Myth busting: Is squirting just peeing?

Myth busting: Is squirting just peeing?

Yep — we’re talking about the mystery fluid that shoots out of some women during orgasm or stimulation. Maybe you’ve seen it in porn, squirted yourself, read about it online, listened to your friend brag about her fountain-like abilities, or wondered if it’s actually legit or just pee.

We’ve known about squirting since the fourth century, where it’s mentioned in several ancient Chinese Taoist texts. Aristotle, an ancient Greek scientist and philosopher, described the emission of female fluids in his medical writings around 300 B.C. These days, doctors remain interested in squirting and are conducting clinical experiments to learn more about it. Is it the same biological response as male ejaculation? And, um, what exactly… gets squirted — is it pee, or something else entirely? Does it come out of the vagina or the bladder?

The intrigue surrounding squirting is definitely not limited to clinicians. Maybe you’ve personally experienced it or have always been curious how it happens. We turned to science to answer your — and our — most pressing questions.

Let’s talk vocab: ‘squirting’ vs. ‘female ejaculation’

While the terms “squirting” and “female ejaculation” are often used interchangeably, research shows these physiological responses and the substances they produce are different.

In this 2011 study, researchers performed biochemical analysis on two distinct female fluids expelled during sex. The “clear and abundant” fluid ejected in gushes was described as being similar to diluted urine. The second liquid was found to be comparable to components of male semen and released in smaller quantities compared to the other. The authors concluded, “The real female ejaculation is the release of a very scanty, thick, and whitish fluid from the female prostate, while squirting is the expulsion of a diluted fluid from the urinary bladder.”

Dr. Madeleine Castellanos, tells BuzzFeed, “Since it’s such a tiny amount and some gets pushed back into the vagina, you may not notice [female ejaculate].”

Squirting for science
In 2014, scientists decided to take their studies of squirting and female ejaculation a step further by performing a biochemical analysis of the fluids emitted (similar to the 2011 study) and pelvic ultrasound scans to observe the bladder. Seven women reporting “massive fluid emission” during sexual stimulation participated in the study.

First, the researchers asked the women to empty their bladders, provide a urine sample, and then undergo a pelvic ultrasound. The second part of the study required the women to become sexually aroused in an examination room, either alone or with a partner. As the women neared orgasm, they were asked to undergo another ultrasound. (Sounds like a turn on, right?) After this second ultrasound, the women resumed sexual stimulation in the exam room. After eventually orgasming and squirting, the researchers requested another urine sample and performed yet another ultrasound. They also collected the squirting sample.

Here’s what they discovered: the first ultrasound confirmed the women’s bladders were empty after using the bathroom before arousal. But the researchers observed a noticeable filling of the women’s bladders from the ultrasound taken right before squirting. After squirting, the third and final ultrasound revealed women’s bladders appeared to be empty once again. This suggested the squirting samples were urine.

When the researchers compared the chemical makeup of the urine and squirting samples, they discovered that they closely resembled each other. (The researchers did not observe the presence of female ejaculate in any of the squirting and post-squirting samples from five out of seven of the women. However, it was present in samples for two participants.)

The authors wrote, “The present data based on ultrasonographic bladder monitoring and biochemical analyses indicate that squirting is essentially the involuntary emission of urine during sexual activity, although a marginal contribution of prostatic secretions to the emitted fluid often exists.” This means the researchers believe that squirting is primarily just pee, though there may be a small amount of fluid from from the female prostate in the liquid, too.

So, if you squirt, what’s on your sheets? According to science, probably just pee. There’s a chance, however, that some female ejaculate may also be present. Thanks to research, we also know that that vaginal squirting is a thing and that it’s quite different from female ejaculation, in terms of how much is produced and where the fluid comes from. (There you have it, Aristotle.)

  • You misread the study.

    5 of the 7 women DID have PSA/ejaculate — the material from the Skene glands — in their squirt sample. Not, as you wrote, that only 2 had the dilution.

    They also noted that the bladder refills extremely quickly during sexual arousal. It takes an hour for the bladder to fill 2oz, and it takes even more to produce the feeling of needing to pee. In these women (as with most of us who squirt), it refilled in the time it took to get aroused — presumably within half an hour. Other similar studies noted that this is very diluted fluid, and while it contains some urine components (like precum and ejaculate in penises), is not the same composition, and does not smell strongly most of the time, if at all.

    Of note: Salama, the lead on the French 2014 study, is mentioned in a New Scientist article as going on to study if the kidney produces more urine during arousal, and if so, why?

    But ultimately, in the last 40 years since western science took notice of this phenomenon, maybe a handful of clinical studies have been done — not counting anecdotal gyno opinions and reviews — and all with very small sample sizes. Until we get more studies with a greater sample size and some quality science on the clitorial/uterine pleasure system….. keep squirtin’.

  • I’ll pee before I play with my jack rabbit and still end up squirting. And it’s not like a ton of time has passed – it’s usually like 10 minutes if I’m doing it right. So either the human bladder fills up fast or it’s not just pee.

  • I play with my sex toy at least once a week during this quarantine, and each time I do , I ALWAYSSSSSSS squirt. First time I did , I was embarrassed (in my own room) because it smelt like light pee, but the sensation felt soooo good . So now when I play with Mr. PINKY (lol), I place a towel and bag underneath so nothing stains . Funny thing… I only squirt with this toy ..never with an actual man =/

    • Lol my friend told me how she is a squirrel. So when I noticed this big stain on my couch she then proceeded to tell me it was from when her and a guy had sex and she squirted. So basically I guess my couch is stained with diluted piss. And she didn’t even tell me til after I asked and then didn’t offer to get it cleaned.
