Let's be honest. Everyone does it. Whether you call it passing gas, breaking wind, or flatulence, it is a universal human experience that transcends culture, age, and—most importantly for our debate today—gender. Yet, there is this weird, lingering social myth that women are somehow "too delicate" for such things, or that men are the undisputed kings of the sulfurous cloud.
The question of who farts more men or women isn't just fodder for locker room jokes or awkward dinner conversations; it’s actually a legitimate area of gastroenterological study. If you’ve ever sat on a couch next to a partner and wondered why one of you seems to be a constant fog machine while the other is silent as the grave, the answer isn't as simple as what’s on your birth certificate.
Biology doesn't care about your manners. It cares about fiber, gut bacteria, and the way you swallow air.
The Great Equalizer: What Science Actually Says
If we are looking strictly at volume and frequency, the data is surprisingly tight. Most healthy adults pass gas between 10 and 20 times a day. That is the baseline.
In a landmark study published in the journal Gut, researchers led by Dr. Michael Levitt—who is basically the godfather of flatulence research (yes, that’s a real thing)—tracked the habits of men and women. They found that when eating the same diet, the frequency of gas passage was nearly identical. Men didn't significantly outpace women in the number of times they "let it rip."
However, there was a tiny, smelly catch.
While the frequency was similar, the concentration of gases sometimes varied. In some tests, women actually produced a higher concentration of hydrogen sulfide. That’s the "rotten egg" smell. So, while a man might produce a larger volume of gas (simply because men are, on average, physically larger and swallow more air), a woman's contribution might be—to put it politely—more potent.
It turns out that size matters, but so does chemistry.
Why Men Often Get the Blame
Social conditioning is a powerful thing. Men are often culturally "permitted" to be louder about their bodily functions. In many circles, a loud fart from a man is met with a laugh or a shrug, whereas the same act from a woman might be met with genuine shock or embarrassment. This creates a massive observational bias. You think men fart more because they don't try as hard to hide it.

Dietary habits also play a massive role here.
Historically, men have been marketed diets higher in red meat and heavy proteins, which take longer to break down and can lead to more fermentation in the gut. But as dietary habits shift and more people embrace plant-based "superfoods" like kale, beans, and broccoli, the "fart gap" is closing. If you eat a bowl of lentils, your colon doesn't care about your gender; it’s going to produce methane.
The Role of Hormones and Anatomy
We can't talk about who farts more men or women without looking at the unique biological hurdles women face. This is where the "men fart more" theory starts to fall apart.
Progesterone is a bit of a troublemaker. During various stages of the menstrual cycle, specifically the luteal phase, progesterone levels spike. This hormone acts as a muscle relaxant. While that sounds nice, it also relaxes the smooth muscles of the intestines. The result? A "slowed down" digestive tract. When waste sits in the colon longer, it ferments. Bacteria have a field day.
This is why "period farts" are a very real, documented medical phenomenon.
Furthermore, during pregnancy, the physical displacement of organs means the intestines are literally being squeezed. This trapped air has to go somewhere. So, while the "average" daily stats might look equal, women often experience intense fluctuations in gas production that men simply don't have to deal with. It's a physiological rollercoaster.
The Mechanics of Gas: It’s Not Just About Food
Flatulence comes from two places: swallowed air (aerophagia) and the breakdown of food by gut bacteria.
If you drink through a straw, chew gum, or talk rapidly while eating, you are pumping air into your system. Men, who statistically eat faster than women, might swallow more air. This leads to what doctors call "eructation"—belching—but a good portion of that air travels all the way through the GI tract.

Then you have the microbiome.
Inside your large intestine, trillions of bacteria are munching on the carbohydrates your small intestine couldn't digest. These are called FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols). As these bacteria eat, they release gas as a byproduct.
- Hydrogen: Odorless, but adds volume.
- Methane: Also odorless, produced by specific "methanogenic" microbes.
- Hydrogen Sulfide: The culprit behind the stench.
Interestingly, research suggests that some people are "methane producers" while others are "hydrogen producers." This is determined more by your individual gut flora than by whether you are a man or a woman. You could be a 110-pound woman with a microbiome that produces massive amounts of methane, making you "gassier" than a 250-pound male athlete.
Is One Gender More "Potent" Than the Other?
Back to Dr. Levitt’s research. In one specific study where participants were fed pinto beans (the classic "musical fruit"), the results were fascinating. The women in the study actually produced gas with a significantly higher concentration of sulfur.
The theory? It might be related to how women metabolize certain compounds or the specific transit time of food through the female gut, which tends to be slightly slower than in men. Slower transit equals more time for sulfur-producing bacteria to do their dirty work.
So, if we are judging "who farts more" by the sheer impact on a room's air quality, women might actually hold the crown in certain scenarios.
When Flatulence Becomes a Health Warning
Regardless of gender, there's a point where gas stops being a joke and starts being a symptom. Doctors generally don't care how much you fart unless it's accompanied by pain or a change in "normal" habits.
If you find that your gas is suddenly coupled with:

- Intense bloating that doesn't go away.
- Sharp abdominal cramping.
- A sudden shift in bowel movements (diarrhea or constipation).
- Unintentional weight loss.
Then it isn't a "men vs. women" debate anymore. It’s a "check for SIBO (Small Intestinal Bacterial Overgrowth) or IBD (Inflammatory Bowel Disease)" conversation. Celiac disease and lactose intolerance are also prime suspects for excessive gas that feels "different" than the usual daily breeze.
Breaking the Stigma
The reality of who farts more men or women is that the biological difference is negligible. The perceived difference is almost entirely social.
We live in a world where men's bodies are allowed to be functional and messy, while women's bodies are often expected to be ornamental and "clean." This leads to women "holding it in," which is actually quite bad for you. Holding in gas can lead to distension, bloating, and even heartburn as the air looks for another way out.
Yes, if you hold a fart in long enough, it can actually be reabsorbed into the bloodstream and exhaled through your lungs. Think about that next time you’re trying to be "polite" on a first date.
Practical Ways to Manage the Frequency
If you feel like you’re on the losing end of the flatulence battle—regardless of your gender—there are ways to dial it back without living on a diet of ice cubes.
- Slow down your eating. Most of the volume in a fart is just air you swallowed because you were rushing through lunch.
- Identify your triggers. For some, it’s dairy. For others, it’s the sugar alcohols (like xylitol or sorbitol) found in "sugar-free" candies and gums.
- Walk it off. Physical movement helps the gut move gas through more efficiently, preventing the painful buildup that leads to "explosive" moments later.
- Check your fiber. If you go from zero fiber to "high fiber" overnight, your gut bacteria will panic and produce a localized hurricane. Scale up slowly.
- Peppermint oil. This can help relax the muscles in the gut, allowing gas to pass more easily and with less pain.
The Bottom Line
Men might make more noise and take more credit, but women are right there with them in the trenches. Biology is remarkably fair in this regard. Whether it’s the result of a high-protein "bro diet" or the hormonal shifts of a menstrual cycle, both genders are equally capable of clearing a room.
The next time you hear a mysterious sound or catch a suspicious scent, don't look for a gendered explanation. Look at the menu.
Actionable Steps for Better Gut Health
If you want to reduce the frequency or intensity of your flatulence, start by keeping a "gas diary" for three days. Note what you eat and when the gas peaks. Most people find a direct link to specific fermentable carbs within 2 to 6 hours of eating. Switch to activated charcoal supplements if you have a big event coming up, but don't rely on them daily as they can interfere with medication absorption. Finally, prioritize your microbiome with fermented foods like kimchi or kefir, which can help balance out the "stinky" bacteria with more neutral varieties.
