The Science of Attraction

Here is an excerpt from BBC:

High testosterone in women makes them more attracted to masculine actors such as Daniel Craig, with men favouring the femininity typified by Natalie Portman.

The claim has been made by the University of Aberdeen's Face Research Laboratory.

Their research says that changes in testosterone levels affect the extent to which men and women are attracted to different types of faces.

Dr Ben Jones, a psychology lecturer, said: "People preferred different types of face in the session where their testosterone level was highest than in the session where it was lowest.

"When men's testosterone levels were high, they were more attracted to feminine women. When women's testosterone levels were high, they were more attracted to masculine men.

"Since masculine men and feminine women are thought to produce the healthiest children and sex drive is higher when testosterone levels are also high, these findings suggest that men and women in hormonal states where their interest in sex is highest, show stronger attraction to high quality - or healthy - mates."

Colleague Dr Lisa Welling added: "We tend to think that attraction is relatively stable over time.

"However, our research shows that attraction is affected by fluctuations in testosterone levels."
