The Valentine's Day event, labeled LoveFest, features lectures from three eminent Harvard professors on the science of sex as well as a DJ, alcoholic beverages and a sexy fashion show designed to highlight the science of physical attraction, The Boston Globe reported Thursday.

"I've never seen so many jazzed-up students in my life," said Marc Hauser, one of the organizers of the event and a professor of psychology, organismic and evolutionary biology, and biological anthropology at the university. "Now, the question is, how far will they take it?"

Carmen Collyns, a 19-year-old psychology major, is helping to design the fashion show portion of the event. She said one of the outfits is designed to show how certain waist-to-hip ratios signal health to potential mates, while another aims to illustrate how sexy walks can be a sign of fertility.

"I'm a little worried," Hauser said. "I've taught these kinds of things in my course on human nature for 16 years. What the students come out with on the catwalk -- we'll see. Hopefully, it will be both good and fun."
