Women’s farts smell worse than men’s — and there’s science to back it up
On average, humans fart up to 23 times a day, but not all of those toots are created equal. Research shows that women’s gas smells worse than men’s, and there’s a scientific reason why.
Back in 1998, Dr. Michael Levitt, a gastroenterologist and prolific researcher known as the “King of Farts,” set out to figure out which gases give flatulence its signature funk.
He recruited 16 healthy adults with no history of gastrointestinal issues and had each of them strap on a “flatus collection system,” which was essentially a rectal tube connected to a bag.
After the participants chowed down on pinto beans and took a laxative, the researchers collected their subsequent farts.
Next, Levitt and his colleagues ran a gas chromatographic–mass spectroscopic analysis to break down exactly what was inside those bags.
They also put the samples to a sniff test.
Two judges were brought in to rate each fart on a scale of 0 to 8, with 8 being “very offensive.” They were unaware that they were smelling human flatulence.
The judges agreed, rating women’s farts as having a “greater odor intensity” than men’s.
A 2005 study found that heterosexual men were the least bothered if others could hear or smell their toots, while heterosexual women were the most self-conscious.
Not like men haven't known this since the beginning of time, but
