Yes, squirting is a real physiological response. It has been documented in clinical studies using ultrasound imaging and biochemical analysis, and survey data suggests a majority of women may experience some form of it. That said, the science behind squirting is more nuanced than most people realize, because “squirting” and “female ejaculation” are actually two different things that can happen separately or at the same time.
Squirting and Female Ejaculation Are Not the Same Thing
This is the most important distinction researchers have identified, and it clears up a lot of confusion. Female ejaculation is the release of about 1 milliliter of thick, white, milky fluid from small glands located on either side of the urethra called Skene’s glands (sometimes called the “female prostate”). This fluid contains proteins similar to those found in male semen, including prostate-specific antigen, fructose, and glucose. Skene’s glands actually develop from the same embryonic cells that become the prostate in males, which is why the fluid composition is so similar.
Squirting is something different. It involves a much larger volume of clear fluid, anywhere from tens to hundreds of milliliters, released from the urethra during orgasm or intense arousal. This is the dramatic gush often depicted in pornography. The two events can overlap, though. Squirting fluid sometimes contains small amounts of the same proteins found in female ejaculate, suggesting both glandular secretion and bladder fluid can be released simultaneously.
Where the Fluid Actually Comes From
Researchers have used pelvic ultrasound to track what happens inside the body before, during, and after squirting. In one well-known imaging study, participants emptied their bladders completely, and ultrasound confirmed the bladder was empty. Then, during sexual stimulation, a second ultrasound showed noticeable bladder filling. After squirting occurred, a third scan showed the bladder had emptied again.
This confirms that the large volume of fluid released during squirting originates in the bladder. Chemical analysis backs this up: squirting fluid contains urea, creatinine, and uric acid, all substances produced by the kidneys and collected in the bladder. However, the fluid is not identical to regular urine. It’s significantly more dilute. One case study found much lower concentrations of urea and creatinine compared to a typical urine sample, with a density close to water. The best description is that it’s a very diluted version of urine, sometimes mixed with a small amount of glandular ejaculate.
This finding trips people up. Learning that squirting fluid comes from the bladder makes some people dismiss it as “just peeing,” but that oversimplifies what’s happening. The bladder fills rapidly during arousal in a way it doesn’t during normal daily life, and the fluid released is chemically distinct from a standard urine sample. It’s a real physiological event triggered by sexual stimulation, not a loss of bladder control.
What Triggers It
Squirting is most commonly linked to stimulation of the G-spot, which isn’t a separate structure but rather a section of the internal clitoral network that can be accessed through the front wall of the vagina. Stimulating this area puts indirect pressure on the surrounding tissue, including the urethra and Skene’s glands. Clitoral stimulation and vaginal stimulation more broadly can also lead to ejaculation or squirting in some people.
Not everyone experiences it the same way. Some people squirt easily and regularly, others only under very specific conditions, and many never do. None of these experiences are abnormal. The variation likely comes down to differences in anatomy (Skene’s glands vary considerably in size from person to person), arousal patterns, and the type of stimulation involved.
How Common It Is
Reliable prevalence numbers are hard to pin down because studies define and measure it differently, and self-reporting on sexual experiences is inherently tricky. One cross-sectional study that combined self-reporting with biochemical analysis of fluid found that about 69% of participants produced urethral fluid related to orgasm. That’s a higher number than many people expect, though it includes any amount of fluid, not just the dramatic gushing that most people picture when they hear the word “squirting.”
Smaller volumes are easy to miss entirely, especially during sex when other fluids are already present. Many people who do experience some form of ejaculation may not even be aware of it. On the other end of the spectrum, the large-volume squirting commonly shown in pornography represents a more extreme version of the response and is less universal than those depictions suggest.
Why the “Is It Urine?” Question Misses the Point
The composition question dominates almost every conversation about squirting, and it’s understandable why. But framing it as a binary, either it’s “real” or it’s “just pee,” creates a false choice. The science shows it’s a distinct event with a specific trigger (sexual arousal), a specific mechanism (rapid bladder filling during stimulation), and a fluid composition that differs from normal urination. It also frequently contains secretions from the Skene’s glands, blending two sources into one release.
For people who experience squirting and enjoy it, the biochemical breakdown of the fluid doesn’t change the experience. For people who feel anxious about it, knowing the science can help. The sensation of needing to release fluid during intense arousal is the body doing exactly what these studies describe: responding to stimulation by filling the bladder quickly and releasing that fluid alongside glandular secretions. It’s a normal part of sexual response for many people, not a sign that something is wrong.
