During sexual intercourse and until orgasm, women secrete more or less abundant fluids of different composition. The phenomenon of “female ejaculation” is still sometimes controversial today, the term “ejaculation” is rather reserved for a very specific substance. A new study today sheds some light: it turns out that women excrete fluids in two different ways, and that one of those fluids comes from the bladder.
It has long been believed that the fluids secreted by women during vaginal sexual stimulation are similar to a form of female ejaculation. However, in recent years, urology specialists have distinguished ejaculation from “squirting” (or “squirting”). Study conducted in 2011 indeed he emphasized the fact that the two phenomena were characterized by two different fluids: the fluid expelled during female ejaculation has a milky appearance and biochemically comparable to certain components of male sperm; the fluid expelled during ejaculation/ejaculation has the properties of diluted urine and is produced in larger quantities (the women in question are sometimes characterized as “squirting women”).
It has since been established that true female ejaculation is the release of a thick and whitish fluid produced by the female prostate (on the order of several milliliters), while ejaculation is the expulsion of dilute fluid from the bladder (about ten milliliters or more). Squirting is therefore defined as the involuntary expulsion of fluid through the female urethra following stimulation of the anterior vaginal wall before or during orgasm. But the mechanism underlying this spurt has not been determined. Therefore, Japanese scientists conducted a new study to better understand the phenomenon.
Fluid that comes from the bladder
An estimated 5% of women are affected by squirting; volumes expelled at the time of orgasm can reach several hundred milliliters. However, this phenomenon must be distinguished from urinary incontinence: this spraying, like ejaculation, occurs only during sexual intercourse.
French scientists investigated the nature and origin of this female syringe. The results of their work were the subjectarticle published in 2015 in Journal of Sexual Medicine. We learned that fluid samples excreted by the participants (seven women who reported repeated and massive fluid emissions during sexual stimulation) had comparable concentrations of urea, creatinine, and uric acid—the same as those measured in urine samples collected before sexual stimulation. and after ejaculation.
An ultrasound performed before and after ejaculation showed that the bladder was empty just after the act. In addition, prostate-specific antigen (PSA) was detected in five of the seven participants, suggesting a “marginal contribution of prostatic secretion to the fluid emitted” during intercourse.
Five women (two in their thirties, two in their forties, and one in their fifties) were recruited into this new study; all were able to squirt during sex. For the experiment, the bladder was emptied before sexual stimulation, and the researchers introduced a dye (a mixture of 10 ml of indigo carmine and 40 ml of saline) into the bladder using a urethral catheter. Sexual stimulation was performed to facilitate the expulsion of secretions; these were collected in sterile cups.
Still a taboo topic that needs to be explored
All five women in the study eventually voided (three during manual sexual stimulation and two during penetrative stimulation). In all cases, the fluid in question was blue, confirming that the source was indeed the bladder. All had good bladder control, so urinary incontinence was not involved. PSA and glucose levels were measured in each sample. The fluid was positive for PSA in four participants.
These results thus confirm that the main component of the substance emitted during spraying is indeed urine (which is, however, colorless and odorless). However, it can also contain fluid from Skene’s glands – or paraurethral glands, which are located along the urethra in women and are the equivalent of the prostate in men.
However, in the case of the four women who expelled PSA-positive fluid, it was not clear whether this material was excreted at the same time or released before the urinary fluid because the two fluids mix in the urethra. Some questions remain unanswered, such as knowing why some women are susceptible to this phenomenon and others are not.
More research is needed to further explain this female “double ejaculation”. It will also make it possible to break the taboo that surrounds this topic. A study examining women’s feelings in connection with spraying, he emphasizes that some perceive this phenomenon as a feeling of maximum pleasure and are very proud of it, but others experience feelings of discomfort, embarrassment and shame – feelings essentially linked to ignorance of the phenomenon and uncertainties of the composition of the liquid.
