Regarding my earlier post and cross-species comparisons. Mammalian
pheromones appear to activate genes in gonadotropin-releasing hormone
(GnRH) neurosecretory neurons. In mammals, including humans, alterations
in hypothalamic GnRH pulse frequency effect gonadotropin (LH/FSH)
ratios, which influence steroidogenesis and thus apoptosis,
synaptolysis, and synaptogenesis. The likelihood that human pheromones
may influence the size of the BSTc via this developmental process,
suggests that human pheromones may be involved in the development of
