Male Sweat Makes Women Happy

guacamolefoo writes "CNN reports a study by the University of Pennsylvania that involved applying to the upper lips of women a solution containing underarm sweat from men who had not used deodorant in four weeks. It apparently elevated their moods and increased their fertility. Use this knowledge at your own risk."

It's not _sweat_ that smells, it's _stale sweat_.

Not quite - the human have different kinds of sweat glands, which we have over all of our bodies. The greatest concentration of sweat glands are on the palms of our hands and soles of our feet.

The watery kind of sweat is secreted by eccrine sweat glands; this kind of sweat consists of mostly water and some dissolved salts.

The smelly type of sweat comes from the apocrine, or specialized, sweat glands. The reason that the sweat smells is that the apocrine sweat glands in the armpits and genital-anal areas produce sweat that 1) stimulates bacterial growth, and 2) is oilier and is broken down into smelly components.

As a sidenote: yes, we "sweat" in our ear, but the apocrine sweat glands there produce earwax instead of normal sweat.
