The Coolidge effect is the effect of a male of a given species, in most cases, it tended to be a rodent or a rooster mating. And at some point reaching exhaustion or the inability to mate again because they just simply couldn't for whatever reason. The Coolidge effect establishes that if you swap out the hen with a new hen, or the female rat or mouse with a new one then the rat or the rooster spontaneously regains their ability to mate, somehow their vigor is returned, the refractory period after mating that normally occurs is abolished and they can mate again.
