How Many Women Squirt? What the Research Shows

Roughly four in ten women in the United States report having squirted at least once in their lives, according to a nationally representative probability survey published in 2023. A 2024 Swedish study put that figure higher, at about 58 percent. The gap between those numbers reflects real differences in how researchers ask the question, which populations they sample, and whether “squirting” and “female ejaculation” are treated as one thing or two. What the research consistently shows is that this is not a rare phenomenon, but the science behind it is newer and messier than most people expect.

What the Surveys Actually Report

The most methodologically rigorous estimate for the U.S. comes from a 2023 probability-sample study of women ages 18 to 93, which found that about 40 percent had squirted at some point, with a median frequency among those who had experienced it of three to five times total.¹ That figure lines up with an older U.S. and Canadian survey of professional women, which also found a 40 percent self-reported rate of fluid release at orgasm.²

The Swedish study, published in 2024, surveyed a broader online sample and found that 58 percent of women reported personal experience with ejaculation or squirting, with another 6 percent unsure whether they had experienced it. Women with non-heterosexual orientations were more likely to report the experience, at about 63 percent compared to 52 percent of heterosexual women.³ A systematic review covering clinical studies placed the prevalence range even wider, at 10 to 54 percent, depending on the study’s definition and methods.⁴

Why such a wide range? Part of the problem is that many studies lump squirting and female ejaculation together as one event. As we’ll see, researchers now consider them distinct phenomena. Surveys that ask about “any noticeable fluid release during orgasm” will naturally capture a broader group than studies that specifically ask about a large gush of liquid. And self-report has obvious limits: some women may not recognize what happened, some may underreport out of embarrassment, and others may interpret ordinary lubrication as something more.

Two Different Phenomena With the Same Nickname

One of the most persistent sources of confusion, both in popular culture and in older research, is treating squirting and female ejaculation as synonyms. Current evidence says they are not. They involve different fluids, different sources, and different mechanisms, even though they can happen at the same time.

Female ejaculation is the release of a small amount of thick, whitish fluid from the paraurethral glands, also called Skene’s glands. The volume is typically a few milliliters at most. This fluid contains high concentrations of prostate-specific antigen, the same protein produced by the male prostate, and very little of the chemical markers you’d find in urine.⁵ A systematic review and meta-analysis of biochemical studies confirmed that female ejaculate consistently shows elevated PSA and minimal urinary content, fitting a paraurethral gland origin.⁶

Squirting, by contrast, involves a much larger volume of fluid, often described as 10 milliliters or more, and sometimes considerably more than that. This fluid is clear and watery, chemically similar to dilute urine, with elevated levels of urea and creatinine.⁷ It comes from the bladder, not the paraurethral glands. The two phenomena can overlap: a woman may experience both a small ejaculate from the Skene’s glands and a larger squirt from the bladder simultaneously, making it difficult to tell them apart without lab analysis.⁵

This distinction matters for interpreting prevalence numbers. A woman who notices a small amount of milky fluid on her partner or on bedsheets is probably experiencing female ejaculation. A woman who reports a noticeable gush that soaks through fabric is more likely squirting. Survey questions that don’t distinguish between these will blend the two populations together, inflating or deflating the number depending on what the researcher intended to measure.

How Researchers Confirmed the Bladder Connection

The strongest evidence that squirting fluid originates in the bladder comes from a small but carefully designed French study that used real-time ultrasound imaging. Participants emptied their bladders before sexual stimulation, and an initial ultrasound confirmed the bladders were empty. As arousal progressed, a second ultrasound showed the bladders had rapidly refilled. Immediately after squirting, a third ultrasound showed the bladders were empty again.⁸ Biochemical testing of the expelled fluid confirmed it was chemically similar to urine, though in some participants there was a small contribution of prostatic secretions, consistent with fluid from the Skene’s glands mixing in.⁹

A separate case study, examining a woman who could reliably produce both types of fluid, showed the same pattern: the larger-volume fluid matched dilute urine in its chemical profile, while the smaller-volume secretion had a biochemical signature comparable to components of male semen, with very high PSA levels.¹⁰ Together, these findings make a strong case that squirting specifically involves rapid bladder filling during arousal followed by involuntary expulsion, while female ejaculation is a separate glandular secretion.

Why It Is Not the Same as Incontinence

One of the first things many women worry about when they experience squirting is whether something has gone wrong with their bladder control. The chemical similarity to urine doesn’t help with that anxiety. But the research draws a clear line between squirting and coital incontinence, which is involuntary urine leakage during sex caused by conditions like stress urinary incontinence or an overactive bladder.

A urodynamic study that specifically tested women who reported ejaculation found that none of them showed detrusor overactivity, the involuntary bladder-muscle contractions associated with urge incontinence. Their bladder diaries and questionnaire results were all within the normal range.¹¹ In clinical terms, squirting appears to be a distinct physiological event rather than a symptom of bladder dysfunction. A systematic review noted that coital incontinence and female ejaculation are separate conditions with different underlying mechanisms, even though they can be hard to tell apart without clinical testing.⁴

That said, coital incontinence is not uncommon on its own. The same systematic review estimated its prevalence at anywhere from less than 1 percent to as high as 66 percent depending on the population studied, with the higher numbers found among women already diagnosed with lower urinary tract symptoms. If fluid loss during sex is accompanied by leakage during coughing, sneezing, or exercise, that’s worth discussing with a doctor. If it only occurs around orgasm and there are no other symptoms, squirting is the far more likely explanation.

