Ever wonder why female fans flock to male rock stars, even the ones that are sometimes considered not-so-attractive? Researchers at an English university have set out to study why and it seems there may be a scientific reason for that. 

Business Insider reveals that the University of Sussex has released a study that shows that women in their most "fertile phases" are attracted to men who can produce the best music. Their findings indicate that women linked men with strong musical abilities to carrying better genes and thus, better biologically for reproductive purposes.

The study involved 1,500 women with an average age of 28 who were not breastfeeding, pregnant or using hormonal contraception.

The women were presented with two choices: a composer with a simple melody and then a composer with a more complex melody. They were then asked which one they preferred as a short-term sexual partner, and which one they preferred as a long-time partner.

The results? When the women were deemed in their most fertile stages, they preferred the composers with the more complex melody as a short-term sexual partner. For visual artists, however, the same trend did not appear, showing a strong correlation between sexual desire and musical talent.

The link between music and sexual attraction has gone as far back as Charles Darwin, who once hypothesized that the primary function of music is to assist with sexual attraction.

So next time you see a young female fan swooning over an aging rock star, remember that there may be science behind it.
