought that the bladder sphincter had become defective by the intensity 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. However this paper made little impact, and was dismissed in the major sexological writings of that time, such as Kinsey [30] and Masters and Johnson , [31] equating this "erroneous belief" with urinary stress incontinence. Although clearly Kinsey was familiar with the phenomenon, commenting that p.

Muscular contractions of the vagina following orgasm may squeeze out some of the genital secretions, and in a few cases eject them with some force. The topic did not receive serious attention again until a review by Josephine Lowndes Sevely and JW Bennett appeared in Whipple became aware of the phenomenon when studying urinary incontinence, with which it is often confused.

Nevertheless, the theory advanced by these authors was immediately dismissed by many other authors, such as physiologist Joseph Bohlen, [38] for not being based on rigorous scientific procedures, and psychiatrist Helen Singer Kaplan stated: [39]. Female ejaculation as distinct from female urination during orgasm has never been scientifically substantiated and is highly questionable, to say the least. Some radical feminist writers, such as Sheila Jeffreys were also dismissive, claiming it as a figment of male fantasy: [40].

There are examples in the sexological literature of men's sexual fantasies about lesbian sexuality. Krafft-Ebing invented a form of ejaculation for women. As she observes, the female perineal urethra is embedded in the anterior vaginal wall and is surrounded by erectile tissue in all directions except posteriorly where it relates to the vaginal wall.

These parts have a shared vasculature and nerve supply and during sexual stimulation respond as a unit". Malinowski states that in the language of the Trobriand Island people, a single word is used to describe ejaculation in both male and female.

Both the male and female discharge are called by the same name momona or momola , and they ascribe to both the same origin in the kidneys, and the same function, which has nothing to do with generation, but is concerned with lubricating the membrane and increasing pleasure. In describing sexual relations amongst the Trukese Micronesians, Gladwin and Sarason state that "Female orgasm is commonly signalled by urination". See also Chalker pp. Historically in Rwanda, the kunyaza sexual technique has the reputation of triggering female ejaculation kunyara.

The ancient sexual practice has been exercised for over years in east and central Africa. Amongst the Buganda tribe of Uganda, the sexual practice is called kachabali spraying the wall. For instance, much of the research into the nature of the fluid focuses on determining whether it is or contains urine.

Since the area of interest is para-urethral glands, it is impossible to completely separate the secretions from urine, especially considering that there may be retrograde ejaculation into the urethra towards the bladder.

Research has attempted to use chemicals that are excreted in the urine so that any urinary contamination can be detected. Further methodological issues include the fact that the composition of the fluid appears to vary with the menstrual cycle, [49] and that the biochemical profile of the para-urethral tissues varies with age. The key questions are the source of the fluid produced, and its composition. Some aspects of the research community distinguish between female ejaculation and what is colloquially known as squirting or gushing.

In these research publications, it is suggested that "real" female ejaculation is the release of a very scanty, thick, and whitish fluid from the female prostate, [2] while the "squirting" or "gushing" shown frequently in pornography is a different phenomenon: the expulsion of clear and abundant fluid, which has been shown to be a diluted fluid from the urinary bladder. Towards the later part of the 20th century, there was significant confusion between female ejaculation and coital incontinence.

In , Bohlen explained the accepted wisdom: [38]. The previously accepted notion that all fluid expelled during a woman's orgasm is urine is now being challenged Scientific studies from the s and later have demonstrated that the substance produced is distinct from urine, though it does show similarities such as alkalinity with urine. Seven women claiming to have ejaculations expelled large volumes of urine through the catheter at orgasm, and little to no other fluid. It may be important for physicians to establish whether there is in fact any incontinence in women who report ejaculation, to avoid unnecessary interventions.

In individual cases, the exact source of any reported discharge may not be obvious without further investigation. Critics have maintained that ejaculation is either stress incontinence or vaginal lubrication. Early work was contradictory; the initial study on one woman by Addiego and colleagues, reported in , [35] could not be confirmed in a subsequent study on 11 women in , [56] but was confirmed in another 7 women in A study on two women involved ultrasound , endoscopy , and biochemical analysis of fluid.

