A US student is said to be distraught after a PowerPoint presentation detailing her sexual conquests went viral.

Karen Owen, a 22-year-old student of Duke University, North Carolina, detailed her exploits with 13 men, reports the Daily Telegraph.

She produced the unofficial 'senior honours thesis' on her flings as a joke to be shared with three close friends after she graduated in May.

But it was subsequently leaked to the university's 14,000 student population before becoming a global viral hit.

The 42 page presentation is titled 'An education beyond the classroom: excelling in the realm of horizontal academics'.

Miss Owen, from Connecticut, graphically describes her lovers, how they met in bars and what they did after their binge drinking sessions.

Each of her 13 lovers is named and pictured. She details their 'pros' and 'cons' and ranks their sexual prowess out of 10 in coloured charts.

Miss Owen is said to have been left devastated by the scandal and told The News of Today website: "I regret it with all my heart."

"I would never intentionally hurt the people that are mentioned on that." Her family later declined to comment.

A University spokesman said officials were "reaching out to those who've been affected by this incident".
