Yes, squirting is a real physiological event. Studies show that anywhere from 10% to 54% of people with vaginas have experienced it, and researchers have identified the anatomical structures and biochemical processes behind it. The wide range in that statistic reflects differences in how studies define and measure the experience, but the phenomenon itself is well-documented.
What Actually Happens in the Body
During sexual arousal, blood flow increases to the genital area, causing tissues around the urethra to swell. Two small glands on either side of the urethra, called the Skene’s glands (sometimes referred to as the “female prostate”), become engorged. These glands develop from the same embryonic cells that form the prostate in males, which is why they share some of the same functions.
The Skene’s glands secrete fluid during arousal that helps with lubrication. In some people, they also release a thicker, milky fluid during orgasm, similar in composition to certain components of male ejaculate. This fluid contains prostate-specific antigen (PSA), the same protein produced by the male prostate. Biochemical analysis has confirmed that this secretion matches markers found in prostate plasma rather than those found in urine.
Squirting and Ejaculation Are Two Different Things
Medical literature draws a distinction between “female ejaculation” and “squirting,” though the terms are often used interchangeably in everyday conversation. They involve different volumes of fluid, different sources, and different compositions.
Female ejaculation is the release of roughly 1 milliliter of thick, white, milky fluid from the Skene’s glands. It’s a small amount, sometimes barely noticeable, and is rich in PSA. Some researchers have described it as looking like “watered-down, fat-free milk.”
Squirting, on the other hand, involves a much larger volume of clear fluid, ranging from tens to hundreds of milliliters, released in gushes from the urethra. Pelvic ultrasound and biochemical studies have shown that this fluid comes from the bladder. It is chemically dilute compared to typical urine, but it does originate from the same place.
In at least one well-documented case study, both fluids were collected separately during a single orgasm brought on by stimulation of the front vaginal wall. The clear gushing fluid came first, followed by the smaller, milkier ejaculate. This confirmed that the two are distinct events that can happen together or independently.
Why the Confusion About Urine
The fact that squirting fluid comes from the bladder has led to a persistent question: is it just urine? The answer is more nuanced than a simple yes or no. The fluid does pass through the bladder and urethra, and it contains some of the same compounds found in urine. But biochemical analysis shows it also contains PSA and other prostatic markers that urine does not, suggesting the Skene’s glands contribute to the fluid as it passes through. Its composition is distinct enough from a normal urine sample that researchers treat it as its own category.
For many people, the practical takeaway matters more than the biochemistry. The fluid release happens involuntarily during high arousal or orgasm. It is not the same as urinary incontinence, which has different triggers and different patterns.
What Triggers It
Stimulation of the front vaginal wall (the area sometimes called the G-spot) is the most commonly reported trigger. In clinical observations, orgasms produced by 5 to 10 minutes of digital stimulation of this area led to fluid release. That said, some people experience it from clitoral stimulation, penetration, or a combination of types of arousal. There is no single reliable technique that works for everyone.
The Skene’s glands vary in size from person to person, and some people have glands that are barely detectable. This anatomical variation likely explains why some people squirt easily, others experience it rarely, and many never do. None of these outcomes indicate a problem. It is simply a reflection of individual anatomy.
Why the Range in Prevalence Is So Wide
The 10% to 54% range reported in studies is unusually broad, and that gap comes down to methodology. Some surveys ask whether someone has ever experienced any fluid release during sex, which captures a wide net. Others use stricter definitions that separate squirting from ejaculation from arousal-related lubrication. Self-reporting also introduces variability, since people may not notice a small amount of ejaculate or may confuse increased lubrication with ejaculation. What’s clear from the data is that it’s common enough to be considered a normal part of sexual response, not a medical anomaly.
