hands smell

Gender can be determined by how the hand smells.

A 2023 study from Florida International University had 30 men and 30 women hold cotton balls for 10 minutes in hands that hadn’t been washed for at least an hour.

Those cotton balls were analyzed using gas chromatography and mass spectrometry to identify the individual chemicals that made up the various Volatile Organic Compounds of the participants.

Using a type of data analysis known as chemometrics, researchers identified the gender of the participants based on their hand odor with stunning 96.67% accuracy.

Men’s and women’s hands produce different odors. One day, subtle chemical fingerprints might prove volatile to a forensic scientist at a crime scene.
