Mouse Pheromones Are like a Peacock's Tail

Caption: Male mouse pheromones, or sex attractants released in urine, attract female mice and increase the male's chance of mating and producing offspring. In that way, mouse pheromones act much like a male peacock's tail to attract mates -- an idea depicted in this illustration. Male mice end up producing more pheromones if their mothers had access to many mates, compared with sons of monogamous mothers, according to a new University of Utah study.
