Mouse Pheromones Are like a Peacock's Tail (image) University of Utah Share Print E-Mail 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.
