When aroused, some women may experience squ*rting, or a rather noticeable discharge of fluid. What it is exactly and where it comes from has been hotly debated: female eja*ulation or adult bedwetting? Researchers are now saying that squ*rting is essentially involuntary urination.
Female eja*ulate is technically the small amount of milky white fluid that’s expressed when cl1maxing.Squ*rting, on the other hand, results in a much larger gush of a clear fluid, which comes from the urethra, the duct where urine is conveyed from the bladder. The findings, which combine biochemical analyses with pelvic ultrasounds, were published in the Journal of $exual Medicine on Christmas Eve.
A French team led by Samuel Salama from Hopital Privé de Parly II recruited seven healthy women—who’ve reported recurrent and massive fluid emission (enough to fill a cup) during $exual stimulation—to undergo “provoked $exual arousal.” The team conducted pelvic ultrasound scans after urination and during $exual excitation just before and after the sq*irting event.
All of the women had empty bladders before $exual excitation, however, urine collected just before sq*irting showed that the bladder was filling up. Urine sampled after sq*irting revealed that the bladder had been emptied again, revealing the origin of the squirted liquid.
The researchers also analyzed chemical concentrations in the urine samples (before arousal and after sq*irting) as well as the squi*ting sample itself. These included urea, uric acid, creatinine (a byproduct of muscle metabolism), and prostatic-specific antigen (PSA). The latter is a protein that’s produced in men’s prostate glands and in the “female prostate” called the Skene glands; PSA is found in “true” female eja*ulate. Urea, uric acid, and creatinine concentrations were comparable in all of the urine and sq*irt samples. However, PSA, which was not detected before $exual simulation in six of the women’s urine samples, were present in urine collected after sq*irting and in the sq*irt sample in five of the women.
Sq*irting, they found, is essentially the involuntary emission of urine during $exual activity—though there’s also a small contribution of prostatic $ecretions as well. Salama’s team is now working on a protocol to test whether the kidneys work faster to produce urine during $exual stimulation than at other times, New Scientist explains. And if so, why.