The Anatomy Behind It

Researchers have moved away from thinking of the “G-spot” as a discrete anatomical button. Instead, current evidence points to something called the clitourethrovaginal (CUV) complex, a zone where the internal structures of the clitoris, the urethra, and the front wall of the vagina all press close together. During vaginal penetration, ultrasound studies have shown that the anterior vaginal wall moves downward, increasing contact between this region and whatever is applying pressure.¹² This combined stimulation appears to be what triggers both vaginal orgasm and, in some cases, squirting or ejaculation.

The CUV complex is described as functional, dynamic, and hormone-dependent, which means its sensitivity and responsiveness vary from person to person and can change with hormonal shifts across the lifespan.¹³ This natural variability goes a long way toward explaining why some women squirt easily, others never do, and still others experience it unpredictably. It is not a skill to be learned or a deficiency to be corrected. The underlying anatomy simply differs from one body to another.

The Skene’s glands themselves, which are the source of true female ejaculate, also vary considerably in size and development. These glands are the histologic equivalent of the male prostate, sharing similar tissue structure.¹⁴ In some women they are well developed, in others they are vestigial. This anatomical variation likely explains part of the prevalence spread in surveys. The older survey that found a 40 percent ejaculation rate also noted a strong association between recognizing a sensitive area on the front vaginal wall and reporting ejaculation: 82 percent of women who identified that sensitive area also reported fluid release at orgasm.²

What It Feels Like and How Partners React

The emotional experience of squirting spans an enormous range. A qualitative Swedish study found that women’s descriptions went from calling it “amazing,” “a superpower,” and even a feminist statement, all the way to describing it as unpleasant or shameful.¹⁵ The Swedish survey data found that among women who had never experienced it, about 29 percent actively wished to, while a quarter were indifferent and roughly one in ten had no desire for it at all.³

A partner’s reaction turns out to be one of the strongest factors shaping how a woman interprets the experience. A recent qualitative analysis identified four distinct relational patterns around squirting:

Validated: The partner treats it as a neutral bodily response, responding with support or casual acceptance.
Avoided: The partner reacts negatively or dismissively, and the woman comes to see it as undesirable.
Desired: The partner views squirting as proof of sexual prowess or confirmation of the woman’s climax, sometimes in ways that don’t match her own experience.
Coerced: The partner pressures the woman to squirt, pushing beyond her boundaries to satisfy his own desire for the response.

The “desired” and “coerced” categories are where things get complicated. When a partner treats squirting as a trophy or a goal, the woman’s own pleasure can get sidelined. One participant in a qualitative study described the frustration of constantly thinking about whether her partner was enjoying himself instead of focusing on her own experience.¹⁶ That pressure can turn what would otherwise be a pleasurable or neutral event into a source of performance anxiety.¹⁷

How Pornography Warps Expectations

Squirting has become a prominent genre in pornography, which has shaped public understanding in ways that don’t align well with the science. On screen, squirting is presented as a dramatic, high-volume event that happens reliably on demand as a visible sign of intense pleasure. The research suggests a different reality: for many women it happens unpredictably, the volume varies, the sensation is not always tied to orgasm intensity, and it is not something that can simply be willed into existence.

Researchers studying young women’s experiences found that pornography was a primary source of information about squirting for many participants, and it often set unrealistic benchmarks for both the women themselves and their partners. The emphasis in pornographic depictions on squirting as the ultimate proof of arousal can create pressure to perform, particularly in heterosexual encounters where a male partner has learned about squirting primarily through porn.¹⁶ This dynamic feeds directly into the “coerced” relational pattern described above, where partners push for squirting as a scripted performance rather than accepting whatever happens naturally.

The disconnect matters clinically too. Women who believe squirting should look the way it does in pornography may feel inadequate if their experience is more subtle, or alarmed if they produce more fluid than expected. And because pornography rarely distinguishes between squirting and female ejaculation, viewers absorb the idea that there is one phenomenon rather than two, which can make it harder to have informed conversations with partners or healthcare providers.

An Evolutionary Hypothesis That Remains Unproven

One recent paper proposed that female ejaculatory fluids might serve a reproductive function by raising vaginal pH from its normally acidic range into a zone more hospitable to sperm, and by releasing substances that help sperm reach the egg.¹⁸ It’s an interesting idea, but it was published in a journal devoted to speculative hypotheses, and no controlled study in humans has tested whether ejaculation during sex actually improves fertility outcomes. Given that roughly half of women report never squirting, any reproductive advantage would need to be modest at best to square with those numbers. For now, this remains firmly in the “maybe, but we don’t know” category.

Centuries of Observation, Decades of Confusion

Female ejaculation is not a modern discovery, even if it sometimes feels like one. Descriptions appear in Chinese Taoist texts dating to the fourth century, in Indian Kāmaśāstra literature from the seventh century onward, and in Western writing as far back as Aristotle around 300 B.C. The Dutch physician Reinjier De Graaf provided the first scientific description in the seventeenth century and was the first to call the periurethral glands the “female prostate.”¹⁹ The topic then largely vanished from Western medical literature until Ernst Gräfenberg’s 1952 paper on the role of the urethra in female orgasm, which also lent its initial to the “G-spot.”

Despite that long trail of references, modern science has been slow to catch up. A review of the literature noted that views about female ejaculation remain inconsistent, with no clear consensus on its function.²⁰ The field suffers from small sample sizes, inconsistent terminology, and the practical difficulty of studying sexual arousal in a laboratory. Most of the imaging and biochemical studies that have clarified the squirting-versus-ejaculation distinction were conducted in the last fifteen years, often with only a handful of participants. Larger and more rigorous studies are needed, but they are hard to fund and harder to recruit for, which means the evidence base grows slowly. What we have is enough to sketch the outlines of what’s happening, but not enough to answer all the questions people have about why.
