(Reuter, Rachel and Lobert, Lauren) There are also other causes for releaser pheromones. For example, female rabbits and some other mammals release a scent that tells their minor is ready to breed. This scent then causes their young to instantly begin nursing. As for the others, Primer Pheromone causes a slight change in the endocrine system of the animal sustaining it. Some animals, including mammals like rats, unfetter pheromones that cause sexual behavior in the opposite sex. Females release an aroma that attracts a male and provokes him to cause exhibit mounting behavior on the female, who is also exhibiting lordosis. The pheromones are sensed by the vomeronasal organ (VNO) in the brain. Rats are another example of Primer Pheromone. When the male rat reveals its scent to the female rat, the female rat matures faster. Also, a female rat can possibly have a miscarriage when the scent of a different male rat of a different strain is taken upon.
