Dr. Lazar Greenfield, an emeritus professor of surgery at the University of Michigan, resigned as president-elect of the American College of Surgeons (ACS) after writing a controversial editorial in a February issue of Surgery News. Greenfield also served as the lead editor for ACS' content in the publication - a post he has also resigned.
The editorial suggested that semen has a mood-enhancing effect on women. It concluded, "so there’s a deeper bond between men and women than St. Valentine would have suspected, and now we know there’s a better gift for that day than chocolates."
The entire February issue of Surgery News was retracted by ACS after receiving complaints.
