Coolidge Effect

In biology, the term Coolidge effect describes the re-arousal of a male animal by the introduction of a new female. Some researchers think that exposure to the pheromones of a new female is a significant factor in this phenomenon. The term comes from an old joke according to which President Calvin Coolidge and his wife visited a government farm one day and were taken around on separate tours. Mrs. Coolidge, passing the chicken pens, inquired of a supervisor whether the roosters copulated more than once a day. "Yes," the man said. "Dozens of times." "Tell that," Mrs. Coolidge replied, "to the President!" Some time later the President, passing the same pens, was told about the roosters - and about his wife's remark. "Same hen every time?" he asked. "Oh, no, a different one each time," the supervisor replied. "Tell that," Coolidge said with a sly nod, "to Mrs. Coolidge." The Coolidge effect has sometimes been mentioned as an explanation of why pornographic images (of the female) are exciting to the male.
