LOOK HERE TO LEARN ABOUT THE ROLE THAT TESTOSTERONE PLAYS IN THE SCIENCE OF ATTRACTION.

What makes a woman more attracted to a man?

Researchers at Aberdeen University Face Research Laboratory carried out the first study into the role testosterone plays in attraction between the sexes.

During the study, men and women completed four test sessions each conducted a week apart. In each session, volunteers provided a saliva sample which was used to measure testosterone levels

The science of attraction is very interesting. Researchers found that when asked to choose between different types of faces in each session, the subjects’ preferences changed depending on their testosterone level.

Dr. Ben Jones, a psychology lecturer at the university, said: “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.”

Fellow researcher Dr. Lisa Welling said: “We tend to think that attraction is relatively stable over time.

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