Male sweat

The smell of a man's sweat differs according to what mood he is in and women can pick up on changes that indicate attraction, according to new research.
.
The study, led by Dr Denise Chen, assistant professor of psychology at Rice University, in Texas, America, involved introducing two types of male sweat to 19 women in their 20s - one type was labelled 'normal', the other 'sexual'.
.
The sweat was gathered from a selection of men who had polyester pads attached to their armpits.
.
The 'normal' sweat was gathered during a 20-minute session in which the men were asked to watch educational videos.
.
They were then asked to watch 20 minutes of an erotic video, during which the 'sexual' sweat was gathered.
.
The female participants were exposed to these different scents while researchers monitored their brain activity.
.
The women did not realise it but their brains not only recognised the scents but responded to them.
.
Dr Chen said the 'sexual' sweat lit up different regions of the participants' brains.
.
She added her results suggested the female brain is capable of recognising the smell of a man who is attracted to her.
.
Dr Chen and her colleagues now intend to expand their research by look at how these scents actually affect a man and woman's behaviour towards each other.
