Gulp: Women's Farts More Stinky

According to Michael Levitt, author of 34 research papers on intestinal gas, “the flatus of women has a significantly greater concentration of hydrogen sulfide" and is deemed to have a significantly worse odor than
men's.

The potency of women's farts is balanced out, however, by the male’s “greater volume of gas per passage.”