The ejaculate was compared to pre-orgasmic urine from the same woman, and also to published data on male ejaculate. In both women, higher levels of PSA, PAP, and glucose but lower levels of creatinine were found in the ejaculate than the urine. PSA levels were comparable to those in males.

Ultrasounds from a study, involving seven women who reported recurring massive fluid emission during sexual arousal, confirmed thorough bladder emptiness before stimulation, noticeable bladder filling before squirting and demonstrated that the bladder had again been emptied after squirting. Although small amounts of prostatic secretions are present in the emitted fluid, the study suggests that squirting is essentially the involuntary emission of urine during sexual activity. One very practical objection relates to the reported volumes ejaculated, since this fluid must be stored somewhere in the pelvis, of which the urinary bladder is the largest source.

The actual volume of the para-urethral tissue is quite small. By comparison, male ejaculate varies from 0. One approach is to use a chemical like methylene blue so that any urinary component can be detected. PAP and PSA have been identified in the para-urethral tissues, using biochemical and immunohistochemical methods, suggesting that the ejaculate is likely to arise from the ducts in these tissues, in a manner homologous to that in the male.

PSA occurs in urine, and is elevated in post-orgasmic samples compared to pre-orgasmic. Simultaneous collection of ejaculate also showed PSA in both urine and ejaculate in all cases, but in higher concentration in the ejaculate than in the urine. Sexual functions, and orgasm in particular, remain poorly understood scientifically, as opposed to politically and philosophically. The debate in the current literature focuses on three threads: the existence of female ejaculation, its source s and composition, and its relationship to theories of female sexuality.

There is some resistance from feminists to what has been perceived as a male lens in interpreting the data and construct. These tissues, surrounding the distal urethra, and anterior to the vagina, have a common embryological origin to the prostatic tissue in the male. In an extensive survey, Darling and colleagues claim support for the existence of ejaculation, [11] while in a sharply critical response, Alzate [58] [75] states that direct experimentation fails to provide any evidence.

Shannon Bell argues that the debate is confused by the discussion of two separate phenomena. Bell's critique lies at the heart of feminist concerns about this debate, namely a tendency to "disregard, reinterpret, and overwrite women's subjective descriptions. Importantly, a number of the women stated that they had been diagnosed with urinary incontinence. The book by Ladas, Whipple, and Perry. The continuing debate is further illustrated in the angry exchange of letters between the author and researchers in the American Journal of Obstetrics and Gynaecology in following the publication of 'The G-spot: A modern gynecological myth' by Terrence Hines.

The terminology such as female prostate and female ejaculation invoke images of the female as merely an imitation of the male, mapping the female body onto the male, as if, like the Galenic view, it was incomplete. Others argue it should be retained as a distinctive feminine characteristic distinguishable from the male, and imbued with different properties and purpose.

Many women, before learning about ejaculation, experienced shame or avoided sexual intimacy under the belief that they had wet the bed. Contemporary women's health literature summarises what is considered factual as being that the amount of fluid varies greatly and may be unnoticeable, occurs with or without vaginal stimulation , and may accompany orgasm or merely intense sexual pleasure, and orgasm may occur without ejaculation.

Whether it can be learned or not, women report that they can induce it by enhancing their sexual response.

Sundahl describes it as a birthright and essential part of female creativity. The presence of chemical markers such as PSA or PAP in the female genital tract has been considered evidence in rape trials, [87] but Sensabaugh and Kahane demonstrated in four specimens that PAP was an order of magnitude greater in a woman's ejaculate than in her urine.

Recently, knowledge that these markers can be of female origin has led to acquittal based on forensic evidence. Sarah Jane Hamilton became known as one of the first alleged female ejaculators from Britain, [] though this was later dismissed by porn reviewer Pat Riley as urination in his review of The British are Coming However, she has commented that she could not ejaculate on cue even though producers expect her to like a male performer.
