Reports

In questionnaire surveys, 35–50% of women report that they have at some time experienced the gushing of fluid during orgasm. Other studies find anywhere from 10–69%, depending on the definitions and methods used. For instance Kratochvíl (1994) surveyed 200 women and found that 6% reported ejaculating, an additional 13% had some experience and about 60% reported release of fluid without actual gushing. Reports on the volume of fluid expelled vary considerably from amounts that would be imperceptible to a woman, to mean values of 1–5 ml, although volumes as high as one pint (473 ml) have been reported.

 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.
He identified the source as the glandular structures and ducts surrounding the urethra.
He identified [XIII:212] 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: 213] "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." However he appears not to distinguish between the lubrication of the perineum during arousal and an orgasmic ejaculate when he refers to liquid "which in libidinous women often rushes out at the mere sight of a handsome man." Further on [XIII:214] he refers to "liquid as usually comes from the pudenda in one gush." However, his prime purpose was to distinguish between generative fluid and pleasurable fluid, in his stand on the Aristotelian semen controversy.

 (1926). Certainly van de Velde was well aware of the varied experiences of women.
Yet the subject was largely ignored for most of the early part of the century. In 1948, Huffman, an American gynaecologist, published his studies of the prostatic tissue in women together with an historical account and detailed drawings. These clearly showed the difference between the original glands identified by Skene at the urinary meatus, and the more proximal collections of glandular tissue emptying directly into the urethra.
To date most of the interest had focussed on the substance and structure rather than function of the glands. A more definitive contemporary account of ejaculation appeared shortly after, in 1950, with the publication of an essay by Gräfenberg

(emphasis in original) yet dismissed it (p. 135) – "female ejaculation is an erroneous but widespread concept", and even twenty years later in 1982, they repeated the statement that it was erroneous (p. 69–70) and the result of "urinary stress incontinence".

Late 20th century awareness

The topic did not receive serious attention again until a review by Josephine Lowndes Sevely and JW Bennett appeared in 1978. This latter paper, which traces the history of the controversies to that point, and a series of three papers in 1981 by Beverly Whipple and colleagues in the Journal of Sex Research

, became the focal point of the current debate. Whipple became aware of the phenomenon when studying urinary incontinence, with which it is often confused. As Sevely and Bennett point out, this is "not new knowledge, but a rediscovery of lost awareness that should contribute towards reshaping our view of female sexuality". Nevertheless, the theory advanced by these authors was immediately dismissed by many other authors, such as physiologist Joseph Bohlen, for not being based on rigorous scientific procedures, and psychiatrist Helen Singer Kaplan

Controversy, debate and feminist criticism

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. This debate has been influenced by popular culture, pornography, and physio-chemical and behavioral studies. There is some resistance from feminists to what has been perceived as a male lens in interpreting the data and construct. Often the debate is also tied to the existence of the G-spot

s and ducts and presumed source of the ejaculated fluid, and therefore it has been variously stated that stimulation of this spot results in ejaculation. 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, while in a sharply critical response, Alzate states that direct experimentation fails to provide any evidence. Alzate states:

 argues that the debate is confused by the discussion of two separate phenomena. She comments that Alzate simply dismisses women's subjective experiences in favour of rigorous scientific proof, and is typical of male sexologists withholding the validity of experience from women. 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." For some, she states, it is more a matter of belief than of physiology. Bell further questions why feminists have not been more outspoken in defense of women's control over female ejaculation, pointing out that the literature frames the discussion in only five separate ways; procreation, sexual pleasure, deviance, pathology, and a scientific mystery.

The discussion entered popular culture in 1982 with the publication of the best-selling book The G Spot and Other Recent Discoveries About Human Sexuality
The G Spot and Other Recent Discoveries About Human Sexuality
The G Spot and Other Recent Discoveries About Human Sexuality, published in 1982 by Alice Kahn Ladas, Beverly Whipple and John D. Perry is a controversial book that argued for the existence of the Gräfenberg Spot and popularised the term "G-Spot"...

, by Ladas, Whipple, and Perry. The book discussed female ejaculation and brought the issue back into discussions of women's sexuality both in the medical community and among the general public. This was a popular account of three papers by the authors, the previous year, at the suggestion of Alice Khan Ladas.
Rebecca Chalker notes that this book was largely met with scorn, skepticism and disbelief. The chapter on 'Female Ejaculation' is largely based on anecdotal testimony, and illustrates another issue in the debate, the weight placed on anecdotes and small numbers of observations rather than biomedical investigation or clinical trials. Importantly, a number of the women stated that they had been diagnosed with urinary incontinence. The book advances another feminist theory: that because women's pleasure in their sexuality has been historically excluded, the pleasure of ejaculation has been either discounted or appropriated by health professionals as a physiological phenomenon. Whipple continued to publicise her discoveries, including a 9 min video made in 1981 Orgasmic Expulsions of Fluid in the Sexually Stimulated Female. In 1984, the Journal of Sex Research described the debate surrounding female ejaculation as 'heated'.
Josephine Sevely then followed up her 1978 study by publishing "Eve's Secrets: A new theory of female sexuality" in 1987, emphasising an integrated rather than fragmented approach to understanding female sexuality, with the clitoris, vagina and urethra depicted as a single sexual organ. This not only challenged the traditional fragmentation of female sexuality into clitoral vs. vaginal sensation, but also sexualised the urethra.

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 2002 following the publication of 'The G-spot: A modern gynecological myth' by Terrence Hines.
As of 2007, and 2008
the existence of a female prostate and of ejaculation are a matter of debate, and articles and book chapters continue to appear with subtitles such as "Fact or Fantasy".

