The phenomenon affects at least 5% women (some studies estimate up to 40%). And yet, despite the fact that the phenomenon is widely known in popular culture, women who squirt are still very little studied scientifically. A recent study, published in August 2022 in The international journal of urology, however, it has made it possible to understand where the liquid expelled by dripping women comes from.
A few years ago, the veil began to lift on this phenomenon, which had remained mysterious for a long time. The search began by proceeding by elimination. Anatomical observation showed for the first time that the expelled fluid does not come from the vagina, but from the urethra, and is therefore not composed of love juice secreted by the Bartholin’s glands. This discarded track published works then he showed that squirting was a very unique physiological phenomenon and not the consequence of a form of urinary incontinence in women that would be triggered at the moment of orgasm.
The female anatomy consists of (from left to right in the image): the clitoris (pink striped), the urethra leading to the bladder (yellow), the vagina (pink striped) leading to the uterus above the which are the ovaries (here in white) and finally to the rectum, the larger cavity on the right.

Science has traditionally considered squirting and female ejaculation to be the same thing. But 2011 job established that two different types of fluids are released through the urethra. A milky fluid secreted in very small amounts during female ejaculation; and a transparent fluid expelled in large quantities by the squirting women. We now know that during female ejaculation, the few milliliters of thick, milky secretions come from small glands, called Skene’s glands, located near the urethra. Also nicknamed “female prostate“Because the fluids they produce contain prostate-specific antigens (PSA), which are used to liquefy sperm in men. One more clue down.
On the trail of the bladder
It remained to understand where the liquid emitted by squirting women comes from. A French obstetrician and gynecologist, Dr. Samuel Salama, postulated in 2014 that the fluid came from the bladder. His study, conducted on 7 patients without urinary incontinence, showed that even after they had emptied their bladders, they filled when they were aroused and then emptied after they had sex. “Sexual arousal would produce urine in an accelerated way”, comments Dr. Salama to Science and Future. For the specialist, the expelled liquid would simply be urine. This study, however, was criticized for squirts of women themselves, explaining that the color and odor of the liquid were very different from their urine.
This time, a Japanese team wanted to be clear and published their results on theInternational Journal of Urology. The team injected a mixture of water and blue dye into the bladders of five leaking women. After being stimulated, the collected liquid was very blue. “This test confirms that the fluid is coming from the bladder. But many questions remain unanswered“, comments to Science and Future Jessica Pafs, an expert in sexology at the University of Gothenburg in Sweden. “We still can’t explain why this fluid, even though it comes out of the bladder, doesn’t seem to have the same composition. More work will be needed.”
The composition still in debate
Japanese works actually have many limitations. Four of the five women recruited appear to be squirting and experiencing female ejaculation. In fact, after analysis, the fluid produced by these four volunteers also contained PSA, the marker for Skene’s glands. Therefore, two liquids would have mixed in the urethra. In addition, the experiment appears to have certain ethical limitations. “If the researcher stayed nearby, the volunteer could not have sex. Thus, the investigator entered the room quietly just before the jets [le phénomène de femme fontaine, ndlr]was able to make a video and collect expelled fluid“, we can read in the study, which specifies “that it is difficult to collect the liquid from the jet because the direction of the ejection is variable.”
The fight of experts continues. One thing is certain, the expelled fluid comes from the bladder, although its composition is still debated. More research, delicate though it may be, seems necessary to find out what exactly makes up this liquid. The study itself goes in this direction. Either “the main component“appears to be urine”we do not know what the expelled liquid is made of; more research needed“, admit the authors. For Dr. Salama, instead, this experiment is only a confirmation that the liquid in question is none other than urine. Miyabi Inoue, the Japanese urologist behind this work, did not respond to questions from Science and Future.
