A Nobel laureate whose comments about the "trouble with girls" involved in science sparked an outcry has resigned from University College London (UCL).
Sir Tim Hunt, who was awarded the Nobel prize in physiology or medicine in 2001, yesterday apologised for any offence caused by his remarks at the World Conference of Science Journalists in South Korea.
He held the role of honorary professor with the UCL Faculty of Life Sciences but the university confirmed he has resigned.
A statement said: " UCL can confirm that Sir Tim Hunt FRS has resigned from his position as honorary professor with the UCL Faculty of Life Sciences following comments he made about women in science at the World Conference of Science Journalists on 9 June.
"UCL was the first university in England to admit women students on equal terms to men, and the university believes that this outcome is compatible with our commitment to gender equality. "
He is reported to have told the conference: "Let me tell you about my trouble with girls. Three things happen when they are in the lab: you fall in love with them, they fall in love with you, and when you criticise them they cry."
The Royal Society, of which Sir Tim has been a fellow since 1991, has already distanced itself from the comments, which sparked a backlash online.
Speaking to the BBC yesterday Sir Tim insisted his remarks were intended to be funny, but reflected that it had been a "very stupid thing to do" in the presence of many journalists.
"I did mean the part about having trouble with girls. It is true that people - I have fallen in love with people in the lab and people in the lab have fallen in love with me and it's very disruptive to the science because it's terribly important that in a lab people are on a level playing field.
"I found that these emotional entanglements made life very difficult.
"I'm really, really sorry I caused any offence, that's awful. I certainly didn't mean that. I just meant to be honest, actually."
Defending his remarks, he added: "It's terribly important that you can criticise people's ideas without criticising them and if they burst into tears, it means that you tend to hold back from getting at the absolute truth. Science is about nothing but getting at the truth and anything that gets in the way of that diminishes, in my experience, the science."
Sir Tim reportedly described himself as a "chauvinist pig" and argued in favour of single-sex laboratories at the talk in South Korea.
Connie St Louis, a lecturer in science journalism at City University, was in the audience when Sir Tim made the remarks and described the experience as "awful", adding that his comments were greeted with silence.
"A lot of my colleagues sat down and were taking notes because they couldn't believe in this day and age that somebody would be prepared to stand up and be so crass, so rude in a different culture and actually to be so openly sexist as well."
