Few subjects created as much controversy in sexology literature in the late 20th century as the phenomenon known as "female ejaculation". Some women (anywhere from 6% to 69%, depending on the survey) report excreting fluid at the moment of orgasm. Some medical experts believe the fluid is secreted by the paraurethral ducts through and around the human female urethra, but the exact source and nature of the fluid continue to be a topic of debate among medical professionals [3].

Anatomy

Several anatomical structures are believed to be involved with female ejaculation (see video for more anatomical detail).

The Clitoris

Clitoral stimulation is reportedly an important factor for many women who ejaculate.

The structure of the clitoris and deeper structures of female pelvis are still subject for study and debate in anatomy, physiology, sexology and psychology. The clitoris is a very complex structure, mostly internal, partially visible in the front side of vulvar vestibule as the glans – a pea-shaped protrusion covered by the clitoral hood. The clitoris holds some 8,000 sensory nerve endings, a greater concentration of touch-sensitive nerves than any other structure in the body – and more than the head of the penis.

The clitoral body extends up inside the perineum before reversing direction and branching, resulting in an inverted "V" or wishbone shape to form the crura (singular crus – legs). Clitoral tissue surrounds the urethra, and extends along both sides and the back of the vagina.

Erectile tissue contains vascular sinuses (cavities) that are capable of becoming distended and rigid as the result of being filled with blood during sexual arousal. In men, all erectile tissue is concentrated in the shaft of the penis while in women it is distributed throughout the vulva. Both derive from the same embryonic structures. The glans of the clitoris corresponds to the head of the penis and the labia majora correspond to the scrotum.

The external urethral orifice (urinary meatus) is between the clitoris and the vagina. This fleshy mound can be extremely erotically pleasurable when stimulated. It is also referred to as the U-Spot - the highly sensitive erectile tissue just above the urethra, between the clitoris and the urethra.

Glands

The Bartholin’s glands are located to the left and right of the back of the vaginal opening – picturing the vulva as a clock, they are located at four and eight o'clock. They are too small to perceive in their normal condition. They provide around a third of the lubrication fluid under normal circumstances.

The Skene's glands (also known as the lesser vestibular glands, periurethral glands, skene glands, paraurethral glands, or female prostate) are located on the front wall of the vagina, around the lower end of the urethra. They drain into the urethra, near the urethral opening and may be near or a part of the G-Spot. It has been postulated that the Skene’s glands are the source of female ejaculation as they secrete a sometimes large amount of lubricating fluid, which is mostly filtered blood plasma. Skene's glands have highly variable anatomy, and in some women they appear to be absent entirely. This may explain the ongoing difficulty in establishing a scientific consensus on the details of the G-spot and female ejaculation.

The G-Spot

The Gräfenberg Spot, often called the G-Spot, is topic for fierce disagreements over its existence as a distinct structure, definition or location. Many women report that it is a sensitive erogenous zone that can lead to powerful orgasms and female ejaculation.

The G-Spot is typically described as being located one to three inches (2.5 to 7.6 cm) up the front vaginal wall fro the entrance of the vagina. While not perceivable in non-aroused condition, the G-Spot becomes erect with arousal, and can then be felt as a bumpy or swollen area.

Prevalence

Much of the problem in arriving at a consensus about the phenomenon of female ejaculation relates to a lack of generally agreed definitions, including ongoing debate as to the existence and location of structures such as "the female prostate". In surveys, 35-50% of women report some form of fluid emission at orgasm. Kratchovil [2] surveyed 200 women and found that 6% reported ejaculating regularly, an additional 13% had some experience, and about 60% reported release of fluid without actual gushing.

The media have embraced the notion of female ejaculation with great enthusiasm, and it is not uncommon to find articles suggesting that "all women can ejaculate", and giving men tips on how to make their woman ejaculate.. Such articles can be misleading. It is quite normal to have intense sexual pleasure without female ejaculation, and it is important not to make "squirting" yet another goal that creates yet more performance anxiety for both men and women.

While female ejaculation may have been recently re-discovered, it was well-known in ancient times. Aristotle made mention of female ejaculation. In the Tantric religion, female ejaculate is referred to as amrita, which translates to “the nectar of the Gods.” Galen of Pergamon once wrote that female ejaculate “manifestly flows from women as they experience the greatest pleasure in coitus.” [9]

What Is The Fluid?

Some research distinguishes between female ejaculation and what is colloquially known as squirting or gushing [4]. These terms are used interchangeably by other researchers and the media, which can lead to confusion. 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, while the "squirting" or "gushing" (shown frequently in pornography) is a different phenomenon; the expulsion of clear and abundant fluid from the urinary bladder.

While the clear and abundant fluid has been mistaken for urine by many women, it is different in composition. Various studies have been conducted to determine whether female ejaculation is simply stress incontinence. One approach is to use a chemical like methylene blue, which is secreted in urine. Belzer showed that in one woman he studied, the dye was found in her urine, but not her orgasmic expulsion. [6] A 2007 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 Prostate Specific Antigene (PSA) an enzyme, Prostate Acid Phosphate (PAP), and glucose but lower levels of creatinine were found in the ejaculate than the urine. PSA levels were comparable to those in males. [5]

Where Does The Fluid Come From?

Some researchers have hypothesised that the fluid is secreted by the Skene's glands, because of the presence of PSA. The tissue in the area of the Skene's glands is analogous to the male prostate, and is sometimes referred to as "the female prostate". This tissue is identical in male and female foetuses until a surge of testosterone produces male sexual differentiation in utero.

Others have suggested that the volume of fluid in the clear, "gushing" discharge is too large to be from the Skene's gland alone, and that the only structure capable of storing such large volumes of fluid is the urinary bladder. While the fluid may accumulate in the urinary bladder, it is not urine. It may mix with urine, if urine has already accumulated in the bladder - another reason for the practice of emptying the bladder completely before and after sexual intercourse, which is otherwise recommended for reducing the chances of urinary tract infections.

How Does It Feel?

Women describe ejaculative orgasms in a variety of ways. Some are very aware of the sensation of needing to urinate, or a sensation similar to urinating, during the orgasm, while others are not at all aware of the sensations of the fluid moving through the urethra.
It was a strange feeling; quite different from the orgasms I was used to. It was more of a sublime, gradually intensifying feeling that spread through my body than it was an "unbearably good" sensation. So I only vaguely felt myself ejaculate. The sound of it hitting the bed is what made me aware of what happened. [7]
Some women also report squirting at times when they are highly sexually aroused, but not actually orgasming.
