Human Pheromones: theory vs models

the prenatal migration of GnRH neurosecretory neurons allow human pheromones to effect GnRH pulsatility, which modulates the concurrent maturation of the neuroendocrine, reproductive, and central nervous systems, thus influencing the development of human reproductive sexual behavior and other behavior.
