Smelling a single component of male sweat alters levels of cortisol in women.

Rodents use chemosignals to alter endocrine balance in conspecifics. Although responses to human sweat suggest a similar mechanism in humans, no particular component of human sweat capable of altering endocrine balance in conspecifics has yet been isolated and identified. Here, we measured salivary levels of the hormone cortisol in women after smelling pure androstadienone (4,16-androstadien-3-one), a molecule present in the sweat of men that has been suggested as a chemosignal in humans. We found that merely smelling androstadienone maintained significantly higher levels of the hormone cortisol in women.

These results suggest that, like rodents, humans can influence the hormonal balance of conspecifics through chemosignals.

Critically, this study identified a single component of sweat, androstadienone, as capable of exerting such influence.

This result points to a potential role for synthetic human chemosignals in clinical applications.

Hey....

The only thing I think of when I get to handle

And then wash my husband's sweat drenched clothes

From working out at the club is YUCK!!!

It makes me want to throw up...

The best was prior to his dx. for Lyme when he kept asking me to smell it.

He swore his sweat smelled like anmonia.

Hardly an turn on.

Hugs,

Geneal

Actually, I like the smell of my husband's sweat.

Clean sweat, that is.
