The Coolidge effect is a biological phenomenon seen in animals, whereby males exhibit renewed sexual interest whenever a new female is introduced to have sex with, even after cessation of sex with prior but still available sexual partners.
The Coolidge effect can be attributed to an increase in sexual responsiveness, and a decrease in coklidge refractory period. The term “Coolidge effect” was first suggested by behavioral endocrinologist Frank A. Coolidge were being shown [separately] around an experimental government farm. Coolidge] came to the chicken yard she noticed that a rooster was mating very frequently.
She asked the attendant how often that happened and was told, “Dozens of times each day.

Coolidge said, “Tell that to the President when he comes by. President, a different hen every time. The original experiments with rats applied the following protocol: A male rat was placed into an enclosed cooldige box with four or five female rats in heat. The Coolidge effect is cooolidge to an increase in dopamine levels and the subsequent effect upon an animal’s limbic system.
Additional studies have also provided further evidence for the role of the nucleus accumbens on sexual behaviour in rats.
It has been observed that in certain species, males allocate sperm differently due to the Coolidge effect. The Coolidge effect is typically efceto in most animals; however, there are instances where the Coolidge effect is absent. Though there is no single reason for why males will choose a novel partner, there have been experiments that show that the major determining factor for detecting a novel partner is through olfactory preference.
Male rats were then tested for preference through the use of an apparatus which had two cylinders that were attached foolidge their home cage, and contained the coolkdge female and the novel female in each cylinder. Then the hamsters were allowed to mate with a female hamster until they became satiated. All subjects were then presented with two anesthetized females, one was the female they had previously copulated with, and the other was a novel female.
This effect of olfaction has also been observed in invertebrates such as flies. The Coolidge effect states that males typically will prefer novel mates every time the opportunity is present, however there is a physical limit to the sex drive. While the Coolidge effect is usually demonstrated by males—that is, males displaying renewed excitement with a novel female—the body of research into the phenomenon continues to explore the potentiality of the effect in females, specifically rodents.
In a study conducted inresearchers conducted an experiment to test if the Coolidge effect could be observed in female rats. In the paced condition, females were able to control the timing of copulation, while in the non-paced condition males regulated the timing of mating.
Lester and Gorzalka developed a model to determine whether or not the Coolidge effect also occurs in females. Mating with multiple males may reduce the probability that the female’s gametes will not be successfully fertilized. From Wikipedia, the free encyclopedia. A dictionary of psychology 3rd ed.