Research

Much of the problem in arriving at a consensus relates to a failure to adopt generally agreed-on definitions or research methodology. Research has used highly selected individuals, case studies, or very small numbers of subjects, making generalization difficult. For instance, much of the research into the nature of the fluid focuses on determining whether it is or contains urine. There are also problems involved in the collection of specimens and issues of contamination. 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
Retrograde ejaculation

 into the urethra towards the bladder. The best current data comes from studies where women have abstained from coitus, and where their own urine is used as a control both pre and post-orgasm. 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, and that the biochemical profile of the para-urethral tissues varies with age.
Other issues relate to the sensitivity and specificity of the markers chosen. The key questions are the source of the fluid produced, and its composition. Some relevant findings have been presented in conferences but never published in peer review journals, and many others are in difficult to access resources.

Relation to urinary incontinence

Towards the later part of the twentieth century, there was significant confusion between female ejaculation and urinary incontinence
Urinary incontinence
Urinary incontinence is any involuntary leakage of urine. It is a common and distressing problem, which may have a profound impact on quality of life. Urinary incontinence almost always results from an underlying treatable medical condition but is under-reported to medical practitioners...

. In 1982, Bohlen explained the accepted wisdom;
Scientific studies from the 1980s and later have demonstrated that the substance produced is distinct from urine, though it does show similarities such as alkalinity with urine. A recent study of women who report ejaculation found no evidence of any urological problems, suggesting these two conditions (ejaculation and coital incontinence) are quite distinct physiologically, although perhaps not always distinguishable in a particular individual's mind. Davidson's study of 1,289 women found that the sensation of ejaculation was very similar to that of urination. The best evidence indicates that most fluid expelled during female orgasm is urine. One study used urethral catheterization in order to separate urine from orgasmic expulsions from elsewhere in the body. Seven women claiming to have ejaculations expelled large volumes of urine through the catheter at orgasm, and little to no other fluid. No catheterization study has shown large volumes of fluid expelled at orgasm from any source other than the bladder.

It may be important for physicians to establish whether there is in fact any incontinence in women who report ejaculation, to avoid unnecessary interventions.
It is also important for physicians to distinguish orgasmic ejaculation from vaginal discharges which may require further investigation and treatment. In individual cases, the exact source of any reported discharge may not be obvious without further investigation.

Nature of fluid

Critics have maintained that ejaculation is either stress incontinence or vaginal lubrication

levels. Early work was contradictory; the initial study on one woman by Addiego and colleagues reported in 1981, could not be confirmed in a subsequent study on 11 women in 1983,
but was confirmed in another 7 women in 1984. In 1985 a different group studied 27 women, and found only urine, suggesting that results depend critically on the methods used.

, 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.

Source of fluid

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 0.2–6.6 mL (0.04–1.3 tsp) (95% confidence interval

), with a maximum of 13 mL (2.6 tsp). Therefore claims of larger amounts of ejaculate are likely to contain at least some amount of urine. The eleven specimens analyzed by Goldberg in 1983, ranged from 3–15 mL (0.6–3.0 tsp). One source states that Skene's glands are capable of excreting 30–50 mL (6–10 tsp) in 30–50 seconds, but it is unclear how this was measured and has not been confirmed. One approach is to use a chemical like methylene blue

 so that any urinary component can be detected. Belzer showed that in one woman he studied, the dye was found in her urine, but not her orgasmic expulsion.

PAP and PSA have been identified in the para-urethral tissues, using biochemical and immunohistochemical methods, suggesting that the ejaculate likely arises from the ducts in these tissues, in a manner homologous to that in the male. Another marker common to the prostate/para-urethral tissue in both sexes is Human Protein 1.

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.

 suggests that it may have an anti-microbial function, protecting from urinary tract infections.

Social significance

Sexual functions, and orgasm in particular, remain poorly understood scientifically, as opposed to politically and philosophically. Regardless of the facts relating to the details of female ejaculation, the social significance of the popular accounts through the feminist health care movement has been considerable.

Many women, before learning about ejaculation, experienced shame or avoided sexual intimacy under the belief that they had wet the bed. Others suppressed sexual climax, and sought medical advice for this "problem," and even underwent surgery.

There are, however, concerns. 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 Galen

ic view, it was incomplete. Furthermore, overemphasis of ejaculation may induce performance anxiety. For the reason that 'sameness' has been construed as a male perspective, some feminists reject the term ejaculation. Others argue it should be retained as a distinctive feminine characteristic distinguishable from the male, and imbued with different properties and purpose. A third concern is that of the increasing 'medicalisation' of women's sexuality, as expressed by Leonore Tiefer which finds its most extreme manifestation in the concept of female sexual dysfunction.
Tiefer has expressed concern that overemphasising ejaculation will drive women who might feel inadequate to seek medical attention, as has the Boston Women's Health Collective. Other criticism comes from Barbara Ehrenreich
Barbara Ehrenreich
-Early life:Ehrenreich was born Barbara Alexander to Isabelle Oxley and Ben Howes Alexander in Butte, Montana, which she describes as then being "a bustling, brawling, blue collar mining town."...

  and colleagues who see this new sexuality as one that privileges the male in control, penile retention and body position, but this is denied by others.

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. Regardless, countless workshops now exist to teach women that learning how to ejaculate is an important form of feminine sexual expression. Sundahl describes it as a birthright and essential part of female creativity.

Legal implications

The presence of chemical markers such as PSA or PAP in the female genital tract has been considered evidence in rape trials, 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.
